Ingredients
  

1 lb ground beef

1 large onion, thinly sliced

2 tbsp butter

1 tbsp olive oil

4 slices Swiss cheese

4 slices rye bread

2 tbsp Worcestershire sauce

1 tsp garlic powder

Salt and pepper to taste

4 tbsp mayonnaise

Fresh parsley for garnish (optional)

Instructions
 

Caramelize the Onions: In a large skillet, melt butter and olive oil over medium heat. Add the sliced onions, a pinch of salt, and cook slowly, stirring occasionally, until they become golden brown and caramelized, about 20-25 minutes. Stir in Worcestershire sauce and garlic powder, cook for an additional 2 minutes, and then remove the onions from the heat.

    Prep the Patties: In a bowl, combine ground beef, salt, and pepper, mixing until just combined. Form into two equal-sized patties.

      Cook the Patties: In the same skillet used for the onions, sear the patties over medium-high heat for about 4-5 minutes on each side, or until they reach your desired doneness. In the last minute of cooking, place 2 slices of Swiss cheese on each patty, covering loosely with a lid to let the cheese melt.

        Assemble the Sandwich: Spread mayonnaise on one side of each rye bread slice. In the skillet, place two slices of rye bread, mayo side down, and top each with a cheeseburger patty. Add a generous scoop of caramelized onions on each patty. Top with the remaining slices of rye bread (mayo side up).

          Grill the Patty Melts: Allow the sandwich to grill for about 2-3 minutes on each side, pressing down gently with a spatula to ensure crispy, golden-brown results. Once both sides are grilled, remove from skillet.

            Serve: Cut each sandwich in half and garnish with fresh parsley if desired. Serve with a side of fries or a simple salad for a complete meal.
