# How to Make:
01 - Set the oven temperature to 350°F to prepare for baking.
02 - Boil jumbo shells in salted water until just shy of al dente, about 2 minutes less than package instructions. Drain and arrange on a tray to prevent sticking.
03 - Combine ricotta, drained spinach, Parmesan, egg, minced garlic, nutmeg, salt, and pepper in a mixing bowl. Mix thoroughly until smooth.
04 - Heat olive oil over medium heat in a saucepan. Sauté onion until softened, about 3 minutes. Add garlic and cook an additional minute. Stir in tomato passata, oregano, basil, salt, and pepper. Simmer gently for 10 to 15 minutes.
05 - Evenly coat the bottom of a large baking dish with half of the tomato sauce.
06 - Stuff each pasta shell with approximately 1.5 to 2 tablespoons of the ricotta-spinach mixture, arranging them side-by-side in the baking dish.
07 - Pour the remaining tomato sauce over the arranged stuffed shells, ensuring full coverage.
08 - Sprinkle shredded mozzarella and Parmesan evenly over the sauced shells.
09 - Cover the dish with foil and bake for 25 minutes in the preheated oven.
10 - Remove the foil and bake for an additional 10 to 15 minutes, until cheese bubbles and turns golden.
11 - Let rest at room temperature for 5 minutes to set before serving.
