Step‑by‑Step Instructions for Stuffed Shells with Spinach
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (177°C). This step is crucial, as it ensures your Stuffed Shells with Spinach will bake evenly and thoroughly. While the oven heats up, you can prep the filling, making sure everything is ready to go as soon as the shells are stuffed.
Step 2: Sauté Spinach
In a large skillet, heat a tablespoon of vegetable oil over medium heat. Add the fresh baby spinach and sauté for about 3-4 minutes until it wilts down to a tender consistency. The spinach will shrink significantly, so keep an eye on it for vibrant green color. Once done, remove the skillet from the heat and allow the spinach to cool slightly.
Step 3: Combine Filling
In a mixing bowl, combine the well-drained ricotta cheese, roasted red peppers, sautéed spinach, Parmesan cheese, lightly beaten eggs, and fine sea salt. Stir until the mixture is blended and creamy, ensuring there are no lumps. This flavorful filling for your Stuffed Shells with Spinach should be rich and well-seasoned, ready to envelop the shells.
Step 4: Stuff Shells
Carefully take your cooked jumbo pasta shells and begin to stuff each one with the spinach and ricotta mixture. Use a spoon or your hands to pack the filling generously into each shell. Arrange the stuffed shells snugly in a greased baking dish, with the open side facing up, to prepare for the marinara sauce.
Step 5: Add Sauce and Cheese
Pour the marinara sauce over the stuffed shells, making sure they are well coated. Use a spoon to gently spread the sauce evenly, ensuring every shell stands out. Next, sprinkle the shredded mozzarella cheese generously on top, allowing it to create a bubbly, golden crust while baking.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 15-20 minutes. You’ll know your Stuffed Shells with Spinach are ready when the cheese is melted and slightly golden, and the sauce is bubbling along the edges. Be sure to watch closely during the final minutes to achieve that perfect finish.
Step 7: Garnish
Once baked, remove the dish from the oven and let it cool for about 5 minutes. For a lovely presentation, garnish with minced parsley and additional Parmesan cheese if desired. This final touch adds freshness and flavor, making your meal even more inviting and delicious!

How to Store and Freeze Stuffed Shells with Spinach
Fridge: Store leftover stuffed shells in an airtight container for up to 3 days, ensuring they are covered with marinara sauce to maintain moisture.
Freezer: For longer storage, freeze unbaked or baked stuffed shells for up to 2-3 months. Wrap them tightly in plastic wrap and aluminum foil to prevent freezer burn.
