Ingredient Checklist


Instructions Checklist
  • Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function. Heat oil in the pot and add mushrooms, onion, and garlic. Saute until mushrooms are tender and onions are translucent, about 5 minutes. Push Cancel. Transfer the mushroom mixture to a paper towel-lined plate and set aside. Clean the inside of the pot when it is cool enough to handle.

  • Whisk eggs and heavy cream together in a medium bowl. Stir in spinach, Parmesan cheese, salt, pepper, and garlic powder until well blended. Add the mushroom mixture and stir until well combined.

  • Pour 1 cup water into the pot and place a steamer rack trivet in the bottom.

  • Spray a souffle dish or other heat-proof dish with nonstick cooking spray. Pour egg mixture into the prepared dish and cover loosely with foil. Place the dish on top of the trivet.

  • Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 30 minutes. Allow 6 to 7 minutes for pressure to build.

  • Release pressure using the natural-release method according to manufacturer's instructions, for 10 minutes. Release remaining pressure carefully using the quick-release method, about 5 minutes. Unlock and remove the lid. Remove foil from the frittata and pour off any excess liquid before slicing and serving.
