1. Spinach and Ricotta Stuffed Shells (Yield: 4 Servings)

Ingredients

• 16 jumbo pasta shells
• 1 large egg
• 1 tsp kosher salt
• 1–1/2 tbsp olive oil
• 2 tsp fresh garlic, minced
• 1–1/4 cups marinara sauce
• 12 oz skim-milk ricotta cheese
• 1 tbsp fresh basil, finely chopped
• 1/2 tsp freshly-ground black pepper
• 1 cup shredded skim-milk mozzarella cheese
• 1/2 cup grated Parmesan cheese, plus more for serving
• 4 cups (packed) fresh spinach leaves, roughly chopped

Instructions

Preheat the oven to 375°F (190°C). Lightly coat a 9×13-inch baking dish with a small amount of olive oil or cooking spray to prevent sticking.

Bring a large pot of water to a rolling boil. Add the kosher salt and cook the jumbo pasta shells according to the package instructions until they are al dente. The shells should be tender but still firm enough to hold their shape when filled. Drain the shells and rinse them briefly under cool water to stop the cooking process. Arrange them on a baking sheet or large plate to prevent them from sticking together.

While the shells are cooking, heat the olive oil in a large skillet over medium heat. Add the minced garlic and cook for about 30 seconds, stirring frequently until fragrant. Add the chopped spinach and cook for 2 to 3 minutes, stirring often, until the spinach is wilted and any excess moisture has evaporated. Remove the skillet from the heat and allow the spinach mixture to cool slightly.

In a large mixing bowl, combine the ricotta cheese, egg, fresh basil, black pepper, half of the mozzarella cheese, and half of the Parmesan cheese. Stir until the ingredients are evenly blended. Add the cooled spinach and garlic mixture and mix thoroughly to create a smooth and creamy filling.

Spread approximately three-quarters of a cup of marinara sauce evenly across the bottom of the prepared baking dish. This layer of sauce helps keep the shells moist during baking and prevents them from sticking to the pan.

Using a spoon or small cookie scoop, carefully fill each cooked pasta shell with the spinach and ricotta mixture. Be generous with the filling, but avoid overstuffing to prevent the shells from splitting. Arrange the filled shells in a single layer in the baking dish with the open side facing upward.

Once all the shells are filled and arranged, spoon the remaining marinara sauce over the tops of the shells. Make sure the sauce is distributed evenly to keep everything moist and flavorful.

Sprinkle the remaining mozzarella cheese and Parmesan cheese evenly over the top. The cheese will melt during baking and create a delicious golden crust.

Cover the baking dish loosely with aluminum foil and place it in the preheated oven. Bake for 25 minutes. Remove the foil and continue baking for an additional 10 to 15 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.

Remove the baking dish from the oven and allow it to rest for about 5 minutes before serving. This short resting period helps the filling set and makes the shells easier to serve.

Garnish with additional grated Parmesan cheese and fresh basil if desired. Serve warm and enjoy.

2. Tips for Perfect Spinach and Ricotta Stuffed Shells

Cook the pasta shells just until al dente. Overcooked shells can tear easily during filling and baking.

Allow the spinach mixture to cool before combining it with the cheeses and egg. This helps maintain the proper texture of the filling.

Drain excess moisture from the cooked spinach if necessary. Too much liquid can make the filling watery and affect the final texture.

Use freshly grated Parmesan cheese for the best flavor and smoother melting.

Spread a layer of marinara sauce on the bottom of the baking dish before adding the shells. This prevents sticking and keeps the pasta tender.

Fill the shells evenly so they bake consistently and provide the same amount of filling in each serving.

Cover the dish during the first part of baking to retain moisture, then uncover it near the end for a beautifully melted and lightly browned cheese topping.

Let the stuffed shells rest for several minutes after baking. This allows the filling to firm up and makes serving easier.

3. Frequently Asked Questions

Can I prepare stuffed shells ahead of time?

Yes. You can assemble the entire dish up to one day in advance, cover it tightly, and refrigerate it. When ready to bake, add a few extra minutes to the baking time if the dish is cold from the refrigerator.

Can I freeze spinach and ricotta stuffed shells?

Absolutely. Assemble the shells in a freezer-safe dish, cover tightly, and freeze for up to three months. Thaw overnight in the refrigerator before baking for the best results.

Can I use frozen spinach instead of fresh spinach?

Yes. Frozen spinach works well as a substitute. Be sure to thaw it completely and squeeze out as much excess moisture as possible before adding it to the filling.

Can I make this recipe without egg?
