Patty Melt Hamburger Recipe

Prepare the Onions

Slice the onion into thin rings. In a skillet, melt 1 tablespoon of butter over medium heat, add the sliced onions, and sprinkle with a little salt. Sauté until the onions are soft and caramelized, about 10-15 minutes. Stir occasionally to prevent burning.

Form the Patties

While the onions are cooking, shape the ground beef into two equal-sized patties. Season each side of the patties with salt and black pepper.

Cook the Patties

In another skillet, heat the remaining tablespoon of butter over medium-high heat. Add the patties and cook for about 3-4 minutes on each side or until they reach your desired level of doneness. During the last minute of cooking, place a slice of Swiss cheese on each patty to melt.

Assemble the Patty Melt

On one slice of rye bread, place a patty with melted Swiss cheese on top, followed by a generous amount of caramelized onions. Top with another slice of rye bread. Repeat for the second sandwich.

Grill the Sandwiches

In the same skillet used for the patties, grill the assembled sandwiches over medium heat until the bread is golden brown and crispy, about 2-3 minutes per side.

Serve

Remove from the skillet, slice in half if desired, and serve hot.
