# How to Make It:
01 - Preheat the oven to 350°F.
02 - Cook the jumbo pasta shells in a large pot of salted boiling water until al dente (about 2 minutes less than package instructions). Drain and set aside on a tray so they do not stick together.
03 - In a mixing bowl, combine ricotta, squeezed spinach, Parmesan, egg, minced garlic, nutmeg, salt, and pepper. Mix until smooth and set aside.
04 - Heat olive oil in a saucepan over medium heat. Add onion and sauté until soft, about 3 minutes. Add garlic and cook for 1 minute more. Add tomato passata, oregano, basil, salt, and pepper. Simmer gently for 10-15 minutes.
05 - Spread half of the tomato sauce in the bottom of a large baking dish (13x9 inch).
06 - Fill each shell with about 1.5-2 tablespoons of the ricotta-spinach mixture and arrange them in the baking dish.
07 - Spoon the remaining tomato sauce evenly over the stuffed shells.
08 - Sprinkle mozzarella and remaining Parmesan cheese on top.
09 - Cover with foil and bake for 25 minutes.
10 - Remove foil and bake for an additional 10-15 minutes, until the cheese is bubbling and golden.
11 - Let rest for 5 minutes before serving.
