A casserole for even the pickiest eaters

I really don’t like being a picky eater, but I am. Yes, it’s true… I can’t stand onions. They gross me out. BUT, having said that I actually like french fried onions… maybe the fact they’re breaded and fried makes them okay. 😉

This next recipe I’m sharing is topped off with those delicious french fried onions and filled with all sorts of goodness like chicken, cheese, sour cream, mayo and almonds. It is DELICIOUS!

The best thing about this French Onion Chicken Casserole is that it takes little prep time. Literally, it takes minutes to throw together if your chicken is already made. You can buy cooked, chopped chicken, but I like to bake my chicken earlier in the morning.

10 minute prep

Although it takes awhile to bake, it really only takes about 5 minutes of prep work. Add that with the 5 minutes it takes to put this casserole together and you’re looking at about 10 minutes of work.

PREP. Preheat oven to 350 and coat a 9×13 baking dish with cooking spray.

BAKE. In large bowl, stir celery, cheese, sour cream, mayo and cream of chicken. Add chicken and almonds. Spoon into dish. Bake uncovered for 30 minutes.

TOPPING. Sprinkle fried onion and cook another 5 minutes. Let stand 5-10 minutes. Enjoy!

Tips + variations

Here are a few ideas to tweak the recipe to make it a little more healthy:

  • Use a low fat Mayo and sour cream
  • Substitute all or a portion of the Mayonnaise with a low fat Greek yogurt 
  • Add veggies—sliced carrots, peas, broccoli florets, and shredded zucchini are all good choices 
  • Make it even more keto friendly and sprinkle cooked chopped bacon bits on top
  • Serve over white or brown rice, pasta, cauliflower rice, or zucchini pasta

Serve French onion chicken casserole with any of the following:

Storing info

To make ahead of time, assemble and cover with plastic wrap and store in the fridge for a day. If freezing, then add another layer of aluminum foil and freeze for 2-3 months. Thaw overnight in the fridge before baking. Do not add the fried onions until the last 5 minutes of baking time.

To STORE, divide the leftovers into single serve portions. Store the portions in  airtight containers and keep in the fridge for days. To reheat quickly, use the microwave. If you have a little more time reheat in the oven.

The fried onions may become mushy as it sits in the fridge. To crisp them back up simply stick the casserole under the broiler. Watch carefully as they can go from soggy to burnt really quickly.

    This dish was easy! Came out delicious! Will definitely make it again.

    1. Lil' Luna Team says:

      I’m so thrilled you enjoyed the recipe.

  2. Amy Worth says:

    One of our favorite dishes. I like to add parboiled asparagus to this recipe.

  3. Susan says:

    5 stars
    I made it for company and they loved it. Excellent recipe

  4. Alexis says:

    5 stars
    Added onion, subbed sour cream w/ table cream. Didn’t use celery or almonds. Turned out pretty good 🙂

  5. Ingrid says:

    I wonder if we could add fresh chicken thighs and drumsticks with all the other ingredients cover with foil for about 1 hour cooking slow on 350• then uncover adding the crispy onions😊What do you guys think.

  6. Jen says:

    For me it’s not the ads that are blocking the screen, it’s the pink banner with the “featured in” bubbles. I understand you need the ad revenue – that’s fine – but please find another way to display “featured in”. I’m sure it’s a turnoff to many and it’s a shame because this site has great recipes/content otherwise!

    1. Jill says:

      Agreed…I really like this dish but its such a hassle to need to go back to the recipe and have to get 2 lines of text because the “Featured in” section is blocking it. I don’t care about what you’ve been featured in if I can even read your recipes.

  7. Ashley says:

    You need to address the ads. I can’t scroll up because it triggers a drop down. Even if I refresh the page is keeps me at my location and if I attempt to scroll up same thing happens.

  8. Vona says:

    I want to make this but this post is ##%%^€# annoying. All kinds of pop ups for other recipes in the way of reading it. Waaaayy too many ads.

