🍔 Ultimate Patty Melt with Secret Sauce 🧀

Bring the diner experience home with this classic patty melt, complete with a mouthwatering secret sauce. Perfect for a cozy family dinner or a satisfying lunch break!

🍽️ Ingredients 🍽️

- 4 tbsp butter, plus more for spreading
- 1 large onion, thinly sliced
- 8 slices of Swiss cheese
- 1 lb ground beef
- 8 slices of rye bread
- Salt and pepper to taste
- For the Secret Sauce:
  - 1/2 cup mayonnaise
  - 1 tbsp relish
  - 1/2 tsp garlic powder
  - 2 tbsp ketchup
  - 1 tsp Worcestershire sauce
  - 1/2 tsp onion powder
  - Salt and pepper to taste

🧑‍🍳 Directions 🧑‍🍳

1. Prepare the secret sauce by whisking together mayonnaise, ketchup, relish, Worcestershire sauce, garlic powder, and onion powder in a small bowl. Season with salt and pepper to taste and set aside.
2. In a skillet over medium heat, melt 1 tbsp of butter. Add onions, season with salt and pepper, and cook until caramelized, about 10-15 minutes. Transfer onions to a plate.
3. Shape the ground beef into 4 patties, slightly larger than the bread slices. Season with salt and pepper.
4. Using the same skillet, cook patties over medium heat to your preferred doneness, approximately 4 minutes per side for medium. Remove and set aside.
5. Spread butter on one side of each bread slice. To assemble, layer the non-buttered side of 4 bread slices with secret sauce, a slice of cheese, a beef patty, caramelized onions, another slice of cheese, and top with another bread slice, buttered side up.
6. Grill sandwiches in a clean skillet over medium heat until bread is golden and cheese has melted, about 3-4 minutes per side.
