In a large bowl, add in the beef, Worcestershire sauce, garlic powder, paprika, salt and pepper.
Using clean hands, knead everything together until combined.
Lightly pat to form into 4 to 6 large hamburger patties.
Use your thumb to make an indention in the center of each hamburger. This will help them keep their shape during cooking.
Cook on a hot grill for about 5 minutes per side or until nearly cooked to your preferred temperature.
About 2 minutes before each burger is done, top with a slice of cheese until melted and bubbly.
Remove the burgers from the grill.
Lightly spread butter on the inside of each bun and place on the grill to toast for 1 minute, until lightly toasted.
Remove the buns from the grill.
Build your burger with your favorite condiments and toppings. Serve immediately.
