Instructions

  1. Step 1: Place 1/2 cup white vinegar and 1 tbsp granulated sugar in a small saucepan over medium heat. Stir until sugar dissolves, then add 1 medium thinly sliced yellow onion. Simmer for 5 minutes, then remove from heat and let cool to create quick pickled onions.
  2. Step 2: Divide 1 lb ground beef into 4 equal portions and form into 4 patties about 3/4-inch thick. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
  3. Step 3: Heat a large skillet or griddle over medium-high heat. Add 2 tbsp unsalted butter and let melt, then add the patties. Cook for 3-4 minutes on the first side until browned.
  4. Step 4: Flip the patties, place 1 slice American cheese on each, and cook for another 3 minutes until cheese melts and patties reach 160°F internal temperature.
  5. Step 5: While the patties cook, toast 4 burger buns with the remaining 2 tbsp unsalted butter spread on cut sides, toasting on the skillet until golden and fragrant.
  6. Step 6: Assemble the burgers by placing each patty on a toasted bun bottom, topping with a generous spoonful of pickled onions, and covering with the bun top before serving.
