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.

    Can you double this recipe?

    1. Lil'Luna Team says:

      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!

  2. Linda Elliott says:

    I made this for Easter and it was a hit!

    1. LilLunaTeam says:

      I’m so glad everyone liked it!

  4. DeAnna says:

    What size crock pot if I double the recipe? Anxious to make for my family for Easter!

    1. LilLunaTeam says:

      I would use a 10 quart crockpot if you double this recipe. I hope you have a fabulous Easter!

  5. DeAnna says:

    If I double the recipe, what size crockpot should I use? I’m anxious to make for Easter!

    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. LilLunaTeam says:

      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!

  7. Cris says:

    What size crockpot did you use for this amount? Have you ever doubled the recipe? Iโ€™m wondering if I can make a bigger batch for a crowd. ๐Ÿ˜Š

    1. LilLunaTeam says:

      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!

    I use a little extra butter & cheese and itโ€™s to die for! So easy & good!

    1. Kristyn Merkley says:

      Can’t go wrong with that! Thank you!

    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!

    1. Kristyn Merkley says:

      That all sounds great! Thank you for sharing what you did!
