Ingredients

Here is all that you will need:

  • elbow macaroni – Elbow macaroni noodles are a Mac and Cheese classic, but you can use other similarly sized noodles like shell, cavatappi, penne, farfalle, fusilli, or rotini.
  • butter – salted or unsalted butter both work for this recipe
  • grated cheddar cheese – Other shredded cheese that melt well, or add a twist of flavor, include manchego, muenster, provolone, monterey jack, fontina, gruyere, or american cheese. Even Velveeta cheese works.
  • sour cream
  • condensed cheddar cheese soup
  • salt and black pepper – For added flavor, use garlic salt with parsley flakes
  • whole milk – Or at least 2% milk

HOW to make it

Three easy steps:

  1. PASTA. Bring water to a boil and cook macaroni for 6 minutes. Drain and set aside.
  2. SAUCE. In a medium pan, mix butter and cheese until cheese melts. Add sour cream, soup, salt, milk and pepper until combined. 
  3. SLOW COOK. Add the cheese sauce to the slow cooker (spray with nonstick cooking spray first) along with the cooked macaroni. Mix until combined and cook on low for 2 hours stirring every once in awhile.

TIPS and TRICKS

Here are some advanced tips to take it to the next level…

Thicken the sauce. The sauce should be creamy, not soupy. To thicken your Mac and Cheese, use a few methods:

  • remove the lid of the crock pot to allow for liquid to evaporate
  • add in more cheese
  • cornstarch slurry: in a separate bowl, combine 1 tablespoon of COLD water with 1 tablespoon of cornstarch. Stir it into the Mac and Cheese and the dish will thicken as it continues to cook. Repeat if needed.

Add-ins. When there are about 30 minutes left in the cooking time, add in some of these suggestions:

  • cooked bacon bits, diced cooked ham, grilled chicken, or cooked hamburger
  • parmesan cheese
  • broccoli or roasted red peppers
  • garlic powder, dry mustard, onion powder, red pepper flakes, or paprika.

Making it last

Here are need-to-know tips to store it…

STORE. Store leftovers in an airtight container in the refrigerator for 3-5 days.

REHEAT. The key is to reheat slowly on low heat. Adding in a bit more milk can help smooth out the texture. You can reheat in the slow cooker, covered in the oven, stovetop, or microwave.

FREEZE. This pasta dish can be frozen for 2-3 months. When you’re ready to use, thaw it in the fridge and reheat slowly over low heat.

    Made for a family gather. Turned out great. Everyone loved it. I used an immersion blender to smooth out all the ingredients. Was super smooth. Will be making again.

    1. Lil'Luna Team says:

  3. Debbie Page says:

    Can you make this a day or two ahead of time and just bake it when you’re ready?

    HELLO !! I made the mac-n-cheese for Thanksgiving dinner. It was my side for the kids. Well, the adults loved loved loved it ALSO. Amazing thing is I haven’t made mac-n-cheese for 30 years & that came from a box 🙂 I didn’t have a very good grater so that took me longer ! I used the small elbow noodles from Trader Joe’s. I believe what ever size or style pasta used would be DEEEEELISH 😋 TY Steve

    1. Lil'Luna Team says:

      Oh I’m so happy to hear that the mac and cheese was a hit!!

    I made this for a family function and the family loved it❣️❣️
    They’ve asked me to make it again for another family gathering.
    I think this will be the item I’ll be required to bring from now on! 😉

    1. Julie says:

      What can I use to substitute the cheddar soup? Couldn’t find it!

      1. Lil'Luna Team says:

        You could use another condensed soup that you enjoy. Cream of chicken perhaps.

    Did a huge batch (x10 the recipe) for a graduation party of 100 people. Cooked it in a large roasting pan and it was a hit! I cut the salt in half since condensed soup mix is ultra salty and I’m glad I did….it probably could’ve gone without any salt added at all. This is much easy and holds up better with a better texture than making a traditional cheese base using a roux. Melting the cheese slowly is key to a smooth texture and slowly add milk to not chill the cheese sauce down too much. Look forward to making again in a normal batch size. That was a lot of cheese to shred!

    Do you have any other options for the cream of cheddar soup?

    1. Lil'Luna Team says:

      You could do a different condensed soup… like cream of chicken. It would alter the flavor of the Mac and cheese alittle but should still taste yummy. You’ll have to let us know how you like it if you try it with a substitute soup.

  10. Sally Cook says:

    I was wondering with your crock pot Mac and cheese, can I put macaroni in the crock pot uncooked? I’ve tried a recipe that you could and it came out amazing. Your recipe sounds even better, I just don’t wan to cook macaroni ahead of time. It seems to take the most time.
