Ingredients

12 large pasta shells
2 tablespoons olive oil or unsalted butter
1 medium onion, finely diced
2 cloves garlic, minced
10 ounces fresh spinach, chopped
1 teaspoon kosher salt
½ teaspoon black pepper
1 teaspoon dried Italian herbs (or a mix of oregano, basil, and thyme)
15 ounces ricotta cheese
½ cup grated Parmesan cheese
1 cup shredded mozzarella cheese, divided
1 large egg, lightly beaten
2 cups marinara sauce, homemade or store-bought

Substitution Notes

For a dairy-free version, use plant-based ricotta and mozzarella.
For gluten-free, substitute pasta shells with gluten-free pasta.
You can use frozen spinach, thoroughly thawed and drained, instead of fresh spinach.
To lighten the dish, use part-skim ricotta or reduce the amount of mozzarella.

Step-by-Step Instructions

Step 1: Prepare the Spinach Filling

Heat olive oil in a skillet over medium heat. Add diced onion and sauté until translucent, about 3-4 minutes. Add garlic and cook until fragrant, approximately 30 seconds. Add chopped spinach, salt, pepper, and Italian herbs. Cook until the spinach wilts completely and any excess liquid evaporates. Remove from heat and let cool slightly.

Step 2: Combine the Cheeses

In a large mixing bowl, combine ricotta, ½ cup Parmesan, and half of the mozzarella. Add the beaten egg and stir until smooth. Fold the cooled spinach mixture into the cheese until evenly incorporated. Taste and adjust seasoning if necessary. This is your spinach ricotta stuffed shells filling.

Step 3: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Add the pasta shells and cook until al dente, about 8-10 minutes. Drain and rinse under cold water to prevent sticking. Set aside on a clean towel, open side up, ready for filling.

Step 4: Assemble the Stuffed Shells

Preheat your oven to 375°F (190°C). Spread 1 cup of marinara sauce on the bottom of a 9×13-inch baking dish. Carefully spoon the spinach ricotta mixture into each shell. Place the filled shells seam side up in the dish. Once all shells are filled, pour the remaining marinara sauce evenly over the top and sprinkle with the remaining mozzarella and Parmesan cheese.

Step 5: Bake to Perfection

Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, until the cheese is melted and slightly golden. Let the dish rest for 5 minutes before serving. This allows the filling to set and makes the shells easier to serve.

How to Serve

Stuffed shells with spinach are best served hot, fresh from the oven. Arrange the shells neatly on a large serving platter for family style meals, or serve individual portions on plates for a more formal presentation. Garnish with freshly chopped parsley or basil for a touch of color and added aroma. Drizzle a little extra olive oil or sprinkle more Parmesan if desired to enhance the flavor and presentation.

Pair the dish with a simple green salad, garlic bread, or roasted vegetables. These sides balance the richness of the ricotta and cheese, while complementing the Italian flavors. A glass of red wine or sparkling water elevates the meal, turning this comforting casserole into a memorable Italian dinner experience.

Additional Tips

Always drain spinach thoroughly to prevent watery filling.
Use room-temperature ricotta for smoother mixing.
Do not overfill shells to avoid spillage during baking.
Cover with foil initially to ensure even cooking and moisture retention, then uncover to allow the cheese to brown.
