Preheat the air fryer to 375°F (190°C) for 3-5 minutes.
In a small bowl, combine the 2 tablespoons avocado oil, 2 teaspoons smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, and 1/2 teaspoon black pepper to make a marinade.
Pat the 10 chicken drumsticks dry with paper towels and place them in a large bowl.
Pour the marinade over the chicken, tossing to evenly coat each drumstick.
Let the chicken marinate for at least 10 minutes to enhance the flavor.
Arrange the drumsticks in the air fryer basket in a single layer, ensuring they don’t overlap.
Air fry at 375°F (190°C) for 22-25 minutes, flipping halfway, until golden brown and fully cooked.
Transfer the cooked chicken to a large bowl and toss with 1/2 cup BBQ sauce.
Return the coated drumsticks to the air fryer and cook at 400°F for 2-3 minutes to caramelize the sauce.
Once done, serve hot and enjoy your flavorful BBQ chicken drumsticks!