  9. Doctor Grandma Jeannie says:

    I mutilated the recipe, but it came out fabulous! I’m sure it would have been good as written. but I forgot cheddar and almonds, read reviews and just played with it. The celery added a nice crunch factor, as did the green beans and the (few) FF onions that I mixed in. I also added onions, mushrooms, and carrots that I sauteed in bacon drippings. I put in a layer of raw rice and a cup of bouillon (BTB), but the rice was not fully cooked even after 45 min. Might par-boil it next time. Overall, it was a very forgiving and flexible recipe, and very tasty! Thanks. We enjoyed it.

  10. Doctor Grandma Jeannie says:

    I’m about to try this recipe. However, it has been a BIG struggle to use your website. The “Featured in” screen overlays your blog/recipe, covering OVER 3/4 of my screen. I can only read a maximum of 5 lines of text, or see an inch or so of a picture (on a big laptop screen). It will retract if I scroll down, but if I scroll up it just drops down again. This is not helpful, and is very discouraging. It just makes me want to give up and go to a website where I can actually read the recipe! I suspect you are losing a lot of readers because of it. I like your recipes, but this is a PITA. (Pain in …)

  11. Stephanie P says:

    My apologies – the ads are preventing me from getting back to my comment to reply to it. I see that the ad comments were recent, not from several years ago.

  12. Stephanie P says:

    I can see that others have told you, but this is several years after those comments and we’re still having the same issue. Just wanted to let you know that it’s still happening. The “Featured In” drop down prevents you from scrolling back up (when viewed on a mobile device). I requested to view it as the Desktop version, but it still happens.

    1. Lil'Luna Team says:

      Hi Stephanie! Thanks for the feedback. We’ll look into it…. I am still able to see the post after scrolling down a bit. Are you completely unable to see the post?

  13. Chelsey says:

    would love this, but all the ads and pop ups made it impossible to see the recipe.

    1. Lil'Luna Team says:

      Thanks for the feedback. The ads enable us to be able to provide free content and recipes for our awesome readers. Thanks for understanding. 🙂

      1. charlene says:

        Your losing viewer as a result. Is it worth it?

    2. Ashley says:

      I loved this recipe and came back to the site to make it again but after 10 minutes of fighting with the ad/banner to see the recipe I gave up and went elsewhere. Frustrating!

      1. Lil'Luna Team says:

        Thanks for the feedback. The ads enable us to be able to continue to provide free recipes and content for our readers. Thanks for understanding! 🙂

      2. Wendy says:

        But the ads are preventing us from seeing your recipes. Please change your banner so it doesn’t block out the recipes!

      3. LilLunaTeam says:

        Thank you so much for bringing that to my attention. I will definitely see if there is a way to arrange the ads better so that the readers can see the recipes.

    It’s a keeper because my Iowa born, I only like potatoes, beef and corn husband liked it!

    The French onions and almonds really make a generic chicken casserole shine. Really great combinations.

    Our family does enjoy casseroles. There hearty and can feed plenty. Plus, there simple to make.

  21. Joy says:

    I have never been the hugest fan of this dish, but I devour your recipe!! It’s so creamy & tastes so good & my favorite are the fried onions on top!

  22. Nicole Ruffner says:

    Would I be able to sub Greek yogurt for the Mayo ?

    1. Lil'Luna Team says:

      Sure! It might alter the flavor a bit, but would lighten up the calories!

  23. Shari says:

    Love this recipe! Can it be frozen? and would you freeze it before or after you bake it?

    1. Lil'Luna Team says:

      Yes, it can! If freezing, cover with plastic wrap, then add another layer of aluminum foil and freeze for 2-3 months. Thaw overnight in the fridge before baking. Do not add the fried onions until the last 5 minutes of baking time.

  24. Anna says:

    Love this recipe! I’m making this for a meal train for 6 adults & 1 child. Do you recommend making 2 casseroles or would 1 be enough? Also, they live about 40 min away. I was planning to make it the day of & then drive it over there. Would they just need to put it in the oven under broil for a few minutes?

