Make juicy and flavorful BBQ chicken drumsticks in the Ninja Foodi Air Fryer. Season the drumsticks with your favorite BBQ rub or marinade, then place them in the air fryer basket. Cook at a medium-high temperature for about 20-25 minutes, flipping halfway through, until the chicken is cooked through and the skin is crispy. Brush with additional BBQ sauce before serving for extra flavor.
