Pat drumsticks completely dry with paper towels to remove moisture (key for crispy skin).
Place drumsticks in a bowl, drizzle with olive oil, and coat evenly.
Season with salt, pepper, garlic powder, and smoked paprika (add seasoning under the skin if possible).
Optional: Let rest at room temperature for 15–30 minutes for more even cooking.
Preheat air fryer to 400°F (200°C) for 3–5 minutes.
Arrange drumsticks in a single layer in the basket (do not overcrowd).
Cook for 22–25 minutes, flipping halfway (around 12 minutes).
Check internal temperature; it should reach 165°F (74°C) minimum (175°F for more tender meat).
Remove and rest for 3–4 minutes before serving.
