Use a mandoline to slice zucchini into 1/8 inch thick slices.

Pat any excess moisture off of the zucchini slices with a paper towel.

Preheat your air fryer to 325 degrees F (162 degrees C).

In a medium bowl, combine the zucchini slices, olive oil, sea salt, and pepper. Toss until all slices are coated.

Place the zucchini chips in the air fryer in a single layer. Cook for 8-12 minutes, flipping halfway through. Check at the 8-minute mark and remove any slices that are browning/crisping. Continue to check every couple of minutes until all slices are done. Repeat with all the zucchini slices.

Let the air fryer zucchini chips cool to crisp up more.
