In a large bowl, combine ground beef, ranch seasoning, shredded cheese, mayonnaise, garlic powder, onion powder, and black pepper. Mix gently until just combined.

Divide the mixture into 4 equal portions and shape into burger patties. Make a small indentation in the center of each patty.

Cook patties on a preheated skillet or grill over medium heat for 4–6 minutes per side, until browned and cooked through.

Toast the buns, assemble the burgers with desired toppings, and serve immediately.
