How Do You Make Mac and Cheese in a Crockpot?

It’s so much easier than you think to make this 3 ingredient mac and cheese slow cooker recipe. Just add all of the ingredients (in the correct order), give it a stir, and let the appliance do its magic! Once the noodles are cooked through, it’s ready to serve.

Plus, this easy crock pot mac and cheese uses a no boil method! I have found that pouring boiling water over my noodle mixture then stirring it well really helps to make sure the elbow macaroni cooks evenly.

Will Dry Pasta Cook in a Slow Cooker?

Absolutely! The only trick is making sure you have the right liquid to pasta ratio so the pasta doesn’t burn or stick to the bottom. Thicker pasta noodles like this elbow macaroni also hold up a little better to the slow cooker than thinner pasta.

What is the Best Cheese for Slow Cooker Mac and Cheese?

The best cheese is always the cheese you love! But cheddar is definitely the cheese for traditional mac and cheese flavor. Cheese blends work great as well and can be used to create a milder flavor — or just use up what you have in your refrigerator. Just be sure it melts easily to get a creamy sauce.

You will find using cream cheese really helps make this 3 cheese mac and cheese slow cooker recipe extra creamy. You can also substitute Velveeta cubes for ultra creamy crock pot mac and cheese.

How to Make the Creamiest Mac and Cheese Ever?

There are a couple of ways to make this easy crock pot mac and cheese extra creamy. 

  • Use heavy cream if you prefer a recipe without evaporated milk. 
  • Don’t skip the cream cheese in the 3 cheese mac and cheese slow cooker recipe! It really adds the creamiest texture to your pasta.
  • Substitute Velveeta cubes for some or all of your shredded cheddar cheese. It still has a great cheesy flavor but is made for melting.
