Step 1: In a large mixing bowl, gently combine ground beef, egg, breadcrumbs, Worcestershire sauce, onion powder, garlic powder, salt, and black pepper.
Step 2: Use your hands and mix the ingredients just until combined. Avoid overmixing, as this can lead to tough patties.
Step 3: Divide the meat mixture into 6 equal portions. Lightly wet your hands with cold water to prevent sticking, then gently form each portion into a patty about 3/4 to 1 inch thick.
Step 4: Create a small indentation (about 1/2 inch deep) in the center of each patty with your thumb. This helps the patty cook evenly and retain its shape.
Step 5: Place the formed patties on a plate or baking sheet lined with parchment paper. If not cooking immediately, cover and refrigerate for at least 30 minutes to firm up.
Step 6: Preheat your grill to medium-high heat (about 400-450°F / 200-230°C) or a cast-iron skillet over medium-high heat. Lightly oil the cooking surface.
Step 7: Place the patties on the hot grill or skillet. Cook for 4-5 minutes per side for medium-rare, 5-6 minutes per side for medium, or 6-7 minutes per side for well-done.
Step 8: Avoid pressing down on the patties with your spatula while cooking, as this expels juices. Flip only once during cooking.
Step 9: If adding cheese, place a slice on top of each patty during the last 1-2 minutes of cooking to allow it to melt.
Step 10: Remove the cooked patties from the heat and let them rest for 5 minutes before serving. This allows the juices to redistribute for a tender and juicy burger. Serve on your favorite buns with desired toppings.
