Ingredients You’ll Need for Patty Melts with Secret Sauce

0.5 tablespoon butter
1 large yellow onion, sliced thin
0.5 cup mayonnaise
2 tablespoons ketchup
1 tablespoon yellow mustard
2 tablespoons sweet pickle relish
1 teaspoon Worcestershire sauce
1 pound ground beef (80/20 blend)
0.5 teaspoon salt
0.5 teaspoon black pepper
8 slices rye or sourdough bread
4 tablespoons butter, softened
4 slices Swiss cheese
4 slices American cheese

Steps to Prepare Patty Melts with Secret Sauce

In a skillet, melt 0.5 tablespoon of butter over medium-low heat. Add the sliced onion and caramelize for about 20-25 minutes, stirring occasionally, until the onions turn golden brown.
In a small bowl, combine mayonnaise, ketchup, mustard, sweet pickle relish, and Worcestershire sauce to create the secret sauce. Mix well and chill until you’re ready to use it.
Shape the ground beef into 4 thin oval patties, making them slightly larger than your bread slices. Season both sides of the patties with salt and pepper.
In a hot skillet, cook the beef patties for 3-4 minutes on each side or until fully cooked. Once done, transfer them to a plate.
Butter one side of each slice of bread. On the unbuttered side, spread a generous amount of the secret sauce, followed by a slice of Swiss cheese, a beef patty, caramelized onions, a slice of American cheese, and then top with another slice of bread, buttered side facing out.
In a clean skillet over medium heat, grill the sandwiches for about 3-4 minutes on each side until the bread is golden brown and the cheese is nicely melted.
Serve hot, and feel free to offer extra secret sauce on the side for dipping!
