This creamy Seafood Lasagna is the ultimate comfort meal for anyone who loves the flavors of the ocean mingling with rich Italian tradition. I reach for this recipe when I want something impressive but still fairly quick on a weeknight or when the family gathers to share something a bit special. With silky béchamel and pockets of ricotta, each bite delivers a gentle richness that lets shrimp, scallops, or whatever seafood you fancy truly shine.
The first time I made this, my youngest picked out all the shrimp—now she claims the memorable crunchy edge portions for herself. It has turned into our celebration meal every summer when the fish markets are at their best.
Ingredients
- Butter: decides the richness of your béchamel so reach for real unsalted if you can
- All purpose flour: is essential for thickening
- Whole milk: gives the sauce a luxurious mouthfeel and smoothness
- Freshly grated parmesan: adds savory depth and nuttiness—select a wedge and grate just before using for best flavor
- Ricotta cheese: lends creaminess and blends easily plus good quality brands have fewer stabilizers
- Mozzarella: makes for that classic cheese pull so find low moisture blocks to shred yourself
- Egg: binds your cheese layer for a custard like texture
- Dried parsley: brightens and balances the richness—rub between your fingers to release extra aroma
- Seafood mix: is the star shrimp scallops or flaky white fish all work well just choose what looks plump and fresh
- Olive oil: helps sauté the seafood without overpowering its flavor use extra virgin for more fragrance
- Lasagna noodles: bring everything together choose fresh if available for pillowy layers or dried for a bit more bite
- Salt and pepper: are for seasoning each layer so do not skimp or forget a light touch brings out all the other nuances
Instructions
- Preheat the Oven:
- Set your oven to one hundred eighty Celsius or three hundred fifty Fahrenheit. Prepare your baking dish by greasing with butter or a non stick spray. A good even coat helps each piece serve up easily later.
- Make the Béchamel Sauce:
- Melt butter in a saucepan over medium heat until foamy. Sprinkle in flour and whisk vigorously for about a minute until fragrant and just golden—this step eliminates raw flour taste. Pour in milk gradually whisking without pause until the mixture thickens. Stir in parmesan until the cheese is melted and the sauce is silky. Remove from heat and set aside but cover to keep warm.
- Prepare the Cheese Mixture:
- In a medium mixing bowl combine the ricotta mozzarella whisked egg dried parsley and salt. Mix everything with a spoon until smooth and uniform. The mixture should be spreadable so add a splash of milk if too thick.
- Sauté the Seafood:
- Heat olive oil in a large skillet until shimmering but not smoking. Add your seafood mix sprinkle in salt pepper and parsley. Sauté for about three minutes stirring gently until the seafood turns opaque and just barely cooked through. Avoid overcooking as residual heat finishes the job in the oven.
- Layer the Lasagna:
- Spoon a generous layer of béchamel sauce into the base of your prepared baking dish and spread all the way to the edges. Place lasagna noodles in an even layer over the sauce. Dollop and gently spread a third of the cheese mixture over the noodles. Scatter a third of the seafood over the cheese and top with a third of the béchamel. Repeat for two more layers finishing with béchamel and a handful of shredded mozzarella on top for a golden cheesy crust.
- Bake to Perfection:
- Transfer the dish to your preheated oven and bake for about thirty five minutes. Check the top after twenty five minutes. If it is browning quickly tent loosely with foil and return to the oven until bubbling and the noodles are tender.
- Rest and Serve:
- When baking is done let the dish sit on a rack for at least ten minutes before slicing. This pause makes the lasagna easier to serve in neat squares without losing any of the creamy filling.

What I love most is how the ricotta holds everything together without overpowering the seafood. I still remember the first time I pulled this from the oven for a Sunday lunch and everyone paused for a second before digging in—the whole house smelled like an Italian coastal kitchen.
Storage Tips
Store leftovers in an airtight container. Keep in the fridge for up to three days for the best flavor and texture. For freezing, cool the lasagna completely then wrap tightly in a double layer of plastic or foil. Freeze for up to two months for easy make ahead meals.
Ingredient Substitutions
If you are out of ricotta cottage cheese makes a fine substitute. For the seafood mix shrimp scallops crab or cod all work. You could even use pre cooked lobster if you have leftovers from a special dinner. Dried lasagna sheets work if you boil them just until pliable.
Serving Suggestions
This lasagna needs little more than a crisp green salad with lemon vinaigrette or a dish of sautéed greens. Cheesy garlic bread is never wrong and for a bit of sparkle serve with cold sparkling water or a crisp sauvignon blanc.
Cultural Inspiration
Seafood lasagna is not traditional in Italy but Italian American kitchens have turned it into a classic for Christmas Eve and Lent. Inspired by the flavors of the Mediterranean coast this version adds a touch of luxury to family meals with ingredients that would have felt celebratory at any seaside table.
Seasonal Adaptations
Use fresh basil or dill in summer to add brightness. In winter try adding a handful of baby spinach for color and nutrition. Substitute local seafood like clams or mussels if those are available where you live.
Success Stories
So many readers have told me they built their confidence with this recipe and now make it for every anniversary or big family dinner. Once you master the layering it becomes second nature and every batch comes out better than the last.
Freezer Meal Conversion
Let the lasagna cool completely before wrapping for the freezer. Slice before reheating individual portions so each piece warms evenly. If serving a crowd from frozen let the whole dish thaw overnight in the fridge and reheat covered until bubbling throughout.

Take your time with layering and let the finished lasagna rest before serving. These two simple steps ensure every cheesy slice comes out picture perfect and delicious.
