Ingredients

Instructions

  1. Step 1: Heat 2 tbsp unsalted butter in a medium skillet over medium-low heat. Add 1 large thinly sliced yellow onion and cook slowly for 20-25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Remove from heat.
  2. Step 2: While onions cook, divide 1 lb ground beef into 4 equal portions and form into patties about 3/4-inch thick. Season both sides of each patty with 1 tsp salt and 1/2 tsp black pepper.
  3. Step 3: Preheat a grill or grill pan to medium-high heat (400°F). Brush 4 burger buns with 1 tbsp olive oil and toast on the grill for 1-2 minutes until golden.
  4. Step 4: Grill beef patties for 4 minutes on the first side until nicely seared, then flip. Place 1 slice cheddar cheese on each patty and cook for an additional 3 minutes until cheese melts and patties reach desired doneness.
  5. Step 5: Assemble burgers by layering lettuce leaf, tomato slices, the cheesy beef patty, and a generous spoonful of caramelized onions on each toasted bun bottom. Top with the bun lid and serve immediately.
