Spray a griddle with nonstick spray and toast your buns over medium heat.
02 -
Divide the ground beef into 4 equal portions. Keep them loosely gathered; do not form into patties yet.
03 -
Place a handful of sliced onions on the hot griddle. Put a ball of ground beef on top of the onions.
04 -
Smash the beef into the onions using a sturdy spatula, creating about 1/4 inch thick patties. Season with salt, black pepper, and garlic powder.
05 -
Cook each patty for 2-3 minutes until the edges are crispy. Flip, cooking for another minute. Add a slice of cheese to each patty and let it melt.
06 -
Assemble the burgers by placing each patty on a toasted bun. Add your preferred condiments and optional toppings. If you're looking for a double burger, just top two patties on one bun. Serve and enjoy!.
