Preheat your oven to 375°F (190°C).

Trim the ends off zucchinis and slice them lengthwise into thin strips, about 1/4 inch thick. Lay the zucchini strips on a clean kitchen towel to drain excess moisture.

In a mixing bowl, combine ricotta cheese, mozzarella, parmesan, and egg. Season with salt and pepper, then stir until blended.

Spread a generous layer of marinara sauce in the bottom of a baking dish.

Take a zucchini strip and place a spoonful of the cheese mixture at one end. Roll it toward the other end, tucking in the filling. Place seam-side down in the dish.

Pour remaining marinara sauce over the rolls and sprinkle shredded mozzarella cheese on top.

Bake for about 25-30 minutes until cheese is bubbly and golden brown.

Let cool for a few minutes, then garnish with fresh basil before serving.
