| Heavy cream | 1 cup (240 ml) |

Step-by-Step Instructions
Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish with butter or cooking spray.
Prepare the Seafood
Heat the olive oil in a large skillet over medium heat.
Add the diced salmon and half of the shrimp. Cook for approximately 3 to 4 minutes, just until the seafood begins to turn opaque.
Season lightly with salt and black pepper.
Remove from the heat and set aside.
Keep the remaining shrimp raw for the topping.
Make the Alfredo Sauce
Melt the butter in a large saucepan over medium heat.
Add the minced garlic and cook for about 1 minute, until fragrant.
Whisk in the flour and cook for approximately 2 minutes to create a smooth roux.
Gradually pour in the warm milk while whisking constantly.
Add the heavy cream and continue whisking until smooth.
Allow the sauce to gently simmer for approximately 5 to 7 minutes, stirring frequently, until it thickens.
Remove the saucepan from the heat.
Stir in 1 cup of Parmesan until completely melted and smooth.
Season with salt and black pepper to taste.
Prepare the Cheese Filling
In a medium bowl, combine the ricotta, 1 cup of mozzarella, and half of the chopped parsley.
Mix gently until everything is evenly combined.
Assemble the Lasagna
Spread a thin layer of Alfredo sauce across the bottom of the prepared baking dish.
Place 3 to 4 lasagna noodles over the sauce.
Spread a layer of the ricotta mixture over the noodles.
Add a portion of the cooked salmon and shrimp.
Spoon more Alfredo sauce over the seafood.
Continue building the layers until the ingredients are used.
Finish with a final layer of noodles and cover generously with the remaining Alfredo sauce.
Add the Cheese Topping
Sprinkle the remaining mozzarella evenly over the top.
Add the remaining Parmesan.
Arrange the reserved raw shrimp across the surface of the cheese.
Bake
Cover the baking dish loosely with aluminum foil.
Bake at 375°F (190°C) for 30 minutes.
Remove the foil and continue baking for another 15 minutes, or until the cheese is bubbling and beautifully golden and the shrimp are completely cooked.
Rest and Garnish
Remove the lasagna from the oven and allow it to rest for 15 to 20 minutes.
Garnish with the remaining fresh parsley.
Slice carefully and serve warm.
Best Tips
For the smoothest Alfredo sauce, use freshly grated Parmesan instead of pre-shredded cheese.
Pre-shredded cheese often contains anti-caking ingredients that can affect melting and create a less creamy sauce.
Avoid overcooking the seafood during the initial sauté. The salmon and shrimp will continue cooking inside the oven.
Letting the finished lasagna rest before slicing is essential. The creamy sauce needs time to settle so the layers hold together beautifully.
For the best flavor, season each component individually rather than relying only on the final seasoning.
Best Ingredient Options
| Ingredient | Recommended Option |
| Lasagna noodles | High-quality oven-ready or traditional noodles |
| Shrimp | Large fresh or frozen shrimp |
| Salmon | Fresh Atlantic or King salmon |
| Crab | Lump crab meat |
| Milk | Full-fat whole milk |
| Cream | Heavy whipping cream |
| Cheese | Freshly grated Parmesan and whole-milk mozzarella |
| Herbs | Fresh parsley |
Recipe Variations
Shrimp & Lobster Lasagna 🦞
Replace the salmon with cooked lobster meat for an especially luxurious seafood lasagna.
Scallop Seafood Lasagna
Add fresh sea scallops alongside the shrimp for another layer of delicate seafood flavor.
Spicy Seafood Alfredo Lasagna 🌶️
Add ½ teaspoon of crushed red pepper flakes to the garlic and butter while preparing the Alfredo sauce.
For more heat, increase the amount gradually according to your preference.
Spinach Seafood Lasagna 🥬
Add a layer of fresh spinach that has been lightly sautéed and drained.
The spinach adds color and a pleasant vegetable element to the rich creamy layers.
Four-Cheese Version 🧀
Add a small amount of cream cheese or fontina to the cheese mixture for an even richer and creamier result.
What to Serve With
Because this lasagna is rich and creamy, light side dishes make excellent companions.
A crisp arugula salad with lemon vinaigrette provides freshness and acidity that balances the creamy Alfredo sauce.
Crusty garlic bread is another delicious option, especially for soaking up the extra sauce.
Roasted asparagus, green beans, or steamed broccoli can also add freshness and color to the meal.
For a special dinner, serve it with a chilled beverage of your choice for an elegant restaurant-style experience.
Make-Ahead Instructions
The Alfredo sauce can be prepared up to 24 hours in advance.
Store the sauce in an airtight container in the refrigerator.
The seafood mixture can also be prepared ahead and refrigerated separately.
You can assemble the entire lasagna up to 24 hours before baking.
Cover it tightly and refrigerate until ready to bake.
When baking directly from the refrigerator, add approximately 10 to 15 minutes to the covered baking time.
Storage
Allow leftover lasagna to cool before storing.
Transfer individual portions to airtight containers or cover the baking dish tightly.
Refrigerate for up to 3 days.
Because this recipe contains seafood and dairy products, keep it properly refrigerated and avoid leaving it at room temperature for extended periods.
Reheating
Oven Method
Preheat your oven to 350°F (175°C).
Place a portion of lasagna in an oven-safe dish.
Add a small splash of milk or cream to help loosen the sauce.
Cover with aluminum foil and bake for approximately 15 to 20 minutes, or until heated through.
Microwave Method
Place one slice on a microwave-safe plate.
Cover it with a slightly damp paper towel.
Heat at medium power for 2 to 3 minutes, checking halfway through.
Freezing
This lasagna can be frozen for up to approximately 2 months.
For best results, freeze individual portions once completely cooled.
Wrap each portion tightly in plastic wrap, followed by aluminum foil.
Place the wrapped portions in a freezer-safe bag or container.
Thaw overnight in the refrigerator before reheating.
Cream-based sauces may experience a slight texture change after freezing and thawing, but the lasagna will still be delicious.
Common Mistakes to Avoid
Overcooking the seafood: Shrimp and salmon cook quickly. Keep the initial cooking brief because they will continue cooking during baking.
Making the sauce too thin: Allow the Alfredo sauce to thicken properly before assembling the lasagna.
Skipping seasoning: Season the seafood, cheese mixture, and Alfredo sauce separately for a more flavorful final dish.
Overcooking the noodles: If using traditional noodles, cook them only until al dente. They will continue absorbing moisture during baking.
Cutting too soon: Allow the lasagna to rest for at least 15 minutes before slicing so the layers can set.
Using cold ingredients: Warm milk helps create a smoother Alfredo sauce and reduces the chance of lumps.
