Servings: 6


  • 1 pound uncooked pasta
  • 4 cups water
  • 2 Tablespoons butter
  • 1 teaspoon salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon mustard powder
  • black pepper (to taste)
  • 8 ounces shredded cheddar cheese (we prefer extra sharp)
  • 2 Tablespoons cream cheese (cut into cubes)
  • 1/4 cup grated Pecorino Romano or Parmesan cheese
  • 1/2 - 1 cup milk


  • Add pasta, water, butter, salt, garlic powder, mustard powder, and black pepper to the bowl of your Instant Pot. Stir briefly and gently to combine.
  • Cover and set the lid to “Sealing.”  Cook on Manual high pressure for 4 minutes, followed by a quick release of the pressure (cover the vent with a dishtowel or cloth when releasing to prevent splatter). Once it's finished, carefully remove the lid.
  • Add in the cheeses and gently stir until they are fully melted.
  • Add the milk, starting with 1/2 cup (and working up to as much as 1 cup total, as needed) and stir until everything is combined and the sauce is creamy (if your sauce seems thin, let everything sit for a few minutes until it thickens up).
  • Add freshly cracked black pepper and serve!
