01 - Gently mix ground beef with salt, pepper, and Worcestershire sauce. Shape into 4 equal patties, slightly wider than the buns to account for shrinkage during cooking.
02 - Preheat a grill or skillet over medium-high heat. Cook beef bacon until crispy, about 3–4 minutes per side. Transfer to a paper towel-lined plate to drain.
03 - Grill or pan-sear burger patties for 3–4 minutes per side until reaching desired doneness. During the final minute, place cheddar cheese on each patty to melt.
04 - Lightly toast the split brioche buns until golden and warm.
05 - Spread mayonnaise and Dijon mustard evenly on the cut sides of the toasted buns.
06 - Layer lettuce on the bottom bun, add the cheese-topped beef patty, followed by avocado slices, crispy beef bacon, tomato, and red onion. Crown with the top bun.
07 - Serve immediately while warm.
