Ingredients for Instant Pot Mac & Cheese

Pasta Elbow macaroni noodles are my first choice but you can use other small varieties of pasta.

Water and Seasonings – Season the cooking water in this recipe as it is absorbed by the pasta, adding great flavor. Do not drain the water; the starches from the pasta help thicken it and make a creamy sauce.

Cheese – Sharp cheddar and Parmesan cheese make a rich cheese sauce. You can replace some or all of the cheddar with gruyere, gouda, fontina, or even Monterey jack. Skip the mozzarella cheese in this recipe, as it isn’t bold enough.

Variations

  • Replace half of the cooking water with reduced sodium chicken broth & skip the salt.
  • Add seasonings like garlic powder, cayenne pepper or a dash of hot sauce.
  • For some extra nutrition, stir in vegetables like spinach or steamed broccoli.
  • Replace the milk with half and half or evaporated milk if desired.
  • Add rotisserie chicken, diced ham, or even ground beef or sprinkle with crisp bacon.

How to Make Instant Pot Mac and Cheese

Cook Time 6 minutes

Pressure Preheat 10 minutes

Total Time 26 minutes

Servings 8 servings

  • In a 6qt Instant Pot, add uncooked elbow noodles, water, butter, dry mustard, onion powder, seasoned salt, and pepper.

  • Add the lid and turn to seal. Select MANUAL – HIGH PRESSURE for 6 minutes.

  • Once completed, turn or press the valve to release any pressure (quick release). There will be cooking liquid in the Instant Pot – do not drain it.

  • Stir in the cream cheese until melted. Add ¼ cup milk slowly until blended.

  • Add the cheddar and parmesan cheeses and stir until melted, adding additional milk if needed to reach the desired consistency. You may not need all of the milk.

  • Serve immediately.

This recipe can be made with other types of cheese, ensure you use a bold or sharp cheese for the best flavor.
Shred the cheese yourself for the best results, pre-shredded cheeses have additives and they don’t always melt well.
Other shapes of pasta can be used, but depending on the shape, cooking time may need to be adjusted slightly.
You may not use all of the milk; add just a little bit at a time.
6 minutes on high should be just right for most brands of pasta, if you use another small shape and find it isn’t cooked through, put the lid back on and let it rest for a few minutes.
