Preheat the oven to 425°F (220°C), line a large baking sheet with parchment, and lightly brush the surface with olive oil so the fries brown more evenly.
Trim the zucchini and cut each one into thick fry-shaped sticks, trying to keep the pieces similar in size so they finish cooking at roughly the same time.
Place the flour in one shallow bowl, whisk the eggs in another, and combine panko, Parmesan, garlic powder, Italian seasoning, and salt in a third bowl.
Coat each zucchini stick lightly with flour, dip it into the beaten egg, then press it gently into the breadcrumb mixture until all sides are evenly covered.
Arrange the coated zucchini in a single layer on the prepared pan, leaving a small amount of space between each piece to encourage crisp edges.
Bake for about 12 minutes, carefully turn each fry, and continue baking for another 8–10 minutes until deeply golden and tender inside.
Let the fries rest for 2–3 minutes before serving with marinara sauce, ranch dressing, or a simple garlic yogurt dip.
