Instructions

• First, melt your butter in a large skillet over medium heat. Toss in those sliced onions and cook 'em slow till they’re soft and caramelized. Takes about 10 minutes, so you get a sweet, rich base. For more tips on caramelizing, check out pressure cooker meals.
• Next, add your mushrooms to the skillet. Season everything with salt, pepper, and garlic powder. Cook those mushrooms down till they’re tender, roughly 5-7 minutes. You’re building flavor here!
• In a separate bowl, mix your ground beef with Worcestershire sauce if you’re using it. Sprinkle a bit more salt, pepper, and garlic powder to taste. Get your hands in there and mix it up real good.
• Shape your beef into patties. Then cook them in the same skillet with the onions and mushrooms until browned and cooked through. About 6-7 minutes per side. This is where that pressure cooker prep really shines.
• Take the patties out and set ’em aside. Now in that skillet, lay down a slice of bread. Top it with a patty and sprinkle on the cheese. Cover it with another piece of bread.
• Grill the sandwich till it’s golden brown and the cheese melts, around 3-4 minutes per side. Keep an eye on it so you get that perfect crunch without burning.
• Repeat the sandwich making for all patties and bread slices you got. Make sure every bite’s tasty and melty and golden.
• Slice your patty melts in half, serve ‘em up warm, and get ready to enjoy every cheesy, juicy bite. For more sandwich ideas, see our pressure cooker meals.