    1. Lil'Luna Team says:

      I think that 1 casserole would probably be enough. The recipe written serves 12, but you can adjust the serving size on the post as well, right above the ingredients. I think 1 casserole would be just the ticket. And yes, if the casserole has cooled off too much for their liking, they certainly could pop it back in the oven for a bit. Either at 350 to heat a little more or if the top just needs crisping again, then it could go under the broiler.

    Just wanted to drop a note to tell you I absolutely
    LOVE this recipe! I have made it countless times. Thank you for publishing/sharing!

    1. Lil'Luna Team says:

      Oh thank YOU so much for sharing your thoughts! I’m so glad you love this recipe!!

  26. Monica says:

    Haven’t made this yet but sounds great! quick question, I don’t have cream of chicken on hand can I use chicken gravy?

    1. Kristyn Merkley says:

      Thank you! You know, I have never tried, but I am sure that would work 🙂

    2. Jennifer says:

      My family loves this casserole, I make it a lot.
      I was wondering if I could make it in the crockpot?

      1. LilLunaTeam says:

        I haven’t tried this recipe in a crockpot yet but I do think it would work out well. I would try cooking it on low for 3-4 hours and then sprinkle the french onions on top at the very end just like in the oven version of the recipe. I hope this helps!

  27. Carolyn says:

    Great casserole, family gave it thumbs up and it’s a keeper.

    1. Kristyn Merkley says:

      Yay!! Tell them, thank you!!

  28. Kathy Phillips says:

    I wouldn’t have thought all of 5these ingredients would go together.

    I made it without the celery or green beans. It was really good and the almonds were like a nice surprise and crunch in every bite!

    1. Kristyn Merkley says:

      Thanks for sharing that!

    I DID MAKE A FEW CHANGES: i WAS OUT OF SOUR CREAM, SO I THREW IN A CAN OF CREAM OF MUSHROOM INSTEAD, AND THEN I THOUGHT WHY NOT THROW IN SOME MUSHROOMS TOO!

    aS WRITTEN, i THINK THE RECIPE WOULD HAVE BEEN JUST AS TASTY though. Family loved it! We will definately make this again!

    1. Liz says:

      Didn’t mean to yell! lol

      1. Liz says:

        5 stars
        Did finally make this with sour cream and it was still really good! We’ve also been putting a can of green beans in and love it. I’ve made this a few times in the last few months- it’s one of my favorites now!

    2. Kristyn Merkley says:

      Glad to hear that!! Great options! Thank you!

  31. Kristin says:

    ok question. Haven’t made this yet but interested as I love fried onions! But one ingredient has me stumped. Never heard of slivered almonds in a casserole type dish. Do they stay solid and crunchy or do they soften and just blend in for flavor?

    1. Kristyn Merkley says:

      They do stay solid & they will still have a little crunch. They may soften a little. Hope you like it!

  32. Kathy says:

    Love this recipe! SO EASY TO PUT TOGETHER. i HAVE MADE THIS SEVERAL TIMES AND IT NEVER DISAPPOINTS!

    Just FINISHED eating this. A bit too much mayo. I Seasoned the CHICKEN with garlic powder, onion powder and paprika. The casserole i added frozen peas and carrots. I also seasoned the casserole with some dried paRsley and thyme. I will try this again and Reduce the mayo.

    This recipe is a total Hit in my family!

    I have made some tweaks that brings this casserole to the next level:

    1) i always use Frozen cut greEn beans for an added “crunch”
    2) i mix about half of the french onions into the casserole (a la green bean casserole)
    3) at the end of cooking, i mix A cooked bag of egg noodles into the casserole and cook for five minutes on broil

    1. Kristyn Merkley says:

      Thanks for sharing what you did! Sounds great!

  37. Katie says:

    Extra cup-2 cups chicken
    Green beans instead of celery
    Dashes of
    garlic powder
    Onion powder
    Cayenne powder
    Pepper
    Salt

    Hubby loves it and request it being part of a regular rotation

    Thank you!

    1. Kristyn Merkley says:

      Sounds delicious! Thank you for sharing what you did!

  38. Amber says:

    Does this need a large or small can of cream of chicken?

