A delicious sourdough patty melt burger featuring BUBBA burgers made with 100% USDA Choice beef chuck, combined with caramelized onions, sharp white cheddar, and a special BBQ-mayo steak sauce.
1. Place the BUBBA burger on an oiled griddle preheated to 325F. Season with salt and pepper. Do not flip until the juices run to the top, which takes approximately 10 minutes.
2. While the burgers are cooking, sizzle the thin sliced onions in oil on another part of the griddle until softened and caramelized.
3. Flip the burgers, then top each with the cooked onions and a slice of sharp white cheddar cheese.
4. While the burgers continue to cook and the cheese melts, butter both sides of the sourdough bread slices and toast them on the griddle until golden brown.
5. Once the bread is toasty and the cheese is melted, assemble the patty melt by placing the burger on a slice of sourdough and topping with another slice.
6. For the sauce, combine 1/2 cup BBQ sauce, 1/2 cup mayonnaise, and 1 tablespoon steak sauce in a small bowl. Serve the patty melts with the sauce.
