In a large mixing bowl, combine the ground beef, dry ranch seasoning, bacon bits, shredded cheddar, green onions, and Worcestershire sauce.

Gently mix by hand until the ingredients are just incorporated, being careful not to overwork the meat.

Divide the mixture into 4 equal portions and shape into patties approximately 0.75-inch thick.

Preheat a grill or cast-iron skillet over medium-high heat.

Cook the patties for 4 to 5 minutes per side until the internal temperature reaches 160°F (71°C).

Spread butter on the cut sides of the buns and toast on the heat source for 30 to 60 seconds until golden brown.

Assemble the burgers by placing patties on the bottom buns and topping with lettuce, tomato, and the top bun.
