Crispy-edged smash burgers with Worcestershire-balsamic caramelized onions, tangy burger sauce, and strategic pickle placement
Heat butter and oil on griddle over medium heat. Add onions with salt and cook 10-15 minutes until golden. Add Worcestershire and balsamic glaze, cook 2-3 minutes more. Set aside.
Mix burger sauce ingredients in bowl until smooth. Refrigerate until needed.
Preheat griddle to 450-500°F. Form ground beef into loose 3-4 oz balls without compacting.
Place beef balls on hot griddle and smash immediately with firm pressure. Season with salt and pepper. Cook 1½-2 minutes until edges are crispy.
Flip patties, add cheese, and cook 1 minute more. Toast buns cut-side down on griddle.
Assemble: pickles on bottom bun, add cheesy patty, caramelized onions, and burger sauce on top bun. Serve immediately.
