Season the breadcrumbs well, don’t skimp on the salt as that makes a huge difference.
Buttermilk can be substituted with plain yogurt diluted with a splash of water.
Use any vinegar-based hot sauce such as Frank’s, Louisiana, or sriracha. Make sure that the chicken is well coated in the breadcrumbs/panko.
The Air Fryer won’t turn the breading golden and dark as it air fries, but applying the sauce will.
When making the Nashville sauce, don’t omit the brown sugar as it adds SO much to the flavor!
Baste the chicken with the Nashville sauce while the chicken is still hot. If you wait until everything has cooled down, you might end up with greasy chicken.
Keep the chicken warm in the oven if you’re air frying chicken in batches (I could only fit 6 tenders at a time). But make sure you’re using an oven-proof wire rack that does not melt in the oven.
