Preheat an outdoor grill for medium-high heat, and lightly oil the grate.
Knead together the turkey, ranch mix, egg, garlic, Worcestershire sauce, seasoned salt, and pepper in a bowl until evenly combined; divide into 4 equal portions and form into patties.
Cook on the preheated grill about 5 minutes per side for well done. An instant-read thermometer inserted into the center should read 165 degrees F (74 degrees C).
