Preparation Phase & Tools to Use
Before diving into this decadent spinach-stuffed shells recipe, take a moment to prepare your cooking environment. Start by gathering all necessary tools and ingredients to streamline the cooking process. You’ll need a large pot for boiling the pasta, a skillet for sautéing the spinach, mixing bowls for combining the fillings, and a baking dish to create the final masterpiece.
Preheat your oven to 375°F (190°C), making sure it reaches the ideal temperature before placing the dish inside. Use a high-quality non-stick or ceramic baking dish (a 9×13 inch works perfectly) for easy clean-up and to ensure that nothing sticks. Having all your ingredients ready—measured and prepped—will make the cooking process smoother and more enjoyable. When cooking pasta shells, remember to use salted water, as it enhances the flavor of the pasta. A wooden spoon or silicone spatula will come in handy for mixing the filling, and a sharp knife or kitchen scissors will work well for chopping the spinach.

Ingredients
- 12 ounces Jumbo Pasta Shells
- 10 ounces Fresh Spinach
- 1 ½ cups Ricotta Cheese
- 8 ounces Cream Cheese
- 1 ½ cups Mozzarella Cheese, shredded
- ½ cup Parmesan Cheese, grated
- 2 cloves Garlic, minced
- 1 large Egg
- 3 cups Marinara Sauce
- 1 teaspoon Salt
- ½ teaspoon Black Pepper
Instructions
Step 1: Preheat Your Equipment
Begin by preheating your oven to 375°F (190°C). While the oven is heating, fill a large pot with water, add a generous amount of salt, and set it on the stovetop to boil. This will be used for cooking the jumbo pasta shells to al dente perfection, ensuring they hold their shape while being stuffed.
Step 2: Prepare the Spinach Filling
In a large skillet, heat a drizzle of olive oil over medium heat. Add the fresh spinach and sauté it until wilted, which should take about 3-4 minutes. Once cooked, remove any excess moisture by pressing the spinach between paper towels or using a colander, then chop it finely and set it aside. In a large mixing bowl, combine the ricotta cheese, cream cheese, shredded mozzarella, grated Parmesan, minced garlic, egg, salt, and black pepper. Stir well until everything is mixed together, then fold in the chopped spinach for a well-blended filling.
Step 3: Cook the Pasta Shells
Return to your boiling water and gently add the jumbo pasta shells. Cook according to package instructions until they are al dente. This usually takes around 9 to 11 minutes, depending on the brand. Once cooked, drain the shells carefully and place them on parchment paper or a clean kitchen towel to cool slightly. This step prevents them from sticking together and makes them easier to handle when filling.
Step 4: Assemble the Dish
In a 9×13 inch baking dish, spread a thin layer (about 1 cup) of marinara sauce across the bottom to prevent sticking and add flavor. Now, take each pasta shell and generously stuff it with the creamy spinach filling using a spoon or your hands. Place the filled shells in the baking dish, side by side, until it’s fully loaded. Repeat this process until all shells are stuffed and arranged neatly.
Step 5: Bake to Perfection
Pour the remaining marinara sauce over the stuffed shells, ensuring they are generously covered. Then, sprinkle the top with shredded mozzarella cheese for that delicious cheesy crust. Cover the baking dish with aluminum foil to lock in moisture and prevent the cheese from browning too quickly. Bake in your preheated oven for about 25 minutes. After this, remove the foil and continue baking for an additional 10 minutes, allowing the cheese to melt and become bubbly and golden.
Step 6: Finishing Touches
Once your stuffed shells are out of the oven, allow them to rest for a few minutes. This helps set the filling and makes serving easier. Garnish with fresh basil or extra grated Parmesan on top if desired, adding a fresh touch to your indulgent dish.

Variations
- Protein: Add cooked ground turkey, beef, or Italian sausage to the filling for an extra protein boost.
- Vegetables: Mix in sautéed mushrooms, bell peppers, or zucchini for added texture and flavor.
- Spices: Experiment with herbs such as basil, oregano, or red pepper flakes to spice up the filling.
Cooking Notes
- Make sure to wilt the spinach properly to avoid excess moisture in the filling.
- Don’t overcook the pasta shells; they’ll continue cooking in the oven.
- You can prepare the filling and stuff the shells a day ahead; then, just bake when ready to serve.
- Consider using low-fat versions of cheese for a lighter option without compromising flavor.
Serving Suggestions
- Pair the stuffed shells with a simple side salad drizzled with balsamic vinaigrette for a fresh contrast.
- Serve with garlic bread for a classic touch that complements the rich flavors.
Tips
- For the best flavor, use fresh herbs and quality cheeses.
- Experiment with different types of marinara sauce, like fire-roasted or spicy varieties, to change up the flavor profile.
- Leftovers can be stored in the refrigerator for up to 3 days, making great meal prep options.
- Reheat the stuffed shells gently in the oven or microwave, adding a splash of marinara sauce to keep them moist.
