Pre-heat your air fryer to 400ºF.
Trim off the tough ends of the asparagus. Drizzle with olive oil, toss to coat each spear and season with salt and freshly ground black pepper. Place the asparagus in the air fryer basket and air-fry for 8 to 10 minutes, rotating the spears partway through the cooking process.
Transfer the air-fried asparagus to a serving platter and immediately sprinkle the toasted breadcrumbs on top. Gently toss to coat the asparagus with the crumbs and serve warm or at room temperature.
