There are lots of baked zuke recipes on 'Zaar. Here is my take. I only dip a single side so I don't have to worry about flipping them, but you can certainly dip both and flip them during baking. Of course, the amount of seasoning and egg white you use will depend on the size of your zucchini. Sometimes I'll add some grated parmesan or extra cayenne pepper. DH likes to dip these in ketchup.
