Slice the ends of the zucchini off, then slice the zucchini in half, and then into smaller sticks (approximately ½" thick). Once the zucchini is cut, sprinkle salt to wick out any moisture, then let sit for 10 minutes.
Whisk the eggs in a large bowl, and combine the breadcrumbs with the parmesan cheese and garlic powder. Pour the breadcrumb mixture onto a large plate.
Dip the zucchini into the egg.
Let the egg drip a little from the zucchini, then pat directly into the breadcrumb. Repeat until all the zucchini has been breaded.
Add to the air fryer, then spray with some nonstick oil spray. Fry at 375º for 12-13 minutes.
Notes
You don't need to drown the zucchini in the egg dredge before breading it. It will become too soggy and the breadcrumb won't stick well. I suggest a quick dip and then pat directly into the breadcrumb.Use your fingers to pick up the zucchini instead of tongs or a fork. I found that using my fingers was a little bit better at keeping the breading on the zucchini, and if I used something else (like tongs) the breading fell off.Remember to SALT the zucchini and let sit for a few minutes to help wick the moisture out from the squash. The moisture will make the zucchini soggy.
