Ingredients
Scale
- 1 stick butter, divided
- 1 whole large onion, halved and sliced
- 1 1/2 lbs. ground beef
- salt and pepper, to taste
- 5 dashes Worcestershire sauce
- 8 slices Swiss cheese
- 8 slices rye bread
Instructions
- In a medium skillet, melt 2 tablespoons of butter over medium-low heat. Add the sliced onions and cook slowly for 20 to 25 minutes, stirring occasionally, until golden brown and soft.
- In a medium bowl, mix together the ground beef, salt & pepper, and Worcestershire sauce. Form into 4 patties. Melt 2 tablespoons butter in a separate skillet over medium heat. Cook the patties on both sides until totally done in the middle.
- Assemble each patty melt: slice of rye bread, slice of Swiss cheese, hamburger patty, 1/4 of the cooked onions, another slice of Swiss cheese, and another slice of rye bread. On a clean griddle or skillet, melt 2 tablespoons butter and grill the sandwiches over medium heat until golden brown. Add the remaining 2 tablespoons butter, flip the sandwiches, and cook the other side until golden brown, crisp, and cheese is melted.
Notes
For extra crispiness, press the sandwiches with a spatula while grilling. Use thinly sliced onions for faster caramelization. Serve immediately for the best melty texture.
