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.
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.
Mustard is slightly acidic and spicy, which enhances the overall umami flavor of the mac and cheese. I promise, you won’t taste it!
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!
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!
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
How to Make Instant Pot Mac and Cheese Step by Step
Cook the Noodles: Add 16 ounces (1 box) of elbow macaroni, 4 cups of water, 1 teaspoon of kosher salt, ½ teaspoon of garlic powder, ½ teaspoon of onion powder, and ¼ teaspoon of dry mustard powder to the Instant Pot and stir. Attach the Instant Pot lid and ensure the valve is in the “sealing” position. Set the Instant Pot to Pressure Cook – Manual for 4 minutes.
Add the Cheese: Once the Instant Pot has finished cooking, release the pressure manually. Place a towel over the valve to avoid any splatters. Remove the lid and stir in 2 tablespoons of unsalted butter and 3½ cups of freshly shredded cheddar cheese.
Thicken the Sauce: Once the cheese is fully incorporated, stir in ¾ cup of heavy cream. The macaroni and cheese will thicken as it sits. If it becomes too thick, add more heavy cream to thin it out. Season to taste with salt and serve.
