Instructions

• Cook the pasta shells to al dente then put them out on a single layer on a kitchen towel so they won’t stick together
• In a skillet over medium heat combine the oil and onion. Cook until onions are soft and translucent than add the garlic and cook until fragrant (1-2 more minutes).
• In a separate bowl combine ricotta, cream cheese, egg, parsley, salt, basil, parmesan, spinach, and half of the mozzarella cheese. Mix well.
• Preheat oven to 350° F. Get two 9×13 inch baking dishes and pour out half a jar of the marinara sauce into each pan.
• Take the cheese filling and put it into a gallon size ziplock bag. Snip one corner and pipe the filling into the shells, about 2-3 Tablespoons worth in each shell.
• Fill all the shells (about 20 per pan) then cover with remaining marinara and mozzarella.
• Bake covered at 350°F for 40 minutes then uncovered for an additional 5-10 minutes.

Diving Deeper into the Ingredients for Perfect Stuffed Shells

The success of these Spinach and Basil Stuffed Shells hinges on a few key ingredients, each playing a vital role in creating that rich, comforting Italian flavor profile. Let’s take a closer look at what makes this dish so special:

• Jumbo Pasta Shells: These large, concave pasta shapes are specifically designed to cradle generous amounts of filling. Cooking them al dente is crucial; they should be firm to the bite, as they will continue to cook in the oven. Overcooked shells can tear easily during stuffing. Laying them out on a kitchen towel after draining helps prevent them from sticking together, making the stuffing process much smoother.
• The Four Cheese Blend:
  • Ricotta Cheese: The traditional base for stuffed pasta fillings, ricotta provides a light, fluffy texture and a subtle milky sweetness. Using a good quality, full-fat ricotta will yield the creamiest results.
  • Cream Cheese (Softened): This is our secret ingredient! Cream cheese adds an incredible richness and a slight tang that beautifully complements the other cheeses. Softening it to room temperature is essential for a lump-free, smooth filling.
  • Shredded Parmesan Cheese: Known for its sharp, salty, and nutty flavor, Parmesan is indispensable. It adds a crucial layer of umami that elevates the entire dish. Freshly grated Parmesan will always offer superior flavor to pre-shredded varieties.
  • Grated Mozzarella Cheese: Mozzarella provides the iconic melt and stretch that makes baked pasta dishes so appealing. We use it both in the filling for moisture and flavor, and generously on top for that golden, bubbly crust.
• Fresh Spinach and Basil: These herbs are more than just a garnish; they infuse the dish with vibrant, fresh flavors. Fresh spinach wilts down significantly, so don’t be afraid to use a good amount. Fresh basil, with its sweet and peppery notes, is absolutely transformative. If fresh basil isn’t available, dried basil can be substituted, but reduce the quantity as its flavor is more concentrated.
• Marinara Sauce: A good quality marinara sauce forms the flavorful bed and topping for your shells. While homemade is always wonderful, a premium store-bought sauce, like the Kirkland Signature mentioned, can save significant time without compromising on taste. Choose one with good, simple ingredients for the best results.
• Aromatics (Onion and Garlic): Sautéing diced onion until soft and translucent, then adding minced garlic until fragrant, builds a foundational layer of savory flavor that permeates the entire dish. Don’t skip this step!

Detailed Step-by-Step Guide and Pro Tips

Crafting these stuffed shells is a rewarding process, and with these detailed steps and tips, you’ll achieve perfection every time:

1. Prepare the Pasta Shells

Begin by cooking your jumbo pasta shells in generously salted boiling water according to package directions, but aim for al dente. This means they should still have a slight bite to them. As soon as they are cooked, drain them and immediately lay them out in a single layer on a clean kitchen towel or parchment paper. This crucial step prevents them from sticking together and allows them to cool slightly, making them much easier to handle and stuff without tearing.

2. Sauté the Aromatics

In a skillet, heat 2 tablespoons of oil over medium heat. Add the diced onion and cook, stirring occasionally, until it becomes soft and translucent. This usually takes about 5-7 minutes. Once the onions are ready, add the minced garlic and cook for another 1-2 minutes until fragrant. Be careful not to burn the garlic, as it can turn bitter. This aromatic base will add depth to your cheese filling.

