Ingredients
For the Stuffed Shells:
-
- Jumbo Pasta Shells (24-30 shells): Jumbo pasta shells are the star of the show, providing the perfect vessels for our flavorful spinach and ricotta filling. Look for good quality jumbo shells; brands like Barilla or De Cecco are readily available and work well. Make sure to purchase a little extra, as some shells might break during cooking.
-
- Fresh Spinach (1 pound): Fresh spinach forms the leafy green base of our filling, adding nutrients and a subtle earthy flavor. You can use baby spinach or mature spinach. Baby spinach is more tender and requires less cooking time, while mature spinach might need a bit longer to wilt down. Frozen spinach can be used as a substitute (see FAQ section for details), but fresh spinach provides a brighter flavor and better texture.
-
- Ricotta Cheese (15 ounces, whole milk or part-skim): Ricotta cheese is the creamy, cheesy heart of the filling. Whole milk ricotta will provide a richer, creamier texture, while part-skim ricotta is a lighter option. Look for good quality ricotta cheese; brands like Calabro or BelGioioso are known for their smooth texture and fresh flavor. Avoid ricotta that seems overly watery.
-
- Parmesan Cheese, grated (½ cup, plus extra for topping): Parmesan cheese adds a salty, savory, and umami depth to the filling and enhances the overall cheesy flavor. Use freshly grated Parmesan cheese for the best flavor and melting quality. High-quality Parmigiano-Reggiano is ideal, but Grana Padano is a good and more budget-friendly alternative. You’ll also need extra for topping the shells before baking.
-
- Egg (1 large): An egg acts as a binder in the filling, helping to hold it together and prevent it from being too loose. Use a large egg and whisk it lightly before adding it to the ricotta mixture.
-
- Garlic, minced (2 cloves): Garlic adds a pungent, savory flavor that complements the spinach and ricotta beautifully. Freshly minced garlic is always preferred for its robust aroma and flavor.
-
- Dried Oregano (1 teaspoon): Dried oregano adds a classic Italian herb flavor to the filling, enhancing the overall savory profile. Use good quality dried oregano for the best aroma. Fresh oregano, finely chopped (about 1 tablespoon), can also be used if you have it on hand.
-
- Dried Basil (1 teaspoon): Dried basil adds another layer of Italian herb flavor, complementing the oregano and spinach. Like oregano, use good quality dried basil or fresh basil, finely chopped (about 1 tablespoon).
-
- Salt and Black Pepper: Seasoning is crucial to bring out the flavors of the filling. Use kosher salt or sea salt and freshly ground black pepper to taste. Remember to season in layers throughout the cooking process, tasting and adjusting as needed.
-
- Nutmeg, grated (pinch): A pinch of freshly grated nutmeg (or ground nutmeg) adds a subtle warm, nutty note that enhances the richness of the ricotta and spinach. A little nutmeg goes a long way, so just a pinch is enough.
For the Marinara Sauce:
-
- Olive Oil (2 tablespoons): Olive oil is used as the base for sautéing the aromatics in the marinara sauce. Use good quality extra virgin olive oil for its flavor and health benefits.
-
- Yellow Onion, diced (1 medium): Onion forms the aromatic base of the marinara sauce, providing a mild, sweet flavor when sautéed. Yellow onion is a good all-purpose choice.
-
- Garlic, minced (3 cloves): Garlic is essential for a flavorful marinara sauce, adding a pungent, savory depth. Use freshly minced garlic for the best flavor.
-
- Canned Crushed Tomatoes (28 ounces): Canned crushed tomatoes are the main ingredient of the marinara sauce, providing the tomato base and rich flavor. Use good quality crushed tomatoes; San Marzano tomatoes are often considered the best for their sweetness and low acidity.
-
- Tomato Paste (2 tablespoons): Tomato paste adds concentrated tomato flavor and richness to the marinara sauce, deepening its color and intensity.
-
- Dried Oregano (1 teaspoon): Dried oregano adds a classic Italian herb flavor to the marinara sauce.
-
- Dried Basil (1 teaspoon): Dried basil complements the oregano and crushed tomatoes, enhancing the Italian flavor profile of the sauce.
-
- Sugar (1 teaspoon): A pinch of sugar balances the acidity of the tomatoes and enhances their natural sweetness.
-
- Salt and Black Pepper: Seasoning is crucial for a flavorful marinara sauce. Use kosher salt or sea salt and freshly ground black pepper to taste.
-
- Fresh Basil Leaves (for garnish, optional): Fresh basil leaves add a vibrant green color and fresh, herbaceous aroma as a garnish for the finished dish.
Instructions
Step 1: Prepare the Marinara Sauce
-
- Sauté Aromatics: In a large saucepan or Dutch oven, heat the olive oil over medium heat. Add the diced onion and sauté until softened and translucent, about 5-7 minutes. Don’t let the onion brown.
