Preheat the Air Fryer:

Preheat your air fryer to 400°F (200°C) for about 5 minutes.

Prepare the Drumsticks:

Pat the drumsticks dry with a paper towel to ensure crispy skin.

In a mixing bowl, drizzle the drumsticks with olive oil and toss to coat evenly.

Season the Drumsticks:

Combine garlic powder, smoked paprika, onion powder, salt, pepper, and cayenne (if using) in a small bowl. Sprinkle the seasoning mix over the drumsticks, making sure they’re evenly coated.

Arrange in the Air Fryer:

Place the drumsticks in the air fryer basket in a single layer, ensuring they are not overcrowded for even cooking.

Cook the Drumsticks:

Air fry the drumsticks at 400°F (200°C) for 20–25 minutes, flipping them halfway through cooking.

Use a meat thermometer to check for doneness. The internal temperature should reach 165°F (74°C).

Rest and Serve:

Let the drumsticks rest for 5 minutes before serving. Pair them with your favorite dipping sauce or sides like coleslaw, mashed potatoes, or roasted vegetables.
