Add-ins. When there is about 30 minutes left in the cooking time you can add some of these suggestions: cooked bacon bits, parmesan cheese, salsa or jalapenos, broccoli, roasted red peppers, diced cooked ham, grilled chicken, cooked hamburger, chili flakes.

Storing & Reheating. Store leftover mac n cheese in the fridge for 3-5 days. You can reheat it using the microwave: stir in 1 tbsp of milk to add some moisture, cover the dish with plastic wrap, then microwave on medium heat for 1 minute and then stir every 30 seconds until it is fully heated.

Note: Discard if left out for more than 2 hours at room temperature.

Can mac and cheese be frozen? This pasta dish can be frozen for 2-3 months. When you’re ready to use you can thaw it in the fridge and cover the dish with plastic wrap, then microwave on medium heat for 1 minute and then stir every 30 seconds until it is fully heated.

    I will never eat boxed mac & cheese again!! This was so tasty, cheesy, & the crock pot does all the work. What’s better!?

    Mac and Cheese in a Crock pot? I had to try it. My kids love it so much. It’s become my go to dish when my husband and I are headed out for dinner and I don’t really want to cook for my kids. Thanks for posting!

  4. 5 stars
    mac And cheese is always a favorite amongst the kids. Whats not to like about cheesy pasta in the crockpot. Not much effort in putting this together.

    1. Im am going to try this tonight! Do we cook the mac and cheese fully or is it going to be a little hard to compensate for the two hours in the crock pot?

  5. Did you shred the cheddar CHEESE by HAND from a block or did you buy shredded cheddar cheese? Just wondering which cheese is best for THIS Recipe!!

    1. Really, either is fine. If I have cheese that I have shredded on hand, I will use that, but sometimes for convenience I use the already shredded cheese.

    We loved this for dinner tonight! Mine Was totally done in An hour (yes, I cooked it on low). I Was wondering if you’ve ever tried not boiling the noodles? I want To make it for my daughters birthday party but i really need it To cook in 2 hrs instead of 1.

  7. 5 stars
    Making this for my 3 grandchildren always have dinner with them on Thursday night,ages6 3,5,they are my CRITICS.they tell anyone that’ll listen to them,my nana cooks really good food.

      1. Can you make this the day before and put in fridge till next day then put in crockpot to reheat or won’t it be as good? Thinking for bringing to the lake and have it done ahead of time!!

  8. I have tried a similar recipe but the cheddar cheese didn’t melt very well in the butter and “clumped” rather than marry. Is there a way to avoid this? Should I add the cheddar when I put it all into the crock pot instead?

      1. I made this an it seemed to have a grit to it ….followed directions…what could have I done wrong…taste good just a texture

    Thought of making this for Thanksgiving so gave it a trial run today. It’s a great recipe! The cheddar soup kind of grossed me out at first, but you can’t really taste it. I think the sourcream is what makes this mac and cheese special.
    The fact that it’s so easy makes it a 5/5 in my book. It a very cheesy saucy mac and cheese that thickens as it sits. The noodle to sauce ratio makes this a decadent treat for sure.

  11. Hi! I haven’t made this yet, but I have a question – have you ever cooked the pasta itself, in the crock pot? I kinda feel if I’m going to boil my noodles, I may as well do as I normally do, and after boiling the noodles, al dente, to just bake it. I will, however, try it, as it looks super creamy and YuM! Thanks so much for sharing your recipes! Happy ? Thanksgiving, doll! ?‍♀

    1. I have not cooked them in the crock pot by themselves. I usually boil them in the pot first 🙂 Sure hope you like them!! Happy Thanksgiving!

  12. 5 stars
    I’ve made this recipe over a Dozen times now and its always gotten rave reviews! So smooth and creamy! Great for a potluck or as a side dish! Pair it with anytHing!!!

    1. Not this specific recipe, but I have others on my site that are baked. Just search macaroni and cheese in the bar at the top 🙂 Hope you find one to try!

    1. I haven’t left it out before, but maybe velveeta? Or, maybe google what are some good substitutes for the cheese soup. Hope you find something 🙂

    This is probably the best homemade mac n cheese I’ve come across. It’s so creamy and cheesy! I was curious if I really needed to slow cook it for 2 hours since the noodles and cheese sauce were already made but it’s worth it.

  14. 5 stars
    So… I came ACross this recipe like Two MOnths AGo, but I didn’t get to try it until now. Let me TEll you Though… it was a hit!!! This is by far the best recipe I have EVer tried FOr homemade mac! The ingredients are simple, it’s fast and easy To put together, and it tastes amazing!!! THe cheese sauce is very thick and creamy, but NOt Too thick that makes your tounge stick to the Roof Of your mouth. I actually appreciated the FAct there was no flour added to this because other RECIPIes left the sauce tasting a little chalky. The sour cream in this mixed with the cream Of cheese soup really helped to thicken up the sauce in just the right way! I just HAd to hunt down this website so That I Could come back and leave a review! 10/10 recommend This!

    i have tried at least 5 other mac n cheese recipes and this is by far the very best–thanks so much!!!!!

