Wash the two zucchini and trim away both ends, leaving skin on. Cut each one in half, length-wise. Cut each half into ½” wedges. Trim away the seeds from each wedge and discard. If you use a large zucchini, cut it in half cross-wise first, to create two pieces.
Preheat the oven to 425°F. Place a rimmed sheet pan on the center rack of the oven.
Prepare the breading station: in a medium bowl place the flour, in the second (deep plate) add the egg and beat it with one tablespoon of water, and, in a third dish combine the bread crumbs with the cheese, the salt and pepper.
Working with three or four pieces at a time, coat each wedge well with the flour, dip it in the egg mixture (allowing excess liquid to drip off), then coat it evenly with the breadcrumbs, pressing them to adhere. Place the breaded wedges on a platter (at this point you can refrigerate them until you are ready to bake).
Remove the preheated sheet pan from the oven. Carefully pour the oil over the sheet and tilt to coat evenly. Lay the wedges on the hot sheet pan in a single layer. Bake them for about 12 minutes or until golden brown and crisp on one side (baking time will depend on the size of the zucchini). With the help of a spatula, gently flip them and bake for another 8 more minutes or so.
Remove from the oven and serve the zucchini fries warm with some tzatziki.
