Ingredients
Serves 4
For the Patty Melts:
- 1 lb ground beef
- 1 large onion, thinly sliced
- 8 slices rye bread
- 4 slices Swiss cheese
- 4 slices cheddar cheese
- Butter, for grilling
- Salt and pepper, to taste
For the Secret Sauce:
- ½ cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon sweet pickle relish
- 1 teaspoon Worcestershire sauce
How to Make Patty Melts with Secret Sauce
1. Make the Secret Sauce
In a small bowl, stir together the mayonnaise, ketchup, relish, and Worcestershire sauce. Set aside in the fridge while you prepare the rest.
2. Caramelize the Onions
In a skillet over medium heat, melt 1 tablespoon of butter. Add the sliced onions and cook slowly, stirring occasionally, until golden and caramelized—about 15–20 minutes. Transfer to a bowl.
3. Shape and Cook the Patties
Divide the ground beef into 4 equal portions and form thin patties slightly larger than your bread slices (they’ll shrink while cooking). Season both sides with salt and pepper.
In the same skillet, cook the patties over medium-high heat for about 3–4 minutes per side, or until fully cooked. Set aside.
4. Assemble the Patty Melts
Butter one side of each slice of rye bread. On the unbuttered side, layer a slice of Swiss cheese, a cooked patty, caramelized onions, a slice of cheddar cheese, and top with another slice of bread (butter-side facing out).
5. Grill to Perfection
Place the assembled sandwiches in a skillet or on a griddle over medium heat. Cook each side for 2–3 minutes or until golden brown and the cheese is melted. Press gently with a spatula for that crispy edge.
6. Serve and Enjoy
Let rest for a minute before slicing in half. Serve warm with a side of secret sauce for dipping or drizzle it right on top.
Serving Suggestions
Patty melts are rich and hearty, so they go great with:

Tips & Variations
- Lighter option: Use ground turkey or chicken instead of beef.

- Make-ahead tip: Caramelize onions in advance and store in the fridge for quick meals later.
