Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone mat.
Prepare the zucchini: Cut the zucchinis into wedges. You can slice them into rounds, but wedges work best for a crispy texture.
Make the coating: In a shallow bowl, combine the flour, breadcrumbs, nutritional yeast, garlic powder, onion powder, paprika, salt, and pepper.
Prepare the dipping station: In another shallow bowl, pour the plant-based milk.
Coat the zucchini: Dip each zucchini wedge into the plant-based milk, ensuring it's fully coated. Then roll it in the breadcrumb mixture, pressing lightly to ensure it sticks.
Arrange on the baking sheet: Place the coated zucchini wedges in a single layer on the baking sheet. Lightly spray them with olive oil to help them crisp up in the oven.
Bake for 20-25 minutes, flipping halfway through, until the zucchini is golden brown and crispy on the outside.
Serve: Remove from the oven and serve immediately with your favorite dipping sauce (like vegan ranch or marinara).
