# Ingredients:
→ Main
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 -
0.5 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 large skillet, heat olive oil over medium-low heat. Add sliced onions, season with kosher salt and black pepper, and cook for 20 to 25 minutes, stirring occasionally, until golden and soft. Set aside.
02 -
In a mixing bowl, combine ground beef, ketchup, Worcestershire sauce, onion powder, kosher salt, and black pepper. Gently mix and form into four patties slightly larger than the rye bread slices.
03 -
Heat 2 tablespoons unsalted butter in a cast-iron skillet over medium heat. Cook the patties for 4 to 5 minutes per side until browned and cooked through. Transfer to a plate and set aside.
04 -
Wipe the skillet clean and melt the remaining unsalted butter. Place 4 slices of rye bread on a work surface. Layer each with a cooked beef patty, caramelized onions, and 2 slices of Swiss cheese. Top each stack with another slice of rye bread.
05 -
Place assembled sandwiches in the skillet over medium heat. Grill for 2 to 4 minutes per side, pressing gently, until the bread is crisp and the cheese has melted.
# Notes:
01 -
Thinly slicing the onions ensures even caramelization and flavor.
02 -
Press sandwiches gently with a spatula while grilling to promote golden, crisp crusts.
