Preheat Air Fryer: Preheat your air fryer to 400°F (200°C).

Slice Zucchini: Slice the zucchini into thin circles, about 1/8-inch thick. Thinner slices result in crispier chips but may require batch cooking if the air fryer is small.

Prepare Zucchini Coating: In a large bowl, toss the zucchini slices with olive oil.

In a separate bowl, mix chickpea flour, salt, garlic powder, and black pepper.

Coat Zucchini Slices: Dip each zucchini slice into the flour mixture, coating both sides. Shake off any excess.

Cook Zucchini: Place the coated zucchini slices into the air fryer basket in a single layer, avoiding overlap.

Cook for 10 minutes at 400°F (200°C). Check for doneness and crispiness.

Flip slices and cook for an additional 2-5 minutes until golden and crisp.

Batch Cooking: If cooking in batches, repeat the coating and cooking process for the remaining zucchini slices.

Once all batches are cooked, return all slices to the air fryer and heat for 2 minutes to ensure even warmth.

Serve: Serve the zucchini chips warm as a side dish or with your favorite dip as an appetizer.
