By ragef.com Ingredients:
- Approximately forty-five minutes
- Output: four sandwiches
- One tablespoon of olive oil
- 2 cups of finely sliced onion from 1 big onion
- Six tablespoons of unsalted butter, divided
- Garlic powder and kosher salt
- 2 tablespoons of ketchup
- 1 and a half pounds of lean ground beef
- 2 teaspoons Worcestershire sauce
- 8 rye bread slices
- 1/2 teaspoon onion powder
- Roughly eight ounces of Swiss cheese, sliced
Instructions:
- Heat olive oil in a big pan over medium-low heat. Add the sliced onions and cook, stirring regularly, for 20 to 25 minutes until caramelized and very brown. Season with salt and pepper to taste.
- While the onions cook, heat a cast-iron skillet over medium-high heat. Melt 2 tablespoons of butter in the hot pan.
- In a large bowl, gently mix the ground beef, ketchup, Worcestershire sauce, 1/2 teaspoon onion powder, 1 teaspoon salt, and a pinch of pepper. Form the mixture into four equal patties, each slightly wider than the bread slices.
- Cook the patties in the hot pan for 4-5 minutes on each side until nicely browned. Remove from the skillet and set aside.
- Assemble the patty melts: Wipe out any excess grease from the pan and melt 2 more tablespoons of butter. Place four slices of rye bread in the pan, butter side down. Top each slice with a burger patty, Swiss cheese, half the caramelized onions, and another slice of cheese. Close the sandwiches with the remaining bread slices, butter side up.
- Cook each patty melt for 2-4 minutes per side, gently pressing down with a spatula until golden brown and the cheese is melted.
- Once done, remove the melts from the pan and cut them diagonally. Enjoy your delicious sandwiches!
