Step‑by‑Step Instructions for Creamy Seafood Stuffed Shells
Step 1: Prep Pasta
Begin by cooking the large pasta shells in boiling salted water according to the package instructions, usually 9–11 minutes until al dente. Once done, drain them and rinse under cool water to halt the cooking process. Set the shells aside, ensuring they don’t stick together as you prepare the creamy filling.
Step 2: Make Filling
In a large mixing bowl, combine the chopped seafood—such as prawns and crab—with softened cream cheese and your choice of seasonings. Stir until all ingredients are evenly mixed, taking care to create a smooth and cohesive filling. This delightful mixture is the heart of your Creamy Seafood Stuffed Shells, so ensure it’s well blended.
Step 3: Prepare Sauce
Melt 4 tablespoons of butter in a medium saucepan over medium heat. Add minced garlic and chopped onion, sautéing until fragrant, about 2-3 minutes. Gradually whisk in flour, cooking for another minute. Slowly add milk, continuously stirring until the sauce thickens, then incorporate cheddar cheese until fully melted and smooth.
Step 4: Assemble Shells
Preheat your oven to 180°C (160°C Fan). Take each large shell and gently spoon the seafood mixture inside, filling generously but avoiding overflow. Arrange the stuffed shells in a greased baking dish, spacing them evenly. Pour the creamy cheese sauce generously over the shells, ensuring they are well-covered for delightful moisture during baking.
Step 5: Bake
Cover the baking dish with foil and bake in the preheated oven for 25-30 minutes. You’ll know the Creamy Seafood Stuffed Shells are ready when they are heated through and the sauce is bubbling around the edges. Remove the foil for the last 5 minutes if you desire a golden top, enhancing the appeal of this elegant dish.

Expert Tips for Creamy Seafood Stuffed Shells

Make-Ahead Magic: You can prepare these Creamy Seafood Stuffed Shells a day in advance. Just add extra baking time if they go into the oven straight from the fridge.
