01 - Preheat a grill or large skillet over medium-high heat until thoroughly hot.
02 - In a large bowl, combine ground beef with kosher salt, black pepper, smoked paprika, garlic powder, and onion powder. Mix gently until just incorporated—avoid overworking the meat. Divide into 4 equal portions and shape into patties slightly wider than the buns to account for shrinkage during cooking.
03 - While the grill heats, whisk together mayonnaise, barbecue sauce, Dijon mustard, hot sauce, and brown sugar in a small bowl until smooth and well combined. Set aside.
04 - Melt butter in a skillet over medium heat. Place buns cut-side down and toast until golden brown, about 1 to 2 minutes. Remove and set aside.
05 - Place patties on the hot grill or skillet and cook for 3 to 4 minutes per side until desired doneness is reached. During the final minute of cooking, lay a slice of cheddar cheese on each patty and allow it to melt.
06 - Spread the signature sauce generously on both halves of each toasted bun. Layer the bottom bun with shredded lettuce, tomato slices, and red onion rings. Place the cheesy patty on top, followed by 2 slices of crispy bacon. Cap with the top bun.
07 - Serve immediately while hot. Offer additional sauce on the side along with your choice of fries or salad.
