Believe it or not, making box mac & cheese is even easier in the Instant Pot! No need to drain or babysit the pasta while it cooks and everything simply mixes together in one pot.



  • 1 box Mac & cheese
  • pinch of kosher salt
  • 1 tbsp butter
  • 1/2 cup whole milk


  1. Combine the dry pasta, pinch of kosher salt, and 1 cup plus 2 tablespoons of water in the Instant Pot. Place on the lid, turn the valve to sealing, and set the cook time for 3 minutes on high pressure.
  2. When the cook time is complete, quick release the pressure. Add the butter and stir, breaking up the pasta. Sprinkle on the cheese packet, stir, then pour in the milk. Continue stirring, incorporating the cheese mixture into the noodles.
  3. Turn the Instant Pot on to Sauté and cook the macaroni for 2-3 minutes until the cheese fully incorporates and the sauce thickens slightly.


You can easily double this recipe and use two boxes of pasta. Double the ingredients, but keep the cook times the same.
