  • ½ tsp Onion Powder
  • 4 cup Chicken Broth or Water
  • 5 oz Evaporated Milk
  • 1 ½ cup Cheddar Cheese Shredded
  • 1 cup Frozen Peas

  • Remove 1 cup peas from freezer so that they can begin to thaw.

  • Give everything a quick stir.
  • Place lid on Instant Pot, turn vent to sealed position, press MANUAL and set the time for 3 minutes. It will take the pot a few minutes to come to pressure.
  • When the 3 minutes is finished, do a quick release.
  • Once the pin has dropped, carefully open Instant Pot.
  • Stir in a 5 oz can of evaporated milk, 1 ½ cup shredded cheddar cheese and 1 cup peas.
  • Let the pasta sit until the cheese is melted and the peas are warmed through.
  • Stir in 2 Tbsp fresh lemon juice.
  • Garnish with chopped parsley and serve immediately.


Be sure not to add more than 12 oz of pasta to the pot.  Too much pasta can cause the casserole to be dry.
