Combine ground beef, breadcrumbs, egg, minced onion, Worcestershire sauce, garlic powder, salt, and black pepper in a large bowl. Mix gently with your hands for about 1 minute until ingredients just combine—do not overmix or the meat will become tough and dense. The mixture should hold together loosely.

Divide the mixture into 8 equal portions, gently shaping each into a ball. Press each ball into a 3/4-inch-thick patty with your thumb or the back of a spoon, creating a slight indent in the center. This indent prevents the burger from puffing up as it cooks and ensures even thickness.

Preheat your grill to medium-high heat (around 375°F) for about 5 minutes. Oil the grates lightly to prevent sticking. Juicy grilled burgers crowd recipe requires proper heat management—too hot and the outside burns before the inside cooks through.

Place patties directly on hot grates and resist the urge to press them down with a spatula. Cook undisturbed for 6-7 minutes on the first side until a golden crust forms and juices pool on top. Flip gently once and cook for another 5-6 minutes for medium doneness.

Add cheese slices during the last minute of cooking if desired, covering the grill to help it melt. Toast the buns butter-side down on the grill for 30 seconds just before serving—this prevents soggy bread.

Remove patties to a clean plate and let rest for 2 minutes before assembling. This allows juices to redistribute throughout the meat rather than running onto the plate.

Build your burgers with lettuce on the bun first (creates a barrier preventing sogginess), then patty, cheese, tomato slices, pickles, and your choice of condiments. Serve immediately while everything is hot and the buns are still warm.
