Instant Pot Mac and Cheese

Instant Pot mac and cheese could not be easier, creamier, or more delicious. Our version incorporates the classic flavors of homemade macaroni and cheese with a combination of aged gruyere, sharp cheddar, and parmigiano cheeses, plus dashes of Dijon mustard, nutmeg and cayenne.

Ingredients

  • 1 pound (454 grams) elbow macaroni
  • 4 cups low-sodium vegetable broth or chicken broth
  • 1 small shallot minced
  • 1 teaspoon Dijon mustard
  • teaspoon ground nutmeg
  • teaspoon ground cayenne
  • ½ teaspoon fine sea salt
  • ¼ teaspoon freshly ground black pepper
  • ½ cup (120 ml) whole milk
  • 6 ounces (170 grams) Gruyère cheese (about 2 ½ cups shredded)
  • 6 ounces (170 grams) extra-sharp cheddar cheese (about 2 ½ cups shredded)
  • 2 ounces (60 grams) Parmigiano Reggiano cheese (about ½ cup grated)
  • ½ cup (60 grams) sour cream

Instructions

  • Place macaroni, broth, shallot, mustard, nutmeg, cayenne, salt, and pepper into Instant Pot and stir.
  • Set vent to sealing position. Cook on manual mode, high pressure, for 4 minutes. (Pot will take about 10 minutes to come up to pressure before timed cooking begins.)
  • Carefully do a manual pressure release by turning the vent to open. (We like to use a towel or a long-handled spoon to do this.)
  • Stir in milk and cheeses until cheese is melted.
  • Stir in sour cream.
  • Serve hot.

Notes

  1. IP mac and cheese is quick, easy, and best shortly after it's made — so I don't typically make it in advance.
  2. That said, leftovers are good, too. They'll keep well in an airtight container in the fridge for a week. Reheat in the microwave. You can stir a spoonful of sour cream into each reheated serving to reignite the creaminess if you like.
  3. For a more budget-friendly (and equally delicious) option, replace the gruyere with six ounces more cheddar, or four ounces more cheddar plus two ounces of a good-quality American cheese.
