Tools & Equipment Needed

• Skillet or grill pan

Step-by-Step Instructions

1. Prepare Caramelized Onions:
   Heat olive oil in a skillet over medium heat. Add sliced onions, stirring occasionally until they start to soften. Add sugar, salt, and pepper. Continue cooking for 10–15 minutes, stirring frequently, until onions are golden brown and caramelized. Set aside.
2. Make the Secret Sauce:
   In a small bowl, combine mayonnaise, Dijon mustard, ketchup, pickle relish, Worcestershire sauce, smoked paprika, salt, and pepper. Stir until smooth. Set aside.
3. Prepare the Patties:
   Divide the ground beef into 4 equal patties. Season both sides with salt and pepper. Heat a skillet or grill pan over medium-high heat and cook patties 4–5 minutes per side until cooked to desired doneness.
4. Assemble the Patty Melts:
   Butter one side of each slice of rye bread. On the non-buttered side of 2 slices, spread a generous amount of secret sauce. Place a cooked patty on top of each slice, then layer with Swiss and American cheese and caramelized onions. Top with remaining bread slices, buttered side up.
5. Toast the Sandwiches:
   Heat a large skillet or griddle over medium heat. Place sandwiches in skillet and cook 3–4 minutes per side, pressing lightly with a spatula, until bread is golden brown and cheese is melted.
6. Serve:
   Remove from heat, cut sandwiches in half, and serve immediately.
