🛒 Ingredients
For the Patty Melts
1½ lbs lean ground beef
2 tsp Worcestershire sauce
1 tsp salt
½ tsp black pepper
12 slices marble rye bread
3 slices cheddar cheese
3 slices Swiss cheese
3 Vidalia onions, thinly sliced
8 tbsp unsalted butter
½ cup secret sauce (see below)
For the Secret Sauce
¼ cup mayonnaise
¼ cup Dijon mustard
1 tbsp barbecue sauce
½ tsp hot sauce
👨🍳 Instructions
1. Make the Secret Sauce
In a small bowl, stir together:
Mayonnaise
Dijon mustard
Barbecue sauce
Hot sauce
Set aside.
2. Prepare the Burger Patties
In a large bowl, mix:
Ground beef
Worcestershire sauce
Salt and pepper
Form into 6 oval-shaped patties, roughly the size of your bread slices.
3. Caramelize the Onions
In a skillet, melt 2 tbsp of butter over medium heat.
Add onions and cook for 15–20 minutes, stirring occasionally until soft and golden brown. Set aside.
4. Cook the Patties
In another skillet, cook patties over medium-high heat for about 2–3 minutes per side, just until browned and cooked through. Remove and set aside.
5. Assemble the Sandwiches
Wipe skillet clean and prepare to grill the sandwiches:
Butter the outer sides of each bread slice.
Place buttered side down in the pan.
Spread 1 tbsp of secret sauce on each slice.
Add about 3 tbsp of caramelized onions, a slice of cheddar or Swiss, 1 burger patty, another slice of cheese, and top with more onions, sauce, and the second slice of bread (butter side up).
6. Grill the Sandwiches
Cook sandwiches in a skillet or on a griddle over medium heat until golden brown on both sides and cheese is melted, about 3–4 minutes per side. Press down gently with a spatula while cooking.
7. Serve & Enjoy
Slice in half and serve hot. Add a side of fries, chips, or a pickle spear for the full diner experience!
📝 Notes
Use sweet onions like Vidalia for the best caramelization.
Swiss and cheddar together provide the perfect melt and tang combo.
Rye bread holds up beautifully on the griddle and adds a unique bite.
Pressing the sandwich helps melt the cheese and crisp the bread evenly.

Q: Can I make it vegetarian?
A: Try a plant-based patty and vegan cheese. The sauce can easily be made dairy-free.
