- 1/4 teaspoon paprika
- 1/4 teaspoon garlic powder
Patty Melts:
- 2 tablespoons olive oil
- 2 large onions, thinly sliced
- 12 oz 85/15 lean ground beef
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon Worcestershire sauce
- 8 slices rye bread
- 3 tablespoons unsalted butter, softened
- 4 Swiss cheese slices
- 4 cheddar cheese slices
Instructions
1. Make the Secret Sauce:
Combine mayonnaise, ketchup, Dijon mustard, pickle juice, paprika, and garlic powder in a small bowl. Whisk until smooth and set aside.
2. Caramelize the Onions:
Heat olive oil in a skillet over medium-low heat. Add sliced onions and cook for 30–40 minutes, stirring occasionally, until golden and jammy. If the onions stick, add a splash of water.
3. Cook the Patties:
In a bowl, mix ground beef with salt, pepper, and Worcestershire sauce. Shape into four thin, oval patties.
Cook in the same skillet over medium heat for 2–3 minutes per side until browned. Remove and set aside.
4. Assemble the Sandwiches:
Spread butter on one side of each bread slice. Layer bottom slices (butter-side down) with Swiss cheese, beef patty, caramelized onions, secret sauce, cheddar cheese, and top with remaining bread (butter-side up).
5. Cook the Patty Melts:
In a skillet over medium heat, cook sandwiches in batches until golden brown on both sides and cheese is melted, about 1–2 minutes per side.
Storage
- Store leftover secret sauce in the fridge for up to 5 days.
- Assemble and cook patties fresh for best results; sandwiches are best enjoyed hot.
