Here’s everything you’ll need to make these Ultra-Creamy Spinach and Ricotta Stuffed Shells
- 1 cup (240 grams) ricotta
- ¾ cup (90 grams) shredded mozzarella
- ½ cup (40 grams) freshly grated Parmesan
- 1 large egg
- 2 cups (60 grams) chopped spinach
- 2 teaspoons (2 grams) finely chopped fresh rosemary
- 1 teaspoon (1 gram) finely chopped fresh sage
- 1/8 teaspoon (<1 gram) nutmeg
- 3 cups (750 ml) quick homemade or store-bought tomato sauce
- 20-24 jumbo pasta shells or conchiglioni
- 1 cup (120 grams) 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.
Can I make these stuffed shells with frozen spinach?
Yes. 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.
My favorite cooking tip
Boost plant protein by adding 1/3 cup chopped walnuts to the filling!
A Great Make-Ahead Option
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.
