In a shallow dish, mix the panko breadcrumbs with Parmesan cheese.
In a separate bowl, whisk together the eggs and flour until smooth.
Dip each asparagus spear first into the egg mixture, then coat it in the panko-Parmesan blend. Spray with olive oil.
Air Fryer Method:
Arrange the coated asparagus in a single layer in the air fryer basket. Air fry at 380°F for 6-7 minutes, turning halfway through, until golden and tender.
Oven Method:
Preheat your oven to 425°F. Prepare a baking sheet with a light coating of oil. Place the asparagus spears on the sheet, spray them with oil, and bake for 12-14 minutes, flipping halfway, until golden and cooked through.
