Ensure the green beans are thoroughly dried after rinsing to help the breading adhere better. For a spicier kick, use a hotter Buffalo sauce or add a pinch of cayenne pepper to the bread crumb mixture. If you don't have panko bread crumbs, regular bread crumbs can be used, but panko will provide a crispier texture. These green bean fries are best served immediately while they are still crispy. If you have leftovers, store them in an airtight container in the refrigerator. Reheat in the oven or air fryer to regain some crispness.
