Instructions

1. Step 1: Heat 2 tbsp unsalted butter in a skillet over medium-low heat. Add 1 large thinly sliced yellow onion and cook, stirring occasionally, for 20-25 minutes until deeply golden and caramelized. Remove from heat.
2. Step 2: Meanwhile, divide 1 lb ground beef into 4 equal portions and form into patties about 3/4-inch thick. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
3. Step 3: Heat 1 tbsp olive oil in a separate skillet or grill pan over medium-high heat. Cook patties for 4 minutes on the first side until browned, then flip and cook 3 minutes more. Place 1 slice smoked cheddar cheese on each patty and cover the pan to melt cheese for 1-2 minutes.
4. Step 4: Toast 4 brioche buns cut side down in the skillet until golden, about 1 minute.
5. Step 5: Assemble burgers by spreading 1 tbsp mayonnaise on each bun bottom, topping with lettuce leaf, tomato slice, a cheesy patty, and a generous spoonful of caramelized onions. Cap with the bun tops and serve immediately.
