Creating Easy Stuffed Shells is a straightforward process if you follow these steps:

1. Cook Pasta: Begin by boiling the jumbo pasta shells according to package instructions. Drain and set aside to cool.
2. Preheat Oven: Preheat your oven to 375°F (190°C).
3. Prepare Filling: In a large bowl, combine ricotta cheese, ½ cup mozzarella cheese, Parmesan cheese, egg, oregano, garlic powder, salt, and pepper. Mix well until all the ingredients are fully incorporated.
4. Stuff Shells: Take each shell and fill it with a generous portion of the cheese mixture. Place the stuffed shells in a 9×13 inch baking dish.
5. Add Sauce: Pour marinara sauce evenly over the stuffed shells, ensuring they are well-coated.
6. Top with Cheese: Sprinkle the remaining mozzarella cheese on top of the sauce.
7. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 15-20 minutes until cheese is bubbly and golden.

These steps outline the simple process to create a dish that’s both comforting and satisfying!
