Spinach and ricotta stuffed shells are pure comfort and always a favorite for family dinners. The creamy ricotta mixed with bright spinach and garlic gets tucked into tender pasta shells and baked under bubbling marinara. This recipe balances cozy, cheesy flavors with the fresh lift of homemade filling. It is a dish that always brings everyone to the table with anticipation.
The first time I made these shells I doubled the batch and popped half in the freezer. My family ended up loving them so much we polished off both pans in one weekend. Now this is my top pick for casual gatherings.
Ingredients
- Jumbo pasta shells: These are the base and perfect for stuffing. Look for shells that are not cracked or broken for easy filling
- Ricotta cheese: Creamy and mild this is the heart of the filling. Choose full fat for the richest flavor
- Mozzarella cheese: Melts beautifully and gives a stretchy cheesy top. Shred your own for best taste
- Parmesan cheese: Nutty and salty this pulls the filling together. Buy a block and grate fresh if possible
- Large egg: Helps the filling hold its shape and adds richness. Check for no cracks when buying eggs
- Fresh spinach or frozen spinach: Adds color and nutrients with a mild earthy flavor. Use fresh if you can but frozen also works well
- Garlic: Brings aroma and depth. Use fresh cloves that are firm and not sprouting
- Marinara sauce: Brings tomato sweetness and moisture. Go for a brand with simple ingredients or use homemade
- Olive oil: For sautéing and extra flavor. Use extra virgin for the most aroma
- Italian seasoning: Delivers classic herb notes. Check that your blend is fresh for the fullest taste
- Salt and freshly ground black pepper: Lifts the other flavors and balances the dish
- Fresh basil leaves for garnish: Add color and a final burst of freshness. They are optional but beautiful
Step-by-Step Instructions
- Cook the Pasta Shells:
- Bring a large pot of salted water to a rolling boil. Gently add the shells and cook them until they are just al dente which usually takes about 8 to 10 minutes. Drain them immediately and run them under cool water to stop the cooking. This prevents them from sticking and helps keep a nice shape for stuffing
- Make the Filling:
- In a large mixing bowl combine ricotta cheese half of the mozzarella Parmesan cheese and egg. Mix everything thoroughly until smooth and well blended. To cook the spinach heat olive oil in a skillet over medium heat. Add garlic and cook briefly until fragrant about 30 seconds. Stir in chopped spinach and sauté until wilted about 2 to 3 minutes. Let this cool slightly before mixing it into the cheese filling. Season with Italian seasoning salt and pepper
- Stuff the Shells:
- Preheat the oven to 375 degrees Fahrenheit. Lightly coat a baking dish with a little olive oil or cooking spray. Spread a layer of marinara sauce on the bottom of the dish. Carefully fill each cooked shell with the ricotta spinach mixture using about two tablespoons per shell. Arrange the shells in the dish open side up so the filling is visible
- Bake the Shells:
- Spoon the remaining marinara sauce over the stuffed shells making sure they are covered but not swimming. Sprinkle over the remaining mozzarella for a cheesy top. Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake for another 10 minutes so the cheese melts and the top turns golden. Let the shells rest for a few minutes before serving to set the filling and let flavors develop

Spinach is the star of this dish for me because its subtle flavor works with the ricotta and cheese to make each bite creamy but fresh. I remember making these shells for my mom on her birthday and watching everyone take seconds because they loved that homemade touch.
Storage Tips
Stuffed shells keep well in the refrigerator for up to four days stored in an airtight container. If you want to freeze them just assemble the dish but hold off on baking. Cover tightly with foil and freeze up to two months. To reheat bake straight from the fridge covered with foil or microwave individual portions until hot all the way through.
Ingredient Substitutions
If you are out of ricotta try cottage cheese blended smooth for a similar texture. Kale or chard can take the place of spinach if you want a bolder flavor. You can swap marinara with your favorite tomato sauce or even a creamy Alfredo for a twist. Lactose free mozzarella or Parmesan works well if needed.
Serving Suggestions
These shells shine alongside a crisp green salad with a simple vinaigrette. Add a slice of garlic bread for soaking up extra sauce. When making dinner for friends I like to offer roasted vegetables or a lemony asparagus on the side to lighten up the meal. A glass of chilled white wine turns it into an occasion.
Cultural and Historical Context
Pasta shells stuffed with cheese and greens have roots in Southern Italy where using seasonal greens with cheese in baked dishes is a tradition. The American version highlights plenty of melty cheese and sauce for added comfort perfect for family style meals and sharing at the table. This recipe brings a bit of Italian warmth to the everyday kitchen.
