Follow these steps to prepare a delectable Eggplant Rollatini:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C). This ensures that your dish will cook evenly and develop a beautiful golden crust.
2. Prepare the Eggplant: Lightly spray the thinly sliced eggplant with olive oil and arrange them on a baking sheet. Bake for 15 minutes or until they are softened. This step helps the eggplant slices become pliable for rolling.
3. Make the Cheese Filling: In a mixing bowl, combine the ricotta cheese, shredded mozzarella cheese, grated Parmesan cheese, egg, and chopped basil. Season the mixture with salt and pepper to taste. Stir until well blended.
4. Prepare the Baking Dish: Spread a layer of marinara sauce on the bottom of a baking dish. This will prevent the rolls from sticking and infuse them with flavor.
5. Assemble the Rollatini: Place a spoonful of the cheese mixture on one end of each eggplant slice. Carefully roll up the slices and arrange them seam-side down in the prepared baking dish.
6. Add the Final Touch: Pour the remaining marinara sauce over the rolled eggplant slices. Sprinkle extra mozzarella cheese on top for a cheesy finish.
7. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the rolls are bubbly and golden brown. Allow the dish to cool slightly before serving.
