Instant Pot Mac and Cheese takes just 4 minutes in the Instant Pot and you have perfectly creamy and cheesy homemade mac and cheese. It's comfort food in a bowl and thanks to the pressure cooker, it is so quick and easy to make.
Place macaroni, water, butter, dry mustard, garlic powder, pepper, and salt in the Instant Pot. Place lid on, make sure valve is in "sealing" position and set to "Manual" or Pressure Cook on "High" for 4 minutes.Do a quick pressure release.
Once the pin drops, remove lid and stir in 1/2 cup of milk. Add the cheese in 3 batches, stirring until each addtion is melted before adding the next.
Add more milk if needed.
Note: Cooking time does not include the time it takes for the Instant Pot to pressurize.
