Pat your chicken drumsticks completely dry with paper towels, removing any excess moisture from packaging. This ensures the dry rub adheres properly and creates better caramelization during grilling rather than steaming.
Combine all dry spices in a large bowl: smoked paprika, brown sugar, garlic powder, onion powder, black pepper, kosher salt, chili powder, and cayenne pepper. Stir thoroughly until completely blended, breaking up any brown sugar lumps with the back of your spoon.
In a separate bowl, whisk together olive oil, apple cider vinegar, Worcestershire sauce, mustard powder, liquid smoke, and minced garlic until the marinade emulsifies. This wet component penetrates the meat while the dry rub creates that signature exterior crust.
Toss drumsticks with the spice mixture first, coating every surface thoroughly, then drizzle the wet marinade over everything and massage gently into the meat. Let this marinate for just 10 minutes while you preheat your grill—smoky grilled chicken drumsticks crowd recipe achieves peak flavor even with minimal marinating time thanks to the potent spice blend.
Preheat your grill to medium-high heat (around 400°F). Oil the grates to prevent sticking, then arrange drumsticks directly over heat without crowding them.
Grill for 22-25 minutes total, rotating every 6 minutes to ensure even cooking and prevent flare-ups from dripping marinades. Drumsticks are done when the internal temperature reaches 165°F at the thickest part near the bone.
During the final 2 minutes of grilling, brush each drumstick generously with BBQ sauce and let it caramelize slightly. This adds a beautiful glossy finish and enhances the smoky flavor profile.
Transfer finished drumsticks to a serving platter and let rest for 3-4 minutes before serving, allowing juices to redistribute throughout the meat for maximum tenderness.
