This is the Best Slow Cooker Mac and Cheese, made with two kinds of cheese and seasoned to perfection. Thanks to a few secret ingredients, this mac and cheese comes out perfectly cooked and super creamy every single time.

The Best Slow Cooker Mac and Cheese

I’ve found that sometimes, even when you follow a homemade mac and cheese recipe to a T, it can come out a little grainy or separated. There are so many variables—how long you cook the roux, how high the heat is when you add the cheese, how quickly you add the milk.

That is why I absolutely love this super simple slow cooker mac and cheese recipe. It relies on three ingredients to help stabilize the sauce: cream cheese, evaporated milk, and Dijon mustard. They work together to make sure you get a perfectly creamy emulsified cheese sauce that is still just as rich and flavorful as stovetop macaroni.

Follow along to find out a bit more about these magic ingredients, and get ready to add this recipe to your regular dinner rotation.

Why You’ll Love This Recipe

  • It’s foolproof! Thanks to a few secret ingredients, this recipe won’t break on you. 
  • Couldn’t be easier. Let the slow cooker do most of the work! You don’t even need to make a roux for this recipe.
  • A family favorite. Who doesn’t love mac and cheese? This recipe is basically guaranteed to be a hit every single time.

Key Ingredients

  • Pasta – elbow macaroni is the traditional mac and cheese pasta shape, and the one I most often use. Another great option to use with the slow cooker is cavatappi. It’s a little bit sturdier and so you run less of a risk of overcooking the pasta. 
  • Cream Cheese – cream cheese works wonders as a binder in slow cooker mac and cheese, making sure it doesn’t break or become gritty. 
  • Evaporated Milk – similar to the cream cheese, evaporated milk helps create a super stable sauce during a long cooking period. Because evaporated milk also has a far lower water content, you don’t need to make a roux for the sauce to be super creamy.
  • Dijon Mustard – adding Dijon mustard to mac and cheese helps to balance out the flavor, but it also serves as yet another emulsifier for the cheese sauce. 
  • Nutmeg – this is a classic flavor to add to mac and cheese because just a little bit will help enhance the flavors and balance out all of that richness. 
  • Milk – adding whole milk in addition to evaporated milk helps keep the flavor on point.
  • Sharp Cheddar Cheese – sharp cheddar cheese is my favorite for mac and cheese, but really any cheddar will work. Or, use a combination of other cheeses like gouda, havarti, and Monterey jack. No matter what kind of cheese you use, just be sure to shred your own from a block rather than buying the pre-shredded cheese from a bag. Pre-shredded cheese will never melt properly.

How to Make Mac and Cheese in a Slow Cooker

  1. Add the ingredients. Add all ingredients besides the cheddar cheese to a lightly sprayed slow cooker and mix. Sprinkle 3 cups of shredded cheddar cheese over the top, stirring evenly, then cover and cook on low.
  2. Stir. After 1 hour of cooking, stir well.

Frequently Asked Questions

How do you reheat mac and cheese?

To reheat mac and cheese, you want to add a little bit of milk or cream to the pasta and reheat gently either over the stove, in the microwave, or even in the crockpot.

How can you keep the cheese sauce from breaking?

This recipe has a few secret ingredients that help to keep the cheese sauce from breaking—especially during such a long cooking time. The cream cheese, evaporated milk, and Dijon mustard all work together to stabilize the sauce and keep it extra creamy.

Can you substitute whole milk for evaporated milk?

You can substitute milk for evaporated milk at a rate of 1:1, however the sauce will be much less creamy. Evaporated milk has quite a bit less water content than milk, so it means that there is no need for a roux to thicken the sauce.

Recipe Tips

  • Check before the suggested “done” time. Remember that all slow cookers are different and some cook quite a bit more quickly or slowly than others. Because of this, I recommend checking periodically even before the suggested cooking time.
  • Shred your own cheese! You can’t use pre-shredded cheese for this recipe. It has anticaking agents in it that prevents it from melting well in sauces.
  • Don’t forget to spray the inside of your crock pot. You will thank yourself for this later.

Storage Instructions

  • Refrigerator: store in an airtight container in the fridge for up to 1 week.
  • Freezer: it is possible to freeze this, although we recommend you make it fresh since it is so simple and tastes so much better that way!  If you choose to freeze, ensure it is completely cool before transferring to an airtight container and freezing for up to 2 months.
  • Reheating: to reheat, transfer the mac and cheese to a pot and add a splash of milk.  Warm over medium-low, mixing to be sure it doesn’t burn.  Taste and add a touch more seasoning, milk or a bit more shredded cheese if it needs.
