Trim off the ends of the zucchini and cut into quarters lengthwise. Place each quarter flat side down, then cut crosswise into 3/4-inch thick half-moons so that you have chunks about 3/4 inch in size. Place in a large mixing bowl.

Drizzle the zucchini with olive oil and toss to coat evenly.

Preheat the air fryer to 200°C (400°F).

Transfer the first batch to a serving plate or a parchment-lined baking sheet if keeping warm in a 93°C (200°F) oven. Repeat with remaining zucchini.
