Shrimp and Crab Stuffed Shells with Alfredo Sauce
Jumbo pasta shells stuffed with sweet crab meat, tender shrimp, and creamy ricotta, baked under a rich, velvety alfredo sauce until golden and bubbly.
A Seafood Lover's Dream Dinner
There is something irresistible about cracking into a pasta shell and finding it packed with sweet crab meat and tender shrimp, all blanketed in a rich, garlicky alfredo sauce. These Shrimp and Crab Stuffed Shells with Alfredo Sauce take the cozy comfort of classic stuffed shells and dress them up for date night, holidays, or any time you want dinner to feel a little special. It is the kind of dish that looks like it took hours, but really comes together with a few simple steps.
If you love the combination of seafood and pasta, this recipe checks every box. The jumbo pasta shells hold their shape beautifully, the ricotta filling stays light instead of dense, and the alfredo sauce ties it all together without overpowering the delicate crab and shrimp flavors.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy baking dish helps the shells bake evenly without drying out, and using good quality crab meat and fresh shrimp instead of pre-cooked, frozen versions makes a noticeable difference in texture and flavor. A few kitchen basics, like a sharp paring knife for deveining shrimp and a sturdy whisk for the sauce, will make the whole process smoother.
Choosing Your Seafood
The quality of your shrimp and crab meat really shines through in this dish, so it is worth choosing carefully.
- Shrimp: Use raw, peeled, and deveined shrimp for the best texture. Medium to large shrimp work well chopped into bite sized pieces.
- Crab meat: Lump crab meat offers the best balance of texture and sweetness. Claw meat is a more budget friendly option with a slightly stronger flavor.
- Imitation crab: A reasonable substitute if fresh crab is unavailable, though the flavor will be milder and a bit sweeter.
Chef's Tip: Resist the urge to fully cook the shrimp before stuffing the shells. A quick sear just until opaque is all you need, since the shrimp will finish cooking gently in the oven under the sauce.
Building the Filling
The filling for these stuffed pasta shells is where all the magic happens. Creamy ricotta cheese acts as the base, binding the seafood together without masking it, while shredded mozzarella and parmesan add richness and that irresistible cheese pull. A touch of lemon juice brightens the whole mixture, and a small pinch of red pepper flakes adds warmth without making the dish spicy.
When mixing the filling, fold gently rather than stirring vigorously. You want to see distinct pieces of crab and shrimp in every bite, not a uniform paste. This is what makes these stuffed shells feel luxurious rather than like a typical baked pasta.
The Alfredo Sauce That Pulls It All Together
A homemade alfredo sauce is simpler than most people expect, and it makes all the difference compared to a jarred version. Butter and garlic form the fragrant base, heavy cream provides the silky body, and freshly grated parmesan thickens everything into a glossy, clingy sauce. Spooning a layer underneath the shells keeps them from sticking, while the layer on top bakes into a bubbly, golden finish.

Shrimp and Crab Stuffed Shells with Alfredo Sauce
Jumbo pasta shells stuffed with sweet crab meat, tender shrimp, and creamy ricotta, baked under a rich, velvety alfredo sauce until golden and bubbly.
Ingredients
- 24 jumbo pasta shells, about 12 oz, cooked al dente
- 1 lb shrimp, peeled, deveined, and chopped into small pieces
- 8 oz lump crab meat, picked over for shells
- 1 1/2 cups ricotta cheese, whole milk
- 1 1/2 cups shredded mozzarella cheese, divided
- 1/2 cup grated parmesan cheese, plus extra for topping
- 1 large egg, lightly beaten
- 3 cloves garlic, minced, divided
- 3 tbsp fresh parsley, chopped, divided
- 4 tbsp unsalted butter, divided
- 2 cups heavy cream
- 1 tbsp olive oil, for searing shrimp
- 1/2 lemon, juiced
- 1 tsp salt, or to taste
- 1/2 tsp black pepper, freshly cracked
- 1/4 tsp red pepper flakes, optional, for the filling
Instruction
Bring a large pot of salted water to a boil and cook the jumbo pasta shells until just al dente, about 9 to 10 minutes. Drain and lay them out on a sheet pan so they do not stick together.
While the pasta cooks, heat the olive oil and 1 tablespoon of butter in a skillet over medium heat. Add the chopped shrimp with a pinch of salt and pepper and cook for 2 to 3 minutes, just until opaque and pink. Remove from heat and let cool slightly.
In a large bowl, combine the cooked shrimp, crab meat, ricotta, 1 cup of the mozzarella, parmesan, beaten egg, 2 cloves of minced garlic, 2 tablespoons of parsley, lemon juice, salt, pepper, and red pepper flakes. Mix gently to keep the crab and shrimp chunky.
Preheat the oven to 375 degrees F (190 degrees C). Spread a thin layer of alfredo sauce (see next step) across the bottom of a 9x13 inch baking dish.
Make the alfredo sauce: melt the remaining 3 tablespoons of butter in a saucepan over medium heat. Add the remaining minced garlic and cook for 30 seconds until fragrant. Pour in the heavy cream and bring to a gentle simmer. Whisk in the parmesan until smooth and let thicken for 3 to 4 minutes. Season with salt and pepper.
Spoon or pipe the shrimp and crab filling into each pasta shell, arranging them snugly in the prepared baking dish.
Pour the remaining alfredo sauce evenly over the stuffed shells, then sprinkle the remaining mozzarella cheese on top.
Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake for another 8 to 10 minutes, until the sauce is bubbling and the cheese is golden in spots.
Let the dish rest for 5 minutes, then garnish with the remaining fresh parsley before serving.

Notes
Serving Suggestions
These stuffed shells are rich and satisfying on their own, but they pair beautifully with something bright on the side. Consider serving them with:
- A simple arugula salad with lemon vinaigrette
- Garlic roasted broccolini
- Warm, crusty bread for soaking up extra alfredo sauce
- A crisp glass of white wine, such as Pinot Grigio or Sauvignon Blanc
Storage and Reheating
Leftover stuffed shells keep well in the refrigerator for up to three days when stored in an airtight container. To reheat without drying out the seafood, cover the dish with foil and warm it in a 325 degree F oven until heated through, or microwave individual portions in short intervals.
Chef's Tip: This dish does not freeze particularly well once baked, since the cream sauce and delicate seafood can change texture. If you want to plan ahead, freeze the assembled, unbaked shells instead, then thaw overnight in the fridge before baking.
Why You Will Make This Again
Between the sweet crab, tender shrimp, and that glossy homemade alfredo sauce, these stuffed shells deliver restaurant quality flavor without requiring restaurant level effort. Whether you are making them for a special occasion or simply craving something a little indulgent on a weeknight, this recipe earns its spot in your regular rotation. Once you taste that first creamy, seafood packed bite, it is easy to see why this combination works so well.
