There’s something timeless about a patty melt. It’s the perfect blend of a juicy beef patty, gooey melted cheese, and crisp, buttery bread. My first one didn’t come from a trendy restaurant—it came from a small roadside diner. The griddle crackled, the server flashed a friendly smile, and the aroma of toasted rye and sweet caramelized onions filled the air before the plate hit the table. One bite was all it took to make me a lifelong fan.
Over the years, I’ve dialed in my own homemade version. The real magic goes beyond the secret sauce (though it’s hard to resist). It’s about evenly browning the bread, slowly caramelizing the onions until they’re rich and golden, and letting the cheese melt into every layer. Master those details, and the diner classic won’t even compare—you’ll be proudly serving up your own.

Instructions
1. Caramelize the Onions
Heat the butter and olive oil in a skillet over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring often, until soft, golden, and caramelized, about 12–15 minutes. Remove from the pan and set aside.

2. Make the Patties
In a bowl, mix the ground beef with Worcestershire sauce, garlic powder, onion powder, smoked paprika, salt, and pepper. Shape into four thin patties roughly the size of your bread. Cook in a skillet over medium-high heat for 3–4 minutes per side, until nicely browned and cooked through. Transfer to a plate.
3. Prepare the Secret Sauce
Stir together the mayonnaise, ketchup, mustard, diced pickles, smoked paprika, and garlic powder until smooth. Set aside.
4. Assemble the Patty Melts
Butter one side of each slice of bread. On the unbuttered side, layer in this order: bread, cheese, beef patty, caramelized onions, secret sauce, another slice of cheese, and top with the second slice of bread.
5. Grill the Sandwiches
Heat a skillet or griddle over medium heat. Cook the sandwiches for 2–3 minutes per side, until the bread is golden and the cheese is fully melted. Gently press with a spatula to help everything come together.
Tip: Serve with crispy fries or a pickle spear for the full diner-style experience.
