Ingredients

  • 2 cups uncooked elbow macaroni – Elbow macaroni noodles are a mac and cheese classic, but you can use other similarly sized noodles like shells, cavatappi, penne, farfalle, fusilli, or rotini.
  • 4 tablespoons butter – salted or unsalted butter both work for this recipe
  • 2ยฝ cups grated cheddar cheese – use any cheese that melts well, or add a flavor twist with manchego, muenster, provolone, Monterey jack, fontina, gruyere, or American cheese. Even Velveeta cheese works.
  • ยฝ cup sour cream – or plain Greek yogurt
  • 1 (10.75-ounce) can condensed cheddar cheese soup – or cream of chicken soup
  • ยฝ teaspoon salt
  • 1 cup whole milk – whole milk makes the creamiest sauce but a lower fat milk can be used.
  • black pepper, to taste – for added flavor, use garlic salt with parsley flakes

How to Make Crock Pot Mac and Cheese

  1. PASTA. Bring water to a boil and cook 2 cups of macaroni for only 6 minutes. Drain and set aside.
  2. SAUCE. In a medium pan, mix 4 tablespoons butter and 2ยฝ cups shredded cheese until cheese melts. Add ยฝ cup sour cream, 1 can condensed cheddar cheese soup, ยฝ teaspoon salt, 1 cup whole milk, and season with black pepper. Stir until combined. 
  3. SLOW COOK. Spray the crock pot with nonstick cooking spray. Add the cheese sauce to the slow cooker and the cooked macaroni. Mix until combined and cook on low for 2 hours stirring every once in a while.

Use at least a 6-quart crockpot for this recipe. To double this recipe, which we do all the time, we have been able to have everything fit in out 8-quart slow cooker.

    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 350ยฐ 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.

    1. Lil'Luna Team says:

      Thanks for sharing what you did!! Sounds delicious! Glad you enjoy the recipe. ๐Ÿ™‚

    This has been my favorite Mac & cheese recipe for several years now!! Everyone loves it, Iโ€™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 donโ€™t want the pasta to turn to mush, so I was thinking Iโ€™d probably only cook it halfway through.

    1. Lil'Luna Team says:

      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.

    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 ๐Ÿ˜‹
    From my family to yours, thanks so much for sharing your time & talents in the kitchen. Your recipes are always the best!

    1. Lil'Luna Team says:

      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!

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

    1. Lil'Luna Team says:

      Thank you!! So glad that you enjoyed the recipe!

  6. TracyEllison says:

    Hey there I’m looking to make this for a crowd of 20+ can you double this recipe
    Thank you

    1. Lil'Luna Team says:

      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.

  7. TracyEllison says:

    He6 there 8m looking to make this fir a crowd of 20+ can you double this recipe
    Thank you

    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. Lil'Luna Team says:

      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!!

    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. Lil'Luna Team says:

      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.
