The best way to make Stuffed Shells is with both cheese and meat.
How to Make Stuffed Shells
Make Sauce: Brown beef and sausage. I also like to pulse the meat in a food processor a few times to get it finely ground. Then add the rest of the sauce ingredients and simmer.
Combine Fill cooked pasta shells according to package instructions then drain and lay out on a large baking sheet so they can cool and not stick together. In a bowl, combine ricotta, egg, 1 cup mozzarella, and 1/3 cup parmesan cheese. Spread 1 cup of the meat sauce in the bottom of a 9×13″baking dish. Carefully stuff each cooked shell with a small amount of ricotta mixture and a spoonful of meat mixture then place face up in the baking dish.

Bake: Sprinkle the easy stuffed shells with the rest of the mozzarella and parmesan cheeses. Bake at 350 degrees F for 25-30 minutes.

Make Ahead and Freezing Instructions
To Make Ahead: This entire stuffed shells recipe can be prepped and assembled up to a day ahead of time, stored in the fridge.To Freeze: This is one of my favorite freezer meals! Assemble in a freezer safe or disposable aluminum pan. Cover with a double layer of aluminum foil. Freeze for up to 3 months. Thaw overnight in the fridge. Bake covered, for 45 minutes, then uncovered for 15-20 minutes or until hot and bubbly.
