  • Instant Pot


  • 1/3 lb ground pork sausage
  • 1 tbsp olive oil optional
  • 1/2 green bell pepper seeded and stem removed, chopped
  • 1/2 cup mushrooms sliced
  • 6 large eggs
  • 1/2 cup cream of mushroom
  • 1/2 cup milk
  • 1 cup cheddar cheese shredded, divided
  • 20 tater tots frozen


  • Set Instant Pot to saute. Add the sausage and cook until no longer pink. Add olive oil (only if pot is too dry) and add peppers and mushrooms and cook for an additional 2-3 minutes, or until softened. Pour contents into a strainer and allow grease to drain. Meanwhile, rinse out pot.
  • Return pot to pressure cooker and add 1 1/2 cups water to pot. Coat a round 6-inch pan with cooking spray. Pour the sausage mixture into the pan.
  • In a medium bowl, whisk the eggs, cream of mushroom soup, milk and 1/2 cup of the cheddar cheese. Pour the mixture over the sausage mixture in the pan.
  • Press the tater tots into the mixture, ensuring that they are fully immersed in liquid. Sprinkle the remaining 1/2 cup of cheese evenly over the top and cover pan tightly with foil. Place on trivet and lower into the Instant Pot.
  • Place the cover on the pot and set timer to 35 minutes on high pressure (pressure cook setting). It will take the IP around 8 minutes to build up pressure before it begins cooking.
  • When cooking is done, let the pressure release naturally for 5 minutes then do a quick release and allow the float valve to drop.
  • Carefully remove the pan from the pot by pulling up the trivet. Remove foil and let sit for 15 minutes before slicing and serving.


Replace the breakfast sausage with a leaner meat if desired, but the sausage adds incredible flavor to the dish!
Or replace the sausage with an equal amount of cooked, crumbled bacon!
Use red, orange or green bell pepper – pick your favorite!
Put out some sour cream and chopped green onions for a perfect condiment to compliment the meal.
Sprinkle salt and pepper over each helping of casserole just before serving!
Replace the tater tots with an equal amount of hash brown, if that is all you have on hand.
Substitute the mushrooms for an equal amount of your veggie of choice!
