- 2 garlic cloves, minced or grated
- 1 teaspoon dried oregano
- 1 teaspoon lemon zest (from about ½ lemon)
- ¼ teaspoon red pepper flakes
- ¾ teaspoon sea salt
- Freshly ground black pepper to taste
- 1 large egg (optional, helps bind filling)
For Assembly:
- 2½-3 cups marinara sauce, divided
- ½ cup shredded mozzarella cheese (optional, for topping)
- Fresh basil or parsley for garnish

- Steamer basket or large skillet
- Colander
- 9×13-inch baking dish
- Medium mixing bowl
- Large spoon or small cookie scoop
- Aluminum foil
- Kitchen towel
How to Make Christmas Stuffed Shells
Step 1: Preheat Oven
Preheat your oven to 425°F (220°C).
Step 2: Cook the Spinach
Place fresh spinach in a steamer basket set over a pot with 1 inch of simmering water. Cover and steam for 1-2 minutes until completely wilted.
Stovetop Alternative: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add spinach and cook, stirring, until wilted (2-3 minutes).
Transfer wilted spinach to a clean kitchen towel or strainer. Let cool slightly, then squeeze out as much liquid as possible—this is important to prevent watery filling. Chop the spinach finely and set aside.
Step 3: Cook the Pasta Shells
Bring a large pot of salted water to a rolling boil. Add the jumbo shells and cook for 9-10 minutes until al dente (slightly underdone—they’ll finish cooking in the oven). Drain and rinse with cool water to stop the cooking. Drizzle with olive oil and toss gently to prevent sticking. Lay them out in a single layer on a baking sheet.
Pro Tip: Cook 2-3 extra shells in case some break!
Step 4: Make the Filling
In a medium bowl, combine the chopped spinach, ricotta cheese, Pecorino Romano, minced garlic, oregano, lemon zest, red pepper flakes, salt, and several grinds of black pepper. If using, add the egg and mix until everything is well combined. The mixture should be creamy and spreadable.
Taste and adjust seasoning as needed—it should be well-seasoned since the pasta shells are plain.
Step 5: Assemble the Dish
Spread 1½ cups of marinara sauce evenly across the bottom of a 9×13-inch baking dish.
Using a spoon or small cookie scoop, fill each pasta shell with about 2-3 tablespoons of the ricotta mixture. Arrange the stuffed shells in the baking dish, nestling them into the sauce. They can be placed close together.
Once all shells are filled and arranged, spoon the remaining marinara sauce over the top of the shells. If using mozzarella, sprinkle it over the top. Add extra Pecorino Romano if desired.
Step 6: Bake
Cover the baking dish tightly with aluminum foil. Bake for 20 minutes covered. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly and the shells are heated through.
Step 7: Garnish and Serve
Remove from the oven and let rest for 5 minutes. Garnish with fresh chopped parsley or basil. Serve hot with extra marinara sauce and grated cheese on the side.
Tips for Perfect Stuffed Shells
Don’t Overcook the Shells: Cook them al dente (slightly underdone). They’ll finish cooking in the oven and won’t get mushy.
Squeeze Spinach Thoroughly: Excess water makes the filling runny. Really squeeze hard to remove all moisture!
Season Generously: The filling should taste well-seasoned on its own since the pasta shells are plain.
Handle Shells Gently: Cooked shells are delicate. Rinse with cool water to stop cooking and handle carefully to prevent tearing.
Use Quality Ricotta: Whole milk ricotta creates the creamiest, most flavorful filling.
Add an Egg: For firmer filling that holds together better, add 1 beaten egg to the mixture.

Frequently Asked Questions
Can I use frozen spinach?
Yes! Use 10 ounces frozen chopped spinach. Thaw completely and squeeze out ALL liquid—frozen spinach holds a lot of water.

You either overcooked them or handled them roughly. Cook al dente and handle gently. Always cook a few extra shells as backup.
Can I make this ahead?
Absolutely! Assemble completely, cover, and refrigerate up to 24 hours. Bake when ready, adding 10 minutes to cooking time.
My filling is watery. What happened?
The spinach wasn’t squeezed dry enough. Really squeeze hard to remove all moisture. You can also add an egg to help bind the filling.

Do I have to use ricotta?
Ricotta is traditional, but cottage cheese (blended smooth) or mascarpone can work as substitutes.
How do I know when they’re done?
The cheese should be bubbly, the sauce should be hot, and the shells should be tender. If you inserted a knife, it should go through easily.
