Preheat Oven and Prep Zucchini:

1. Preheat your oven to 425°F (220°C).
2. Line a baking sheet with parchment paper or lightly grease it.
3. Cut the zucchini into fries by slicing them lengthwise into sticks about 1/2-inch thick.

Dredge and Coat:

1. Place the flour in a shallow bowl.
2. In another bowl, beat the eggs until smooth.
3. In a third bowl, mix together the panko breadcrumbs, grated Parmesan, garlic powder, salt, and black pepper.
4. Dredge each zucchini stick in flour, tapping off the excess, then dip into the beaten eggs, and finally coat evenly in the breadcrumb mixture.

Bake:

1. Arrange the coated zucchini fries in a single layer on the prepared baking sheet.
2. Lightly drizzle with olive oil or spray with cooking spray to help with crisping.
3. Bake in the preheated oven for 20–25 minutes, flipping halfway through, until the fries are golden and crispy. If desired, transfer the fries to a cooling rack during the last few minutes of baking for extra crispiness.

Garnish and Serve:

1. Remove from the oven and sprinkle with freshly chopped parsley (if using).
2. Serve immediately with your favorite dipping sauce such as marinara or ranch dressing.
