Step 1: In a large mixing bowl, gently combine the ground beef, breadcrumbs, Worcestershire sauce, minced garlic, onion powder, salt, and black pepper. Mix just until everything is combined; do not overwork the meat.
Step 2: Divide the meat mixture into four equal portions. Gently form each portion into a patty, about 3/4 to 1 inch thick and slightly wider than your burger buns.
Step 3: Make a slight indentation (dimple) in the center of each patty with your thumb to prevent it from bulging during cooking.
Step 4: Heat a large cast-iron skillet or heavy-bottomed pan over medium-high heat. Add olive oil or butter. Once shimmering, carefully place the patties in the hot pan, ensuring not to overcrowd. Cook in batches if necessary.
Step 5: Cook for 3-5 minutes per side for medium-rare to medium doneness, or longer for desired doneness (internal temperature of 130-140°F / 54-60°C).
Step 6: If adding cheese, place a slice on top of each patty during the last minute of cooking, covering the pan with a lid for a moment to help it melt perfectly.
Step 7: Once cooked, remove patties from the pan and let them rest on a plate for 5 minutes to allow the juices to redistribute.
Step 8: Serve immediately on toasted buns with your favorite toppings, or use as a base for other hamburger meat recipes.
