Preheat the oven: Begin by preheating your oven to 425°F (220°C). This high temperature will ensure that your zucchini fries become crispy and golden without the need for frying.
Prepare the zucchinis: Wash the zucchinis thoroughly. Cut off both ends and slice them into strips, similar to the size and shape of regular French fries. Aim for about 1/2-inch thick strips for the best texture.
Set up a breading station: In a shallow bowl, beat the egg. In another shallow bowl, combine the breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, salt, and pepper. Mix everything well.
Coat the zucchini fries: Dip each zucchini strip into the egg mixture, allowing any excess egg to drip off. Then, coat the zucchini in the breadcrumb and Parmesan mixture, pressing gently to ensure it sticks. Place the coated zucchini fries on a baking sheet lined with parchment paper for easy cleanup.
Spray with olive oil: Lightly spray the coated zucchini fries with olive oil to help them crisp up in the oven.
Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the fries are golden brown and crispy. Make sure to flip them halfway through the baking time for even crispiness on both sides.
Serve: Once your zucchini fries are done, remove them from the oven and serve immediately. Pair them with a delicious dipping sauce like marinara, ranch, or garlic aioli.
