Divide the chilled ground beef into four equal loosely packed balls, handling them gently to maintain juiciness.
Heat your cast iron skillet over medium-high heat until it’s hot and begins to smoke slightly, indicating it’s ready for the patties.
Lightly brush the skillet with neutral oil to prevent sticking and help develop a crispy crust.
Place a beef ball onto the hot skillet and immediately press down firmly with a sturdy spatula to flatten it into a thin patty, aiming for even thickness.
Sprinkle salt and pepper evenly over the patty while it’s sizzling, enhancing flavor and crust formation.
Cook for about 2-3 minutes until the edges are dark golden and crispy, then flip carefully with your spatula, hearing a satisfying crackle as the crust forms.
Immediately place a slice of cheese on top of the flipped patty and cook for another minute until melted and gooey.
While the cheese melts, toast the buns lightly in the same skillet or in a toaster, until golden and crisp.
Remove the cooked patties and buns from the skillet, and assemble the burger by placing the cheesy patty on the bottom bun, then adding pickles and the top bun.
Serve immediately, with a side of crispy edges and melted cheese, enjoying the combination of crunch and juicy beef with each bite.
