# Directions:
01 - Set the oven temperature to 350°F.
02 - Boil salted water in a large pot and cook pasta shells until al dente, approximately two minutes less than package instructions. Drain and lay shells on a tray to prevent sticking.
03 - In a mixing bowl, combine ricotta cheese, squeezed spinach, Parmesan, egg, minced garlic, ground nutmeg, salt, and black pepper. Stir until mixture is smooth.
04 - Heat olive oil in a saucepan over medium heat. Sauté chopped onion until soft, about 3 minutes. Add minced garlic and cook 1 minute more. Incorporate tomato passata, oregano, basil, salt, and pepper. Simmer gently for 10 to 15 minutes.
05 - Spread half of the tomato sauce evenly over the bottom of a large baking dish.
06 - Fill each pasta shell with approximately 1.5 to 2 tablespoons of the ricotta and spinach mixture and arrange them in the baking dish over the sauce.
07 - Pour the remaining tomato sauce evenly over the filled shells. Sprinkle shredded mozzarella and remaining Parmesan cheese on top.
08 - Cover the dish with foil and bake for 25 minutes in the preheated oven.
09 - Remove the foil and continue baking for an additional 10 to 15 minutes until the cheese is melted and golden brown.
10 - Allow the dish to rest for 5 minutes before serving to set.
