Begin by dividing the ice-cold ground beef into four equal portions, roughly 4 ounces each. Gently roll each portion into loose balls without compressing them too tightly, ensuring they remain chilled until ready to cook.

Preheat a cast iron skillet over medium-high heat until it starts to lightly smoke, creating the perfect environment for a sear.

Carefully place the beef balls onto the hot skillet, leaving space between each. Using a heavy slotted spatula, press down firmly on each ball until they flatten into irregular patties, about ½ inch thick.

Once flattened, generously season the patties with kosher salt and freshly cracked black pepper. Let them cook undisturbed for about 2 minutes, or until the edges start to char and develop a rich golden crust.

Carefully flip each patty using your spatula, and immediately place a slice of yellow American cheese on top of each one. Cover the skillet with a dome or lid for about 30 seconds to allow the cheese to bubble and ooze delightfully over the patties.

Once the cheese is melted and gooey, assemble your Crispy Diner-Style Double Cheeseburger by placing the cheesy patties on your toasted brioche buns, spreading your favorite burger sauce on top, and stacking the patties.
