Ingredients

For the Shells:

• 20–22 jumbo pasta shells (about 8 oz / 225g)

For the Filling:

• 2 cups (450g) ricotta cheese
• 1 cup (100g) shredded mozzarella cheese
• 1/2 cup (50g) grated Parmesan cheese
• 2 cups (60g) fresh spinach (or 1 cup frozen spinach, thawed and drained)
• 1 large egg
• 2 cloves garlic, minced
• 1 teaspoon Italian seasoning
• 1/4 teaspoon nutmeg (optional but adds depth)
• Salt and pepper, to taste

For the Sauce:

• 2 cups (480ml) marinara sauce (homemade or store-bought)
• 1/2 teaspoon dried basil
• 1/2 teaspoon oregano

For Topping:

• 1/2 cup (50g) mozzarella cheese
• 1/4 cup (25g) grated Parmesan cheese
• Fresh basil or parsley, chopped (for garnish)

Cooking Directions

1. Preheat oven to 375°F (190°C).
2. Cook pasta shells in salted boiling water until just al dente (about 1–2 minutes less than package instructions). Drain and lay them on a tray to cool slightly.
3. Prepare the filling: In a large bowl, mix ricotta, mozzarella, Parmesan, spinach, egg, garlic, Italian seasoning, nutmeg, salt, and pepper until smooth.
4. Prepare the sauce: Spread 1 cup of marinara sauce evenly over the bottom of a 9×13-inch baking dish.
5. Stuff the shells: Spoon the ricotta-spinach filling into each shell (about 2 tablespoons per shell) and arrange them in the baking dish.
6. Top with sauce and cheese: Spoon remaining marinara sauce over the stuffed shells. Sprinkle with mozzarella and Parmesan.
7. Bake: Cover with foil and bake for 20 minutes. Remove foil and bake another 10–15 minutes, until bubbly and golden on top.
8. Cool slightly before serving. Garnish with fresh basil or parsley.

Step-by-Step Preparation Method

1. Boil the shells: Bring a large pot of salted water to a boil and cook the pasta shells until just tender. Drain and set aside to cool.
2. Make the filling:
   • If using fresh spinach, sauté it in a little olive oil until wilted, then squeeze out excess moisture.
   • Combine spinach, ricotta, mozzarella, Parmesan, egg, garlic, and seasoning in a bowl. Mix until creamy and thick.
3. Prepare the baking dish: Spread a thin layer of marinara sauce on the bottom to prevent sticking.
4. Stuff each shell: Use a small spoon or piping bag to fill each shell generously with the ricotta mixture.
5. Arrange and top: Place shells snugly in the dish, spoon over remaining sauce, and sprinkle cheese on top.
6. Bake covered: 20 minutes to heat through.
7. Uncover and bake: 10–15 more minutes for a bubbly, lightly browned top.
8. Serve hot: Let it rest for 5 minutes before plating.

How to Serve

Serve hot from the oven, sprinkled with fresh herbs and extra Parmesan. Pair with:

• A crisp Caesar salad or mixed greens
• Garlic bread or toasted baguette slices
• A glass of Chianti or Pinot Grigio for an elegant dinner

These stuffed shells also make a fantastic centerpiece for a family-style Italian feast.

Recipe Tips

• Undercook the pasta shells slightly, as they’ll finish cooking in the oven.
• Drain spinach thoroughly to prevent watery filling.
• Use whole-milk ricotta for a creamier, richer texture.
• Add red pepper flakes for a subtle kick.
• Make ahead: Assemble up to a day in advance and refrigerate until ready to bake.

Variations

• Three-Cheese Stuffed Shells: Add ricotta, mozzarella, and fontina for an extra cheesy filling.
• Meat Lovers: Mix cooked ground beef, Italian sausage, or turkey into the filling.
• Vegan Version: Use vegan ricotta (almond-based or tofu), dairy-free mozzarella, and skip the egg (use a flax egg if needed).
• Spinach and Mushroom Shells: Add sautéed mushrooms for an earthy flavor boost.
• Pesto Spinach Shells: Mix a few tablespoons of basil pesto into the filling for extra herby depth.

Freezing and Storage

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer (unbaked): Assemble the dish completely, cover tightly with foil, and freeze for up to 3 months.
  • To bake from frozen: Bake covered for 45–50 minutes, then uncover and bake for 15 minutes.
• Freezer (baked): Cool completely before freezing. Reheat in a 350°F (175°C) oven for 25–30 minutes.

Special Equipment Needed

• 9×13-inch baking dish
• Large pot for boiling pasta
• Colander
• Mixing bowls
• Spoon or piping bag for filling shells
