4 cheese Instant Pot Mac and Cheese made extra creamy with Boursin. This easy mac and cheese recipe is ready in under 20 minutes.

My kids LOVE macaroni and cheese. And they come by it honestly. A creamy mac and cheese is one of my favorite side dishes, too!

If you’ve tried our unique mac and cheese with cottage cheese and liked it, you’ll love this less than 20 minute Instant Pot macaroni and cheese with Boursin. It is loaded with 4 cheeses and the garlic and herb Boursin cheese make the flavor unforgettable!

What Sets our Instant Pot Mac And Cheese Apart

Our Instant Pot mac and cheese is made extra special with the addition of 4 cheeses: sharp cheddar, colby jack cheese, mozzarella cheese. Each cheese carries a different flavor, so when you combine cheeses, you get a really full bodied flavor.

The extra special cheese is the Boursin garlic and fine herb cheese. It melts so silky smooth, adding creaminess mac and cheese sauce.

Instead of pre-shredded cheeses, buy blocks of cheese and shred it at home.
I like using Barilla Protein+ pasta for added protein.

Add the milk and Boursin. Stir until combined.
Slowly add the shredded cheese in ½ cup increments, gently stirring until cheese is melted and mixed well. Don’t add all the cheese at once or it may clump.

Recipe Substitutions

Evaporated Milk. We normally use 2% milk in this recipe, but we all have cans of evaported milk in the pantry that need used up. It’s a great substitution if you are short on milk!
Heavy Cream. I know you have heavy cream on hand from making our cinnamon rolls and chocolate chip cookies. Use heavy cream in place of milk for even more creaminess.
Gluten-Free Pasta. To make a gluten free version of this macaroni and cheese, you can easily swap out regular pasta for gluten free pasta. One of our favorite gluten free pastas is Banza pasta made with chickpeas. It is high in protein and fiber.
Cheeses. Don’t have the cheese we have listed? Use a different kind of cheese or your own cheese blend. Try Gouda, Monterey Jack, Gruyere or Fontina. Try swapping the Boursin for cream cheese, but it will have a little less flavor.

What can you add to mac and cheese?

This is a great base recipe for macaroni and cheese. You can stir in other add-ins to add protein, veggies or additional flavor:

Meats. Ground beef for a hamburger macaroni, leftover turkey or ham, rotisserie chicken, shredded pork or bacon.
Veggies. Caramelized onions, broccoli, peas or red pepper.
Sundried tomatoes.
Jalapeños or a dash of hot sauce for a spicy kick of heat.

What to Serve with Instant Pot Mac and Cheese

We love instant pot mac and cheese with homemade meatloaf, fried chicken and especially shredded pork. In fact, we combine pork and macaroni in our pulled pork mac and cheese.

Reheating Instructions

If you have individual servings of leftover mac and cheese, it’s easy to reheat them in the microwave.

If you have a large amount of mac and cheese leftovers to reheat, place it in an oven safe dish and cover with foil. Bake in a 350º oven for 25 minutes or until it is heated through. The exact time will depend on if the casserole is frozen and how much of it there is.

Freezer Instructions

Yes! Because mac and cheese is a pasta dish, it freezes well. You can freeze it in individual containers and it makes great school or work lunches.

Freeze in an airtight container for up to 3 months.
