In a large bowl, combine the salt, pepper, smoked paprika, onion powder, garlic powder, and rosemary. Whisk the ingredients together until they’re well mixed
Remove the chicken from the package and pat it dry with a paper towel to help the seasoning stick to the skin. Place the chicken pieces in the bowl and toss to coat each drumstick in seasoning.
Then, drizzle the chicken drumsticks with avocado oil and brush the oil over each piece to ensure all sides are evenly coated.
Place the seasoned drumsticks in the air fryer basket in a single layer, leaving space between each piece.
Cook the chicken at 380 degrees Fahrenheit for 20 to 25 minutes, flipping the drumsticks halfway through. Check the internal temperature with a meat thermometer. It should reach 165°F to ensure it is fully cooked.
When the chicken is finished cooking, please remove it from the air fryer basket and let the pieces rest for five minutes before serving.
