1. Make the Secret Sauce:
In a small bowl, whisk together mayo, ketchup, mustard, relish, garlic powder, paprika, and black pepper. Chill in the fridge for a few minutes to let the flavors meld.
2. Shape and Sear the Patties:
Divide the beef into 4 portions and shape into rectangles or rounds slightly larger than your bread (they will shrink). Season generously with salt and pepper. Cook in a skillet over medium-high heat for 3–4 minutes per side. Remove and set aside.
Tip: If adding caramelized onions, cook them in the beef fat left in the pan for extra flavor.
3. Assemble the Melts:
Butter one side of all 8 slices of bread. On the non-buttered side of 4 slices, layer:
- Slice of cheese
- Cooked beef patty
- Onions/mushrooms (optional)
- Dollop of secret sauce
- Second slice of cheese
- Top with remaining bread, butter side up
4. Grill to Golden Perfection:
Heat skillet over medium heat. Cook “low and slow” so the bread turns golden as the cheese melts. Grill 3–4 minutes per side, pressing gently with a spatula.
5. Rest and Serve:
Let the melts rest for 1 minute to allow the cheese to set slightly. Slice diagonally and serve hot.
