In a large mixing bowl, combine 1 pound of ground beef, 1 beaten egg, 2 tablespoons of Worcestershire sauce, 1 tablespoon of brown mustard, and 2 tablespoons of chopped unsalted butter. Sprinkle in ½ cup of breadcrumbs, ¼ cup of grated Parmesan cheese, and 2 cloves of minced garlic. Gently mix the ingredients with your hands until just combined.

Once the mixture is prepared, divide it into four equal portions and shape each into a patty about ¾ inch thick. Make a slight indentation in the center of each patty.

Before grilling, generously season the top of each patty with your favorite seasoning. Let the patties rest for about 10–15 minutes at room temperature.

Preheat your grill to high heat, around 450°F to 500°F, ensuring the grates are clean and lightly greased.

Carefully place the patties on the hot grill, cooking for 4–5 minutes on one side without pressing down. Flip and grill for another 3–4 minutes.

If you’re a cheese lover, add slices of your favorite cheese onto each patty during the last 1–2 minutes of grilling.

Once cooked to your liking, remove the patties from the grill and let them rest for a few minutes before serving.
