Pin it A classic diner favorite featuring juicy beef patties, caramelized onions, and gooey melted cheese sandwiched between crispy, buttery rye bread&all cooked to perfection in a cast-iron skillet.
I first served this to my family and they loved the rich flavors and crispy texture it offers every time.
Ingredients
- For the Onions: 2 large yellow onions, thinly sliced 2 tablespoons unsalted butter 1 tablespoon olive oil 1/2 teaspoon kosher salt 1/4 teaspoon freshly ground black pepper
- For the Patties: 1 lb (450 g) ground beef (80/20 blend preferred) 1 teaspoon Worcestershire sauce 1/2 teaspoon garlic powder 1/2 teaspoon kosher salt 1/4 teaspoon freshly ground black pepper
- For Assembly: 8 slices rye bread 8 slices Swiss cheese 4 tablespoons unsalted butter, softened
Instructions
- Caramelize the onions:
- In a large cast-iron skillet over medium heat, melt 2 tablespoons butter with olive oil. Add sliced onions, season with salt and pepper, and cook, stirring occasionally, until deep golden brown and softened, about 20 minutes. Transfer onions to a bowl and wipe skillet clean.
- Prepare the patties:
- In a bowl, gently mix ground beef with Worcestershire sauce, garlic powder, salt, and pepper. Form into 4 thin, oval patties roughly the size of your bread slices.
- Cook the patties:
- Heat the cleaned skillet over medium-high heat. Add patties and cook 2–3 minutes per side until well browned and just cooked through. Remove from skillet and set aside.
- Assemble the sandwiches:
- Butter one side of each slice of rye bread. Place 4 slices, buttered side down, on a cutting board. Top each with 1 slice of Swiss cheese, a beef patty, a generous spoonful of caramelized onions, another slice of Swiss cheese, and finish with a second slice of bread, buttered side up.
- Grill the melts:
- Return skillet to medium heat. Place sandwiches in the skillet (in batches if needed), pressing gently. Cook 3–4 minutes per side, until bread is golden brown and cheese is melted. Add more butter to the skillet if necessary.
- Serve immediately:
- Cut in halves or quarters.

Notes
For extra flavor, try adding a dollop of Dijon mustard or a few slices of pickled jalapeños before grilling. Swap Swiss cheese for cheddar or provolone if desired. Serve with classic diner sides like potato chips, fries, or a simple salad. Rye bread can be substituted with sourdough for a different twist.
