Set aside 1/4 cup of sauce for later. Add chicken tenders to the sauce making sure they are completely covered.
Allow to soak in marinade/sauce for 15 minutes. Preheat air fryer to 400F for 5 minutes once they're marinated. Spray basket and lay pieces inside allowing excess sauce to drip off before laying in in a single layer.
Air fry for 10 minutes. Flip tenders over and air fry for an additional 4-6 minutes or until internal temperature reaches 160 degrees in the middle. (timing will depend on how thick your meat is)
Brush with remaining BBQ sauce prior to serving.
