Preheat the oven to 375F.

Grease an 8x11 inch baking pan with butter. Tip over the container with shredded zucchini, and strain excess liquid. Add the egg and egg white, and use a cheese grater to grate about 1 tbs of Parmesan into the zucchini mix. Combine the mixture and season with salt and pepper.

Pour the mixture into the baking pan and spread it out evenly. Sprinkle with the breadcrumbs, and grate Parmesan cheese on top. When done, use a rubber spatula to gently press in the mixture, so that the bread crumbs absorb the liquid.

Cover the baking pan with aluminum foil, and bake for 25 minutes, or until puffed up and bubbly. Uncover, and bake for a further 10-15 minutes, or until golden. Serve immediately.
