Slow Cooker Mac and Cheese is rich, smooth, creamy, and doesn’t get easier to make! Just add the noodles, milk, and cheese to the crock pot and let it do all the work.

I love that Slow Cooker Mac and Cheese can be served as a side or as the main course! We love to have it as a creamy side dish alongside mains like fried chicken thighs or baked chicken tenders.

Ingredients for Slow Cooker Mac and Cheese.

Ingredients

The key to this recipe is using the blend of cheese for a smooth and creamy sauce that is very rich and flavorful.

  • Elbow Macaroni – This is the classic noodle shape to use for macaroni and cheese!
  • Whole Milk – You want a high fat content for a creamier, richer cheese sauce.
  • Evaporated Milk – it has less water content to make a creamy sauce.
  • Cheese – Colby Jack, Mild Cheddar, Velveeta, and Cream Cheese all melt together really well. The Velveeta is a processed cheese, which I often shy away from, but when I want an ultra creamy sauce that will stay smooth, this is what I turn to.
  • Unsalted Butter – Always use unsalted so you can control the amount of saltiness in your finished dish.
  • Spices – Salt, Pepper for flavor and Ground Mustard for a slight tang. Do not use regular yellow mustard.

Recipe FAQs

Why is my mac and cheese mushy?

If you overcook the pasta (either on too high of heat or by cooking for too long), then it will get mushy. Also make sure to only boil the noodles until just al dente.

What is the best cheese to use in mac and cheese?

It’s best to use a blend of cheeses – using a mix of cheeses that melt well and become creamy as well as cheeses that add rich flavor. It’s best to buy blocks of cheese and shred it yourself. The pre-shredded cheese doesn’t melt as well.

How do you store leftovers?

Leftovers can be stored, covered, in the fridge for up to 5 days. Leftovers can also be frozen, once fully cooled, in airtight freezer containers for up to 3 months. It’s best to fully thaw before reheating. 

What’s the best way to reheat Mac and Cheese?

For best results, reheat on the stovetop over medium heat. If you choose to microwave, I like to add a little milk or cream and reheat at 50% power for 1-3 minutes. Keep in mind that reheating can overcook the pasta and cause it to become mushy.

Variations

  • Add Protein – You can add 1-2 cups of shredded chicken or it’s great topped with pulled pork.
  • Stovetop – While this particular recipe won’t translate to on the stove top, you can make my creamy stovetop shells and cheese instead!
  • Spices – You can add other spices such as paprika, onion powder, garlic powder, and even cayenne pepper if you like heat!

Pro Tips

  • Cook Noodles Until Al Dente – Cook the pasta 5-6 minutes or just until “al dente” so they don’t overcook in the crockpot. 
  • Evaporated Milk – Evaporated Milk is used because it has less water content and keeps the sauce nice and creamy. 
  • Different Cheeses – Velveeta helps keep the texture of the cheese sauce smooth while the addition of real cheese is better for flavor. 
  • Stir Every Hour – This is important so the cheese can melt into a sauce.

Notes

  • We use Evaporated Milk (this is the unsweetened milk in the can, not regular milk) because it has less water content and keeps the sauce nice and creamy. 
  • Velveeta helps keep the texture of the cheese sauce smooth while the addition of real cheese is better for flavor. 
  • Store leftovers in an airtight container in the fridge for up to 4-5 days or in the freezer for up to 3 months.
