Heat a griddle or cast-iron skillet over medium-high heat. The surface should be hot enough to sizzle upon contact with the meat.
Form the Patties
Divide the ground beef into 4 equal portions and gently roll them into loose balls. Do not overwork the meat to ensure a tender burger.
Smash the Patties
Place a ball of beef on the hot griddle. Immediately press it down firmly with a sturdy spatula (or burger press) until it’s about ½ inch thick. Season generously with salt and pepper.
Sear to Perfection
Cook the patties for about 2 minutes until the edges are crispy and the bottom develops a deep brown crust. Flip the patties, add a slice of cheese to each, and cook for another minute until the cheese melts.
Prepare the Buns
Toast the hamburger buns on the griddle until lightly crisp.
Assemble the Burger
Place the cheesy patty on the bottom bun, then layer with lettuce, tomato, onions, pickles, and your favorite condiments.
Serve and Enjoy
Enjoy your homemade smash burger hot off the griddle, paired with fries or your favorite side.
