01 - In a mixing bowl, whisk together the buttermilk, salt, black 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 so the cooking chamber reaches the proper temperature.
04 - Remove each chicken strip from the buttermilk marinade, letting the excess drip off. Press each strip firmly into the breadcrumb mixture, ensuring an even and complete coating on all sides.
05 - Place the breaded tenders in a single layer inside the air fryer basket, leaving space between each piece for proper air circulation. Lightly spritz the tops 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. The tenders are done when the exterior is golden brown and crisp, and the internal temperature reaches 165°F.
07 - Transfer the tenders to a plate and serve immediately while hot, accompanied by your preferred dipping sauces such as honey mustard or ranch.
