Preheat the air fryer to 400°F (200°C) for a few minutes while you prep. Yes, preheating helps things crisp up faster.
Toss the chicken pieces with olive oil until evenly coated.
In a bowl, mix breadcrumbs, Parmesan, garlic powder, paprika, salt, and pepper.
Roll each chicken piece in the crumb mixture, pressing gently so it sticks.
Place coated bites in a single layer in the air fryer basket. Don’t overcrowd—give them space to crisp.
Cook 8–10 minutes, flipping halfway, until the coating is golden and the chicken reaches 165°F (74°C).
If you like extra crisp, cook 2–3 minutes more in small batches. Let rest a minute before diving in.
