Slice zucchini then lay out on paper towel that has salt on bottom, salt top of zucchini as well
Cover zucchini with paper towel so there are at least two layers top and bottom
Set something heavy, I used a cookie sheet with a caste iron pan, on top of paper towels
Let zucchini sit for min 10 mins to let salt draw out excess water, pat dry REALLY WELL after! This is how you get the crisp
Bowl 1- egg/egg white mix
Bowl 2- breadcrumbs, parm, seasonings
Start an assembly line dipping zucchini into egg mix first, breadcrumbs second. I used every last drop for 2 whole zucchinis
Lay zucchini on a lightly greased cookie sheet (I used one with a silicone liner to prevent sticking) **to weigh oil on pan set cookie on scale, tare scale, spray 5g on bottom of pan
Add another 5g of cooking spray to top of zucchini; weigh same way as bottom layer
Put in oven for 10-15 mins or until tops are golden brown
Reheat in air fryer to use leftovers and keep the crisp!