    1. Kristyn Merkley says:

      It just needs the one that is around 10 ounces 🙂

    This was so delicious. EVen my picky 13-year Old eater was going back for seconds.

    1. Kristyn Merkley says:

      I’m not familiar with the substitutions for sour cream for lactose intolerant..what would you normally use?

  43. Aleene Simpson says:

    Wow, this recipe sounds so good. It might even be better with parmesan cheese as well as cheddar in the recipe.. To make it a notch up from the already goodness of it. Thanks for the recipe.

    1. Kristyn Merkley says:

      That would! I am glad to share! Thank you so much!

    1. Traci Layne Phillips says:

      I can’t fix my all caps, sorry.

    It has really good flavor. I cut 4 chicken breasts into bIte size pieces and made plain (just Salt and pepper) macaroni on the side. Next time i would half or 1/4 the mayo and sour cream. Just too rich and creamy for my family.

    I’ve made this 5-6 times. Soooo yummy. I have made it with celery, fresh BROCCOLI, and canned green beans and they all turned out great, I personally pole green beans bc it reminds me of green bean casserole which I only eat around the holidays. Maybe it’s not the “healthiest”…casseroles usually aren’t, in my experience, but it’s such a great comfort meal, like Mac n cheese or meatloaf.

    1. Kristyn Merkley says:

    I just made this and found it easy & delicious. I halved the recipe, as I’m collecting recipies for 1 or 2. I used leftover rotisserie chicken & baked in a glass loaf pan. It was a bit salty for me, so I’ll look for a low sodium soup next time. Loved the crunch of the nuts & french fried onion rings!

    1. Kristyn Merkley says:

      I am glad you liked it 🙂 Halving is perfect for 1 or 2. Thank you for letting me know!

  65. Patricia says:

    Can I use rice instead ?

    1. Kristyn Merkley says:

      Haven’t tried, but why not? 🙂 That would be good!

  66. Mary Gwen says:

    This same recipe was served at a dinner party , and the hostess had added chopped green chiles which really zipped it up! That sets it apart from an ordinary chicken casserole.

    1. Kristyn Merkley says:

      That would be a great addition 🙂

    This recipe is great for low-carb dieters. I made this dish with 4 chicken breasts, 1/2 cup mayo, and the rest of the ingredients listed. Tasty!

    I feel like this would be even more delicious with a crescent roll crust on the bottom!

    1. Kristyn Merkley says:

      You could totally try! That is what’s great about cooking!

  71. Cathy says:

    Too much liquid. I added wide egg noodles and would still cut the sour cream and mayo to 1/2 cup each. Also added peas instead of green beans and bacon bits.

    I think Joyce’s comment was very rude as well! There are a lot of things you can do to take out some of the fat. You can use light sour cream and mayo. They even sell heart healthy cream of chicken soup. Just about all recipes can be tweaked for ones dietary life style. Anxious to make this!

    Excellent casserole! I did not have celery or green beans so I threw in a bag of sweet peas and celery seeds! Love it!!

    1. Kristyn Merkley says:

      Great backup choices! Glad you liked it! Thank you so much!

    Thanks for sharing! I loved the idea, but wanted to slim it down a bit. It’s only me and my husband so I didn’t want to make too much! I used one 12 oz chicken breast, one can of cream of mushroom (it’s what I had in the cupboard), one can of French style green beans, about 1/2 cup cheese and about 1/2 a can of french’s Fried onions, some mixed in and the rest on top. We put the casserole over some rice. It came out perfect! Super yummy! Can’t wait to have leftovers for lunch tomorrow!

    1. Kristyn Merkley says:

      Thanks for sharing your changes!! Sounds great! Glad you both liked it!

    Really good with green beans. I would just cut back the onions a little the whole container is a bit much.

    1. Kristyn Merkley says:

      Green beans are a great choice! You could definitely add as much or as little of the onions, as you like 🙂 Thank you!

  76. Kathryn says:

    So good!! Did fresh green beans and it added a great crunch

    1. Lil' Luna says:

      Great idea and thank you so much for letting me know!

