Instant Pot Philly Cheesesteak Stuffed Peppers Recipe

Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function. Add oil butter mushrooms and onion. Saute for 5 minutes; add garlic and saute about 30 seconds more. Transfer mixture to a bowl.

Add sirloin Italian seasoning garlic salt and black pepper to the pot. Saute until browned about 5 minutes. Stir sirloin mixture into the bowl with the mushroom mixture.

Wash out the pressure cooker insert. Add about 1/2 cup water to the pressure cooker and place a steamer rack inside.

Place 1 slice of provolone cheese in the bottom of each pepper half. Top with sirloin-mushroom mixture and cover each with aluminum foil. Place stuffed peppers on the rack inside the pressure cooker.

Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 25 minutes. Allow 10 to 15 minutes for pressure to build.

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

Release pressure carefully using the quick-release method according to manufacturer's instructions about 5 minutes. Unlock and remove the lid. Transfer peppers to a rimmed baking sheet and remove aluminum foil. Top each pepper with another slice of provolone cheese.

Broil peppers under the preheated broiler until lightly golden 1 to 3 minutes.
