to add After Cooking

  • 1 can evaporated milk 12 fluid ounces
  • 1 cup parmesan
  • 4 ounces cream cheese ½ an 8-ounce box
  • 1 teaspoon ground mustard
  • 3 cups extra sharp white cheddar freshly shredded


  • Add the chicken stock, pasta, salt, garlic powder, and butter to the Instant Pot.
  • Cook for 2-Minutes: Close the Instant Pot, adjust the pressure release valve to 'Sealing' and set the pot to cook on 'Manual' or 'Pressure Cook', 'High Pressure' for 2 minutes. To avoid a mess when releasing the pressure, you can use my Flip-The-Trivet for Mess-Free Pasta Method.
  • Shred Cheese: While the pasta cooks, shred the white cheddar.
  • 2-Minute NPR: Once the cooking time has finished, allow for a 2 minute NPR (natural pressure release) and then release any remaining pressure. After the pressure has been released and the pin has dropped, open the pot. Leave on 'Keep Warm'.
  • Add Remaining Ingredients: Add the evaporated milk, parmesan cheese, cream cheese, ground mustard, and white cheddar to the pasta and mix until the cream cheese and cheddar have fully melted.
  • Allow to sit on 'Keep Warm' to thicken for up to 10 minutes or until the pasta has reached your desired consistency.
  • Serve and enjoy!
