  • 8 eggs
  • 1/2 cup milk
  • 3/4 teaspoon salt
  • 1/2 teaspoon parsley
  • 1/8 teaspoon pepper
  • 3/4 cup frozen hashbrowns
  • 6 turkey breakfast sausages cooked and sliced
  • 1 green onion sliced
  • 1/2 cup shredded cheddar cheese divided
  • 1.5 cups water


  • In a large bowl or glass measuring cup, whisk together eggs, milk, salt, parsley and pepper.
  • Lightly grease a 1.7L glass baking dish (Instant Pot) or round pie plate (oven). Layer hashbrowns, sausages, green onion, and 1/4 cup cheese in the baking dish.
  • Pour eggs over top. Sprinkle with remaining 1/4 cup cheese.

Instant Pot

  • Pour 1.5 cups water into Instant Pot. Cover baking dish with foil and place on the trivet in the Instant Pot. 
  • Put the lid on, turn to sealing, and select Manual or Pressure Cook for 35 minutes. It will take about 10 minutes to come to pressure.
  • When the cook time is up, let pressure release naturally for 8-10 minutes, then open the valve and remove the lid. Remove the baking dish from the pressure cooker and serve.


  • Preheat oven to 350 degrees F. 
  • Bake for 35-45 minutes (cook time will vary depending on the size of your dish and the depth of the ingredients), until eggs are set right through the center. Serve.