  77. Christy says:

    My husband was very pleased with this dish. I only used a half of stock of celery and a can of mixed vegetables. I also added a little poultry seasoning and garlic and herb seasoning. Very good recipe.

    1. Lil' Luna says:

      Thanks so much!! I’m glad you liked it and your changes sound great!

  78. Erica says:

    Huge difference without the slivered almonds? I hardly ever buy those and hate them just sitting in the cabinet for the next recipe I use them with. Can’t wait to make this with the green beans!

    1. Lil' Luna says:

      Those go great with oriental salads! But, you don’t have to add them 🙂 Let me know what you think 🙂

  79. Kathi says:

    Just made this for dinner tonight and it was very good. Made it with the French green beans instead of the celery, and since husband doesn’t like mayo baked in anything, I substituted it with a cup of Cambells nacho cheese soup. Also added some onion powder. It was a big hit and will be one recipe I’ll make again.

    1. Lil' Luna says:

      Sounds good! Thank you for sharing 🙂

    1. Lil' Luna says:

      You can do it 🙂 Thank you for stopping by and let me know how they turn out!

      1. Nicole says:

        Can you use miracle whip in place of regular mayo?

      2. Lil' Luna says:

        I haven’t tried, but if that’s what you like, doesn’t hurt to try! Let me know what you think 🙂 Thank you!

      3. Sandy says:

        Miracle Whip has sugar in it.
        I wouldn’t suggest using it.

    I have made this several times, each time tweaking it just a little for our family’s liking 🙂 The 1st time I followed the recipe exactly as is, it was very soupy! I am in weight watchers so I changed up a few things to make it a little healthier. The few changes I used were:
    green beans instead of celery (pure preference)
    Cut out the mayo completely (honestly couldn’t even tell)
    Used Greek yogurt in place of sour cream, dont use quite a full 1/2 cup

    So for whoever had negative comments, the way I made it was very healthy, contained chicken, Greek yogurt, green beans, cheese and 1 can of soup, most of which are healthy items 🙂

    Thank you Lil Luna for the great recipe!

    1. Lil' Luna says:

      Oh, thank you so much for sharing that!!! I’m so glad you found a healthier alternative 🙂

  84. Jody says:

    5 stars
    Thanks for the great dinner idea. To make it a little healthier I used 1 and 1/2 cup lite sour cream and 1/2 cup lite cream cheese instead of mayo. It still came out so creamy. This one’s a keeper, thanks!

    1. Lil' Luna says:

      Thanks for sharing those healthier tips!! I am so happy to hear that you liked it!

  85. Karen K says:

    What would you recommend serving with this? Sounds delicious.

    1. Lil' Luna says:

      You can serve a vegetable, like zucchini or asparagus, a roll..maybe some chicken. Hope those help! Thank you!!

      1. Jane Marshall says:

        I made this recipe with the french style green beans and won for best side dish at my work. I have so many co-workers that are asking for the recipe. 🙂

    I’ve made this twice now. The first time had too much mayo. I cut it in half and substituted more sour cream. Much better the second time! The men in my house really like it.

    1. Lil' Luna says:

      I’m so glad they liked it!! I’m glad you found a way to substitute the mayo. Thank you so much for sharing!!

  87. Laura says:

    This was amazing! Made long grain rice and put this over the rice and it was fabulous! And super easy! 5???? In my book.

    1. Lil' Luna says:

      Great!!! Thanks so much for letting me know! I’m glad it was a hit 🙂

  88. Heather Mulligan-Gonzalez says:

    I bulked this up with 2 cups cooked pasta and 8 strips thick cooked bacon, chopped up. It is my family’s go to comfort food!

    1. Lil' Luna says:

      Sounds amazing!! Thank you for sharing..I’ll have to try that!

    This one is a keeper! Husband loved it! I don’t understand the comments from the folks who said theirs was soggy. Mine came out perfect. I’m going to stash some of these in the freezer, and add the onions at the end. BTW, I added some of the french fried onions into the actual casserole. Yum!

