What Kind of Pasta Shells Should I Use?

Look for jumbo pasta shells — they’re specifically designed to hold hearty fillings like this cheesy spinach mixture. You’ll usually find them in the pasta aisle labeled as “jumbo shells” or “conchiglioni.” Be sure to cook them al dente so they hold their shape while baking and don’t get mushy.

Options for Substitutions

No ricotta? You can swap in cottage cheese for a similar texture with a bit more protein. If you prefer a dairy-free version, try almond-based ricotta or a tofu-cashew blend.

Feel free to switch up the greens — kale or Swiss chard make great alternatives to spinach. For a heartier, meatier version, add some cooked ground turkey or Italian sausage to the filling. You can even play with the sauce — a creamy Alfredo or a roasted red pepper sauce would give this dish a fun twist.

Ingredients for This Spinach and Cheese Stuffed Shells Recipe

• Jumbo Pasta Shells – These large shells are perfect for holding the creamy spinach and cheese filling.
• Ricotta Cheese – Provides a rich, creamy base for the filling. It’s smooth and mild, letting the other ingredients shine.
• Mozzarella Cheese – Melted mozzarella adds stretchiness and that irresistible cheesy pull.
• Parmesan Cheese – Brings a salty, nutty flavor that deepens the overall taste of the dish.
• Frozen Spinach – Easy to use and packed with nutrients. Thawed and squeezed dry to avoid watery filling.
• Egg – Helps bind the cheese and spinach together in the filling.
• Marinara Sauce – A rich, garlicky tomato sauce that coats the shells and keeps them moist while baking.
• Garlic Powder – Adds a layer of savory flavor without having to sauté garlic.
• Salt & Black Pepper – Essential for seasoning and balancing flavors.
• Fresh Basil or Parsley (optional) – For garnish and a burst of fresh, herby finish.

Step 1: Cook the Pasta Shells

Boil a large pot of salted water and cook the jumbo pasta shells just until al dente. You don’t want them too soft since they’ll continue cooking in the oven. Drain and rinse under cool water to stop the cooking and make them easier to handle.

---

Step 2: Prepare the Filling

In a large mixing bowl, combine the ricotta, 1 cup of shredded mozzarella, 1/2 cup of grated Parmesan, thawed and squeezed spinach, the egg, garlic powder, salt, and pepper. Stir until the mixture is evenly combined and creamy.

---

Step 3: Fill the Shells

Spoon the cheese and spinach mixture into each cooked shell. Don’t overfill — about 1 to 2 tablespoons per shell is perfect. Place them open-side up in a baking dish that’s been spread with a layer of marinara sauce.

---

Step 4: Assemble the Dish

Pour more marinara sauce over the filled shells, covering them generously. Sprinkle the remaining mozzarella and Parmesan on top. This will melt into a bubbly, golden topping.

---

Step 5: Bake Until Bubbly

Cover the baking dish with foil and bake in a preheated oven at 375°F (190°C) for about 25 minutes. Then uncover and bake for another 10 minutes until the cheese is melted and slightly golden. Let it rest for 5–10 minutes before serving.

How Long to Prepare the Spinach and Cheese Stuffed Shells

Prep Time: The total prep time is around 25–30 minutes. This includes boiling the pasta, thawing and draining the spinach, mixing the filling, and assembling the shells. It’s straightforward but involves a few steps that are best done in sequence.

Cook Time: Once assembled, the stuffed shells bake for about 35 minutes total — 25 minutes covered, then an additional 10 minutes uncovered to let the cheese melt and brown slightly. Resting them for a few minutes before serving lets the flavors settle.

Tips for Perfect Spinach and Cheese Stuffed Shells

• Drain Spinach Thoroughly: After thawing the spinach, be sure to squeeze out as much liquid as possible. Excess moisture can make the filling watery.
• Don’t Overcook the Shells: Cook them just until al dente. Overcooked shells may tear during stuffing.
• Use a Piping Bag or Spoon: For a neater fill, use a piping bag or zip-top bag with the corner snipped off. A small spoon also works well.
• Layer Sauce Well: Be generous with sauce under and over the shells to keep them moist and flavorful.
• Rest Before Serving: Letting the shells sit for 5–10 minutes after baking helps them hold together better and enhances flavor.

Watch Out for These Mistakes While Cooking

• Using Too Much Filling: Overfilled shells can split or overflow.
• Skipping the Egg: The egg helps bind the filling. Without it, the texture may be too loose.
• Not Enough Sauce: Dry shells result if you skimp on sauce. Always coat both the bottom of the dish and the tops of the shells.
• Baking Without Covering: If you skip covering with foil initially, the cheese may burn before the shells are fully heated through.
• Forgetting to Season: Always taste the filling mixture and adjust seasoning before stuffing.

Storage Instructions

Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven until hot throughout.

Freezing: Assemble the stuffed shells and cover tightly with foil. Freeze unbaked for up to 2 months. When ready to use, bake directly from frozen at 375°F (covered) for about 45–50 minutes, uncovering during the last 10 minutes.

Reheating Tips: Add a splash of water or extra sauce before reheating to prevent drying out. Microwave individual portions or reheat a whole dish covered in the oven.
