Whether you’re hosting a cozy family dinner, planning a make-ahead meal for the week, or simply craving a classic baked pasta dish, this recipe is for you.
In this 6-step guide to cooking Spinach and Ricotta Stuffed Shells, we’ll walk you through every stage — from preparing the filling to baking the dish to perfection — so you can enjoy restaurant-quality flavor right from your own kitchen.
Step 1: Gather Your Ingredients

Before you start, organize all your ingredients. Stuffed shells are easy to make, but having everything prepped ensures a smooth cooking process.
For the Filling:
- 1 box (12 oz) jumbo pasta shells
- 2 cups ricotta cheese (whole milk for creaminess)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 cups fresh spinach (or 10 oz frozen spinach, thawed and squeezed dry)
- 1 egg (to bind the mixture)
- 2 garlic cloves, minced
- 1 teaspoon dried Italian seasoning (or a mix of oregano, basil, and thyme)
- Salt and pepper to taste
- A pinch of nutmeg (optional but enhances the ricotta flavor)
For the Sauce and Topping:
- 3 cups marinara sauce (store-bought or homemade)
- ½ cup shredded mozzarella cheese (for topping)
- ¼ cup grated Parmesan cheese
- 1 tablespoon olive oil
Tip: Use high-quality ricotta and marinara sauce — they make all the difference in achieving that authentic Italian flavor.
Step 2: Cook the Pasta Shells

The jumbo pasta shells form the base of your dish, so it’s important to cook them perfectly — soft enough to stuff, but firm enough to hold their shape during baking.
- Bring a large pot of salted water to a rolling boil.
- Add the pasta shells and cook for about 9–10 minutes, just until al dente (slightly firm to the bite).
- Drain the shells and rinse them under cold water to stop the cooking process.
- Drizzle lightly with olive oil to prevent them from sticking together.
Lay the cooked shells on a tray or plate so they’re ready to fill later.
Pro Tip: Cook a few extra shells in case some tear during stuffing — it happens to the best of us!
Step 3: Prepare the Spinach and Ricotta Filling

Now for the heart of the dish — that creamy, flavorful spinach and ricotta filling that makes these shells irresistible.
- In a skillet, heat 1 tablespoon olive oil over medium heat. Add the minced garlic and sauté until fragrant (about 30 seconds).
- Add chopped spinach and cook until wilted (for fresh spinach) or heated through (for frozen spinach). Remove from heat and let cool slightly.
- In a large mixing bowl, combine ricotta, mozzarella, Parmesan, egg, cooked spinach, Italian seasoning, salt, pepper, and nutmeg.
- Mix until well combined and creamy. The mixture should hold together but still be soft enough to spoon easily.
Taste the filling — it should be flavorful and slightly salty. Remember, it will mellow out once baked in sauce.
Optional Add-ins: Chopped basil, sun-dried tomatoes, or a little lemon zest for a fresh twist.
Step 4: Stuff the Shells with the Ricotta Mixture

Now it’s time to bring it all together!
- Preheat your oven to 375°F (190°C).
- Spread about 1 cup of marinara sauce evenly on the bottom of a 9×13-inch baking dish.
- Using a spoon or piping bag, fill each cooked shell generously with the ricotta-spinach mixture.
- Arrange the filled shells seam-side up in the baking dish, nestled closely together.
You should have about 20–24 filled shells depending on the size of your pasta.
Pro Tip: Don’t overfill the shells — they’ll expand slightly as they bake and absorb some sauce.
Step 5: Assemble and Bake the Dish

With your shells stuffed and arranged, it’s time to layer and bake them into cheesy, bubbling perfection.
- Pour the remaining marinara sauce evenly over the stuffed shells. Make sure each one is coated — this keeps them moist during baking.
- Sprinkle the top with the extra mozzarella and Parmesan cheese.
- Cover the dish loosely with aluminum foil.
- Bake for 25 minutes, then remove the foil and bake for another 10–15 minutes until the cheese is melted and slightly golden.
When it’s done, the sauce should be bubbling around the edges and the aroma should fill your kitchen.
Optional: For an extra-crispy top, broil for 2–3 minutes after baking.
Step 6: Serve and Savor the Deliciousness
Once out of the oven, let the stuffed shells rest for 5–10 minutes before serving. This helps them set slightly and makes it easier to serve without falling apart.
Garnish with freshly chopped basil or parsley and a light drizzle of olive oil for a restaurant-worthy presentation.
Serving Suggestions:
- Pair with a crisp Caesar salad or garlic bread for a complete Italian-style dinner.
- Serve alongside a glass of Chianti or Pinot Noir for the perfect pairing.
- For a lighter touch, accompany with roasted vegetables or a side of steamed broccoli.
Storage Tip: These shells keep beautifully! Refrigerate leftovers for up to 4 days or freeze for up to 2 months. To reheat, cover with foil and bake at 350°F until heated through.
