Cut ends off zucchini and slice into 1/2" dials. Thinner they are the crispier they will get so thickness is up to you. This is what we like. Preheat air fryer to 350 degrees while you're preparing these.
Lay pieces on paper towels and press gently to remove excess moisture on the outside of your pieces. In a bowl whisk your egg. On a plate add your Panko and seasoning, mix so it is combined.
Dip zucchini pieces one at a time into egg, then coat all sides with bread crumb mixture and when air fryer is preheated add them in one layer to your trivet inside your machine (if you have a trivet).
Once trivet is loaded up with pieces that aren't overlapping spray all of them with olive oil. Then close air crisp lid and continue cooking at 350 degrees for 13 minutes total, flipping after minute 10. (add more minutes for more crispy outsides)
If your dials are small you could do 10 minutes total flipping after 8 minutes.
Remove and enjoy immediately, then add another batch!
