Preheat the air fryer: Set it to 400°F (200°C) to ensure crispy, even cooking.

Slice the zucchini: Cut into 3–4-inch sticks, about ½ inch thick. Keep sizes uniform.

Mix the coating: In a shallow dish, stir together Parmesan, breadcrumbs, garlic powder, salt, and pepper.

Beat the egg: In another dish, beat 1 egg until smooth.

Coat the zucchini: Dip each stick in the egg, let the excess drip off, then press into the breadcrumb mixture to fully coat.

Arrange in the basket: Place in a single layer in the air fryer basket. Don’t overcrowd—work in batches if needed.

Air fry until crispy: Cook for 8–10 minutes, flipping halfway through. Add 2 extra minutes for thicker sticks.
