Ingredients for the Spinach and Cheese Stuffed Shells

Each ingredient in this dish plays a role in building flavor and texture that balances comfort with a touch of elegance.

• Jumbo pasta shells – The perfect vessel to hold all that creamy filling. Make sure they’re cooked al dente so they don’t fall apart when stuffing.
• Ricotta cheese – Provides the smooth, creamy base of the filling. It’s mild and rich, absorbing seasoning beautifully.
• Mozzarella cheese – Melts beautifully for that ooey-gooey, stringy texture we all crave.
• Parmesan cheese – Adds a salty, nutty depth that sharpens the overall flavor.
• Frozen chopped spinach – Thawed and squeezed dry, it adds a wholesome, earthy bite that pairs perfectly with the cheese.
• Egg – Helps bind the cheese filling together so it stays put inside each shell.
• Garlic (minced) – Brings a warm, aromatic base note to the filling.
• Italian seasoning – Infuses the dish with classic herb flavor in one easy scoop.
• Marinara sauce – Lush, tangy, and essential. It coats the shells and brings it all together.
• Salt & black pepper – Enhances every ingredient and balances the richness of the cheese.

How To Make the Spinach and Cheese Stuffed Shells

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Cook the jumbo shells until al dente (about 9 minutes). Drain and rinse with cold water to stop the cooking. Set them aside on a baking sheet so they don’t stick together.

Step 2: Prepare the Filling

In a large mixing bowl, combine ricotta, spinach (thawed and squeezed dry), half of the shredded mozzarella, Parmesan, egg, minced garlic, Italian seasoning, salt, and pepper. Mix until everything is well incorporated.

Step 3: Fill the Shells

Using a spoon or a piping bag, fill each pasta shell with the spinach and cheese mixture. Take care not to overstuff to prevent tearing.

Step 4: Assemble the Dish

Preheat your oven to 375°F (190°C). Spread a layer of marinara sauce on the bottom of a 9×13 baking dish. Arrange the filled shells in a single layer. Pour remaining marinara over the top and sprinkle with the remaining mozzarella.

Step 5: Bake to Perfection

Cover the dish with foil and bake for 25 minutes. Remove foil and bake an additional 10 minutes, until the cheese is bubbling and golden in spots. Let it rest for 5-10 minutes before serving.

Serving and Storing Spinach and Cheese Stuffed Shells

These stuffed shells are best served warm, right out of the oven, when the cheese is perfectly melty and the sauce is bubbling. Pair them with garlic bread, a crisp green salad, or roasted vegetables for a complete Italian-inspired dinner. A sprinkle of fresh basil or extra Parmesan on top just before serving adds a fresh finish.

Leftovers store beautifully, making this a great make-ahead or meal-prep option. Store in an airtight container in the refrigerator for up to 4 days. To reheat, cover with foil and bake at 350°F for 15–20 minutes or microwave individual portions until heated through. You can also freeze the shells—uncooked or cooked—for up to 2 months. Just thaw overnight in the fridge before baking or reheating.

Frequently Asked Questions

How do I keep the shells from tearing while stuffing?

Be sure to cook the shells al dente and rinse them with cold water to stop the cooking process. Let them cool slightly before stuffing, and use a piping bag or small spoon to gently fill each shell.

Can I use fresh spinach instead of frozen?

Yes! Just sauté fresh spinach until wilted and squeeze out as much moisture as possible before adding it to the filling.

What marinara sauce is best for this recipe?

Use your favorite store-bought marinara or a homemade version. A sauce with a little garlic and basil pairs especially well with the ricotta-spinach filling.

Can I make this dish ahead of time?

Absolutely. You can assemble the dish up to 24 hours in advance and keep it in the fridge until ready to bake. It also freezes well for future meals.

Can I add meat to this recipe?

Definitely! Add cooked Italian sausage, ground beef, or even shredded rotisserie chicken to the ricotta filling for a meaty twist.

What if I don’t have ricotta cheese?

You can substitute cottage cheese or a mix of cream cheese and Parmesan, though the texture and flavor will vary slightly.
