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.

    1. Kristyn Merkley says:

      Agreed…goes with anything!! Thank you for making this recipe ๐Ÿ™‚

  2. Beth says:

    I’m looking to make this for my daughter party and wondering about doubling it. How well does it do?

    1. Kristyn Merkley says:

      Great!! They would love it!

  3. Karenina says:

    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! ?โ€โ™€

    1. Kristyn Merkley says:

      I have not cooked them in the crock pot by themselves. I usually boil them in the pot first ๐Ÿ™‚ Sure hope you like them!! Happy Thanksgiving!

    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.

    1. Kristyn Merkley says:

      Thank you so much for sharing all that! I am glad you tried it & liked it!

  5. Katie Darkow says:

    WHAT IF I DON’T HAVE CREAM OF CHEDDAR SOUP? CAN I USE ANY CREAM SOUP? i DON’T WANT TO GO TO THE STORE TODAY:)

    1. Kristyn Merkley says:

      You know, I have not tried, but I am sure you could ๐Ÿ™‚ Let me know what you use & if you like it!

  6. STACEY says:

    if you double the recipe do you have to double the cook time as well?

    1. Kristyn Merkley says:

      No, you shouldn’t have to ๐Ÿ™‚

      1. Judy says:

        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

      2. Kristyn Merkley says:

        Hmm, that’s a good question. Maybe, it wasn’t stirred enough?

  7. mICHELLE says:

    HELLO – CAN I DOUBLE THIS RECIPE?

    1. Kristyn Merkley says:

      You sure could ๐Ÿ™‚ Enjoy!!

  8. Erin says:

    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. Kristyn Merkley says:

      It shouldn’t clump in this recipe ๐Ÿ™‚ It’s one of our favorites!

    1. Kristyn Merkley says:

      I sure hope they like it!! I love that!

      1. Kelsey says:

        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!!

      2. Lil'Luna Team says:

        I think that would work just fine! You can certainly give it a try!

  10. Amber says:

    Can you double this recipe? want to make it for easter and we have 10 people coming over!

    1. Kristyn Merkley says:

      Yes, of course ๐Ÿ™‚ Hope it’s a hit!
