Place the ground beef in a bowl and gently divide it into four equal portions. Carefully shape each portion into a round patty about 2 cm thick, making a slight indentation in the center of each; this helps the burger cook evenly and prevents puffing up.
Preheat your cast-iron skillet or grill over medium-high heat until hot. Add a small amount of oil or butter to help with searing if using a skillet. The surface should shimmer and give off a fragrant aroma as it heats.
Season each patty generously with salt and pepper just before cooking, pressing lightly to adhere. Place the patties onto the hot surface, listening for a satisfying sizzle.
Sear the patties for about 3-4 minutes on one side, until they develop a deep, golden-brown crust with a slight char and smell of caramelized beef.
Flip the patties carefully with a spatula and cook for another 3-4 minutes on the second side. Use a meat thermometer to check that the internal temperature reaches 70°C (160°F), ensuring safety and juiciness.
If you’re adding cheese, place a slice on each patty during the last minute of cooking to allow it to melt beautifully.
Remove the cooked patties from the heat and let them rest for about 2 minutes; this helps lock in the juices and ensures a tender bite.
While the burgers rest, toast the buns lightly until golden and fragrant. Spread your favorite sauce or condiments on the bun halves.
Assemble the burger by placing a lettuce leaf, tomato slice, onion, pickle, and the juicy patty with melted cheese onto the bottom bun. Top with the other bun and additional toppings or sauce as desired.
Serve immediately with your favorite side, like crispy fries or a fresh salad, and enjoy the smoky, juicy explosion of flavor in every bite.
