Pat dry the chicken drumsticks using paper towels to remove any excess moisture. This will help the skin to become crispy.
Combine oil, smoked paprika, onion powder, garlic powder, dried rosemary, salt, and pepper in a mixing bowl. Add the chicken drumsticks to it. Mix well, making sure all the chicken pieces are well coated.
Place the seasoned chicken drumsticks in the air fryer basket in a single layer, leaving some space between them for even cooking.
Cook the drumsticks in the air fryer at 380℉ for 20-25 minutes, flipping halfway through. The internal temperature of the chicken should reach 165℉ to ensure they are fully cooked.
Once cooked, remove the drumsticks from the air fryer and let them rest for a few minutes before serving.
Notes
Before seasoning, pat the drumsticks dry with paper towels. This helps the skin become crispy during cooking by removing excess moisture.
Arrange the drumsticks in a single layer in the air fryer basket to achieve optimal crispiness. Overcrowding can lead to uneven cooking and soggy skin, so cook in batches if necessary.
