The secret to making air fryer zucchini super crispy is a generous amount of olive oil in the breading. The oil helps to mimic the same crunchy crust you’d get from deep-frying, but without the mess. We like to serve fried zucchini with warm marinara sauce, but these bites would be equally delicious (and a bit more indulgent) dipped in creamy ranch dressing or your favorite aioli.
