This classic Patty Melt recipe features juicy ground beef patties topped with caramelized onions and Swiss cheese, all sandwiched between crispy rye bread slices spread with mayonnaise. Perfectly pan-fried until golden brown and melty, this hearty sandwich makes a satisfying lunch or dinner.

Ingredients

Main Ingredients

  • 4 tablespoons butter (divided)
  • 2 medium onions (thinly sliced)
  • 1 pound ground beef
  • salt and pepper (to taste)
  • 8 slices rye bread (or your favorite sandwich bread)
  • 4 tablespoons mayonnaise
  • 8 slices Swiss cheese

Instructions

  1. Caramelize Onions: Melt 2 tablespoons of butter in a large skillet over medium heat. Add the thinly sliced onions and cook for 25 minutes, stirring occasionally, until they are deeply golden and caramelized. Reduce heat to medium-low if they start to burn. Transfer onions to a plate and wipe skillet clean.
  2. Prepare Beef Patties: Season the ground beef with salt and pepper. Divide it into 4 equal portions and shape each into a patty roughly the size of the bread slices.
  3. Cook Patties: Place the patties in the clean skillet over medium-high heat and cook for 3 minutes per side until browned and cooked through. Remove patties to a plate and wipe the skillet clean again.
  4. Toast Bread Slices: Melt 1 tablespoon butter in the skillet. Add 4 slices of bread and toast until golden brown. Remove 2 toasted slices, then flip the other 2 slices to toast the other side.
  5. Assemble Sandwiches: On the side of the bread currently in the skillet, place a slice of Swiss cheese, then add a cooked patty, a generous layer of caramelized onions, and another slice of cheese. Spread 1 tablespoon mayonnaise on the untoasted side of the remaining toasted bread slices, then place these mayo sides atop the assembled sandwiches in the skillet.
  6. Grill Sandwiches: Turn heat to medium-low and cook the sandwiches for 4 minutes, flipping halfway through, until the bread is toasted evenly and the cheese has melted.
  7. Repeat Process: Remove finished sandwiches and repeat the toasting and assembling process with the remaining ingredients.
  8. Serve: Slice the sandwiches in half and serve immediately with chips or french fries for a classic meal experience.

Notes

  • Caramelizing onions is a slow process that cannot be rushed; cooking them slowly at lower heat releases their natural sugars for maximum flavor.
  • Wiping the skillet clean between cooking different ingredients prevents burning and preserves flavor.
  • Cook assembled sandwiches at medium-low heat to toast evenly and melt cheese without burning the bread.
  • Leftover grilled patty melts can be stored in the refrigerator for up to 3 days.
