For the Secret Sauce:
- 1/2 cup mayonnaise – The creamy base for the sauce.

Step-by-Step Instructions for Making Patty Melts with Secret Sauce
1. Prepare the Secret Sauce
Start by making the secret sauce. In a small bowl, combine mayonnaise, ketchup, sweet pickle relish, and Worcestershire sauce. Mix well until all ingredients are thoroughly incorporated. This sauce will bring the perfect balance of sweet, tangy, and creamy, taking your patty melt from good to extraordinary!
2. Caramelize the Onions
In a large skillet, melt 1 tablespoon of butter over medium heat. Add the thinly sliced onions and cook them, stirring occasionally, until they are beautifully caramelized. This process takes about 15-20 minutes but is totally worth it for the rich, sweet flavor of the onions that will complement the savory beef. Once the onions are golden brown and tender, remove them from the skillet and set them aside.
3. Shape and Cook the Beef Patties
Divide the ground beef into 4 equal portions and shape each portion into a thin patty. Season both sides with salt and pepper to taste. In the same skillet, cook the patties over medium-high heat for about 3-4 minutes per side, or until they are cooked through. The key here is to not overcook them – you want your beef patties to remain juicy and tender. Once the patties are cooked, remove them from the skillet and set them aside.
4. Assemble the Patty Melts
Now comes the fun part – assembling the sandwiches! Butter one side of each slice of rye bread. Place 4 slices of bread, butter-side down, on a clean skillet or griddle over medium heat.
- Layering:
- Start with a slice of Swiss cheese on the bread.
- Add a cooked patty on top of the cheese.
- Add a generous spoonful of the caramelized onions over the beef.
- Place a slice of cheddar cheese on top of the onions.
- Finally, top with another slice of bread, butter-side up.
5. Grill the Patty Melts
Cook the sandwiches until the bread is golden brown and the cheese has melted, about 2-3 minutes per side. You may need to press down on the sandwich gently with a spatula to help everything meld together. Keep an eye on it so that the bread doesn’t burn before the cheese is fully melted.
6. Slice and Serve
Once your patty melts are golden and the cheese is gooey, remove them from the skillet. Let the sandwiches rest for a minute before slicing them in half. Serve them warm with the secret sauce on the side or drizzled over the top.

Tips for Perfect Patty Melts
- Use high-quality beef: The beef is the star of this dish, so make sure to choose ground beef that’s flavorful and juicy. For a better taste, try using a mix of ground chuck and ground sirloin.
- Caramelize onions slowly: Don’t rush the caramelizing process. Slow cooking onions over low heat brings out their natural sweetness and flavor.
- Toast the bread perfectly: The bread should be golden brown and crispy. If you want extra crispiness, you can spread a thin layer of garlic butter on the outside of the bread before grilling.
- Secret sauce variations: Feel free to tweak the secret sauce to your liking! Add a pinch of cayenne pepper for a spicy kick, or mix in a teaspoon of Dijon mustard for an extra layer of flavor.
Serving Suggestions
While a patty melt is a meal in itself, you can serve it alongside some delicious sides to create a more complete meal:
- Fries: Classic crispy French fries or sweet potato fries are a great side to enjoy with a patty melt.
- Pickles: Pickles provide a nice contrast to the richness of the sandwich.
- Coleslaw: A tangy and crunchy slaw is a great way to balance out the flavors of the melt.
- Soup: Pair it with a bowl of tomato soup for a comforting combination that’s perfect for chilly days.
