Preheat Oven: Set your oven to 425°F. Place a wire rack on a baking sheet and coat it with nonstick cooking spray.

Prepare Breading Stations: In one shallow dish, lightly beat the egg whites. In another dish, combine the panko breadcrumbs, flour, Parmesan cheese, salt, and black pepper.

Coat Asparagus: Dip each asparagus spear into the egg whites, ensuring it’s fully coated. Then roll it in the breadcrumb mixture, pressing gently to adhere. Repeat if needed for a thicker coating.

Arrange on Rack: Place the coated asparagus spears on the prepared wire rack in a single layer, making sure they don’t touch.

Bake: Bake for 15 minutes, or until the coating is golden brown and crispy.

Serve: Remove from oven and let cool slightly. Serve warm as a side dish or appetizer.
