How to Store and Reheat 

Store leftover Instant Pot mac and cheese in an airtight container in the refrigerator for up to 4 days. Reheat in the Instant Pot using the “keep warm” function and stirring every few minutes or in 30-second increments until warmed through. Add a splash of cream to rehydrate the noodles.

How to Freeze 

Freeze Instant Pot mac and cheese in an airtight container or Ziplock bag for up to 3 months. Let thaw overnight in the refrigerator before reheating.

Serving Suggestions

This quick and easy pressure cooker mac and cheese is the perfect side to serve with chicken nuggets, air fryer hamburgers, grilled hot dogs, or mini turkey meatloaves. Add a side of corn on the cob, air fryer broccoli, or Buffalo cauliflower wings for a complete meal.

What melting cheeses are best for mac and cheese?

Sharp cheddar cheese will give you the most classic Mac and cheese flavor! But you can use 3½ cups of your favorite smooth melting cheese. Think cheddar, fontina, Colby, Swiss, Monterey jack, and provolone.

Why put mustard in mac and cheese?

Mustard is slightly acidic and spicy, which enhances the overall umami flavor of the mac and cheese. I promise, you won’t taste it!

Is it better to cook mac and cheese in milk or water?

I prefer to use a mixture of water and heavy cream in the Instant Pot. You could also cook it in milk, but I find this hack works just as well!

Why is my cheese not sticking to my macaroni?

If you used pre-shredded bagged cheese, it may not stick well to the pasta because of the starches added to prevent the cheese from clumping in the bag. I always recommend shredding your own cheese for this recipe!

How do you keep macaroni and cheese warm in an Instant Pot?

Use the “keep warm” function on your Instant Pot and stir the mac and cheese every so often to keep it warm for up to 10 hours.

5-Star Review

“This was soooo easy and yummy! I used fresh chicken stock instead of water and used 2 1/4 cheddar and 4 oz. of velveeta. When done I put in a backing dish, added bacon crumbles and put it in the oven for 10 minutes on 350 to crisp it up a bit. Delicious!” -Cathy