  16. Hi. Do you think i could sub the sour cream with something Else? My husBand is allerigic to it. Thanks.

    1. Not sure if he is allergic to any of these, but here are some suggestions…Greek yogurt, cottage cheese, or buttermilk. You can find more online. Hope any of those help!

  17. 5 stars
    Thank you so much for this recipe!! This was my first time doing a crockpot Mac and cheese and now it won’t be my last! My very picky kiddo who only eats Kraft LOVED this! Super Simple to out together and even doubled it for a cookout today!

  18. So im making this for a party and aM preparing a little early can i keep it on watn or will it dry everything out??

  19. 5 stars
    This recipe is delicious! I added a few more noodles, and it was still super creamy and delicious. A favorite for kids and adults!

    This mac and cheese is So good. I just hosted friendsgiving before my husband’s deployment (around 20 people) and this was a Huge hit! The onLy food we didnt have leftovers of 🙂

  21. Hello! I just made this and was looking creamy but after 2 hours in the crockpot (on low) dried out! Should i make more Of the milk/cheese mixture to add in? Thanks!

  22. 3 stars
    I was kinda bummed about two things, the texture wasn’t as creamy as I was expecting, it was a little grainy. Also it didn’t make very much, definitely double the batch if you’re feeling more than 5.

  23. I haven’t made it yet. Hoping to do so today! But if I use 1 whole box of elbow macaroni, do I double the rest of the ingredients? I’m not sure how much to use if I make a whole box?

    1. I would probably double the rest of the ingredients. I would say a 1lb box is about 4 cups of dry macaroni.

  24. I’m going to be making this for thanksgiving. I am wondering what kind of cheddar cheese to use. Sharp, white, extra sharp, mild? Also can you use half evaporated milk and half whole milk? I heard evaporated milk gives a much richer flavor?

    1. I like to use sharp or medium cheddar, but really it’s a personal preference 🙂 I haven’t tried using the half evaporated milk. But, if it gives a richer flavor..I’d say it’s worth a try 🙂

      1. I just was worried about what kind of cheeses to use. I have made homemade Mac and cheese once with a Pinterest recipe and it turned out a disaster. It was super grainy. So I wanted to make sure I use the right kind of cheese. With the 4 TBLS of butter is that just unsalted block butter?

  25. What kind of grated cheese should I use? Can I used the shredded cheddar that comes in a bag or should I get a lock and shred .. would it make a difference either way? Thanks!

    1. I use bagged & I have bought a block of cheddar & shredded it. I like to use fresh cheese for pastas, but both are great 🙂

    1. I haven’t tried substituting the soup, but I would see what google suggests. I don’t want to say the wrong thing, since I haven’t tried.

    I don’t normally leave reviews but this was delicious ! Over the last few years I have been trying to find the perfect Mac n cheese crockpot recipe and I finally hit the jackpot ! About halfway through I added a little more cooked pasta b/c it seemed a little to soupy for my taste and it worked out perfect. I also added a small amount of onion , but otherwise followed the recipe. IT WAS SO GOOD ! I was nervous about trying a new recipe on Thanksgiving day but this was the most popular dish. Thank you !!

        Has anyone ever cooked this on high? If so, for how long and what was the result? Any good? This is my hands down, favorite go-to Mac and cheese and I want to make it at the beach but don’t want to have to wait so long once we get home. Thanks!

        1. I haven’t tried it on high, but you could! You’d just want to keep an eye on it so it doesn’t burn. Essentially, everything in this dish is already cooked, it just needs to warm through together. So you could essentially even make it over the stovetop. After melting the cheese and the cooking the noodles, combine over the stovetop until heated through. If you do it on high, maybe check it after 1 hour and determine if it is ready.

    My kids loved this for Thanksgiving! My son told me it was his new favorite Mac and cheese. In the crockpot, even better

  28. 5 stars
    I LOVE this mac n cheese!!! It has everything I’m looking for. I have even found that I can cook it on the stovetop very quickly also (mix sauce together, boil noodles, then add to sauce, serve). I love it as a side to sloppy joes (or even in it)!

  29. 5 stars
    This recipe is a family favorite! My kids request this Mac and cheese weekly. The cheese turns out perfectly. The flavor is delicious.

    My picky kiddos absolutely love this mac and cheese and it’s so easy to make! Already planning to make it for a Comfort Food New Years Eve night!