3. Create the Luxurious Cheese Filling

In a large mixing bowl, combine the ricotta cheese, softened cream cheese, beaten egg, dried parsley flakes, salt, chopped fresh basil (or dried basil), shredded Parmesan cheese, chopped fresh spinach, and half of the grated mozzarella cheese. Mix thoroughly until all ingredients are well combined and the filling is smooth and uniform. A sturdy spoon or your hands (with clean gloves!) work best for this. Ensure the cream cheese is fully incorporated for that extra creamy texture.

4. Prepare Your Baking Dishes

Preheat your oven to 350°F (175°C). Grab two 9×13 inch baking dishes. Pour approximately half a jar (16 oz) of your preferred marinara sauce into the bottom of each pan, spreading it evenly. This creates a flavorful bed for the shells and prevents them from sticking.

5. Efficiently Stuff the Shells

Transfer the creamy cheese filling into a gallon-sized ziplock bag. Snip one corner of the bag to create a piping bag. This method is incredibly efficient for filling the shells neatly and quickly. Hold each shell open and pipe about 2-3 tablespoons of filling into it. Aim for about 20 filled shells per baking pan, arranging them snugly in a single layer over the marinara sauce. This makes for easy serving and even baking.

6. Layer and Bake to Perfection

Once all the shells are filled and arranged, pour the remaining marinara sauce evenly over the top of the shells in both pans. Then, generously sprinkle the reserved half of the mozzarella cheese over each dish. Cover both baking dishes tightly with aluminum foil. Bake the covered dishes in the preheated oven for 40 minutes. After 40 minutes, remove the foil and bake for an additional 5-10 minutes, or until the cheese is melted, bubbly, and lightly golden brown. This uncovered step is key to achieving that irresistible cheesy crust.

Make-Ahead & Freezer-Friendly Instructions

One of the best features of this recipe is its adaptability for make-ahead meals and freezing. Here’s how to best utilize its two-for-one potential:

• For Immediate Baking: Follow all instructions up to step 6. Bake one pan as directed and enjoy!
• For Freezing (Unbaked): Prepare the second pan of stuffed shells completely, including the marinara sauce and mozzarella topping, but do NOT bake it. Cover the pan tightly with two layers of aluminum foil and label clearly with the date and baking instructions. Freeze for up to 3 months.
• Baking from Frozen: When you’re ready to bake, remove the frozen dish from the freezer. You can bake it directly from frozen, though it will require more baking time. Preheat oven to 350°F (175°C). Keep the pan covered with foil and bake for 60-70 minutes, or until heated through. Then, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and lightly browned. For best results, allow the frozen dish to thaw in the refrigerator overnight before baking, then follow the original baking instructions.
• Freezing Leftovers (Baked): If you have leftover baked shells, allow them to cool completely. Transfer individual portions to airtight containers or wrap tightly in foil and plastic wrap. Reheat in the microwave or oven until warm.

Serving Suggestions and Customization Ideas

These Spinach and Basil Stuffed Shells are a complete meal on their own, but they pair wonderfully with a few complementary sides:

• Garlic Bread or Crusty Ciabatta: Perfect for soaking up the delicious marinara sauce.
• Simple Green Salad: A fresh salad with a light vinaigrette provides a refreshing contrast to the rich pasta.
• Roasted Vegetables: Asparagus, broccoli, or zucchini roasted with a little olive oil and garlic would be a great addition.

Feel free to get creative and customize this recipe to your family’s taste:

• Add Protein: Brown 1 lb of ground beef, Italian sausage, or ground turkey with the onions and garlic, then drain any excess fat before adding it to the cheese filling.
• Extra Veggies: Sauté finely diced bell peppers, mushrooms, or zucchini and add them to the filling for extra nutrients and flavor.
• Spice It Up: A pinch of red pepper flakes added to the marinara sauce or the cheese filling will give it a nice kick.
• Different Cheese Combinations: Experiment with other Italian cheeses like provolone or fontina for subtle flavor variations.
• Homemade Marinara: If you have time, using your favorite homemade marinara sauce will truly take this dish to the next level.

Troubleshooting Common Questions

• Why are my shells sticking together? This usually happens if they are overcooked or not spread out to cool properly after draining. Ensure they are cooked al dente and given space to cool.
• My filling is watery. What went wrong? Excess moisture from ricotta or spinach can lead to a watery filling. Make sure to drain your ricotta if it seems excessively wet. For spinach, squeeze out any excess water after chopping if you notice it’s very moist.
• Can I make this vegetarian? Absolutely! The recipe as written is vegetarian.
• Can I use frozen spinach? Yes, but ensure you thaw it completely and squeeze out as much water as possible before adding it to the filling.
