Step-by-Step Instructions
1. Caramelize the Onions
Melt the butter and olive oil in a skillet over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring frequently, until soft, golden, and sweet — about 12–15 minutes. Remove from heat and set aside.
2. Prepare the Patties
In a bowl, combine ground beef with Worcestershire sauce, garlic powder, onion powder, smoked paprika, salt, and pepper. Gently mix and form into 4 thin patties about the size of your bread slices.
Cook in a hot skillet over medium-high heat for 3–4 minutes per side until browned and cooked through. Transfer to a plate.
3. Make the Secret Sauce
In a small bowl, stir together mayonnaise, ketchup, mustard, pickles, paprika, and garlic powder until smooth. Chill until ready to use.
4. Assemble the Patty Melts
Butter one side of each bread slice. On the unbuttered side layer:
- Bread
- Cheese slice
- Beef patty
- Caramelized onions
- Secret sauce
- Another cheese slice
- Top bread slice
5. Grill the Sandwiches
Heat a skillet or griddle over medium heat. Cook each sandwich 2–3 minutes per side until the bread is golden brown and the cheese is fully melted. Press gently with a spatula.
Serving Suggestions
- Classic French fries or sweet potato fries
- Pickle spears or coleslaw
- Tomato soup or onion rings
Pro Tips for the Best Patty Melt
- Use 80/20 beef for maximum juiciness.
- Don’t rush the onions — slow caramelization brings the sweetness.
- Spread butter edge-to-edge for evenly crispy bread.
- Cover the pan briefly while grilling to help melt the cheese faster.