    Made with cream of chicken soup as I never have cheddar cheese soup on hand? I also added a splash of Worcestershire sauce because I love it with cheesy dishes.
    I think the crock pot is totally not needed. One could eat it right away once the noodles (I fully cook them and drain) are mixed with the melted cheese sauce. I placed it in a baking dish, sprinkled seasoned bread crumbs on top, and broiled uncovered for 15 minutes. I have also made this using a 16 oz package of gnocchi instead of the noodles with awesome results! A favorite add-in is a small can of Rotel (drained). A little Bleu cheese adds a delicious twist too!

  32. What size crockpot did you use for this amount? Have you ever doubled the recipe? I’m wondering if I can make a bigger batch for a crowd. 😊

    1. I used a 6-quart crockpot for this recipe. I haven’t doubled the recipe before so I’m not sure if there would be enough room in the crockpot. You should have room if you make 1 1/2 times the recipe though. Hope this helps!

  33. This was a fun base recipe. I tweaked some things. Used smoked gouda, sharp cheddar and mozzarella. I also used half milk half heavy cream (adding a fourth cup more then the recipe because it seems a bit dry when it’s done cooking). And added in some sauteed kielbasa sausage to round out the meal. I also added some dry mustard and a little cayenne too for some heat. It’s a good macaroni and cheese that my kids absolutely love!

    1. All of those additions and tweaks sounds amazing! A gourmet mac and cheese for sure! I’m so glad your kids enjoyed it. Thanks for sharing!

    1. You bet! It may take a little longer to heat all the way through in the crockpot being doubled, but should still taste the very same!

  34. 4 stars
    This was awesome!! I needed a quick mac and cheese recipe to take to small gathering yesterday. This literally took less than 5 minutes to throw together after I boiled the noodles. I was skeptical about the can of cream of cheese soup. My go-to recipe for macaroni and cheese is to make a white sauce on the top of the stove and then add the cheese, boil the macaroni mix it together and then bake it in the oven. I’m going to try this recipe again but put it in the oven and bake it with my usual bread crumbs on the top and I think it’s going to be delicious!

    1. So glad to hear that you enjoyed the recipe!! I’m sure you could bake and top with bread crumbs and it would be fabulous! You’ll have to let us know how it turns out.

  35. 5 stars
    Literally THE best mac and cheese ever! My husband (whom will only eat Kraft!!!.. yes Kraft) LOOOOOOVED it. I only had 2 cups of cheddar so I added .5 of colby jack to it. I cooked mine for 2.5 hours and it was perfect!

    1. Oh that makes me SO happy to hear! I bet the Colby Jack was great in it. So glad your hubby was a fan, too. Thanks for sharing!!

    1. You can! It may take a bit longer to heat up in your crockpot since it will be more full. Depending on the size of your crockpot, you may need to do each batch in a separate crockpot.

    Absolutely loved this recipe. Delicious Mac n cheese. Definitely don’t cook it for more than 2 hours and don’t use shredded cheese.

  37. 5 stars
    So smooth, creamy & tasty! Another absolutely delicious recipe and the best homemade Mac & Cheese I have tried to date. I followed the recipe as is using sharp cheddar I grated/shredded myself, but also served it with fresh grated/shredded parmesan on top as mentioned in your add ins note. So many scrumptious possibilities for additional add ins, varying cheeses etc. and you noted some of my favs, lol, I will have to try some bacon or ham in it next time 😋
    From my family to yours, thanks so much for sharing your time & talents in the kitchen. Your recipes are always the best!

    1. Thank you so much for your kind words! They mean so much. I’m so glad that the recipe was a hit for your family. And yes, some of those add-ins and adaptations are a fun way to switch up the recipe. Thanks for giving the recipe a try!

  38. 5 stars
    This has been my favorite Mac & cheese recipe for several years now!! Everyone loves it, I’ve passed it onto more people than I could countNn

    I am going to attempt to make it with gluten-free pasta tomorrow night.. any suggestions? I don’t want the pasta to turn to mush, so I was thinking I’d probably only cook it halfway through.

    1. Yay!! I’m so glad you love the Mac and cheese. It’s a favorite here too, for sure. I imagine you have already made the dish with gluten-free pasta. I’d be curious to hear how it turned out/what you did? Yeah, I would suggest to keep an eye on those noodles so it doesn’t cook too long.

  39. 5 stars
    So I’ve made this many times. I usually prepare as directed, then dump into a casserole dish and top with butter breadcrumbs, then bake at 350° for 40 minutes or so. It’s perfect! Today, I’ve added shredded chicken and green onions. It smells amazing! I also usually add a pinch of ground mustard and a pinch of nutmeg, it really makes it pop.

  40. 5 stars
    This recipe is so easy and something I always have the ingredients in the house for. It makes a good amount and doesn’t take too long to throw together or to cook. Plus it’s super cheesy and yummy!
