Ingredients

  • 16 ounces uncooked white or whole wheat elbow pasta
  • 4 cups water
  • ½ teaspoon salt or to taste
  • ¼ teaspoon pepper or to taste
  • ¼ teaspoon paprika
  • teaspoon garlic powder
  • 2 tablespoons unsalted butter
  • 8 ounces sharp white cheddar cheese about 2 cups shredded
  • 4 ounces sharp cheddar cheese about 1 cup shredded
  • ½ cup milk warmed, whole milk is best

Instructions

  • Place pasta, water, salt, pepper, paprika and garlic powder in Instant Pot. Stir well. Even out the pasta to make sure it is all in the liquid.
  • Close the Instant Pot lid and move the steam release valve to the sealing position. Cook on Manual/Pressure Cook at high pressure for 3 minutes for whole wheat elbow pasta or 4 minutes for white elbow pasta. (A good rule of thumb is to cook pasta in the Instant Pot for half of the cook time listed on the box.)
  • While the pasta cooks, shred the cheese and warm the milk.
  • As soon as the cook time ends, quick release the pressure by moving the steam release valve to the venting position. If possible, do a slow and careful quick release by moving the valve a little bit at a time, to slow the release of starchy steam from the pasta and minimize mess.
  • Once all of the steam has been released and the pin drops down, open the Instant Pot lid and add the butter to the pot. Slowly stir in the cheese, a little bit at a time, followed by the milk. Taste and add more salt and pepper as desired.
  • If the mac and cheese seems too liquidy, let it sit on the warm setting for a few minutes and it will thicken up. Serve.

Notes

  • Cheese: I recommend buying a block of cheese and shredding it yourself, rather than using pre-shredded cheese. Pre-shredded cheese is often coated with an anti-caking agent to keep it from clumping together and it doesn't melt as well.
  • Other pasta shapes: You can use this easy formula to figure out how long you need to cook your pasta in the Instant Pot, no matter which shape of pasta you use:  take the package cook time and divide it in half. That's it! If you like your pasta al dente (firmer), subtract one more minute from the pressure cooking time.
  • Leftovers: Store in an airtight container in the refrigerator for up to 3 days. I recommend stirring in a little bit of milk when reheating mac and cheese. Warm it gently in a pot on the stove, stirring often, or in the microwave.
Recipe Variations:
  • Add Protein: Stir in Instant Pot Shredded Chicken, chopped Poached Chicken, rotisserie chicken, cubed cooked ham, cooked sausage, or crumbled bacon.
  • Add Veggies: After cooking, mix in cooked broccoli, frozen peas, Roasted Butternut Squash, or fresh spinach.
  • Add Spice: Add a pinch of cayenne pepper or a dash of hot sauce.
  • Try Other Cheeses: Try using a combination of sharp cheddar and either mozzarella, Gruyere or Monterey jack. You can also stir in some grated Parmesan cheese for extra flavor.
