Ingredients
  

Patty Melt Ingredients

  • 1 lb ground beef (80/20)
  • 2 large yellow or sweet onions
  • 1 tbsp vegetable oil (for onions)
  • 1 tsp Worcestershire sauce
  • 1 tbsp vegetable oil (for patties)
  • 8 slices rye bread
  • 4 slices Swiss cheese (or Provolone, Cheddar, Monterey Jack)
  • Unsalted butter (for bread)
  • Salt and black pepper to taste

Instructions
 

Caramelize Onions

  • Thinly slice the onions and cook them in a large skillet with oil and salt over medium-low heat for 15-20 minutes until soft and golden.
  • Add Worcestershire sauce and continue cooking for another 10-15 minutes until deeply caramelized and rich golden-brown, then set aside.

Form and Cook Patties

  • While the onions cook, divide the ground beef into equal portions and form into thin patties, seasoning generously with salt and pepper.
  • In the same or a separate skillet, heat oil over medium-high heat and cook the patties for 3-4 minutes per side for desired doneness, then set aside.

Assemble and Grill Patty Melts

  • Butter one side of each rye bread slice and place two butter-side down in the clean skillet over medium heat.
  • On each bread slice, layer a slice of cheese, a cooked patty, caramelized onions, and another slice of cheese, then top with remaining buttered bread slices.
  • Cook for 3-5 minutes per side until golden brown and crispy, and the cheese is melted and gooey, gently pressing with a spatula.
  • Carefully remove, slice in half, and serve hot immediately.

Notes

For extra flavor, consider adding a pinch of garlic powder or a dash of hot sauce to your caramelized onions. If you prefer a richer flavor, you can use butter instead of vegetable oil to cook the beef patties. To prevent the patty from shrinking too much, make a small indentation in the center of each patty before cooking.
