These cheesy Spinach and Ricotta Stuffed Shells are fresh, flavourful and ultra-creamy. So satisfying and delicious, they’re everything you could want in a cozy vegetarian option for your next pasta night!

A comfort food classic, these saucy stuffed shells are absolutely packed with creamy ricotta, Parmesan and mozzarella, a rich marinara sauce, fresh herbs and leafy greens.

Here’s everything you’ll need to make these Spinach and Ricotta Stuffed Shells

• 1 cup (240 g) ricotta
• ¾ cup (90 g) shredded mozzarella
• ½ cup (40 g) freshly grated Parmesan
• 1 large egg
• 2 cups (60 g) chopped spinach
• 2 teaspoons (2 g) finely chopped fresh rosemary
• 1 teaspoon (1 g) finely chopped fresh sage
• 1/8 teaspoon (<1 g) nutmeg
• 3 cups (750 ml) quick homemade or store-bought tomato sauce
• 20-24 jumbo pasta shells or conchiglioni
• 1 cup (120 g) shredded mozzarella (optional)
• Fresh parsley to garnish

Made with loads of spinach, aromatic garlic, fresh rosemary and sage, this is a quick and easy-to-put-together meal you can feel good about. Simply assemble the filling while cooking the pasta according to package instructions. Drain the pasta then spoon the filling into the shells. Transfer them to the baking dish, top with more mozzarella and bake!

Do I need to cook the spinach?

Not at all, the spinach will have plenty of time to cook while the shells are baking. You can even make these Spinach & Ricotta Stuffed Shells with frozen spinach. First thaw it, then wrap it in a dry tea towel or paper towels and press to remove any excess water before adding it to the filling.

Tip: Boost plant protein by adding 1/3 cup chopped walnuts to the filling.

Make ahead

To prepare this meal in advance, assemble your pan and cover tightly with plastic wrap to keep the pasta nice and moist in the refrigerator for up to 3 days. Try dividing this recipe between two pans and freeze one once baked for future dinners!

Oh, and even better? The filling is no-cook and both the filling and tomato sauce can be prepared in advance, making these Spinach and Ricotta Stuffed Shells a quick, hearty and comforting meal to put together for an easy weekend dinner.

Instructions

• In a medium-sized mixing bowl, stir together all filling ingredients until combined and set aside.
• Cook shells according to package instructions. Drain, then spread them out on a baking sheet or cutting board to prevent them from sticking together.
• Preheat oven to 350°F (177ºC) and spread marinara across the bottom of a 9×13-inch baking pan. Stuff shells with equal amounts filling and place each filled shell into the pan on top of the sauce as you go.
• Sprinkle remaining mozzarella across the top, if using, and bake for 30 minutes. Optional: Once baked, place shells under broiler for 2 minutes keeping a close eye until the cheese is slightly browned and crispy. Garnish with fresh parsley, transfer to serving plates and enjoy!

Notes

Use frozen spinach: First thaw it, then wrap it in a dry tea towel or paper towels and press to remove any excess water before adding it to the filling.

Do I need to cook the spinach? Not at all, the spinach will have plenty of time to cook while the shells are baking!

Cooking the pasta: I always add 3 or 4 more shells to the pot than required for this recipe in case any should break while cooking.

Make ahead: To have this meal ready ahead of time, assemble your pan and cover tightly with plastic wrap to keep pasta nice and moist in the refrigerator for up to 3 days. Try dividing this recipe between two pans and freeze one once baked for future dinners!

Storage: Leftovers can be stored in a well-sealed container in the refrigerator for up to 5 days or frozen for up to 3 months. To reheat, bring to room temperature then return to 350ºF (177ºC) oven and reheat for 10-15 minutes (from the fridge) or 20-30 minutes if previously frozen until warmed through.
