01 - In a mixing bowl, whisk together the buttermilk, salt, pepper, garlic powder, and paprika until well combined. Add the chicken strips and toss to coat thoroughly. Allow to marinate for at least 10 minutes, or up to 2 hours for deeper flavor penetration.
02 - In a separate shallow bowl, combine the panko breadcrumbs, flour, paprika, onion powder, cayenne pepper if using, and salt. Mix evenly to distribute the seasonings throughout.
03 - Preheat the air fryer to 400°F for 3 minutes to ensure an even cooking environment.
04 - Remove each chicken strip from the marinade, letting any excess drip off. Dredge in the breadcrumb mixture, pressing gently on all sides so the coating adheres firmly to the surface.
05 - Place the coated tenders in a single layer inside the air fryer basket without overcrowding. Lightly spritz the tops with olive oil spray to promote browning and crispness.
06 - Cook at 400°F for 10 to 12 minutes, flipping the tenders halfway through, until the exterior is golden brown and the internal temperature registers 165°F.
07 - Transfer the tenders to a plate and serve immediately with your preferred dipping sauces such as honey mustard or ranch.
