What is a Patty Melt?

A patty melt is a classic American sandwich made with a juicy hamburger patty, melted cheese (usually Swiss), grilled onions, and sometimes mustard or ketchup, all sandwiched between two slices of bread and pan-fried until golden brown. It’s like a cross between a cheeseburger and a grilled cheese — but better!

Step-by-Step Instructions: How to Make Patty Melts with Secret Sauce

Step 1: Prepare the Secret Sauce

In a small bowl, combine all the ingredients for the secret sauce . Stir well, cover, and refrigerate while preparing the rest of the meal. Letting it chill enhances the flavors.

Pro Tip: Make the sauce ahead of time and let it sit for 30 minutes before serving for deeper flavor development.

Step 2: Cook the Patties

In a bowl, mix ground beef, salt, pepper, Worcestershire sauce, and chopped onion.
Form into 4 equal patties.
Heat a skillet over medium-high heat. Add a little oil and cook the patties for about 3–4 minutes per side, or until nicely browned and cooked through.

Step 3: Caramelize the Onions

In the same skillet (lower the heat to medium), add a splash of olive oil.
Add sliced onions and cook slowly for about 15–20 minutes, stirring occasionally, until golden brown and sweet.
Season lightly with salt and pepper.

Step 4: Assemble the Patty Melts

Place a slice of Swiss cheese on each patty while still hot so it begins to melt.
Spread a generous amount of secret sauce on one side of each bread slice.
Layer the patty with melted cheese onto two slices of bread, top with caramelized onions, then close with the other slice.

Step 5: Grill the Sandwiches

Wipe the skillet clean and return to medium-low heat.
Butter the outside of each sandwich.
Grill each side for 3–4 minutes until golden brown and crispy, pressing gently with a spatula.

Serve immediately and enjoy your ultimate patty melt with secret sauce !
