Step‑by‑Step Instructions for Seafood Stuffed Shells
Step 1: Prepare the Seafood
In a skillet over medium heat, melt 1 tablespoon of butter and sauté 2 cloves of minced garlic for about 1 minute until fragrant. Add 1 cup each of lobster and crab meat, stirring gently for 2-3 minutes, just until warmed through. The seafood should be tender and white, then remove from heat to cool slightly as you prepare the filling.
Step 2: Make the Filling
In a large mixing bowl, combine the sautéed seafood with 8 ounces of cream cheese, 1 cup of shredded mozzarella, and a pinch of salt and pepper. Stir well until all ingredients are fully integrated and creamy. You’ll want a smooth consistency for easy filling of the jumbo shells. Set aside while you prepare the pasta.
Step 3: Cook the Jumbo Shells
Bring a large pot of salted water to a boil. Add 12 jumbo pasta shells and cook according to package instructions, typically about 9-11 minutes, until al dente. Drain carefully and let the shells cool in a colander, ensuring they don’t stick together as you prepare the cheese sauce.
Step 4: Prepare the Sauce
In the same skillet used for the seafood, melt 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons of flour, cooking for about 1 minute until golden. Gradually pour in 1 cup of heavy cream while continuing to whisk, ensuring no lumps remain. Stir in another 1 cup of shredded mozzarella and ½ cup of grated Parmesan until the sauce is smooth and bubbling.
Step 5: Assemble the Dish
Preheat your oven to 375°F (190°C). Spread a layer of cheese sauce across the bottom of a baking dish. Carefully fill each jumbo shell with the seafood mixture and place them seam-side up in the dish. Pour the remaining cheese sauce generously over the filled shells, making sure to cover them well.
Step 6: Bake
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes, then carefully remove the foil and continue baking for an additional 10 minutes, or until the edges are bubbly and the top is golden brown. The cheese should be deliciously melted and slightly crisped.
Step 7: Serve
Once out of the oven, let the Seafood Stuffed Shells cool for about 5 minutes. Garnish with extra parsley or Parmesan, if desired, before serving warm. The comforting aroma will beckon everyone to the table, making for an inviting dining experience.

Make Ahead Options
These Seafood Stuffed Shells are a fantastic choice for meal prep, allowing you to save time on busy evenings! You can prepare the filling and fill the shells up to 24 hours in advance. Simply cover the assembled dish with foil and refrigerate before baking. When it’s time to enjoy, preheat your oven and bake directly from the fridge; you may need to add an extra 5-10 minutes to the cooking time to ensure they are heated through. To maintain their delicious quality, avoid overcooking the shells, which can lead to a rubbery texture. With this make-ahead strategy, you’ll have a comforting, restaurant-quality meal on the table with minimal effort!

Seafood Stuffed Shells Recipe FAQs
What kind of seafood should I use?
Absolutely! Fresh seafood is recommended for this recipe. I love using a combination of lobster, crab, and shrimp for a rich flavor. If fresh seafood isn’t available, frozen seafood works too—just make sure to thaw it before cooking.
How do I store leftovers?
You can store any leftovers in an airtight container in the fridge for up to 3 days. Make sure they are cooled down before placing them in the container. This keeps your seafood stuffed shells fresh and ready to enjoy later!
Can I freeze seafood stuffed shells?
Yes, you can freeze them! Wrap the assembled dish tightly in plastic wrap, then cover with aluminum foil. It can be stored in the freezer for up to 2 months. When ready to bake, simply thaw it in the fridge overnight before cooking.
My sauce turned out too thin; what can I do?
No worries! If your sauce is too thin, you can thicken it by adding a bit more flour. Create a slurry by mixing 1 tablespoon of flour with a bit of cold water, and then stir it into your sauce while it’s simmering. Cook it for a few minutes until it thickens nicely. Alternatively, adding extra cheese can also help thicken the sauce and enhance that creamy flavor!
Are there any dietary considerations I should be aware of?
Great question! Make sure to ask your guests about allergies, especially related to shellfish or dairy. For a dairy-free option, you can use plant-based cream cheese and nutritional yeast instead of Parmesan. If you want to make the dish gluten-free, look for gluten-free jumbo shells and use cornstarch instead of flour for the sauce.
How do I know when the seafood is fresh?
When selecting seafood, look for clear and shiny shells, a fresh sea scent, and firm texture. For lobster, it should be bright and without dark spots. Avoid any seafood that smells overly fishy or has a dull appearance, which can indicate spoilage. Choosing high-quality seafood will elevate your seafood stuffed shells!
