01 - Lay zucchini slices on paper towels, sprinkle evenly with kosher salt, and let sit for 10 minutes to extract moisture, then pat dry.

03 - Coat each zucchini slice first in flour, then dip into eggs, and finally cover thoroughly with the panko mixture.
04 - Place the coated zucchini slices in a single layer in the air fryer basket and lightly spray them with olive oil.
05 - Air fry at 400°F for 10 to 12 minutes, flipping halfway through, until the chips turn golden brown and crisp.

07 - Plate hot zucchini chips alongside the ranch dip for dipping.