-
- Add Garlic: Add the minced garlic to the pot and cook for another minute until fragrant, being careful not to burn it.
-
- Add Tomato Paste: Stir in the tomato paste and cook for 1-2 minutes, stirring constantly. Cooking the tomato paste deepens its flavor.
-
- Add Crushed Tomatoes and Seasonings: Pour in the canned crushed tomatoes. Add the dried oregano, dried basil, sugar, salt, and black pepper. Stir well to combine.
-
- Simmer Sauce: Bring the sauce to a simmer, then reduce the heat to low, cover, and simmer for at least 30 minutes, or up to 1 hour, stirring occasionally. Simmering allows the flavors to meld and deepen. The longer it simmers, the richer the flavor will become. While the sauce simmers, you can prepare the stuffed shells.
Step 2: Cook the Jumbo Pasta Shells
-
- Cook Shells Al Dente: While the marinara sauce is simmering, cook the jumbo pasta shells according to package directions for al dente. Al dente means “to the tooth” in Italian – the pasta should be cooked through but still slightly firm to the bite. This prevents the shells from becoming mushy when baked.
-
- Drain and Rinse: Once cooked, drain the pasta shells thoroughly in a colander. Rinse them with cold water to stop the cooking process and prevent them from sticking together.
-
- Set Aside: Gently set the cooked shells aside to cool slightly while you prepare the filling.
Step 3: Prepare the Spinach and Ricotta Filling
-
- Cook Spinach: If using fresh spinach, you need to wilt it first. There are a couple of ways to do this:
-
- Microwave Method: Place the spinach in a microwave-safe bowl with a tablespoon of water. Microwave on high for 2-3 minutes, or until wilted.
-
- Stovetop Method: Heat a large skillet over medium heat. Add the spinach and cook, stirring occasionally, until it wilts down, about 3-5 minutes. You may need to do this in batches if you have a large amount of spinach.
-
- Cook Spinach: If using fresh spinach, you need to wilt it first. There are a couple of ways to do this:
-
- Drain Spinach Thoroughly: Once wilted, it’s crucial to remove as much excess moisture from the spinach as possible. Place the spinach in a fine-mesh sieve or colander and press out the excess water with the back of a spoon or your hands. You can also squeeze it in a clean kitchen towel or cheesecloth. This step prevents the filling from becoming watery.
-
- Chop Spinach: Roughly chop the drained spinach.
-
- Combine Filling Ingredients: In a medium bowl, combine the ricotta cheese, grated Parmesan cheese, egg, minced garlic, dried oregano, dried basil, nutmeg, salt, and black pepper. Mix well to combine all ingredients evenly.
-
- Add Spinach to Filling: Add the chopped, drained spinach to the ricotta mixture and stir until well combined.
Step 4: Stuff the Pasta Shells
-
- Preheat Oven: Preheat your oven to 375°F (190°C).
-
- Assemble Dish: Spread a thin layer of the marinara sauce (about 1 cup) in the bottom of a 9×13 inch baking dish. This layer prevents the shells from sticking and keeps them moist during baking.
-
- Stuff Shells: Take each cooked jumbo pasta shell and spoon or pipe (using a piping bag or zip-top bag with a corner cut off for easier stuffing) the spinach and ricotta filling into each shell. Be generous with the filling, but avoid overstuffing so they don’t burst.
-
- Arrange Shells in Baking Dish: Arrange the stuffed shells in the baking dish in a single layer, open-side up, on top of the marinara sauce base. Pack them snugly but not too tightly.
-
- Pour Marinara Sauce Over Shells: Pour the remaining marinara sauce evenly over the stuffed shells, making sure to cover them well. You want the shells to be mostly submerged in the sauce, but the tops can be slightly exposed.
-
- Sprinkle with Parmesan Cheese: Sprinkle the top of the stuffed shells evenly with the remaining grated Parmesan cheese. This will create a golden, cheesy crust as it bakes.
Step 5: Bake the Stuffed Shells
-
- Cover and Bake: Cover the baking dish tightly with aluminum foil. This helps to steam the shells and keep them moist while they bake.
-
- Bake: Bake in the preheated oven for 25 minutes, covered.
-
- Uncover and Bake Further: Remove the foil and continue to bake for another 15-20 minutes, or until the cheese is melted, golden brown, and bubbly, and the marinara sauce is heated through and bubbling. The pasta shells should be tender, and the filling should be hot and cooked through.
-
- Broil for Extra Browning (Optional): For extra browning on top, you can broil for the last 1-2 minutes, watching carefully to prevent burning.
Step 6: Garnish and Serve
-
- Rest Before Serving: Let the baked Spinach and Ricotta Stuffed Shells rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and the flavors to settle.
-
- Garnish: Garnish with fresh basil leaves, if desired, for a pop of color and fresh aroma.
-
- Serve Hot: Serve the Spinach and Ricotta Stuffed Shells hot, directly from the baking dish or portioned onto plates.
