What Kind of Pasta Shells Should I Use?

For this recipe, you’ll need jumbo pasta shells (also known as conchiglioni). These large shells are perfect for stuffing and hold the creamy spinach and ricotta filling beautifully. Be sure to cook them until they’re al dente—soft enough to be pliable but firm enough to hold their shape during baking. If you overcook them, they can tear when filling, so keep an eye on them while boiling!

If you can’t find jumbo shells, an alternative is manicotti tubes or cannelloni, but the texture and experience of stuffed shells are hard to beat!

Options for Substitutions

If you need to tweak this recipe to fit dietary preferences or use what you have on hand, here are some great swaps:

• Cheese Substitutions – Swap ricotta with cottage cheese for a lighter option, or use vegan ricotta for a dairy-free version.
• Spinach Alternatives – Kale, Swiss chard, or even sautéed mushrooms make great substitutes if you’re out of spinach.
• Sauce Variations – Marinara is classic, but you can use alfredo sauce for a richer, creamier dish or vodka sauce for a tangy twist.
• Pasta Alternative – If you can’t find jumbo shells, try layering the filling between lasagna noodles for a similar effect.
• Added Protein – Mix in cooked ground turkey, sausage, or shredded chicken to the ricotta filling for extra heartiness.

This dish is super flexible, so don’t hesitate to get creative with what you have in your pantry!

Ingredients for Cheesy Spinach Stuffed Shells

Every ingredient in this recipe plays a crucial role in making the dish deliciously creamy, cheesy, and flavorful. Here’s what you’ll need:

• Jumbo Pasta Shells – The perfect vessel to hold the rich and creamy filling. Cook them just until al dente so they don’t fall apart when stuffed.
• Ricotta Cheese – The base of the filling, providing a creamy and slightly sweet texture that pairs perfectly with the spinach.
• Mozzarella Cheese – Used both in the filling and on top for that gooey, melty goodness when baked.
• Parmesan Cheese – Adds a nutty, salty depth of flavor to balance the creaminess of the ricotta.
• Fresh Spinach – Adds a pop of color, nutrition, and a mild earthiness that complements the cheese. You can use frozen spinach, but be sure to drain it well.
• Egg – Helps bind the ricotta filling so it stays creamy but holds its shape inside the shells.
• Garlic – A must-have for an aromatic, savory depth in the filling. Freshly minced garlic works best!
• Italian Seasoning – A blend of oregano, basil, thyme, and rosemary to bring out classic Italian flavors.
• Salt & Black Pepper – Enhances all the flavors in the filling.
• Marinara Sauce – A rich tomato sauce that adds a tangy contrast to the creamy filling. You can use homemade or store-bought.
• Fresh Parsley or Basil – A fresh garnish that adds a burst of color and flavor when serving.

These ingredients come together to create a comforting, cheesy, and flavor-packed dish that everyone will love!

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil and cook the jumbo pasta shells until al dente (usually 1-2 minutes less than the package instructions). Drain them and rinse with cold water to stop the cooking process and prevent them from sticking together.

---

Step 2: Prepare the Filling

In a large mixing bowl, combine the ricotta cheese, 1 cup of mozzarella, Parmesan, chopped spinach, egg, minced garlic, Italian seasoning, salt, and black pepper. Stir everything together until well incorporated. This mixture should be thick and creamy.

---

Step 3: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 375°F (190°C). Spread about 1 cup of marinara sauce evenly on the bottom of a 9×13-inch baking dish. This prevents the shells from sticking and adds extra flavor.

---

Step 4: Stuff the Shells

Using a spoon or a piping bag, carefully fill each cooked pasta shell with the spinach and ricotta mixture. Be gentle to avoid tearing the shells. Arrange them in the baking dish, open side up, so they sit snugly in the sauce.

---

Step 5: Add the Sauce and Cheese

Pour the remaining marinara sauce over the stuffed shells, ensuring each one is lightly coated. Then, sprinkle the remaining mozzarella cheese evenly over the top.

---

Step 6: Bake Until Bubbly

Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for another 10 minutes, or until the cheese is melted and bubbly with a golden brown top.

---

Step 7: Garnish and Serve

Remove from the oven and let the stuffed shells rest for a few minutes. Sprinkle with chopped fresh parsley or basil, then serve warm with garlic bread or a side salad.

---

How Long to Cook Cheesy Spinach Stuffed Shells

The total baking time for this dish is about 35 minutes. Here’s a quick breakdown:

• 25 minutes covered – This helps the shells absorb flavor and prevents the cheese from over-browning too quickly.
• 10 minutes uncovered – This allows the cheese to melt completely and develop that perfect golden-brown, bubbly texture.

Let the dish rest for about 5 minutes after baking to allow the flavors to settle before serving.

Tips for Perfect Cheesy Spinach Stuffed Shells

• Don’t overcook the pasta shells – They should be just al dente so they hold their shape when stuffed and baked.
• Drain spinach well – If using frozen spinach, squeeze out as much liquid as possible to prevent a watery filling.
• Use a piping bag or zip-top bag – Filling the shells is much easier if you use a bag instead of a spoon. Just cut the corner and pipe the mixture in.
• Layer sauce on the bottom – This keeps the shells from drying out and sticking to the baking dish.
• Mix up the cheese – Try adding provolone, fontina, or gouda for a unique twist on flavor.
• Make it ahead – Assemble the dish the night before and refrigerate it, then bake it when you’re ready to serve.
• Let it rest before serving – This helps the cheese set so the shells stay intact when scooped out.

These small tips make a big difference in ensuring your stuffed shells turn out perfectly cheesy and flavorful every time!

Watch Out for These Mistakes While Cooking

Even though Cheesy Spinach Stuffed Shells is a simple dish, a few common mistakes can make or break the final result. Here’s what to avoid:

• Overcooking the pasta – Boil the shells just until al dente. Overcooked shells become too soft and may fall apart when stuffing.
• Not draining the spinach properly – Too much moisture in the filling will make it runny and dilute the flavors. If using frozen spinach, squeeze out excess liquid.
• Skipping the sauce on the bottom – Placing the shells directly in the baking dish without a layer of marinara can lead to sticking and dry shells.
• Overfilling the shells – Stuffing them too much can cause them to burst open while baking. A generous but balanced amount of filling is best.
• Forgetting to cover while baking – Covering for the first 25 minutes ensures the shells don’t dry out before the cheese gets perfectly melted.
• Not letting the dish rest – Give it a few minutes to cool after baking so the flavors meld and the filling sets properly.

By avoiding these mistakes, you’ll end up with a dish that’s creamy, cheesy, and absolutely delicious!
