The History of the Patty Melt

Before diving into the ingredients and preparation, let’s appreciate where this sandwich comes from. The patty melt is said to have originated in American diners sometime in the 1940s or 1950s. It was born from a natural evolution — combining the juicy hamburger with a grilled cheese sandwich. Typically served on rye bread, the classic patty melt features sautéed or caramelized onions and Swiss cheese, offering a savory flavor combo that remains a staple today. Over the years, variations have emerged to suit regional preferences, with different cheeses, sauces, and bread types, but the soul of the sandwich has always stayed the same.

Why You’ll Love This Version

This version of the patty melt takes the standard up a notch with two kinds of cheese and a zingy secret sauce that brings everything together. The mix of Swiss and cheddar cheese creates the perfect harmony of meltiness and sharpness, while the secret sauce — a tangy, slightly spicy blend of mayo, Dijon mustard, BBQ sauce, and hot sauce — adds just the right amount of kick.

 Ingredients (US Measuring Cups)

For the Beef Patties:

  • 1.5 lbs lean ground beef
  • 2 tsp Worcestershire sauce
  • 1 tsp salt
  • ½ tsp ground black pepper

For the Secret Sauce:

  • ¼ cup mayonnaise
  • ¼ cup Dijon mustard
  • 1 tbsp barbecue sauce
  • ½ tsp hot sauce (adjust to taste)

For the Sandwich Assembly:

  • 12 slices marble rye bread
  • 3 slices cheddar cheese
  • 3 slices Swiss cheese
  • 8 tbsp unsalted butter (for grilling bread)
  • 3 medium Vidalia onions, thinly sliced
  • ½ cup prepared secret sauce (see above)

 Instructions

Step 1: Make the Secret Sauce

In a small bowl, whisk together mayonnaise, Dijon mustard, BBQ sauce, and hot sauce until smooth. Adjust seasoning to taste. Store in the fridge until ready to use.

Step 2: Prepare the Onions

Melt 4 tablespoons of butter in a large skillet over medium-low heat. Add the sliced onions and stir to coat in the butter. Cook slowly, stirring occasionally, until the onions are golden and caramelized, about 15–20 minutes. Set aside.

Step 3: Form the Beef Patties

In a large bowl, combine the ground beef, Worcestershire sauce, salt, and black pepper. Mix gently with your hands until just combined — don’t overwork the meat. Divide into six equal oval-shaped patties, slightly larger than your bread slices.

Step 4: Cook the Patties

Heat a grill pan or large skillet over medium-high heat. Cook the patties for 2–3 minutes per side until browned and cooked through (internal temperature should reach 160°F). Transfer to a plate and rest briefly.

Step 5: Assemble the Sandwiches

Lay out the slices of rye bread. Spread about 1 tablespoon of secret sauce on one side of each slice. On six of the slices, layer Swiss cheese, a beef patty, caramelized onions, cheddar cheese, and top with another slice of sauced bread.

Step 6: Grill the Sandwiches

Melt the remaining butter in a skillet or griddle over medium heat. Working in batches, grill the sandwiches for 2–3 minutes per side until the bread is golden brown and crispy, and the cheese is melted. Press gently with a spatula for even grilling.

 Tips for the Perfect Patty Melt

  • Bread Matters: Marble rye offers the best combo of flavor and structure, but you can also try sourdough or Texas toast.
  • Cheese Combo: The mix of Swiss and cheddar gives the sandwich both classic and bold flavors. American cheese is a good melty substitute.
  • Sauce Swap: If you don’t want to make the secret sauce, Thousand Island dressing or even Russian dressing makes a good alternative.
  • Caramelized Onion Patience: Low and slow is the key to perfect onions. Don’t rush the process.
  • Make Ahead: Caramelize onions and prep the sauce up to 3 days in advance and store them in the fridge.
  • Customize It: Add crispy bacon, grilled mushrooms, or jalapeños for extra flavor.

Serving Suggestions

Patty melts are hearty on their own, but they go especially well with:

  • Classic French fries or sweet potato fries
  • Dill pickle spears
  • A crisp green salad
  • Coleslaw
  • Creamy tomato soup

Storage & Reheating

Store leftover patty melts wrapped in foil or an airtight container in the refrigerator for up to 3 days. To reheat, place in a skillet over medium heat until warmed through and crispy again, or reheat in an air fryer.
