In a large mixing bowl, combine 1 pound of lean ground beef, 1 cup of panko breadcrumbs, 1 large egg, ¼ cup of Worcestershire sauce, ¼ cup of milk, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and season with salt and black pepper to taste. Using your hands, gently mix the ingredients until just combined.

Divide the mixture into 8 equal portions, shaping each into patties that are about ¾-inch thick and slightly larger than the buns. Make a small dent in the center of each patty.

Heat your grill or a cast iron skillet over medium-high heat. Lightly oil the surface to prevent sticking.

Place the patties on the hot grill or skillet and cook for 3-4 minutes on one side. Flip the patties only once to achieve a perfect sear. If desired, spread yellow mustard on one side before flipping and cook for another 3-4 minutes.

Once cooked, remove the burgers from the heat and let them rest for 5 minutes before placing them on buns with your favorite condiments.
