How to Make Macaroni and Cheese in an Instant Pot

This Pressure Cooker Mac and Cheese recipe will work in any brand of electric pressure cooker, including the Instant Pot, Ninja Foodi, or Power Pressure Cooker XL.

💨 This is a fantastic dump and go Instant Pot recipe!

First, if you’re a bacon fan, crisp up a bit of crumbled bacon. Reserve the cooked bacon while you finish the mac and cheese and use it as a tasty and crunchy garnish.

(No need to discard the bacon fat on the bottom—it’ll add flavor to the finished dish!) 

Also: don’t be afraid of the dry mustard and cayenne! This is NOT a spicy recipe, and it’s 100% kid-approved. These spices add a subtle, but delicious, flavor to the macaroni and cheese.

What Pasta to Use

Stick with elbows or small shells for best results. They’re small, with enough surface area to absorb all of the liquid. A larger pasta shape, even penne, might not absorb the water as well. We usually use classic elbow macaroni for this cheesy dish.   

💡 You can use whole wheat or a gluten-free pasta in this recipe, but you may need to change your cook time.

I recommend using half the cook time on the box minus 1 minute. (See my post on How to Cook Pasta in the Instant Pot for complete details.)

If you find that the pasta is not fully cooked after a quick pressure release, simply keep the sauce simmering using the Sauté function until you have al dente macaroni.

Make a Creamy Instant Pot Mac and Cheese Sauce without Flour or Butter

The secret to rich and creamy macaroni and cheese sauce without having to build a bechamel on the stove?

A can of evaporated milk. 

After pressure cooking, select Saute and add the evaporated milk and stir for 1 to 2 minutes in order to heat through. Be sure to wait for the sauce to warm fully before you turn off the pressure cooker and add cheese. 

🧀 When you add the cheese, there should still be a fair amount of milk in the bottom of the pot. This is OK! The pasta will continue to absorb the liquid while you add the cheese and will thicken as the dish cools. 

Add the shredded cheddar and Monterey Jack cheeses by the handful, stirring to melt them in before adding more. (If you add the cheese all at once, it won’t melt smoothly and might clump together.)

We love the two different kinds of cheese in this Instant Pot mac and cheese recipe. Sharp cheddar brings a nice edge to this classic dish. And Monterey Jack adds a hint of warming spice. Together, the result is a silky, creamy cheese sauce that’s packed with flavor.

Doubling & Halving This Pressure Cooker Mac and Cheese Recipe

Double Batch: If you change the amount of pasta, aim for an equal amount of pasta and water by volume.

Don’t add more than 6 or 7 cups of liquid, however, to stay below the maximum fill line on your pressure cooker pot. You want the macaroni to be fully submerged before sealing the pressure cooker, but still under the max fill line. 

More liquid also means the pressure cooker will take longer to reach full pressure, so reduce the cook time by a minute. If the pasta isn’t cooked to your liking, simply Saute until it reaches your preferred texture, as discussed above.

Half Batch: Halving this recipe is more straightforward. Simply cut all ingredients by half. No need to make changes to the cook time or procedure.

Can I Add Mix-Ins and Flavorings?

Absolutely! Think of this Instant Pot macaroni and cheese recipe as a blank (but delicious) canvas. Yes, it’s creamy and satisfying on its own. And we love it topped with crispy, crumbly bacon.

But the possibilities for dressing up this easy meal are endless!

Here are some of my readers’ favorite ways to flavor Pressure Cooker Mac and Cheese:

  • Browned sausage
  • Shredded chicken
  • Steamed broccoli
  • A pinch of smoked paprika for smokiness 
  • A dash of nutmeg and roasted Butternut squash for a warm, fall flavor
  • Fresh herbs like thyme, sage, oregano
  • Nuts like toasted walnuts or pumpkin seeds

Instant Pot / Pressure Cooker Mac and Cheese

Instant Pot / Pressure Cooker Mac and Cheese

Creamy, fast, and easy, this Instant Pot / Pressure Cooker Mac and Cheese is one of the best Instant Pot weeknight dinners, and it’s 100% kid and grown-up approved!

Prep Time 2 minutes
Cook Time 5 minutes
Additional Time 15 minutes
Total Time 22 minutes

Ingredients

  • ½ cup diced bacon*
  • 1 package (16-ounces) elbow macaroni or shells
  • 4 cups water
  • 2 teaspoons salt
  • 2 teaspoons dry mustard
  • ⅛ teaspoon cayenne pepper
  • 2 (12-ounce) cans evaporated milk
  • 2 cups sharp cheddar cheese, shredded
  • 2 cups Monterey Jack cheese, shredded
  • Salt and pepper, to taste

Instructions

  1. Select Sauté and add the bacon to the pressure cooking pot. Cook, stirring frequently, for about 5 minutes, until crisp. Transfer to a paper-towel lined plate, leaving the bacon fat in the pot. 
  2. Add the pasta, water, salt, mustard, and cayenne to the pressure cooking pot. Lock the lid in place, select High Pressure and 5 minutes cook time.
  3. When the cook time ends, turn off the pressure cooker and use a quick pressure release. When the valve drops, carefully remove the lid.
  4. Stir in the evaporated milk. (It will look like too much liquid, but it will thicken as it simmers.) Select Sauté on the pressure cooker and simmer until sauce is warm, thickened and pasta is tender, 1 to 3 minutes.
  5. Turn off the pressure cooker. Add both cheeses, a handful at a time, stirring between each addition, until the cheese melts and sauce is smooth. (It’s important to add the cheese a handful at a time so it doesn't clump together.)**
  6. Season with additional salt and pepper to taste.

Notes

*The bacon is optional—if you don't have it, just skip the first step and continue with the recipe.

**After adding the cheese, stir to check the sauce. It should be just slightly thinner than you like. It thickens as it cools, so by the time you dish it up, get everyone to the table, and sit down to eat, it will be the perfect thickness.
