Wash and dry each zucchini. Then, slice thinly, no more than ¼ of an inch in thickness.

Place them in a medium bowl and toss with olive oil until lightly coated. Season with kosher salt and black pepper.

Lay the zucchini pieces flat in a single layer in the air fryer basket. Do not stack or overlap.

Air fry at 400 degrees F for 8-10 minutes, shaking halfway through cooking. Adjust time for desired crispness.
