Preheat oven to 450°F and line a baking sheet with parchment paper.
Set up a breading station with three shallow dishes: In the first dish, place the flour seasoned with salt and pepper; in the second dish, beat the eggs with salt and pepper; combine Panko, breadcrumbs, cheese, lemon zest and parsley in the third. Pass the asparagus spears first through the flour then egg and lastly coat in breadcrumbs. Line the spears up on the parchment-covered baking sheet and spray with olive oil cooking spray to lightly coat. Transfer pan to oven and cook until golden and crisp, about 7-8 minutes.
