  • 1 pound dried macaroni
  • 4 cups of water
  • 4 tablespoons of butter
  • 1/2 tablespoon of dijon mustard
  • 1 tablespoon of kosher salt
  • 2 dashes of Frank's Red Hot Sauce
  • 1 12 oz can of evaporated milk or 1.5 cups whole milk
  • 12 oz sharp cheddar cheese shredded
  • 4 oz mozzarella shredded


  1. In the stainless steel insert of the Instant Pot, combine dried pasta, water, butter, mustard, salt and hot sauce.
  2. Lock Instant Pot lid in place and close vent.
  3. Use manual mode to set Instant Pot to High Pressure for 4 minutes.
  4. Instant Pot will take 10-15 minutes to come to pressure, then it will count down from 4 minutes.
  5. Once Instant Pot finishes 4 minute countdown, immediately turn pressure release valve to venting (Quick Release) and turn Instant Pot completely off. IMPORTANT - if any liquid comes out of the pressure release valve use wooden utensil or pot holder to close the valve. Wait a minute and try to release pressure again. The keep warm mode should not be on to prevent overcooking the pasta.

  6. Once Instant Pot has released all the pressure, turn lid to open, keeping lid angled away from you to prevent steam burns.

  7. Stir in evaporated milk, followed by shredded cheese by the handful.
  8. Continue stirring until cheese in completely melted.
  9. Serve immediately, or switch warm setting back on to keep warm.

Recipe Notes

This recipe works best with store-bought shredded cheese. I've tested this recipe with both evaporated milk and whole milk and both work great! Evaporated milk has a richer flavor, but you can add extra cheese to thicken and enrich when using fresh milk.
