Locate the joint between the drumette and the wingette (the flat part of the wings), place the knife, and cut right through to separate the two pieces.
Preheat your smoker to 225℉/107℃. Keeping the lid open until the initial blast of smoke has cleared before closing is highly recommended. Always remember that each smoker is different; follow manufacturer instructions for the best results.
In a small bowl, combine brown sugar, onion, garlic powder, thyme, oregano, sage, ground pepper, cayenne pepper, mustard, paprika, and celery seeds. Add salt if desired.
Wash turkey wings and thoroughly dry them with a paper towel. Discard the paper towel after use.
Place the turkey wings in a large plate or bowl, lightly season with salt, then thoroughly cover with the dry rub.
Place wings directly on grill plates—smoke for 1½-2 hours or until the internal temperature is at least 165°F/75℃.
Remove the wings from the grill and let them rest for 10 minutes before serving.
Serve with BBQ sauce on the side or your preferred dipping sauce. Enjoy!
