Ingredients
- 1 lb ground beef
- 1 small onion, thinly sliced
- 4 slices of your favorite melty cheese (like Swiss, American, or cheddar)
- 4 slices of rye or sourdough bread
- 2 tablespoons butter
- Salt & pepper, to taste
- Optional: Thousand Island or mayo-mustard sauce for spreading
Instructions
- Caramelize the onions:
In a skillet over medium heat, melt 1 tablespoon of butter. Add sliced onions and cook until golden and soft, about 10-15 minutes. Set aside. - Form & cook the patties:
Shape ground beef into thin, wide patties slightly larger than your bread slices. Season both sides with salt and pepper. In the same skillet, cook patties over medium-high heat until browned and cooked through, about 3–4 minutes per side. Set aside. - Build your melt:
On one slice of bread, layer cheese, beef patty, caramelized onions, another slice of cheese, then top with the second slice of bread. Spread butter on the outside of each slice. - Grill it up:
In a clean skillet or griddle, grill the sandwich over medium heat until golden brown and the cheese is melted, flipping once—about 3 minutes per side. - Serve & devour:
Slice in half and serve hot with pickles or crispy fries on the side!
