A classic Patty Melt Sandwich featuring juicy ground beef patties, sweet caramelized onions, and melted Swiss cheese sandwiched between buttery grilled sourdough or rye bread. This comforting sandwich is crispy on the outside with a savory, melty center—perfect for a satisfying lunch or dinner.

Ingredients

Burger Patties

  • ½ lb ground beef (80/20 for juiciness)
  • Salt & black pepper, to taste

Onions

  • 1 medium onion, thinly sliced
  • 1 tbsp butter

Sandwich

  • 4 slices sturdy bread (sourdough or rye)
  • 4 slices Swiss cheese (or provolone)
  • Butter, softened (for grilling)

Instructions

  1. Caramelize the onions: Melt butter in a skillet over medium-low heat. Add the thinly sliced onions and cook slowly for 8–10 minutes until they become soft, golden, and sweet. Remove from skillet and set aside.
  2. Cook the patties: Form the ground beef into two thin patties, slightly larger than the bread slices. Season both sides with salt and pepper. Using the same skillet, cook the patties over medium heat for 2–3 minutes per side until fully cooked. Remove and set aside.
  3. Assemble the sandwiches: Butter one side of each bread slice. Place two slices butter-side down on a clean surface. Layer with one slice of cheese, one cooked beef patty, caramelized onions, and another slice of cheese. Top with the remaining bread slices butter-side up.
  4. Grill the sandwiches: Heat the skillet over medium-low heat. Place assembled sandwiches in the skillet and cook for 3–4 minutes on each side until the bread is golden and crispy and the cheese has melted. Press gently with a spatula during grilling to ensure even browning.
  5. Serve: Let the sandwiches rest for 1 minute after cooking. Slice in half and plate for serving.

Notes

  • Use 80/20 ground beef for juicier, more flavorful patties.
  • Caramelizing onions slowly over low heat brings out their natural sweetness.
  • Choose sturdy, hearty bread like sourdough or rye to hold the sandwich together during grilling.
  • Butter the bread generously for a golden, crispy crust.
  • You can substitute Swiss cheese with provolone if preferred.
