Description
A hearty and comforting sandwich featuring juicy ground beef patties, caramelized Vidalia onions, and a tangy homemade secret sauce, all nestled between slices of buttery, toasted marble rye with layers of cheddar and Swiss cheese.
Ingredients
- 1.5 lbs lean ground beef
- 1 tbsp Worcestershire sauce
- Salt and black pepper to taste
- 12 slices marble rye bread
- 6 slices cheddar cheese
- 6 slices Swiss cheese
- 2 large Vidalia onions, thinly sliced
- 4 tbsp butter, divided
- 1/4 cup mayonnaise
- 1 tbsp Dijon mustard
- 1 tbsp barbecue sauce
- 1 tsp hot sauce
Instructions
- Mix mayonnaise, Dijon mustard, barbecue sauce, and hot sauce in a small bowl to make the secret sauce. Chill until ready to use.
- In a large bowl, combine ground beef, Worcestershire sauce, salt, and pepper. Mix gently and shape into six oval patties.
- Melt 2 tablespoons butter in a skillet over medium-low heat. Add sliced onions and cook for 20 minutes, stirring occasionally until caramelized.
- In a separate skillet, cook patties over medium-high heat for about 2 minutes per side, just enough to form a crust.
- Butter the outer sides of each bread slice. On the inside, spread secret sauce, then layer with onions, cheese, a patty, more cheese, onions, additional sauce, and top with another bread slice (butter side out).
- Wipe out the skillet and heat over medium. Toast sandwiches for 3-4 minutes per side until golden and cheese is melted.
Notes
- Make the secret sauce a day ahead for deeper flavor.
- Use a spatula to press sandwiches lightly for even toasting.
- Substitute different cheeses or breads to customize flavor.
- For added crunch, include pickles.
