1. Preheat the oven to 350 degrees F. Grease an oven safe 9×13 baking dish with butter or cooking spray.
2. Lay half of the zucchini slices into the baking dish in a single layer. Season with salt and pepper, to taste.
3. Cover the zucchini with just enough marinara to cover all of the slices.
4. Repeat the layers with the remaining zucchini, marinara, and cheddar. You may not use all of the marinara sauce.
5. Top the final layer of cheese with the Italian seasoning.
6. Bake for 35 to 40 minutes, until the cheese is melted and slightly browned.
Allow the baked dish to cool slightly before slicing and serving.
