Creamy Sun-Dried Tomato Spinach Stuffed Shells

Picture this: it’s a busy Tuesday, the kids are hungry, and you need something that feels special but doesn’t keep you chained to the stove. That’s where these Sun-Dried Tomato & Spinach Stuffed Shells come in – they’re like a warm hug in a baking dish, with a creamy, cheesy filling that’s studded with tangy sun-dried tomatoes and earthy spinach.

I’ve always believed that a great vegetarian dish should never make you miss the meat. These shells are so rich and satisfying that even the biggest carnivore at your table will be reaching for seconds. Plus, they’re surprisingly simple to put together – you’ll have them in the oven in about 20 minutes.

So grab your biggest pot, crank up the oven, and let’s make some magic. Trust me, the aroma alone will have everyone wandering into the kitchen asking, “What’s for dinner?”

About the Ingredients

12 oz (340g) jumbo pasta shells

About 30 shells. Use large shells that hold the filling well; if you can't find jumbo, use manicotti tubes.

2 cups (250g) ricotta cheese

Full-fat ricotta gives the creamiest texture; part-skim works too. For a dairy-free option, use a blend of blended tofu and cashews.

2 cups (200g) shredded mozzarella, divided

Freshly shredded melts better than pre-shredded (which has anti-caking agents). Use 1.5 cups in filling and 0.5 cup for topping.

1 cup (100g) grated Parmesan cheese, divided

Use real Parmigiano-Reggiano for the best flavor; add 3/4 cup to filling, reserve 1/4 cup for topping.

1 large egg, lightly beaten

Binds the filling. For an egg-free version, use 2 tablespoons of cornstarch mixed with 3 tablespoons water.

1 cup (200g) sun-dried tomatoes (oil-packed), drained and chopped

Oil-packed adds extra flavor; if using dry, rehydrate in hot water for 10 minutes. Reserve a bit of oil to brush the dish.

5 oz (140g) fresh spinach, roughly chopped

Baby spinach works great. If using frozen, thaw and squeeze out all excess moisture.

2 cloves garlic, minced

Fresh garlic is best; in a pinch, use 1 teaspoon of garlic powder.

1 teaspoon dried Italian seasoning

A blend of oregano, basil, and thyme. Substitute with 1/2 tsp each of dried oregano and basil.

1/2 teaspoon salt

Adjust to taste; if your sun-dried tomatoes are salty, you might need less.

1/4 teaspoon black pepper

Freshly ground is best.

3 cups (720ml) marinara sauce

Use your favorite jarred sauce, or homemade. Look for a lower-sugar option if you prefer.

Tips & Tricks

• Cook the shells 1-2 minutes less than package directions – they’ll finish cooking in the oven and won’t tear when stuffing.
• Squeeze the spinach very dry after cooking to avoid a watery filling.
• Use a piping bag or a zip-top bag with a corner snipped off to fill the shells quickly and neatly.
• If the filling feels too thick, add a tablespoon of milk or water to loosen it.

Step-by-Step Instructions

1. Preheat and prep

Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Spread 1 cup of marinara sauce on the bottom of a 9×13-inch baking dish.

2. Cook the shells

Boil the shells according to package directions, but 1-2 minutes less than al dente. Drain, rinse with cool water, and set aside on a baking sheet to stop cooking.

3. Sauté the aromatics

In a medium skillet over medium heat, add 1 tablespoon olive oil (or reserved sun-dried tomato oil). Sauté garlic for 30 seconds until fragrant, then add spinach and cook until wilted, about 2 minutes. Remove from heat and let cool slightly.

4. Make the filling

In a large bowl, combine ricotta, 1.5 cups mozzarella, 3/4 cup Parmesan, egg, sun-dried tomatoes, spinach mixture, Italian seasoning, salt, and pepper. Mix until well combined.

5. Stuff the shells

Spoon the filling into a piping bag or zip-top bag with a corner cut off. Pipe the filling into each shell, filling them generously (about 1 heaping tablespoon each). Place filled shells in the prepared dish, seam-side up.

6. Top and bake

Pour the remaining 2 cups of marinara sauce evenly over the shells. Sprinkle with the remaining 1/2 cup mozzarella and 1/4 cup Parmesan. Cover with foil and bake for 25 minutes. Remove foil and bake for an additional 10 minutes, or until the sauce is bubbly and the cheese is golden brown.

7. Rest and serve

Let the dish rest for 5 minutes before serving. Garnish with fresh basil or parsley if desired. Serve hot and enjoy!

Delicious Variations

Add a protein

Mix in 1 cup of cooked lentils or crumbled tofu to the filling for extra heartiness.

Go vegan

Use dairy-free ricotta, mozzarella, and Parmesan alternatives, and replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water).

Swap the greens

Use kale instead of spinach – just massage it with a little olive oil and lemon juice before cooking.