    1. Lil' Luna says:

      That’s so good to hear! Thank you so much for sharing!!! I’m glad you liked it!!

  91. DeAnna says:

    Anyone ever try this in the crockpot? I love recipes that I can through in in the morning and this seems like it would work. Just through everything in except thr onions until the last 30 minutes or so?

      I’m glad you think so!!! Thanks so much for letting me know what you thought and for giving it a try!!

  93. Rachel Stultz says:

    I made this tonight with the following changes: added 1/4 cup chopped onion, replaced half the mayo with cheddar cheese soup (Campbell’s canned), added 1 tablespoon garlic powder, 1 tsp black pepper, and sprinkled a little cheddar over the top along with the French onions and used light versions of the sour cream and mayo. It ended up being 8 servings at 361 calories per serving. Definitely not a crazy calorie number for something like this. It was DELICIOUS!!!! Thank you for sharing this wonderful recipe! We’ll definitely make it again!

    1. Lil' Luna says:

      You’re welcome!! I’ll have to try with your changes!! Thanks so much for sharing!!

  94. Janel says:

    Made this last night. I used green beans and celery. It was very good. Next time I think I will add hash browns too. Very good recipe as is!! Will definitely make it again!

    1. Lil' Luna says:

      That sounds great!! I’m so glad you liked it!!! Thanks so much!

  95. AM says:

    My mother made this for my husband and I to eat after the birth of our son. She gave it to us frozen, cooked, with the onions to add to the top after we reheated it. We’ve eaten a million casseroles in the last month, and this is the winner!! It is incredible, we served with green beans on the side and I will make it again soon.

    1. Lil' Luna says:

      I love when I find winners!! So glad you liked it! Thanks a lot!!

  96. Connie says:

    I just made onion chicken casserole Sorry but it was to soupy and mayo was to over powering

    1. Lil' Luna says:

      Sorry it didn’t turn out quite how you thought. Haven’t had it come out soupy, so wondering what made it that way. If you like something other than mayo to substitute you could or maybe use a little less. Hope you’ll try it again 🙂

  97. Amanda says:

    Going to make this for a friend who lost her husband and I want her to be able to freeze it. If I do the first round of cooking and then add the onions part, will that work? Or will they burn when she heats it back up? Any suggestions most welcome. This looks like a good chix casserole but wanted to make something she could freeze in case she has too much food already. Thanks!

    1. Lil' Luna says:

      So sorry to hear that!! I haven’t put it in the freezer yet, but I would maybe leave the onions off and give those to her separately to add on. That is only if you are wanting her to freeze it & not eat it, right away. Hope that helps!!

      1. Amanda says:

        Good idea, thanks!

  98. Coleen says:

    I used French style green beans instead of the celery, and added mushrooms and penne pasta. It was a little dry. I think baking it covered would help or increase wet ingredients to 1 1/2 cups. Tasty.

    1. Lil' Luna says:

      Maybe the pasta soaked up all the wetness? I haven’t added pasta before, but it usually isn’t dry. I’m glad you think it’s tasty!! Thanks for sharing!

  99. Riss says:

    Came out fantastic…. but in order for it to be a “casserole” rather than “soup”…. cook it longer….

  100. Tess says:

    Just a hint for those who don’t like “real” onions. To keep the real onions and flavor, AND to please the picky eaters, I use a cheese grater to grate the onion into soups, stews, and casseroles.

    1. Lil' Luna says:

      Thanks for sharing that tip Tess! That would be me 🙂

    This was really good! I made it with a can of french-style green beans instead of the celery. My whole family liked it. Even my two little kids, ages 3 and 6, who don’t normally like regular green-bean casserole ate it. (They were hesitant at first but once they tried it, they cleaned their plates!) My 11yo has requested that I make it again for sure!

    1. Lil' Luna says:

      LOL..I’m glad they cleaned their plates!! We love this! I’ll have to try it with the green beans:) Thanks so much!

