Preheat your oven to 375°F (190°C).
In a baking dish, spread a layer of marinara sauce on the bottom.
Place a layer of ravioli over the sauce, ensuring they are slightly overlapping.
Spread ricotta cheese evenly over the ravioli.
Sprinkle a layer of mozzarella cheese on top of the ricotta.
Repeat the layering process until all ingredients are used, finishing with mozzarella on top.
Drizzle olive oil and sprinkle Italian seasoning over the top layer.
Cover the dish with aluminum foil and bake for 20 minutes.
Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Let it cool for a few minutes before serving. Garnish with fresh basil.
