01 - In a mixing bowl, whisk together the buttermilk, salt, pepper, garlic powder, and paprika until well combined. Add the chicken strips and turn to coat evenly. Allow to marinate for at least 10 minutes, or up to 2 hours in the refrigerator for deeper flavor penetration.
02 - In a shallow dish, combine the panko breadcrumbs, all-purpose flour, paprika, onion powder, cayenne pepper if using, and salt. Mix thoroughly to distribute the seasonings evenly throughout the breading.
03 - Set the air fryer to 400°F and allow it to preheat for 3 minutes.
04 - Remove each chicken strip from the buttermilk marinade, letting the excess drip off. Dredge in the breadcrumb mixture, pressing the coating gently on all sides to ensure it adheres firmly to the surface.
05 - Place the coated tenders in a single layer inside the air fryer basket, leaving space between each piece for proper air circulation. Spritz the tops lightly with olive oil spray.
06 - Cook at 400°F for 10 to 12 minutes, flipping the tenders halfway through the cooking time, until the exterior is golden brown and the internal temperature registers 165°F on a meat thermometer.
07 - Transfer the chicken tenders to a plate and serve immediately while hot, accompanied by your preferred dipping sauces such as honey mustard or ranch.
