Just a Few Minutes to Prep

It finally feels like fall, which means it’s time to break out the Instant Pot and make some comfort food! This macaroni and cheese is a favorite of ours. Why? Because it only takes a few minutes to prep, EVERYTHING is done in the Instant Pot, and it tastes absolutely amazing.

This recipe is for all of the moms out there. It’s doable… on a weeknight. You can serve it on the side of just about anything. I’d suggest these Instant Pot BBQ chicken sliders, Crispy Cornflake Chicken Tenders, or these Homemade Honey Corn Dogs. It’s so good you’ll want to eat bowl after bowl of it too! Kid and parent approved. 

Don’t let the ingredient list intimidate you. It’s mostly spices. I think good macaroni and cheese requires more than just noodles, butter, milk and cheese. It needs flavor! I’ve amped up the flavor by replacing part of the water with chicken broth and adding seasonings like dried mustard, garlic, paprika and a hint of cayenne. Nothing detectable (this is not spicy mac and cheese)!

Best Noodles + Seasonings

Now as far as the noodles go I stuck with the classic elbows. However, any short noodle will do. I’m also a fan of mini shells or gemelli (twists). My kids also loved shaped noodles (but they usually need about a minute less in the Instant Pot due to their delicate nature).

And for seasonings, you want to make sure you have the following to make them extra flavorful:

  • coarse kosher sea salt
  • dried mustard
  • garlic powder
  • black pepper
  • paprika
  • cayenne pepper

And don’t forget the cheese – we use grated Colby jack cheese, grated Havarti cheese (mozzarella works too) and grated Parmesan cheese.

How to Make IP Mac and Cheese

To make the Instant Pot macaroni and cheese, you’ll add the pasta (a full pound) to the pot, along with broth, water, seasonings, and butter.

The macaroni takes 5 minutes on high pressure to cook. THAT’S IT!

While the pasta is cooking you can grate the cheese and measure out the milk.

Let the pressure release manually. Do not let it release naturally. Simply switch the valve as soon as the Instant Pot beeps and let it come down. It takes about 5 minutes.

The Instant Pot should be on the “KEEP WARM” setting. Pour in the milk and sprinkle in the cheese as you stir. Keep stirring until all the cheese has melted, then let the macaroni sit for 5 minutes. This will allow it to thicken.

Storing, Tips + Sides

If you are looking to change up this recipe, feel free to use your favorite cheeses or add-ins (like hot fogs, tuna, or veggies). We like it simple but there are so many ways to change this up.

To STORE the mac and cheese, just place in an air-tight container and place in the fridge for up to 4 days. To REHEAT, do that in the microwave or in the skillet. You may need to add a little more milk, broth or water if it’s too thick.
