Shrimp and Crab Stuffed Shells with Alfredo Sauce
Jumbo pasta shells stuffed with a creamy shrimp and crab ricotta filling, smothered in rich homemade alfredo sauce and baked until bubbly and golden.
A Seafood Lover's Dream Dinner
There is something undeniably special about pulling a dish of shrimp and crab stuffed shells out of the oven, bubbling under a blanket of golden mozzarella and rich alfredo sauce. This recipe takes everything wonderful about classic stuffed shells and turns the volume up with sweet lump crab meat and tender shrimp folded into a creamy ricotta filling. It is the kind of meal that looks like it took hours of restaurant level effort, but comes together with surprisingly simple steps in your own kitchen.
Whether you are cooking for a special occasion, a Sunday family dinner, or just because you deserve something indulgent on a Tuesday night, this dish delivers every time.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy large pot for boiling the jumbo pasta shells without tearing them, a reliable whisk for a silky lump free alfredo sauce, and good quality lump crab meat are what separate an okay stuffed shells recipe from an unforgettable one.
Choosing the Best Crab Meat and Shrimp
The seafood is truly the star of this dish, so it is worth choosing well. Fresh or refrigerated lump crab meat, often found near the seafood counter, tends to have the sweetest flavor and best texture for stuffing. If you are working with a tighter budget, imitation crab is a completely reasonable substitute and still tastes fantastic once mixed with ricotta and parmesan.
For the shrimp, medium to large shrimp work best. Chopping them into smaller pieces after a quick sauté helps them distribute evenly throughout the filling in every single bite.
Chef's Tip: Do not overcook the shrimp in the skillet. Since they will bake again in the oven, pulling them off the heat while still slightly underdone keeps them tender instead of rubbery once the dish is finished baking.
Getting the Filling Just Right
The filling is a simple mixture of ricotta cheese, mozzarella, parmesan, egg, and your cooked shrimp and crab meat, brightened with a touch of lemon juice and fresh parsley. The egg helps bind everything together so the filling holds its shape inside each jumbo pasta shell instead of oozing out during baking.
A few tips that make a real difference:
- Let the cooked shrimp cool slightly before mixing so it does not melt the ricotta.
- Fold the crab meat in gently to keep those beautiful lump pieces intact.
- Taste the filling before stuffing and adjust the salt, since crab and shrimp can vary in natural saltiness.
Once your filling is ready, stuffing the stuffed pasta shells is genuinely one of the more relaxing parts of the process. A small spoon or piped filling using a zip top bag with the corner snipped off makes quick work of it.
The Alfredo Sauce That Ties It All Together
No stuffed shells dish is complete without a luscious alfredo sauce, and this one comes together in just minutes on the stovetop. Butter, garlic, heavy cream, and freshly grated parmesan simmer together until silky and slightly thickened, ready to be poured generously over your stuffed shells before baking.
Chef's Tip: Use freshly grated parmesan rather than the pre-shredded kind for the smoothest, creamiest alfredo sauce. Pre-shredded cheese contains anti-caking agents that can make the sauce slightly grainy.

Shrimp and Crab Stuffed Shells with Alfredo Sauce
Jumbo pasta shells stuffed with a creamy shrimp and crab ricotta filling, smothered in rich homemade alfredo sauce and baked until bubbly and golden.
Ingredients
- 24 jumbo pasta shells, about 12 oz, cooked al dente
- 1 lb shrimp, peeled, deveined, and chopped
- 8 oz lump crab meat, picked over for shells
- 1 1/2 cups ricotta cheese, whole milk
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup grated parmesan cheese, plus more for topping
- 1 large egg, lightly beaten
- 3 cloves garlic, minced, divided
- 4 tbsp unsalted butter, divided
- 1 1/2 cups heavy cream
- 2 tbsp fresh parsley, chopped, plus more for garnish
- 1 tbsp lemon juice, freshly squeezed
- 1 tsp salt, or to taste
- 1/2 tsp black pepper, freshly cracked
- 1/4 tsp red pepper flakes, optional, for the filling
Instruction
Preheat the oven to 375 degrees F (190 degrees C) and lightly grease a 9x13 inch baking dish.
Bring a large pot of salted water to a boil and cook the jumbo pasta shells until just al dente, about 1 to 2 minutes less than the package directs. Drain and lay flat on a sheet pan to cool.
In a skillet, melt 1 tablespoon of butter over medium heat. Add the chopped shrimp and half the minced garlic, and cook for 2 to 3 minutes until the shrimp is just pink and opaque. Remove from heat and let cool slightly.
In a large bowl, combine the cooked shrimp, crab meat, ricotta, 1 cup of the mozzarella, parmesan, egg, parsley, lemon juice, salt, black pepper, and red pepper flakes. Stir gently until evenly combined, being careful not to break up the crab too much.
To make the alfredo sauce, melt the remaining 3 tablespoons of butter in a saucepan over medium heat. Add the remaining garlic and cook for 30 seconds until fragrant.
Pour in the heavy cream and bring to a gentle simmer. Whisk in the remaining parmesan and simmer for 3 to 4 minutes until the sauce thickens slightly. Season with salt and pepper to taste.
Spread a thin layer of alfredo sauce across the bottom of the prepared baking dish.
Carefully spoon the shrimp and crab filling into each pasta shell, about 1.5 to 2 tablespoons per shell, and arrange them in the baking dish.
Pour the remaining alfredo sauce evenly over the stuffed shells, then sprinkle with the remaining 1 cup of mozzarella.
Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for another 10 to 15 minutes until the sauce is bubbling and the cheese is golden.
Let rest for 5 minutes, then garnish with fresh parsley before serving.

Notes
Serving, Storing, and Make-Ahead Tips
This dish pairs beautifully with a simple green salad, garlic bread, or steamed asparagus to round out the meal. A glass of crisp white wine, like a Pinot Grigio or unoaked Chardonnay, complements the richness of the alfredo and sweetness of the seafood wonderfully.
If you want to get ahead of dinner, this recipe is very make-ahead friendly. Assemble everything up to a day in advance, cover tightly, and refrigerate until you are ready to bake. Leftovers store well too, keeping nicely in the fridge for a few days and reheating beautifully with a splash of cream to bring the sauce back to life.
However you serve it, this shrimp and crab stuffed shells recipe is destined to become one of those dishes people ask you to make again and again.
