Grilled Cheese Patty Melts (Print Version)

# Ingredients:

→ Patty

01 - 1 lb ground beef
02 - 1 teaspoon Worcestershire sauce
03 - 1 teaspoon garlic powder
04 - 1 teaspoon onion powder
05 - Salt and black pepper, to taste
06 - 1 tablespoon olive oil or butter, for cooking

→ Sandwich

07 - 8 slices rye, sourdough, or thick-cut white bread
08 - 1 medium onion, thinly sliced
09 - 2 tablespoons butter, for caramelizing onions
10 - 4 tablespoons unsalted butter, for grilling bread
11 - 8 slices cheddar cheese
12 - 4 slices Swiss cheese

# Instructions:

01 - In a large bowl, combine ground beef, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix gently to combine without overworking the meat. Divide the mixture into 4 equal portions and shape into thin, wide patties slightly larger than your bread slices. Heat olive oil in a skillet over medium heat and cook patties for 3-4 minutes per side or until fully cooked. Remove from the skillet and set aside.
02 - In the same skillet, add 2 tablespoons of butter. Once melted, add the sliced onions and cook on medium-low heat for 10-12 minutes, stirring occasionally, until golden and caramelized.
03 - Spread butter on one side of each bread slice. On the unbuttered side of four bread slices, layer 1 slice of cheddar cheese, a cooked beef patty, a scoop of caramelized onions, 1 slice of Swiss cheese, and another slice of cheddar cheese. Top with another slice of bread, buttered side facing out.
04 - Wipe out the skillet and heat over medium heat. Place the assembled sandwiches in the skillet and cook for 3-4 minutes per side until the bread is golden brown and crispy, and the cheese is melted. Press lightly with a spatula for even toasting. Work in batches if needed, keeping finished sandwiches warm in a 200°F oven.
05 - Slice each sandwich in half and serve immediately with your favorite dipping sauce or side of fries.

# Notes:

01 - Feel free to substitute cheeses with melty options like provolone, American, or Gouda.
02 - For extra flavor, add a splash of balsamic vinegar or a pinch of sugar when caramelizing onions.
03 - Patties and onions can be prepared in advance and reheated when assembling the sandwiches.
