Ingredients
- 12 jumbo pasta shells
- 225 g (8 oz) cooked shrimp, finely chopped
- 225 g (8 oz) crab meat (lump or claw), well drained
- 250 ml (1 cup) ricotta cheese, whole milk preferred
- 125 ml (½ cup) grated Parmesan cheese, plus extra for topping
- 250 ml (1 cup) shredded mozzarella cheese, plus extra for topping
- 1 clove garlic, minced very finely
- 5 ml (1 tsp) fresh lemon zest
- 30 ml (2 tbsp) fresh parsley, finely chopped
- Salt and freshly ground black pepper, to taste
- 30 g (2 tbsp) unsalted butter
- 30 g (2 tbsp) all-purpose flour
- 375 ml (1 ½ cups) whole milk (or 2%)
- 125 ml (½ cup) heavy cream
- 2.5 ml (½ tsp) freshly grated nutmeg (optional, but recommended)
- Salt and freshly ground white pepper, to taste
- Olive oil, for drizzling
- Optional Toppings: Extra shredded mozzarella or Parmesan for baking, fresh parsley or basil for garnish, lemon wedges for serving
Instructions
- Preheat your oven to 190°C (375°F). Lightly grease a 9×13-inch (approx. 23×33 cm) baking dish with butter or a non-stick cooking spray to prevent sticking and ensure even browning.
- Bring a large pot of generously salted water to a rolling boil. Add the jumbo pasta shells and cook according to package directions until they are slightly undercooked, or 'al dente'. This ensures they hold their shape during stuffing and finish cooking in the oven without becoming mushy. Drain the shells thoroughly and immediately drizzle them with a small amount of olive oil, gently tossing to prevent them from sticking together. Set aside.
- Begin preparing the luxurious creamy sauce. In a medium-sized saucepan, melt the butter over medium heat until it's foamy. Whisk in the all-purpose flour and cook for 1–2 minutes, stirring continuously, to create a 'roux'. This step is crucial for removing any raw flour taste and developing a nutty flavor. Gradually pour in the milk and heavy cream, whisking constantly to prevent lumps from forming. Continue to cook, whisking, until the sauce thickens to a consistency that coats the back of a spoon. Season the béchamel with salt, white pepper, and the optional (but highly recommended) nutmeg. Remove the sauce from the heat and set aside.
- Prepare the decadent seafood filling. In a large mixing bowl, combine the chopped cooked shrimp, well-drained crab meat, ricotta cheese, grated Parmesan cheese, shredded mozzarella cheese, minced garlic, fresh lemon zest, and chopped fresh parsley. Season generously with salt and freshly ground black pepper. Stir all the ingredients together gently until they are thoroughly combined, being careful not to break up the crab meat too much if using lump crab.
- Carefully spoon the prepared seafood filling into each cooked pasta shell. Aim for an even amount in each shell, ensuring they are well-filled but not overstuffed, which could cause them to burst during baking. Arrange the stuffed shells snugly in a single layer within your prepared baking dish.
- Evenly pour the creamy béchamel sauce over the arranged stuffed shells, ensuring each shell is well coated. For an extra golden crust and cheesy pull, sprinkle additional shredded mozzarella or Parmesan cheese over the top of the sauced shells.
- Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 15 minutes. This initial baking period allows the shells to finish cooking and the flavors to meld without the cheese browning too quickly. After 15 minutes, remove the foil and continue to bake for an additional 5–10 minutes, or until the cheese on top is beautifully golden brown and bubbly.
- Once baked, remove the dish from the oven and let it rest for a few minutes before serving. Garnish the dish generously with freshly chopped parsley or basil, which adds a bright, herbaceous note and a pop of color. Serve hot with fresh lemon wedges on the side for an optional squeeze of citrus that brightens the rich flavors. Complement this dish with crusty garlic bread or a crisp green salad.

Tools You’ll Need
- Large stockpot for pasta
- Medium saucepan for sauce
- Large mixing bowl
- 9×13-inch (23×33 cm) baking dish
- Whisk
- Spoon or small scoop for filling shells
- Measuring cups and spoons
- Cutting board and knife for chopping
Essential Success Tips
- Do not overcook the pasta shells during the initial boil; they should be firm enough to handle and finish cooking in the oven.
- Ensure your crab meat is very well-drained to prevent the filling from becoming watery, which can affect texture and flavor.
- Whisk continuously when making the béchamel sauce to ensure it is smooth and lump-free, gradually adding the milk and cream.
- Season the seafood filling and the sauce generously. Taste as you go, adjusting salt and pepper to your preference.
- Allow the finished dish to rest for a few minutes after baking; this helps the sauce settle and prevents it from being too runny when served.
Professional Cooking Secrets
- For an even richer sauce, infuse your milk with aromatics like a bay leaf and a few black peppercorns before adding to the roux; strain before using.
- Add a splash of dry white wine (like Pinot Grigio or Sauvignon Blanc) to your béchamel after whisking in the flour, allowing it to reduce for a minute before adding milk, for an extra layer of sophisticated flavor.
- Always finish baked pasta dishes with a squeeze of fresh lemon juice just before serving. The acidity brightens the heavy, rich flavors and elevates the entire dish.

Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
- Freezing Instructions: Unbaked stuffed shells can be assembled in a freezer-safe dish (without the creamy sauce poured over) and frozen for up to 2 months. Thaw overnight in the refrigerator, then prepare the sauce, pour over, and bake as directed, adding an extra 10-15 minutes to the covered baking time.
- Variations: Feel free to add 125 ml (½ cup) of cooked, well-drained, and chopped spinach to the seafood filling for added color and nutrition. You can also experiment with different types of seafood like bay scallops or firm white fish, ensuring they are cooked and chopped appropriately.
Frequently Asked Questions
Can I prepare this dish ahead of time?
Yes, you can assemble the stuffed shells in the baking dish and prepare the sauce up to one day in advance. Store them separately in the refrigerator. When ready to bake, pour the sauce over the shells and proceed with baking as directed, potentially adding a few extra minutes to the initial covered baking time if baking from cold.
What kind of crab meat is best for this recipe?
For the best texture and presentation, lump crab meat is ideal as it provides substantial pieces. However, claw crab meat works well too, offering a more robust crab flavor and often being more budget-friendly. Just ensure it's thoroughly drained regardless of the type.
Can I make this recipe gluten-free?
Absolutely! To make this dish gluten-free, substitute the jumbo pasta shells with gluten-free jumbo shells (ensure they hold their shape) and use a gluten-free all-purpose flour blend for the creamy sauce. The rest of the ingredients are naturally gluten-free.
