Step‑by‑Step Instructions for Creamy Seafood Stuffed Shells
Step 1: Prepare the Seafood
In a large skillet over medium heat, melt 2 tablespoons of butter. Add 3 minced garlic cloves and sauté for about 1-2 minutes until fragrant. Stir in 1 cup each of diced lobster meat and crab meat, cooking for an additional 2-3 minutes until heated through. Once done, remove from heat and set the seafood mixture aside to cool slightly.
Step 2: Make the Filling
In a large mixing bowl, combine the seafood mixture with 8 oz of cream cheese and 1 cup of shredded mozzarella cheese. Use a spatula to mix everything until well combined. Season the filling with salt and pepper to taste, ensuring the flavors are balanced. This rich filling is the heart of your Creamy Seafood Stuffed Shells.
Step 3: Cook the Jumbo Shells
Bring a large pot of salted water to a boil and add 12 Jumbo pasta shells. Cook them according to package instructions until al dente, usually about 9-11 minutes. Drain the shells and immediately rinse them under cold water to stop the cooking process. Lay the shells gently on a clean kitchen towel to cool while you prepare the sauce.
Step 4: Prepare the Sauce
In the same skillet used for the seafood, melt 4 tablespoons of butter over medium heat. Once melted, sprinkle in 2 tablespoons of flour, stirring for 1-2 minutes until bubbly. Gradually whisk in 1 cup of heavy cream, continuing to stir until the sauce thickens, about 3-4 minutes. Add 1 cup of shredded mozzarella and ½ cup of grated Parmesan cheese, stirring until the cheeses melt and the mixture is smooth.
Step 5: Assemble the Dish
Preheat your oven to 375°F (190°C). Pour a thin layer of the cheese sauce into the bottom of a 9×13 inch baking dish, ensuring even coverage. Carefully stuff each jumbo shell with the creamy seafood filling, placing them seam-side up in the dish. Once all shells are stuffed, pour the remaining cheese sauce over them, making sure they are well covered.
Step 6: Bake
Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. After that time, remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown. The aroma of the creamy seafood stuffed shells will fill your kitchen as they bake to perfection.
Step 7: Serve
Once baked, remove the dish from the oven and let it cool for about 5 minutes before serving. This allows the flavors to settle. Garnish with extra grated Parmesan or fresh herbs if desired, and serve warm. The Creamy Seafood Stuffed Shells are ready to impress your family and friends with their rich flavors!

Make Ahead Options
These Creamy Seafood Stuffed Shells are perfect for busy home cooks looking to save time during the week! You can prepare the entire dish up to 24 hours in advance. Simply assemble the stuffed shells in the baking dish, cover tightly with plastic wrap, and refrigerate. To maintain quality, ensure your cheese sauce is poured over the shells to keep the pasta moist. When you’re ready to bake, remove the plastic wrap and pop it in the oven straight from the fridge, adding an extra 10-15 minutes to the baking time. This way, you’ll have a restaurant-quality dinner ready with minimal effort when it’s time to serve!

Creamy Seafood Stuffed Shells Recipe FAQs
What type of seafood is best for filling the shells?
Absolutely! For the best flavor, always opt for fresh lobster, crab, and shrimp. Fresh seafood provides a richer taste and better texture. If fresh ingredients aren’t available, you can use frozen seafood, but be sure to thaw them properly before cooking to avoid excess water.
How should I store leftovers of Creamy Seafood Stuffed Shells?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm them in the oven at 350°F (175°C) or in the microwave until heated through.
Can I freeze Creamy Seafood Stuffed Shells?
Yes! To freeze unbaked stuffed shells, place them in a single layer on a baking sheet for about an hour until solid.

When you’re ready to bake, go straight from the freezer to the oven, adding an extra 10-15 minutes to the baking time.
What can I do if my cheese sauce is too thick?
Don’t worry! If your cheese sauce is too thick, simply add a splash of heavy cream or milk to loosen it up. Keep whisking over low heat until you reach your desired consistency. If you’ve added too much liquid, just let it simmer a bit longer to thicken back up.
Can I make Creamy Seafood Stuffed Shells ahead of time?
Very much! You can prepare everything a day before and store the assembled shells in the refrigerator without baking them. When you’re ready to enjoy, just pop them in a preheated oven at 375°F (190°C) for about 30-35 minutes to cook through and achieve that bubbly, golden crust.
