Wash and cut the zucchini into 1/8-inch-thick slices. Pat dry to remove moisture if needed. To get evenly cut slices, use a mandoline.
In a large mixing bowl, add the zucchini, Italian seasoning, garlic powder and salt; mix well. Make sure the seasoning coats each slice of zucchini.
Preheat the air fryer to 400°F. Transfer the zucchini to the air fryer basket and air-fry the zucchini for a total of 25-30 minutes (this will vary by air fryer model). Shake and stir the zucchini every 5 minutes until it's crisp and brown.
1 teaspoon Italian seasoning
1/4 teaspoon garlic powder
1/4 teaspoon salt
Air Fryer: Making zucchini in an air fryer mimics deep frying, but uses hot air to crisp the food instead of oil. The zucchini might not be as crisp as when it is fried, but it still yields great results.
Heat-Resistant Tongs: Since the air fryer gets hot, use a pair of tongs to flip and remove the zucchini rounds from the basket.
Mandoline: A mandoline ensures the slices are evenly cut, which leads to evenly cooked zucchini chips.
