Preheat the air fryer to 400°F (200°C).
Cut the zucchinis into fry-shaped sticks.
In a bowl, mix breadcrumbs, parmesan, salt, and pepper.
Dip each zucchini stick into the beaten egg, then coat with the breadcrumb mixture.
Arrange coated zucchini in a single layer in the air fryer basket. Spray lightly with cooking spray.
Air fry for 8 to 10 minutes until golden and crisp, flipping halfway through.
