Prep the Zucchini:

Slice zucchini into even rounds, about ¼ inch thick. Pat dry with a paper towel to remove excess moisture.

Set Up Coating Station:

Place the beaten egg in one shallow bowl.

In another bowl, mix breadcrumbs, Parmesan, garlic powder, Italian seasoning, salt, and pepper.

Coat the Zucchini:

Dip each slice into the egg, letting excess drip off.

Dredge in the breadcrumb mixture, pressing gently to coat both sides.

Air Fry:

Preheat air fryer to 375°F (190°C) if required by your model.

Lightly spray the air fryer basket with olive oil spray.

Place coated zucchini slices in a single layer (you may need to cook in batches).

Spray tops lightly with oil.

Cook Time:

Air fry for 8–10 minutes, flipping halfway, until golden and crispy.

Serve:

Enjoy immediately with marinara, ranch, or your favorite dipping sauce.
