Step‑by‑Step Instructions for Spinach Ricotta Stuffed Shells with Tomato Sauce

Step 1: Prepare the Sauce
In a medium pot over medium heat, warm 2 tablespoons of olive oil. Add minced garlic and finely chopped shallots, sautéing until the onions turn translucent, about 3-4 minutes. Stir in 2 tablespoons of tomato paste and cook for another minute. Pour in 1 cup of white wine (or vegetable stock), allowing it to simmer until mostly evaporated, about 2 minutes. Then, add 28 ounces of tomato passata, 1 tablespoon of sugar, salt, and pepper. Keep it on low heat, uncovered, for 20 minutes until slightly thickened.

Step 2: Prepare the Filling
While the sauce simmers, squeeze excess water from 10 ounces of thawed spinach. In a large mixing bowl, blend 15 ounces of ricotta cheese, ½ cup of grated Parmesan, 1 cup of shredded cheese, 1 minced garlic clove, 1 egg, and a pinch of nutmeg, salt, and pepper. Mix until creamy and well-combined, creating a flavorful filling for your Spinach Ricotta Stuffed Shells.

Step 3: Assemble the Dish
Preheat your oven to 400°F (200°C). Start filling each jumbo pasta shell with about 2 tablespoons of the ricotta-spinach mixture, ensuring they are packed but not overflowing. In a 9 x 13 inch baking dish, pour a layer of the hot tomato sauce to cover the bottom. Arrange the filled shells atop the sauce, ensuring they are mostly submerged, which helps them cook beautifully.

Step 4: Bake
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 70 minutes until the shells are tender and the sauce is bubbling. After this, remove the foil, sprinkle the remaining shredded mozzarella and Parmesan over the top, and return to the oven uncovered for an additional 15 minutes, until the cheese is beautifully melted and golden.

Step 5: Garnish & Serve
Once baked, let your Spinach Ricotta Stuffed Shells cool for a few minutes. Before serving, garnish with fresh basil leaves and an optional sprinkle of extra Parmesan. This dish is not only visually appealing but also bursting with rich flavors, ready to be shared around your dinner table!

Make Ahead Options

These Spinach Ricotta Stuffed Shells with Tomato Sauce are fantastic for meal prep, allowing you to save time on busy weeknights! You can assemble the stuffed shells up to 24 hours in advance; simply cover them tightly with foil and refrigerate. This ensures that the flavors meld beautifully and the shells remain moist. When you’re ready to bake, just pop them in the preheated oven directly from the fridge, allowing for an extra 10-15 minutes of baking time. For longer storage, these shells can also be frozen before baking and stored for up to 3 months—just thaw overnight in the refrigerator before baking, and trust me, they’ll taste just as delicious!

Storage Tips for Spinach Ricotta Stuffed Shells with Tomato Sauce

Fridge: Store leftover Spinach Ricotta Stuffed Shells in an airtight container for up to 3 days. Make sure to cover them tightly to retain moisture.

Freezer: For longer storage, freeze the assembled but unbaked stuffed shells. Wrap them well in plastic wrap and then foil to maintain freshness for up to 2 months.

Reheating: To reheat, bake from frozen at 350°F (180°C) covered for about 40-50 minutes, or until heated through, removing the cover in the last 10-15 minutes to crisp the cheese.

Thawing: If you prep ahead and freeze, thawing the shells in the fridge overnight is safest before reheating. This helps preserve the texture and flavor when you enjoy this comforting dish again!

Spinach Ricotta Stuffed Shells with Tomato Sauce Recipe FAQs

What type of spinach should I use for the filling?
Absolutely! I recommend using thawed frozen spinach for convenience, but you can certainly use fresh spinach. If you choose fresh, sauté it lightly and squeeze out any excess water to prevent a watery filling.

How should I store leftovers of my Spinach Ricotta Stuffed Shells?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. Simply make sure they are tightly covered to keep that delightful moisture intact. They make for a perfect next-day lunch!

Can I freeze Spinach Ricotta Stuffed Shells?
Of course! To freeze, wrap the assembled but unbaked shells tightly in plastic wrap and then cover with foil. They will keep well for up to 2 months. Just remember, when you’re ready to enjoy them again, bake from frozen at 350°F (180°C) for about 40-50 minutes.

What if my sauce seems too watery?
Very common! If your sauce turns out watery, ensure it's cooked down properly before adding the stuffed shells. You can thicken it by simmering it longer or by adding a bit of tomato paste. This way, the shells won't become soggy during baking—a key for that perfect texture!

Are there any dietary considerations I should be aware of?
Definitely! If you’re cooking for someone with dairy allergies, you can swap out the cheeses for non-dairy alternatives. Additionally, make sure any store-bought tomato products are gluten-free if that’s a concern. The recipe is naturally vegetarian, making it a great option for many dietary preferences!
