Preheat your air fryer to 390°F (200°C).
Drain and rinse the chickpeas thoroughly. There's no need to dry them completely, although lightly patting them with a paper towel can help create an even crispier texture.
Transfer the chickpeas to a large bowl. Add the olive oil, salt, garlic powder, onion powder, paprika, and cayenne pepper if using. Toss well until every chickpea is evenly coated.
Pour the seasoned chickpeas into the air fryer basket, spreading them into a single layer as much as possible.
Air fry for 12 to 15 minutes, shaking the basket every 4 to 5 minutes to ensure even cooking.
Once the chickpeas are golden brown and crispy, remove them from the air fryer.
Taste and season with additional salt, black pepper, or your favorite seasoning blend if desired.
Allow the chickpeas to cool for a few minutes before serving, as they become even crispier as they cool.
