Creamy Seafood Stuffed Shells Ingredients
For the Pasta
• Jumbo Pasta Shells – The ideal shape to hold your rich seafood filling; you can use cannelloni or manicotti as substitutes.
For the Filling
• Lobster Meat (8 oz) – Elevates the dish with its sweet, luxurious flavor; fresh or high-quality frozen works best.
• Crab Meat (8 oz) – Provides a tender texture and pairs beautifully with other seafood; use fresh for the best taste.
• Shrimp (8 oz) – Adds a firm, succulent bite; scallops or white fish can substitute if desired.
• Cream Cheese (4 oz) – Brings a velvety creaminess to the filling; light cream cheese is a great alternative for a healthier option.
• Mozzarella Cheese (1 cup, freshly shredded) – Adds gooey meltiness; steer clear of pre-shredded for optimal results.
• Garlic (2 cloves, minced) – Enriches the dish with aromatic depth; feel free to add more for extra flavor.
• Salt (1 tsp) – Brightens all the flavors; adjust according to taste preferences.
• Pepper (1 tsp) – Lends just a hint of spice; use white pepper for a milder heat.
For the Sauce
• Butter (4 tbsp) – The base for your luscious sauce, can be swapped with olive oil for a lighter twist.
• Flour (2 tbsp) – Thickens the sauce to creamy perfection; use gluten-free flour for a gluten-sensitive option.
• Heavy Cream (1 cup) – Makes the sauce luscious and decadent; substitute with half-and-half for a lighter take.
• Parmesan Cheese (½ cup) – Adds a savory, salty kick; nutritional yeast can replace it for a vegan option.

Step‑by‑Step Instructions for Creamy Seafood Stuffed Shells
Step 1: Prepare Seafood
In a skillet, melt 2 tablespoons of butter over medium heat, then add minced garlic and sauté for about 1 minute until fragrant. Next, add the lobster and crab meat and cook for 2-3 minutes until warmed through, stirring gently to avoid breaking the seafood. Once cooked, transfer the seafood mixture to a bowl and set aside while you prepare the filling.
Step 2: Mix Filling
In the same bowl, combine the cooked seafood mixture with cream cheese and half of the shredded mozzarella. Season with salt and pepper, then use a fork or spatula to blend everything together until smooth and creamy. This rich filling will be the star of your Creamy Seafood Stuffed Shells, so ensure it’s well combined and deliciously seasoned.
Step 3: Cook Pasta
Bring a large pot of salted water to a boil and carefully add the jumbo pasta shells. Cook for approximately 8-10 minutes until al dente, stirring occasionally to prevent sticking. Once cooked, drain the shells and allow them to cool slightly for easier handling as you prepare to stuff them with the luxurious seafood filling.
Step 4: Make Sauce
In the skillet, melt the remaining 2 tablespoons of butter over medium heat, then whisk in the flour to form a roux, cooking for about 1-2 minutes until bubbly. Gradually stir in the heavy cream, followed by the remaining mozzarella and parmesan cheese until the sauce is creamy and smooth. This sauce will coat your stuffed shells beautifully.
Step 5: Assemble
Preheat your oven to 375°F (190°C). In a baking dish, spread a layer of the creamy sauce across the bottom to prevent sticking. Carefully fill each pasta shell with the seafood mixture and place them in the dish. Once all shells are filled, pour the remaining sauce generously over the top, ensuring to cover each shell.
Step 6: Bake
Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. This allows the flavors to meld and the shells to heat through. After 20 minutes, remove the foil and bake for an additional 10 minutes, or until the top is bubbly and golden brown, enticingly beckoning you to enjoy!
Step 7: Serve
Once baked to perfection, let the Creamy Seafood Stuffed Shells cool for a few minutes. Garnish with extra parmesan or fresh herbs if desired, and serve warm for a delightful dining experience. Each bite is a mouthwatering blend of tender pasta and rich seafood that’s sure to impress your family and friends.

Expert Tips for Creamy Seafood Stuffed Shells
-
Gentle Handling: Be careful when handling pasta shells; they are delicate and can break if mishandled. Cook them al dente for easier stuffing.
-
Fresh Ingredients Only: Choose fresh seafood for the best flavor. Fresh lobster, crab, and shrimp elevate your Creamy Seafood Stuffed Shells to a whole new level.
-
Avoid Pre-Shredded Cheese: For optimal melting and texture, always use freshly shredded mozzarella. Pre-shredded varieties contain anti-caking agents that ruin your creamy sauce.

Make Ahead: Preparing the Creamy Seafood Stuffed Shells a day in advance allows flavors to meld wonderfully. Simply cover and refrigerate, then bake when ready!
-
Baking Tip: Keep the foil on for the first half of baking to lock in moisture, then uncover to achieve that gorgeous golden top.
How to Store and Freeze Creamy Seafood Stuffed Shells
Fridge: Store leftover Creamy Seafood Stuffed Shells in an airtight container for up to 3 days to maintain freshness.
Freezer: For longer storage, wrap the stuffed shells tightly in plastic wrap and aluminum foil. They can be frozen for up to 3 months.
Reheating: To reheat, thaw overnight in the fridge, then bake covered at 350°F (175°C) for about 20 minutes, removing the cover for the last few minutes to restore crispiness.
