Ingredients

Instructions

  1. Step 1: Divide beef into 4 equal portions (3 oz each). Form into loose patties, pressing a slight indentation in the center. Season both sides with 1/4 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Thinly slice onion and melt 2 tbsp butter in a skillet over medium heat. Add onions and cook for 15-18 minutes, stirring occasionally, until deeply golden and caramelized — reduce heat if browning too quickly.
  3. Step 3: Grill patties on a preheated grill or skillet for 4-5 minutes per side for medium doneness. Top with cheddar slices during the last minute of cooking until melted.
  4. Step 4: Mix mayonnaise and Dijon mustard. Toast brioche buns lightly. Assemble burgers with sauce, patty, and caramelized onions on bottom bun.
