In a large bowl, combine ground beef, minced garlic, Parmesan cheese, Worcestershire sauce, salt, and black pepper. Mix until well incorporated but avoid overmixing to keep the burgers tender.

Divide the mixture into four equal portions and form them into burger patties, making a slight indentation in the center of each to ensure even cooking.

Preheat a grill or skillet over medium-high heat. Place the patties on the grill/skillet and cook for about 5 minutes per side, or until the internal temperature reaches 160°F (71°C) for medium doneness.

During the last minute of cooking, place a slice of cheddar cheese on each patty and cover with a lid or foil to allow the cheese to melt.

Toast the hamburger buns if desired. On the bottom half of each bun, layer lettuce leaves and tomato slices. Place the cooked burger patty on top.

Spread mayonnaise and ketchup on the inside of the top bun, then place it over the patty to complete the burger.

Serve immediately with your favorite sides, like fries, onion rings, or a fresh salad.
