Preheat an outdoor grill for high heat and lightly oil the grate.
Meanwhile, combine ground beef, onion, cheese, egg, onion soup mix, minced garlic, garlic powder, soy sauce, Worcestershire sauce, parsley, basil, oregano, rosemary, salt, and pepper in a large bowl. Use your hands to form the mixture into 4 patties.
Cook patties on the preheated grill until no longer pink in the center and the juices run clear, about 4 to 5 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
