Preheat your grill or cast-iron skillet over medium-high heat, adding a splash of oil if using a skillet.

Form the ground beef into four loose balls (about 4 ounces each) without compacting them too tightly.

Season each ball with salt and pepper.

Once hot, place the beef balls on the grill/skillet and smash them down firmly with a spatula to create flat patties.

Cook for about 2 minutes until browned; add cheese on top and cover to melt while cooking for an additional minute.

Toast the burger buns cut-side down until golden brown.

Assemble your burgers by adding toppings and sauces as desired.
