Start by patting the chicken drumsticks dry with a paper towel. Toss the drumsticks with kosher salt and baking powder in a large bowl. This helps the skin crisp up beautifully when grilling. Let the chicken rest for about 20 minutes at room temperature while you prepare the dry rub.

Combine the light brown sugar, Italian seasoning, paprika, garlic powder, onion powder, and ground pepper in a small bowl. Stir the ingredients together until evenly mixed.

Drizzle the olive oil over the chicken drumsticks, ensuring each drumstick is lightly coated. Then, sprinkle the dry rub generously over the drumsticks, ensuring every piece is evenly seasoned for maximum flavor.

Preheat your grill to medium heat, around 375°F (190°C). Make sure the grill grates are clean and lightly oiled to prevent sticking.

Place the drumsticks on the grill, spacing them out evenly. Grill the chicken for about 30-35 minutes, turning every 5-7 minutes to cook evenly on all sides. You want the internal temperature to reach 165°F (74°C), and the skin should be golden and crispy.

Once the chicken is cooked, remove the drumsticks from the grill and rest for 5 minutes. This allows the juices to be redistributed, making the chicken extra tender. Serve hot and enjoy!