  102. Holly says:

    Hi! This looks delicious. Do you know how many carbs per serving on it in? I’m on a low carb diet, but want to try this!! 🙂

    1. Tracey says:

      I am going to make my own cream of chicken …. with that said it will be fairly low carb with lots of fat!!!!

  103. Sunny says:

    This looks delicious – can’t wait to make it! When you listed ‘cream of chicken’ in the ingredient list do you mean a can of cream of chicken soup and if so do I add water or anything to it?

    1. Lil' Luna says:

      It is!!! Yes, it’s just a can of cream of chicken soup and you add it with the other ingredients in step 2. Hope you like it!

  104. Bonnie says:

    Kristyn, I have a question. Is your grandmother Luna’s first name Jean?

    1. Lil' Luna says:

      No, it’s Ernestine:) Do you know someone with that name?

  105. Suzanne says:

    For the French onion chicken casserole, do you mean the Durkee’s fried onions in the can?

    1. Lil' Luna says:

      We use French’s… haven’t seen Durkee’s before but yes, they are fried crispy onions. 😉

  106. Kelsey says:

    Tried this tonight and it was amazing! I added a few things to it. I put a layer of white rice on the bottom of the 9×13 pan. Then I added sauteed onions, carrots in addition to the celery. It was amazing!

    1. Tracy says:

      Did you cook the rice first? If not, did you use instant rice? I love the idea of rice, I’m just not sure how to incorporate it. My chicken dishes always end up dry…

      1. Lil' Luna says:

        I didn’t use rice in this recipe, but you could probably serve it over minute rice and it’d taste good. It’s whatever you prefer:)

  107. Joyce says:

    This is probably good, but I can’t see any reason for it; that is, there is nothing added but a lot of high fat, no-reason mayo, sour cream, french-fried onions, and a bit of celery. If it had VEGETABLES, and maybe either rice or noodles of some kind, it might be worthwhile, but as it stands here, I’d feel as if I was swallowing nothing but mayo and sour cream–both of which I like, in their places–without gaining one bit of real nutritional value.

    1. Leslie says:

      Here’s a thought, maybe just scroll past it, without your condescending and rude comment! Good grief….

        I agree! Joyce, no one is forcing you to make/eat this! I think it looks yummy! Not exactly heart-healthy, but we’re adults here and can decide for ourselves.

      2. Lil' Luna says:

        You can always take things out or add what you like. That’s whats great about recipes. If you know healthier substitutes, then add those and share what you tried. I’d love to know, so we can pass that along:)

      3. Kristy says:

        I’m looking to make this as well! That does seem like a lot of mayo… if I take some out do you think it will be missed? And a good substitute for sour cream is plain greek yogurt! I use that on my taco/mexican dishes and you can NOT tell a difference.

      4. Lil' Luna says:

        You definitely don’t have to add as much! I don’t know if that will change anything, since I haven’t tried. And, yes, greek yogurt is a great substitute!! Let me know what you think!! Thanks a lot!

      5. Gail says:

        Agree. Can’t stand someone lingering with snide remarks when it isn’t necessary. Why did you come on here? Not every recipe is for everybody. No need to pretend you are superior and to be rude to the poster over the recipe and others who like it. I generally don’t make comments on Pinterest related sites, but the rudeness is provoking, but then maybe she wanted it that way???

    2. Cassie says:

      I don’t usually comment, but this is by FAR the RUDEST most unwarranted comment I have EVER seen from a grown adult! If you “see no need for it” then don’t make it and move along!!! It’s one thing to comment saying you made it and weren’t pleased, or even comment offering up suggestions and changes, but to come here lecturing people with your want-to-be professional dietician opinions is ridiculous! If YOU don’t like it, don’t make it! But don’t think for a second that your snooty comment is going to prevent others from making it! Goodness, go find some happiness in your bitter life!

      1. Kristine says:

        Well said!!!

      She HAs a list of suggestions for making the recipe healthier, like substituting low-fat mayo, low-fat sour cream and one can even substitute low-fat, heart healthy cream soups. There are all kinds of ways to make this healthier, so how about reading the entire post before making your rude comments.
