# Ingredients You'll Need:
→ Beef Patties
01 -
680 grams lean ground beef
02 -
1 tablespoon Worcestershire sauce
03 -
1 teaspoon sea salt
04 -
1/2 teaspoon freshly ground black pepper
→ Secret Sauce
05 -
1/2 cup full-fat mayonnaise
06 -
1 tablespoon Dijon mustard
07 -
1 tablespoon barbecue sauce
08 -
1 teaspoon hot sauce
→ Sandwich Assembly
09 -
12 slices marble rye bread
10 -
6 slices Swiss cheese
11 -
6 slices cheddar cheese
12 -
3 tablespoons unsalted butter, softened
13 -
2 large Vidalia onions, thinly sliced
# Steps to Follow:
01 -
In a small bowl, whisk together mayonnaise, Dijon mustard, barbecue sauce, and hot sauce until smooth and well blended.
02 -
In a large bowl, gently combine ground beef with Worcestershire sauce, salt, and pepper until evenly mixed. Avoid overworking the meat.
03 -
Divide the seasoned beef into six oval patties, slightly wider than the bread. Flatten lightly to maintain shape while cooking.
04 -
In a large skillet over medium heat, melt butter and add sliced onions. Cook for 20–25 minutes, stirring often, until onions are soft, golden, and fragrant.
05 -
Heat a clean skillet over medium-high. Cook patties for 2 minutes per side until browned but still juicy. Remove and wipe the skillet clean.
06 -
Spread softened butter on one side of each bread slice. Keep bread cool to prevent tearing during spreading.
07 -
Place six bread slices buttered-side down in a skillet. Spread 1 tablespoon of sauce, then layer onions, cheddar cheese, beef patty, Swiss cheese, more onions, a drizzle of sauce, and top with another bread slice buttered-side out.
08 -
Cook over medium heat, pressing gently with a spatula. Flip when golden and repeat until cheese is melted and bread is crisp. Let rest before slicing.
# Extra Tips:
01 -
Layering cheese on both sides of the patty enhances melt and texture.
02 -
Caramelized onions can be made in advance and refrigerated for quicker assembly.
03 -
Use sturdy bread like sourdough if marble rye is unavailable.
