How to Make Mushroom Swiss Patty Melt
- Prepare the Patties: In a bowl, combine ground beef with garlic powder, onion powder, salt, and pepper. Form into 4 evenly sized patties and set aside.
- Sauté the Mushrooms: In a large skillet, heat butter and olive oil over medium heat. Add sliced onions and sauté until soft and translucent. Stir in garlic and mushrooms along with thyme, seasoning with salt and pepper. Cook until the mushrooms are tender and any moisture has evaporated, about 5–7 minutes.
- Cook the Patties: In the same or a separate skillet, cook the beef patties over medium-high heat for about 4–5 minutes per side, or until desired doneness is reached.
- Assemble the Patty Melt: Spread mayonnaise and Dijon mustard (if using) on one side of each bread slice. On 4 slices, layer a cooked patty, a generous spoonful of sautéed mushrooms, and top with a slice of Swiss cheese. Place another slice of bread on top, mayonnaise side down.
- Grill the Sandwich: Heat a skillet or griddle over medium heat and melt a thin layer of butter. Place the assembled patties in the pan and grill each side for 3–4 minutes until the bread is golden and crispy and the cheese has melted.
- Serve: Slice the patty melts in half and serve warm with your favorite side salad or fries.

Storage for Mushroom Swiss Patty Melt
