Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil and set aside.
Bring a large pot of salted water to a boil. Cook the jumbo pasta shells according to the package instructions until al dente. Drain and set aside to cool slightly.
In a large mixing bowl, combine the ricotta cheese, 1 cup of shredded mozzarella, 2 tablespoons of Parmesan cheese, the egg, minced garlic, Italian seasoning, chopped spinach, salt, and pepper. Mix well until thoroughly combined.
Spread 1 cup of marinara sauce evenly across the bottom of the prepared baking dish.
Carefully spoon the cheese mixture into each cooked pasta shell, filling generously, and place them open side up in the baking dish.
Pour the remaining 2 cups of marinara sauce over the stuffed shells, covering them completely. Sprinkle the remaining 1 cup of shredded mozzarella and 1 tablespoon of Parmesan over the top.
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Then, remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let the casserole rest for 5 minutes. Garnish with fresh basil leaves, if desired, before serving.
