Ingredients for Cheesy Spinach Stuffed Shells

Gathering these simple ingredients is the first step to creating a truly wonderful spinach stuffed shells recipe. You’ll need 20 jumbo pasta shells, cooked al dente. For the creamy heart of this dish, we’ll use 1 1/2 cups ricotta cheese, which provides that classic, luxurious texture. We’re also adding 1 cup shredded mozzarella cheese, plus more for topping, for that irresistible cheesy pull. Don’t forget 1/2 cup grated Parmesan cheese for a salty, nutty depth. A single large egg acts as a binder for our filling. To infuse flavor, we’ll use 1 teaspoon garlic powder and 1 teaspoon onion powder, seasoned with salt and pepper to taste. Freshness comes from 2 cups fresh spinach, chopped (or 1 cup frozen spinach, thawed and drained – make sure to squeeze out excess water!). Finally, we’ll need 3 cups marinara sauce to coat everything beautifully, with optional fresh basil and red pepper flakes for garnish. This combination ensures you get those perfect, creamy spinach ricotta shells.

How to Make Cheesy Spinach Stuffed Shells

Step 1: Let’s get started by preheating your oven to 350°F (175°C). This ensures everything bakes evenly and the cheese gets perfectly melty.
Step 2: Bring a large pot of generously salted water to a rolling boil. Carefully add your 20 jumbo pasta shells and cook them according to the package directions until they are just al dente – you don’t want them mushy! Once cooked, drain them gently and set them aside.
Step 3: Now, let’s create that luscious filling. In a large bowl, combine the 1 1/2 cups ricotta cheese, the chopped or thawed and squeezed 2 cups fresh spinach, 1 cup shredded mozzarella cheese, 1/2 cup grated Parmesan cheese, the large egg, 1 teaspoon garlic powder, and 1 teaspoon onion powder. Season with salt and pepper to taste. Mix everything together until it’s well combined and looks wonderfully creamy. This is how to make cheesy spinach shells truly special.
Step 4: Grab your 9×13-inch baking dish. Spread a thin, even layer of about 1 cup of marinara sauce across the bottom. This prevents the shells from sticking and adds a delicious base layer.
Step 5: Carefully spoon the cheesy spinach mixture into each of the cooked jumbo shells. I like to use a spoon or even a small piping bag for this step – it makes it so much easier! Arrange the stuffed shells snugly in the prepared baking dish.
Step 6: Pour the remaining 2 cups of marinara sauce evenly over the stuffed shells, making sure to coat them nicely. Then, sprinkle that extra shredded mozzarella cheese generously over the top for that golden, bubbly finish.
Step 7: Cover the baking dish tightly with aluminum foil. Bake in your preheated oven for 25 minutes. This steaming time helps the flavors meld beautifully.
Step 8: After 25 minutes, carefully remove the aluminum foil. Pop the dish back into the oven for another 10 minutes, or until the cheese on top is melted, bubbly, and has those lovely golden-brown spots. The aroma at this stage is incredible!
Step 9: Once it’s out of the oven, let your masterpiece rest for a few minutes before serving. This allows the sauce to thicken slightly. Garnish with fresh basil or a pinch of red pepper flakes if you like a little heat. Enjoy your delicious cheesy spinach stuffed shells!

Pro Tips for the Best Cheesy Spinach Stuffed Shells

Want to elevate your cheesy spinach stuffed shells? Here are a few tricks I’ve picked up that make a big difference:

Always cook your jumbo shells until they’re just al dente. They’ll continue to cook in the oven, and you don’t want them to fall apart.
Make sure to really squeeze out the moisture from your spinach, especially if you’re using frozen. Excess water can make the filling runny.
Don’t be shy with the marinara sauce! Covering the shells completely helps them steam and stay tender.
For an extra layer of flavor, consider adding a pinch of nutmeg to the ricotta mixture. It complements the spinach beautifully.
