Preheat a large cast-iron skillet or griddle over high heat for about 5 minutes.

Divide ground beef into four portions of approximately 4 ounces each and form into loose balls.

Place beef balls onto the hot surface and smash each into half-inch thick patties.

Season with salt and pepper, cook for about 2-3 minutes until edges are brown, then flip and cook until internal temperature reaches 160°F.

Melt a tablespoon of butter in a separate skillet, then toast the burger buns cut side down until golden brown.

Assemble your burgers by layering the bottom bun with a patty and your favorite toppings, then finish with the top bun.
