A delightful twist on the classic patty melt, combining savory beef patties with caramelized onions and melted Swiss cheese, all grilled to perfection.
Combine the ground beef, milk, onion powder, salt, and black pepper in a mixing bowl.
Mix gently to avoid overworking the meat, which can make the patties tough.
Shape the mixture into four patties, roughly the size of the bread slices.
Make a small indentation in the center of each patty to prevent it from puffing up during cooking.
Heat a skillet over medium heat and cook the patties for 3-4 minutes on each side until browned.
Avoid pressing down on the patties while cooking to retain their juices.
In the same skillet, melt butter and sauté the onions until golden and caramelized.
Stir occasionally to prevent burning and ensure even cooking.
Butter one side of each bread slice. Place a slice, buttered side down, in the skillet.
Use softened butter for easy spreading.
Layer cheese, a cooked patty, caramelized onions, and more cheese on the bread. Top with another slice, buttered side up.
Press gently to help the sandwich hold together.
Grill the sandwich in the skillet until the bread is golden and the cheese is melted, about 3-4 minutes per side.
Cook on medium-low heat to ensure the cheese melts without burning the bread.
Serve the sandwiches warm with your favorite side dish.
Cut the sandwiches diagonally for a classic presentation.
