Pat the drumsticks dry with paper towels. Dry skin helps the coating get crisp.
Toss drumsticks with olive oil in a large bowl until they’re lightly coated.
In a small bowl, whisk paprika, garlic powder, onion powder, salt, pepper, and cayenne if using.
Sprinkle the spice mix over the drumsticks. Toss again to coat evenly.
Preheat the air fryer to 400°F (200°C) for about 3 minutes.
Arrange the drumsticks in a single layer in the air fryer basket. Don't overcrowd; they need space to crisp.
Cook for 10 minutes, then flip and cook another 8–10 minutes, until the internal temperature hits 165°F (74°C) and the skin is crispy.
If the skin isn’t as crisp as you’d like, cook for 2–3 more minutes, checking often.
Let rest for a couple of minutes before serving. That helps the juices settle and keeps the meat tender.
