01 - In a mixing bowl, whisk together the buttermilk, salt, black 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 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 evenly to distribute the seasonings throughout the breading.
03 - Set the air fryer to 400°F and preheat for 3 minutes to ensure even cooking and optimal crisping.
04 - Remove each chicken strip from the marinade, allowing the excess buttermilk to drip off. Dredge in the breadcrumb mixture, pressing firmly on all sides so the coating adheres evenly.
05 - Place the coated tenders in a single layer inside the air fryer basket, leaving space between each piece for proper air circulation. Spritz lightly with olive oil spray to promote browning.
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.
07 - Transfer the tenders to a plate and serve immediately while hot, paired with your preferred dipping sauces such as honey mustard or ranch.
