Drain and dry the boiled chickpeas thoroughly with a kitchen towel.

In a bowl, season the chickpeas with olive oil, salt, pepper, and parmesan powder.

Mix well until the chickpeas are evenly coated.

Line the air fryer with parchment paper and spread the chickpeas in a single layer.

Air fry at 200°C (392°F) for 20 minutes.

Shake the basket, then air fry for another 5 minutes until crispy.
