Ingredients
Scale
- 1 pound (450g) ground beef (80/20 blend)
- 2 medium yellow onions, thinly sliced
- Salt, to taste
- Freshly ground black pepper, to taste
- 1 tablespoon vegetable oil or beef tallow
- 4 soft burger buns, lightly toasted (potato buns preferred)
- Cheese slices (optional, American or cheddar)
- Lettuce, tomato slices, pickles, and favorite sauces (mayo, mustard, ketchup) for topping
Instructions
- Heat 1 tablespoon of vegetable oil or beef tallow on the griddle over medium-low heat. Add thinly sliced yellow onions and a pinch of salt. Cook slowly, stirring occasionally, for 20-25 minutes until deeply golden and caramelized. Add a splash of water if onions start sticking.
- Divide ground beef into 4 equal portions (about 4 ounces or 115g each). Loosely form each into balls without packing tightly.
- Preheat the griddle to medium-high heat. Add a little oil to the surface to prevent sticking.
- Place beef balls on the hot griddle spaced apart. Using a sturdy metal spatula or burger press, firmly smash each ball down to about 1/4 inch (6 mm) thickness. Hold pressure for 10-15 seconds to form a crust. Do not move patties once smashed.
- Immediately season each patty with salt and freshly ground black pepper.
- Cook patties for 2-3 minutes until edges are deeply browned and crispy. Flip carefully, add cheese slices if using, and cook another 1-2 minutes until cheese melts and burger is cooked through.
- Toast buns on the griddle for 1-2 minutes until golden and slightly crisp.
- Assemble burgers by placing patties on toasted buns, topping generously with caramelized onions and desired toppings and sauces. Serve immediately.
Notes
Use an 80/20 ground beef blend for best juiciness and crust. Slowly caramelize onions over low heat for best flavor. Press patties firmly and hold to create a crispy crust. Avoid overworking the meat to keep burgers tender. For gluten-free, use lettuce wraps or gluten-free buns. Reheat leftovers gently in a skillet to maintain crust.
