In a mixing bowl, add drumsticks, garlic powder, onion powder, chili powder, paprika, ginger, salt, and pepper. Using your clean hands, generously rub the seasoning all over the drumsticks.
Refrigerate to allow the seasonings to penetrate the meat, for at least 30 minutes.
Meanwhile preheat the oven to 350F and line a roasting tin with aluminum foil for easy cleanup, if desired.
Transfer the chicken drumsticks to the prepared roasting tin arranging them on the wire rack with a little space in between.
Bake, in the middle of the oven, for 40 minutes, flipping half time.
When the time is up, remove from the oven and brush each chicken drumstick with BBQ sauce. Return to the oven and bake for 10 minutes, then flip the drumsticks and repeat the process once again.
Serve immediately and enjoy!
