BEST PATTY MELT RECIPE RECIPES

Steps:

• Season ground beef with salt and pepper and divide into 3 equal-sized balls. Shape each ball as close as possible to the shape of the bread. Make an indentation in the center of each patty with your thumb.
• Melt butter in a skillet over medium heat and cook onion until soft and translucent, 5 to 8 minutes. Remove from the skillet and divide into 3 equal portions. Place beef patties into the same skillet and cook until desired doneness, 3 to 5 minutes per side.
• Meanwhile, spread 1 teaspoons mayonnaise on one side of each slice of bread.
• Place bread mayonnaise side-down in the skillet. Top with 1 slice of cheese, 1 beef patty, 1/3 of the onions, a second slice of cheese, and another slice of bread, mayonnaise side up. Cook bread until golden brown and cheese has started to melt, 3 to 4 minutes. Flip each sandwich over and cook an additional 3 to 4 minutes.

Steps:

• Heat 2 tablespoons of the oil in a medium skillet over medium. Add onion and ½ teaspoon of the salt. Cook, stirring often, until golden brown and soft, about 20 minutes. Set aside.
• Meanwhile, divide ground beef into 4 portions. Press each into a flat, ¼-inch-thick patty. Sprinkle with pepper and remaining 1 teaspoon salt.
• Heat remaining 2 tablespoons oil in a large cast-iron skillet over medium-high. Cook 2 patties at a time, pressing gently, until browned but still pink in the center, 2 minutes per side. Transfer to a plate.
• Stir together mayonnaise, mustard, barbecue sauce, and ketchup in a small bowl until combined.
• Wipe out cast-iron skillet; reduce heat to medium. Divide Cheddar among 4 of the bread slices; top each with a patty, caramelized onions, Swiss cheese slice, mayonnaise mixture, and remaining bread. Melt 2 tablespoons of the butter in skillet. Place 2 sandwiches in hot butter; cook (with another skillet on top of sandwiches to weigh them down) until golden brown and cheeses are melted, about 3 minutes per side. Repeat with remaining 2 tablespoons butter and 2 sandwiches.
