How to make crispy parmesan asparagus sticks
Preheat your oven to 425 f/220 c.
Place a wire rack on top of a baking sheet and coat the rack with a nonstick vegetable oil spray.
Snap off the tough ends of each asparagus spear.
Alternatively, place the spears on a cutting board and slice off the tough root ends. Lightly whisk the egg whites in a small, deep bowl.
