This Sausage Egg Casserole is an easy, make ahead breakfast that can be cooked in the oven or instant pot! It's healthy, hearty and reheats perfectly for busy weekdays!
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.
Oven
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.
