    Classic stuffed shells are a pasta bake casserole made with jumbo shells, ricotta cheese, and marinara sauce. However, I prefer including spinach or ground beef.

    Why You’ll Love This Recipe

    • Spinach is rich in several minerals and it’s so good for you.
    • You can make it ahead of time.
    • Feeds a crowd!
    • It’s delicious, cheesy, and makes the best leftovers!

    Ingredient Notes

    • Jumbo Shells – It’s important to cook them al dente because they will continue cooking in the oven. The package recommended 9 minutes for al dente but I cooked them for 8 minutes.
    • Marinara Sauce – Feel free to use store-bought or homemade.
    • Ricotta Cheese – Although I used ricotta cheese, feel free to use cottage cheese or mascarpone cheese instead. This recipe is so versatile.
    • Mozzarella Cheese – Some people don’t add mozzarella cheese but I think it adds great flavor.
    • Spinach – You can use fresh or frozen spinach, if using frozen, make sure to thaw completely.

    Top Tips For The Perfect Spinach and Ricotta Stuffed Shells

    • I want you to use your favorite sauce for this recipe! If you’re not a fan of marinara sauce, use three-cheese Alfredo sauce, vodka sauce, or your personal favorite!
    • Feel free to include mushrooms, broccoli, kale, or peppers. Just mix it in the ricotta cheese mixture.
    • I’m not a fan of crunchy shells, therefore I don’t bake the shells uncovered for too long. Avoid broiling the shells if you don’t like them crunchy.

    Make Ahead and Storing Leftovers

    If you want to make these spinach and ricotta stuffed shells ahead of time, make them as instructed, but instead of baking, cover it with aluminum foil, and refrigerate. When ready to bake, take it out of the fridge and allow it to sit at room temperature for at least 20 minutes before baking.

    For leftovers, allow them to cool completely then transfer them to an air-tight container and refrigerate for up to 3 days.
