Spinach and Ricotta Stuffed Shells

Why You’ll Love This Recipe

I love this recipe because it combines tender pasta, creamy ricotta, melted mozzarella, and flavorful Parmesan in every bite. The spinach adds freshness and color, making the filling both delicious and nutritious.

I also appreciate that this dish can be prepared ahead of time and baked when needed. The rich marinara sauce keeps the shells moist while creating a wonderful balance with the cheesy filling.

Another reason I enjoy this recipe is that it looks impressive when served, yet it uses simple ingredients that are easy to find.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

16 jumbo pasta shells (cook a couple of extra shells to allow for breakage)

1-1/2 tablespoons olive oil

2 teaspoons fresh garlic, minced

4 cups packed fresh spinach leaves, roughly chopped

12 ounces skim-milk ricotta cheese

1 cup shredded skim-milk mozzarella cheese

1/2 cup grated Parmesan cheese, plus more for serving

1 large egg

1 tablespoon fresh basil, finely chopped

1 teaspoon kosher salt

1/2 teaspoon freshly ground black pepper

1-1/4 cups marinara sauce

Directions

I preheat the oven to 375°F and cook the jumbo pasta shells according to the package directions until al dente. After draining them, I set them aside to cool slightly.

Meanwhile, I heat the olive oil in a large skillet over medium-high heat. Once the oil begins to shimmer, I add the minced garlic and cook it for about 1 to 2 minutes until fragrant and lightly browned.

I add the chopped spinach and cook, stirring occasionally, until the leaves wilt and reduce in volume by about half while still maintaining their bright green color. I remove the skillet from the heat and allow the spinach mixture to cool.

In a large mixing bowl, I combine the cooked spinach, ricotta cheese, mozzarella cheese, Parmesan cheese, egg, basil, salt, and pepper. I stir everything together until the filling is thoroughly mixed.

I spread 1/2 cup of marinara sauce across the bottom of an 8-inch by 8-inch baking dish.

I generously fill each pasta shell with the spinach and ricotta mixture and arrange them in the prepared baking dish.

I spoon the remaining marinara sauce over the stuffed shells.

I cover the dish with aluminum foil and bake for 25 minutes.

After that, I remove the foil and continue baking for 10 to 15 minutes, until the sauce is bubbling and the tops begin to brown.

I serve the shells warm with an extra sprinkle of Parmesan cheese.

Variations

I sometimes add sautéed mushrooms to the filling for extra flavor and texture.

For a richer version, I use whole-milk ricotta and mozzarella instead of skim-milk varieties.

I enjoy adding chopped sun-dried tomatoes or roasted red peppers to the filling for a Mediterranean-inspired twist.

When I want extra protein, I mix cooked Italian sausage or shredded chicken into the cheese mixture.

I occasionally substitute kale for spinach when I want a slightly heartier filling.

storage/reheating

I store leftover stuffed shells in an airtight container in the refrigerator for up to 4 days.

For longer storage, I freeze the baked shells in a freezer-safe container for up to 3 months. I thaw them overnight in the refrigerator before reheating.

To reheat, I place the shells in a baking dish, cover with foil, and warm them in a 350°F oven for about 15 to 20 minutes, or until heated through.

I can also reheat individual portions in the microwave for a quick meal.
