• Combine the ground beef, panko breadcrumbs, egg, milk, Worcestershire sauce, paprika, salt, black pepper, garlic powder, and onion powder in a large mixing bowl. Mix just until the ingredients are combined, being careful not to over-mix, or the patties will be tough.
• Divide the meat mixture into six equal portions, then shape each portion into a ball and set aside.

Stovetop Instructions

• Heat a large skillet over medium-high heat. Place one portioned ball on the skillet and gently press it into a ½-inch thick patty using a flat spatula. Tip: Use a spoon to dent the center of each patty as they will puff up as they cook (this is especially important for larger, thicker hamburger patties).
• Cook for 3-4 minutes per side for medium-rare, or longer if you prefer them well-done. 
• Optional: If using cheese, place a slice on top of each of the patties, then turn the heat down to low and cover the pan with a lid and let the cheese fully melt.
• Once the patties are cooked, and the cheese is melted, remove them from the skillet and place them on a plate to rest.

Grill Instructions

• Preheat the grill to medium-high heat, about 375 degrees F.
• Shape each ball into patties using your hands (they should be about ½-¾ - inch thick. Use the back of a spoon to make an indent in the center of each patty. Add each burger patty to the grill and cook for 3-4 minutes per side. Add cheese if desired.
• Once the patties are cooked remove them from the grill and place them on a plate to rest.
• To assemble, spread mayonnaise on the top and bottom halves of the buns before placing a patty on the bottom bun, followed by lettuce, tomato, pickles, and red onion, if desired.
