Patty Melt with Secret Sauce

The Patty Melt is an American diner classic — a juicy beef patty layered with melted cheese and caramelized onions, sandwiched between buttery grilled bread. What makes this version special is the homemade secret sauce, a creamy, tangy spread that ties all the flavors together.

This easy recipe delivers the perfect balance of savory, sweet, and cheesy goodness — ideal for lunch, dinner, or weekend comfort food.

Ingredients
For the Patty Melts:

1 lb (450 g) ground beef (80/20 blend for juiciness)

1 medium onion, thinly sliced

8 slices of rye bread (or sourdough)

8 slices Swiss or American cheese

2 tablespoons butter, softened

Salt and pepper to taste

For the Secret Sauce:

½ cup mayonnaise

2 tablespoons ketchup

1 tablespoon yellow mustard

1 teaspoon Worcestershire sauce

1 tablespoon finely chopped pickles (or relish)

½ teaspoon garlic powder

½ teaspoon smoked paprika (optional)

Instructions:
1. Make the Secret Sauce

In a small bowl, mix mayonnaise, ketchup, mustard, Worcestershire sauce, pickles, garlic powder, and paprika until smooth.
Taste and adjust seasoning. Refrigerate while you prepare the burgers.

2. Caramelize the Onions

Heat a skillet over medium heat.

Add a drizzle of oil or a small pat of butter, then add the sliced onions.

Cook slowly for 10–12 minutes, stirring often, until the onions are soft and golden brown.

Remove from heat and set aside.

3. Form and Cook the Patties

Divide the ground beef into 4 equal portions and shape into thin patties about the same size as your bread slices.

Season both sides with salt and pepper.

Cook in a skillet over medium-high heat for about 3–4 minutes per side, until browned and cooked through.

Place a slice of cheese on top of each patty to melt slightly.

4. Assemble the Patty Melts

Spread secret sauce on one side of each bread slice.

On four slices, layer a patty, some caramelized onions, and another slice of cheese.

Top with the remaining bread slices, sauce side down.

5. Grill the Sandwiches

Butter the outsides of each sandwich.

Heat a large skillet or griddle over medium heat.

Grill each sandwich for 2–3 minutes per side, pressing gently, until golden brown and crispy.

Slice in half and serve immediately.

Tips and Variations

Try gruyère or cheddar cheese for a twist in flavor.

Swap rye bread for Texas toast or sourdough for extra crunch.

Add a few pickled jalapeños or crispy bacon for a bold upgrade.

Serve with fries, coleslaw, or sweet potato chips for a full diner-style meal.
