A simple and delicious recipe for French Onion Chicken Casserole - just 10 minute prep time and you have a delicious dinner recipe! { lilluna.com }

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 because they’re breaded and fried makes them okay. Not sure just yet, but all I do know is that I can eat them (and LIKE them) without gagging like regular onions. πŸ˜‰

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!

MY OTHER RECIPES

The best thing about this French Onion Chicken Casserole is that it takes little prep time. Literally, it takes about 5 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. I usually line a cookie sheet with foil, add some chicken breast and drizzle a little bit of olive oil and lemon pepper. I cook at 400 degrees for 35-45 minutes (depending on the thickness of the chicken breast). I let it cool and then chop it up real quick. 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.

Can’t beat that!

We used celery for this recipe, but I think I’ll try French Style Green Beans when I make it next. I think even broccoli would be a great addition!

Making this next week for dinner! Looks tasty!

Sara @ Bitz & Giggles

Kristyn, this looks SO good! Pinning and making for my family for sure!! I adore French Fried onions in savory dishes!

Leslie

This looks amazing. Pinning it now.

Sarah

I made this recipe the other night. It was so good! Next time I think I’ll add some of the hash brown potatoes

Joyce

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.

    Leslie

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

      Bonnie B

      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.

        Lil' Luna

        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:)

          Kristy

          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.

          Lil' Luna

          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!

      Gail

      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???

      Rhea Martin

      Yes, exactly Leslie! Or how about just don’t make it then.

    Cassie

    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!

    jet

    Totally agree.

Kelsey

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!

    Tracy

    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…

      Lil' Luna

      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:)

Suzanne

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

    Lil' Luna

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

Bonnie

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

    Lil' Luna

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

Sunny

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?

    Lil' Luna

    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!

Holly

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!! πŸ™‚

No Reimer Reason

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!

    Lil' Luna

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

Tess

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.

    Lil' Luna

    Thanks for sharing that tip Tess! That would be me πŸ™‚

Riss

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

Coleen

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.

    Lil' Luna

    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!

Amanda

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!

    Lil' Luna

    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!!

      Amanda

      Good idea, thanks!

Connie

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

    Lil' Luna

    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 πŸ™‚

AM

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.

    Lil' Luna

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

Janel

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!

    Lil' Luna

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

Rachel Stultz

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!

    Lil' Luna

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

Jody Russell

OMG! This is to die for! So quick,easy & inexpensive. Great flavors & not too much leftover. Thank you for sharing.

    Lil' Luna

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

DeAnna

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?

Amy

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!

    Lil' Luna

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

Heather Mulligan-Gonzalez

I added bacon and bulked it up with 2 cups cooked pasta. It has become my family’s go to comfort food!

Heather Mulligan-Gonzalez

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!

    Lil' Luna

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

Laura

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

    Lil' Luna

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

KittyBlaze

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.

    Lil' Luna

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

Karen K

What would you recommend serving with this? Sounds delicious.

    Lil' Luna

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

      Jane Marshall

      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. πŸ™‚

        Lil' Luna

        Yay..that’s awesome!!! I’m glad it was a hit. Thanks for sharing!

          Denise Warth

          I just made this and my family absolutely loved it! Served tomato cucumber salad and Hawiian rolls on the side. So easy to make and delicious. Thanks so much!

          Lil' Luna

          That makes me so happy! Thank you for sharing!

Jody

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!

    Lil' Luna

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

Echo

I have made this several times, each time tweaking it just a little for our family’s liking πŸ™‚ 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 πŸ™‚

Thank you Lil Luna for the great recipe!

    Lil' Luna

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

Alisa

Making something new Especially such recipes it is really hard but I can do it. Thank you for Recipe

    Lil' Luna

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

      Nicole

      Can you use miracle whip in place of regular mayo?

        Lil' Luna

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

Suzanne

This is the 3rd time making this. I substitute cream of mushroom for the mayo and use the French style green beans. Delicious!!

    Lil' Luna

    Love hearing that!! Thanks so much for letting me know!

Angie

Made this tonight and the entire pan was gone!!! I left out the celery cause my crew doesn’t care for it. I added 2 cups shredded zucchini well drained. My picky husband ate 3 helpings!!!! Will definitely make again!!! Thanks!!!

Kathi

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.

Erica

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!

    Lil' Luna

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

Christy

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.

    Lil' Luna

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

Kathryn

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

Jamie Snyder

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

    Kristyn Merkley

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