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.

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

      Mine do also! Thank you for sharing that!

    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)!

  6. Susan says:

    Can I get everything ready ahead of time and then just turn the crockpot on

    1. Kristyn Merkley says:

      You sure could ๐Ÿ™‚

        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!

      2. Lil'Luna Team says:

        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.

  7. Kimberly j Dixon says:

    Can you use 1% milk, 1/2 & 1/2 or heavy cream?

    1. Kristyn Merkley says:

      I’ve added 1% & it’s fine ๐Ÿ™‚ I haven’t tried the other two.

    I donโ€™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 !!

    1. Kristyn Merkley says:

      Awe, I am so glad you decided to try it & happier you liked it! Thank you so much for sharing that!

    2. Pam says:

      I am making this soon. How much extra cooked noodles did you end up adding?
      Thanks!

  9. Brandi Hagerman says:

    I cant find the soup what can i substitute for

    1. Kristyn Merkley says:

      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.

      1. ellen says:

        Cream of chicken, mushroom or celery work great!

    2. Christine says:

      I’ve used Condensed Cheddar Cheese Broccoli Soup

  10. Marissa says:

    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. Kristyn Merkley says:

      I use bagged & I have bought a block of cheddar & shredded it. I like to use fresh cheese for pastas, but both are great ๐Ÿ™‚
