Instructions

  1. Step 1: Divide 1.5 pounds ground beef into 8 equal portions, shaping into 3/4-inch thick patties; press a shallow dimple into the center of each to prevent bulging.
  2. Step 2: Heat a grill to medium-high (375°F) and lightly oil grates. Season patties with 1 tsp sea salt and 1/2 tsp black pepper per patty.
  3. Step 3: Grill patties for 4 minutes per side for medium doneness, adding 8 cheddar cheese slices during the last minute to melt.
  4. Step 4: While burgers cook, thinly slice 2 medium yellow onions and melt 2 tbsp butter in a skillet over medium heat; cook onions for 15 minutes until golden brown, stirring occasionally.
  5. Step 5: Add 2 tbsp bourbon and 1 tbsp balsamic vinegar to the onions, then simmer for 3 minutes until reduced and glossy, stirring to coat onions evenly.
  6. Step 6: Toast brioche buns on the grill for 1 minute until lightly golden, then assemble burgers with caramelized onions on top of each cheese-topped patty.
