What Kind of Pasta Shells Should I Use?

Look for jumbo pasta shells at the store—they’re specifically designed to be filled. The large size makes them perfect for holding generous scoops of the spinach and cheese mixture. Be careful not to overcook them during boiling; you want them al dente so they hold their shape during baking.

Options for Substitutions

You can easily make this recipe your own with a few simple swaps:

• Cheese: Try cottage cheese instead of ricotta if you want a lighter texture. Fontina or provolone can replace mozzarella for a slightly different flavor.
• Greens: Swap spinach with kale or Swiss chard. Just make sure to cook and drain them well.
• Sauce: Marinara is classic, but a roasted red pepper sauce or even a creamy béchamel would add a unique twist.
• Protein: Add cooked crumbled Italian sausage or ground turkey into the cheese mixture if you’re craving meat.

Ingredients for This Spinach and Cheese Stuffed Shells Recipe

• Jumbo Pasta Shells: These are the foundation of the dish and are perfect for holding the cheesy spinach filling.
• Ricotta Cheese: Soft and creamy, ricotta gives the filling a smooth, rich texture.
• Mozzarella Cheese: Provides that melty, stringy cheese pull we all love. Use part-skim or whole milk depending on preference.
• Parmesan Cheese: Adds sharpness and depth to the cheese blend, as well as a crisp topping when baked.
• Frozen Spinach: Easy and convenient, just make sure to thaw and squeeze out excess water.
• Egg: Helps bind the cheese and spinach mixture so it stays together in the shells.
• Garlic: Adds aromatic flavor to the filling.
• Salt and Pepper: Essential for seasoning the filling to perfection.
• Marinara Sauce: A rich tomato sauce that complements the creamy filling and keeps the pasta moist during baking.
• Olive Oil: Used for sautéing and greasing the baking dish.
• Fresh Parsley or Basil: Optional garnish that adds a burst of color and freshness.

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Add the jumbo shells and cook until al dente, about 9–10 minutes. Drain and lay them out on a clean tray or parchment paper to prevent sticking.

---

Step 2: Prepare the Spinach Filling

In a skillet, heat a little olive oil and sauté minced garlic until fragrant. Add the thawed and squeezed spinach and cook for 2–3 minutes to eliminate any remaining moisture. Set aside to cool slightly.

---

Step 3: Mix the Cheese Blend

In a large bowl, combine ricotta, half of the shredded mozzarella, half of the Parmesan, the cooked spinach mixture, a beaten egg, salt, and pepper. Stir until everything is evenly mixed.

---

Step 4: Preheat Oven and Prepare Baking Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or nonstick spray. Spread a generous layer of marinara sauce on the bottom of the dish.

---

Step 5: Stuff the Shells

Using a spoon or piping bag, fill each cooked pasta shell with the spinach and cheese mixture. Place the stuffed shells in a single layer on top of the marinara sauce in the dish.

---

Step 6: Add Sauce and Cheese on Top

Once all the shells are in the baking dish, spoon additional marinara sauce over them. Sprinkle with the remaining mozzarella and Parmesan cheese for a cheesy, golden topping.

---

Step 7: Bake the Shells

Cover the baking dish with foil and bake for 25 minutes. Remove foil and bake uncovered for an additional 10–15 minutes, or until the cheese is bubbly and lightly golden.

---

Step 8: Garnish and Serve

Remove from the oven and let cool slightly. Garnish with freshly chopped parsley or basil before serving for a touch of color and freshness.

How Long to Prepare the Spinach and Cheese Stuffed Shells

Preparation Time: You’ll need about 25–30 minutes to prep this dish. That includes boiling the shells, sautéing the spinach, and mixing the cheese filling. If you’re using pre-shredded cheese and frozen spinach, this can go even faster.

Cooking Time: Once the shells are assembled, they’ll need to bake for about 35–40 minutes total (25 minutes covered, 10–15 uncovered). Don’t forget to let them rest for a few minutes after baking so everything sets nicely.

Tips for Perfect Spinach and Cheese Stuffed Shells

• Drain the spinach thoroughly. Too much moisture can make the filling runny. Use a clean kitchen towel or cheesecloth to wring out all the water.
• Don’t overcook the pasta. Slightly undercooked shells are easier to stuff and won’t fall apart when baked.
• Use high-quality ricotta. A creamy, full-fat ricotta makes all the difference in flavor and texture.
• Taste the filling. Before adding the egg, give it a quick taste to ensure it’s seasoned well.
• Add a layer of sauce on top. This keeps the shells moist and helps the cheese brown nicely.

---

Watch Out for These Mistakes While Cooking

• Skipping the squeeze on spinach. Any leftover water in the spinach will dilute your filling and make it watery.
• Using cold filling. Let the sautéed spinach cool before mixing with cheese to avoid melting or scrambling the egg.
• Crowding the baking dish. Give each shell a little space so they cook evenly and are easier to serve.
• Not enough sauce. Be generous with the marinara; dry shells aren’t nearly as satisfying.
• Overbaking. If you bake too long uncovered, the cheese can get tough instead of melty.
