Wash the zucchini thoroughly under running water to remove any dirt or pesticides.

Using a sharp knife, slice the zucchini into thin rounds, about ⅛ inch thick. This thickness ensures they become crispy in the air fryer.

Place the sliced zucchini on a paper towel and sprinkle lightly with salt. Let them sit for about 10 minutes to draw out excess moisture. This step is crucial for achieving crispy chips.

After 10 minutes, pat the zucchini slices dry with another paper towel to remove excess moisture and salt.

In a mixing bowl, combine the dried zucchini slices with olive oil, sea salt, garlic powder, onion powder, and black pepper. Toss gently to ensure all slices are evenly coated.

If using, add the grated parmesan cheese and toss again until the zucchini slices are well coated.

Preheat your air fryer to 375°F (190°C) for about 5 minutes. Preheating helps achieve a crispy texture.

Arrange the zucchini slices in a single layer in the air fryer basket. Avoid overcrowding to ensure even cooking. You may need to do this in batches depending on the size of your air fryer.

Air fry the zucchini slices for 10-15 minutes, shaking the basket halfway through to ensure even cooking. Keep an eye on them towards the end to prevent burning. They should be golden brown and crispy.

Once cooked, remove the zucchini chips from the air fryer and let them cool for a couple of minutes. They will continue to crisp up as they cool.

Serve immediately as a snack or side dish. Enjoy your healthy air fryer zucchini chips!
