Divide the ground beef into four equal portions and roll each into a ball.

Preheat a griddle or cast iron skillet over medium-high heat.

Place a ball of beef on the hot griddle. Cover with parchment paper and press down firmly with a heavy spatula to flatten into a thin patty.

Season the patty with salt and pepper. Cook for about 2-3 minutes until the edges are crispy and browned.

Flip the patty, add a slice of cheese, and cook for another 1-2 minutes until the cheese is melted and the patty is cooked to your liking.

Repeat with the remaining beef balls.

Assemble the burgers by placing each patty on a bun and adding your desired toppings.
