Making Layered Zucchini Ricotta Melts with Marinara is a delightful process. Just follow these steps, and you'll be on your way to creating a beautiful dish:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Zucchini: Slice the zucchinis into thin rounds using a mandoline or sharp knife. Lay them on paper towels, lightly salting to draw out moisture. Let sit for 10 minutes, then pat dry.
3. Mix Ricotta: In a mixing bowl, combine ricotta cheese, egg, salt, pepper, and Italian seasoning. Stir until everything is well blended.
4. Layer Zucchini: In a baking dish, spread a thin layer of marinara sauce on the bottom.
5. First Layer: Arrange half of the zucchini slices over the marinara. Spread half of the ricotta mixture over the zucchini. Top with one cup of marinara sauce.
6. Second Layer: Repeat the layering process with the remaining zucchini slices, ricotta mixture, and marinara sauce.
7. Add Cheese: Sprinkle the shredded mozzarella cheese evenly on top of the final layer.
8. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
9. Cool: Once baked, remove from the oven and let cool for about 10-15 minutes before slicing.
10. Garnish: Serve warm, garnished with fresh basil leaves.
