Preheat the oven to 425 F and line a baking sheet with foil. Brush or spray the foil with oil or cooking spray.
Cut the zucchini into matchsticks, about 1/4-inch thick
Place the panko breadcrumbs, grated Parmesan, dried parsley, garlic powder, onion powder, salt, and pepper in a shallow dish. Mix them until well combined.
Beat the eggs in a separate shallow dish.
Place the zucchini matchsticks into a large zipper bag along with the flour and shake to coat. Remove the matchsticks shaking off any excess flour.
Dip the matchsticks into the beaten eggs until fully coated, then into the panko/Parmesan mixture to coat fully.
Place them on the baking sheet and bake for 20 mins or until slightly golden brown and crispy.
Make the dipping sauce: whisk together all ingredients in a small bowl until smooth.
