This recipe is my favorite with zucchini, though it also works very well with tomatoes. You could also use different vegetables like eggplant or potatoes. Gratin is just a technique and it translates very well to different foods. Experiment!
4-6 zucchini, sliced
Layer sliced zucchini in a shallow baking dish coated with olive oil. Sprinkle over top with bread crumbs, parmesan, salt, and pepper. Drizzle lightly with olive oil. Bake for 25-30 minutes until golden brown. Serve hot.
*If you use Italian breadcrumbs, you don’t need to add Italian seasoning.
