01 - 1 tablespoon olive oil
02 - 2 cups thinly sliced onions
03 - 6 tablespoons unsalted butter, divided
04 - 1.5 pounds lean ground beef
05 - 1 tablespoon ketchup
06 - Worcestershire sauce, to taste
07 - 1/2 teaspoon onion powder
08 - Kosher salt, to taste
09 - Black pepper, to taste
10 - 8 slices rye bread
11 - 8 ounces Swiss cheese, sliced

# Steps:

01 - In a skillet, heat olive oil over medium-low heat. Add onions, season with salt and pepper, and cook for 20–25 minutes until golden and soft. Set aside.
02 - In a bowl, mix ground beef, ketchup, Worcestershire sauce, onion powder, salt, and pepper. Form into 4 patties slightly larger than the bread slices.
03 - In a cast-iron skillet, melt 2 tablespoons butter over medium heat. Cook patties for 4–5 minutes per side until browned. Remove and set aside.
04 - Wipe the skillet clean and melt the remaining butter. On 4 slices of rye bread, layer one patty, caramelized onions, 2 slices of Swiss cheese, and top with another slice of bread.
05 - Grill sandwiches in the skillet over medium heat for 2–4 minutes per side, pressing gently, until the bread is crisp and the cheese is melted.
