- Butter: 4 tablespoons unsalted butter for the luscious roux base of the sauce.
- All-purpose flour: 1/4 cup used to thicken the sauce into a creamy consistency.
- Whole milk: 4 cups added slowly to create a silky cheese sauce.
- Garlic powder: 1 teaspoon infuses a gentle savory note throughout the sauce.

How to Make Seafood Lasagna with Shrimp, Crab, and Creamy Cheese Sauce Recipe
Step 1: Prepare the Oven and Roux
Start by preheating your oven to 375°F (190°C). In a medium saucepan, melt the unsalted butter over medium heat. Once melted, whisk in the all-purpose flour, cooking for about 2 minutes until the mixture turns a lovely golden color. This roux is the essential base for a creamy, smooth cheese sauce that will bind the entire lasagna together with silkiness.
Step 2: Make the Creamy Cheese Sauce
Slowly pour the milk into the roux while whisking continuously to prevent lumps. Continue stirring for 5 to 7 minutes until the sauce thickens to a luscious, velvety consistency. Now, season with garlic powder, onion powder, salt, and pepper to build layers of flavor that marry beautifully with the seafood. Remove the sauce from heat and stir in freshly chopped parsley for a subtle herbaceous kick.
Step 3: Layer the Ingredients
Grab your baking dish and spread a thin layer of the creamy sauce at the bottom to prevent sticking and add moisture. Layer three lasagna noodles evenly on top, then spread half of the ricotta cheese over them. Evenly distribute half of the shrimp and crab, then sprinkle a third of the shredded mozzarella cheese. Each layer adds richness, texture, and flavor, so take your time to build those tasty strata.
Step 4: Repeat and Finish the Top
Repeat the layering process with another three noodles, the remaining ricotta, the rest of the seafood, and another third of the mozzarella. Finish with a final layer of noodles, spread the remaining creamy sauce on top, and cover generously with the rest of the mozzarella and all of the Parmesan cheese. This final cheese layer will create a golden, bubbly crust that’s pure perfection.
Step 5: Bake to Perfection
Cover the dish with foil and bake for 25 minutes to let all the layers meld and cook through. Then remove the foil and bake uncovered for an additional 15 minutes. This step allows the cheese on top to brown beautifully and become wonderfully bubbly, signalling that your seafood lasagna is ready to come out of the oven.
Step 6: Rest and Serve
Let the lasagna cool for about 10 minutes before slicing and serving. This resting time helps the layers set so every piece stays intact and looks as stunning on the plate as it tastes.
How to Serve Seafood Lasagna with Shrimp, Crab, and Creamy Cheese Sauce Recipe
Garnishes
A sprinkle of fresh parsley or a few thin lemon zest strands on top bring brightness and fresh aroma, balancing the richness. A light drizzle of good-quality olive oil can add extra silky richness on the plate if desired.
Side Dishes
This hearty lasagna pairs perfectly with crisp, refreshing sides like a simple mixed green salad with lemon vinaigrette or roasted vegetables to provide a pleasant contrast of textures and flavors. Garlic bread or a crusty baguette is also perfect for mopping up any extra creamy sauce.
Creative Ways to Present
Elevate your presentation by serving individual portions in small ramekins or cast iron skillets straight from the oven for a rustic touch. Layer a few extra whole shrimp or crab claws on top as a decorative nod to the seafood inside, creating a show-stopping centerpiece for any dinner gathering.
Make Ahead and Storage
Storing Leftovers
Store any leftover seafood lasagna in an airtight container in the refrigerator. It will keep well for up to 3 days, making it a fantastic option for easy weekday lunches or dinners that feel indulgent yet convenient.
Freezing
This dish freezes beautifully. Wrap the entire lasagna or individual portions tightly in plastic wrap and foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating
To reheat, cover the lasagna with foil to prevent drying out and warm it in a 350°F (175°C) oven for about 20-25 minutes, or until heated through. You can also microwave individual slices, but the oven ensures the best texture and flavor preservation.
FAQs
Can I use other types of seafood instead of shrimp and crab?
Absolutely! This recipe is very flexible. You can swap in scallops, lobster, or even chunks of firm white fish. Just make sure to adjust cooking times for any seafood that cooks faster or slower to avoid overcooking.
Is it possible to make this seafood lasagna gluten-free?
Yes! Use gluten-free lasagna noodles and substitute the all-purpose flour with a gluten-free flour blend or cornstarch for the roux. The rest of the ingredients are naturally gluten free, so it’s easy to adapt.
Can I prepare the sauce in advance?
Definitely. The creamy cheese sauce can be made a day ahead and refrigerated. When ready to assemble, gently warm it on the stove to soften before layering to make the process even faster.
What cheese can I substitute if I don’t have ricotta?
Cottage cheese is a great alternative to ricotta and provides a similar texture with a slightly different flavor. You can also blend cottage cheese with a bit of cream cheese for extra creaminess.
How do I ensure the seafood stays tender and doesn’t get rubbery?
Using pre-cooked shrimp and fresh lump crab meat helps, as these cook quickly and gently when baked with the sauce. Avoid overbaking by following the recipe’s time carefully and letting the lasagna rest before serving.
