Slice the zucchinis into strips about 3 inches long and 1/2 inch thick.
In a shallow bowl, combine breadcrumbs, Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper.
In another bowl, whisk together the egg and water.
Dip zucchini strips in the egg mixture, then coat with the breadcrumb mixture, pressing gently to adhere.
Lightly spray air fryer basket with olive oil spray. Arrange zucchini fries in a single layer, being careful not to overcrowd.
Air fry at 400°F for 10-12 minutes, turning halfway through, until golden brown.
