Prep the Zucchini: Wash and dry zucchinis. Slice into uniform 3-inch long by 1/2-inch thick batons. Spread on paper towels and pat firmly to remove excess surface moisture (crucial for crunch).
Set Up Breading Station: Set out three shallow dishes. Dish 1: all-purpose flour seasoned with a pinch of salt. Dish 2: eggs beaten with 1 tablespoon water. Dish 3: combine panko breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, Italian seasoning, and smoked paprika.
Standard Breading Method: Dredge each zucchini fry lightly in flour, tap off excess, dip completely into egg wash, then press firmly into the panko-Parmesan mixture until thoroughly coated.
Arrange on Wire Rack: Place a metal baking wire rack over a large baking sheet and spray lightly with oil. Arrange the breaded zucchini fries in a single layer with space between each fry for air circulation.
Lightly Mist with Oil: Mist the tops of the zucchini fries lightly with olive oil or avocado oil spray. This ensures even golden browning.
Bake to Golden Crunch: Bake in a preheated oven at 425°F (220°C) for 20 to 24 minutes until deeply golden, blistered, and shatteringly crispy. (No flipping needed when baked on a wire rack!)
Whip Garlic Herb Dip: While fries bake, whisk mayonnaise, grated garlic, lemon juice, minced fresh dill, and sea salt in a small bowl. Refrigerate until ready to serve.
Season & Serve: Transfer hot fries to a basket, immediately sprinkle with flaky sea salt and fresh chopped parsley, and serve piping hot with the chilled garlic herb dip.
