Ingredients for this Seafood Stuffed Shells
- 20 jumbo pasta shells
- 1/2 pound shrimp, peeled, deveined, and chopped
- 1/2 pound lump crab meat
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 egg
- 2 tablespoons fresh parsley, chopped
- 1 teaspoon garlic powder
- Salt and black pepper to taste
For the Sauce:
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk (whole preferred)
- 1/2 cup grated Parmesan cheese
- 1/4 teaspoon ground nutmeg
- Salt and pepper to taste
For the Topping:
- 1/2 cup breadcrumbs
- 2 tablespoons melted butter
- Extra Parmesan for sprinkling

Step 1: Cook the Pasta Shells
Bring a large pot of salted water to a boil. Cook the pasta shells until just al dente, about 9 minutes. Drain and rinse with cold water to stop the cooking. Set aside.
Step 2: Prepare the Seafood Filling
In a large bowl, combine chopped shrimp, crab meat, ricotta, mozzarella, Parmesan, egg, parsley, garlic powder, salt, and pepper. Mix until fully incorporated. Set aside.
Step 3: Make the Béchamel Sauce
In a medium saucepan over medium heat, melt the butter. Stir in flour and cook, whisking constantly for 1-2 minutes until a paste forms. Gradually whisk in milk and cook until the sauce thickens, about 5 minutes. Stir in Parmesan cheese, nutmeg, and season with salt and pepper. Remove from heat.
Step 4: Stuff the Shells
Preheat oven to 375°F (190°C). Spoon the seafood filling into each cooked shell. Place the filled shells in a greased baking dish.
Step 5: Assemble the Dish
Pour the béchamel sauce evenly over the stuffed shells. In a small bowl, mix breadcrumbs with melted butter. Sprinkle breadcrumb mixture and additional Parmesan over the top.
Step 6: Bake to Perfection
Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes until the top is golden and bubbling.
Storage Instructions
Let the stuffed shells cool completely before storing. Place leftovers in an airtight container and refrigerate for up to 3 days. To reheat, cover with foil and bake at 350°F (175°C) until warmed through, or microwave individual portions.
To freeze, arrange stuffed shells (before baking) in a single layer on a baking sheet and freeze until solid. Transfer to a freezer-safe container or zip-top bag. Bake from frozen at 375°F (190°C) for 45–50 minutes, covered, until hot and bubbly.
