Ingredients:

For the Secret Sauce:

1/2 cup mayonnaise

2 tablespoons ketchup

1 tablespoon sweet pickle relish

1 teaspoon Worcestershire sauce

1/2 teaspoon garlic powder

Salt and pepper to taste

For the Patty Melts:

1 pound ground beef (80/20 blend recommended)

Salt and pepper to taste

1 large onion, thinly sliced

8 slices of rye bread

Butter, softened

8 slices of Swiss cheese

Secret sauce (from above)

Instructions:

1. Make the Secret Sauce:

In a small bowl, mix together the mayonnaise, ketchup, sweet pickle relish, Worcestershire sauce, garlic powder, salt, and pepper. Set aside.

2. Prepare the Patty Melts:

Divide the ground beef into 4 equal portions and shape them into patties. Season both sides of the patties with salt and pepper.

Heat a skillet over medium-high heat. Cook the patties for about 3-4 minutes per side, or until they reach your desired level of doneness. Remove from the skillet and set aside.

In the same skillet, add a little oil if needed and cook the sliced onions until they are caramelized and golden brown, about 10-15 minutes. Remove from the skillet and set aside.

Butter one side of each slice of rye bread.

Assemble the sandwiches by placing a slice of Swiss cheese on the unbuttered side of 4 slices of rye bread. Top each with a cooked beef patty, caramelized onions, and a dollop of secret sauce. Then add another slice of Swiss cheese and finally top with the remaining slices of rye bread, buttered side facing out.

3. Cook the Patty Melts:

Heat a skillet or griddle over medium heat. Place the assembled sandwiches on the skillet and cook for about 3-4 minutes on each side, or until the bread is golden brown and the cheese is melted.

Once cooked, remove the patty melts from the skillet and let them rest for a minute before serving.

4. Serve:

Slice the patty melts in half and serve hot with extra secret sauce on the side for dipping. Enjoy!
