01 - Preheat oven to 425°F and line a baking sheet with parchment paper or lightly grease with oil.
02 - Slice zucchini into uniform sticks, about 3 inches long and 1/2 inch thick for even cooking.
03 - In a shallow bowl, whisk eggs until well blended and smooth.
04 - Combine grated Parmesan cheese, breadcrumbs, Cajun seasoning, garlic powder, smoked paprika, salt, and pepper in a separate mixing bowl.
05 - Dip each zucchini stick first into the egg mixture, then coat completely with the cheese and breadcrumb mixture, pressing gently for adhesion.
06 - Place coated zucchini sticks in a single layer on the prepared baking sheet, spacing them evenly.
07 - Bake for 18 to 20 minutes, flipping the sticks midway through, until golden brown and crisp.
08 - Sprinkle with chopped parsley and serve warm with ranch or blue cheese dressing for dipping.
