Seafood Lasagna
Is this for real? Yes, indeed!
Nothing brings more smiles to my family’s faces than when I announce that a lasagna is for dinner. I don’t know what it is but people go crazy for lasagna, or lasagne as it is spelled in the UK, where we live.
I have to admit the seafood lasagna I am sharing today is a step away from the traditional lasagna bolognese. No beef, no tomato sauce in view. Closer, perhaps, to a classic fish pie!
There are three things they do have in common though. The first one is a rich and silky béchamel sauce. It is sometimes called ‘white sauce’. But instead of just finishing the lasagna with it we use it throughout.
Then the cheese! We use fresh mozzarella to top our creamy dish and bake it till golden and bubbly.
Finally, it is that delicious taste and the feeling of bliss right after dinner!

Ingredients
Seafood pasta is quite traditional for Italian cuisine but this lasagna is not. The recipe is NOT authentic Italian but rather inspired by the flavours.
While this seafood lasagna might not be 100% Italian it is 100% delicious, and therefore is worth making!
Just like any lasagna this one consists of lasagna sheets. But instead of meaty red sauce, it is layered with a seafood mix and béchamel sauce.
I used a combination of crab, shrimp, scallops and calamari. However, adding lobster or even chunks of fish like salmon or halibut would make this creamy lasagna even more luxurious.
There is a secret layer hiding in the middle, and it is made of creamy leeks and mushrooms. That layer is so delicious and in my opinion, it’s necessary to break up all that seafood and introduce some veg!

Recipe tips and notes
- Since the seafood doesn’t benefit from a lengthy cooking process, I tried to reduce its time in the oven by using fresh lasagna sheets instead of dried. You can purchase them or make your own. Here is our favourite fresh lasagna sheets recipe.
- Depending on your seafood mix, some may come pre-cooked. In this case, do not cook it again. Simply mix it in with the rest of the seafood when assembling the lasagna.
- If you can’t find fresh pasta sheets, I would recommend pre-cooking your dried lasagna sheets. Just 5 minutes of cooking after the water has boiled would do the trick!
- I used 10 fresh lasagna sheets, 2 sheets per layer to fit into a 9X13 inch pan. However the sizes may vary depending on the product you use. You need enough lasagna sheets for 5 layers.
- Make sure you prepare the béchamel sauce in the same pan where you cooked your seafood, so it will get some seafood flavour from it!
- Also divide the béchamel sauce evenly among the layers and don’t be tempted to increase the amounts. You don’t need to drown the pasta sheets in it. Just a shallow coating will do, otherwise you are risking your lasagna to be too wet and too rich.
- When covering prior to baking, spray the aluminum foil with a cooking spray or brush with oil to avoid sticking to cheese.
- Finally, do not cut into lasagna straight from the oven. Let it settle for good 10 minutes. This way you will have neat stacks!

Serving suggestions
Serve this luxurious lasagna with our Roasted Parmesan Broccoli with Sun-Dried Tomatoes, Garlic and Chilli. A little bit of greens and a touch of spice will bring a nice balance to this creamy dish.
And of course, you’ll want something to soak up any of that delicious sauce from your plate. Air fryer garlic bread or a soft and fresh focaccia will be perfect for the job.
Storage and leftovers
Leftovers can be kept for up to 4 days in a refrigerator. It can be reheated in a microwave or in an oven set to 180C/350F. If you do reheat in an oven, cover with aluminum foil to prevent it from drying out.
Baked lasagna can also be frozen for up to a month. Freeze the lasagna in the baking dish and let it thaw in the fridge before returning to the oven.

Instructions
Prepare the Filling
- Preheat the oven to 180C/350F. Saute minced garlic in butter for 30 seconds over medium heat, then add the seafood mix and a pinch of salt and cook while stirring for 2-3 minutes, add the wine and let it reduce for approximately 5 minutes, stir once in a while. Remove the seafood to a plate and set aside till later.
- To the same pan add the butter and let it melt, then add the flour and mix well, continue cooking the mixture over medium heat while stirring for 2-3 minutes, then add the milk, one bay leaf and ¼ tsp of grated nutmeg, bring to a boil, then let it simmer until the sauce thickens and coats a spoon, season with salt and pepper to taste. (Don't forget to stir to avoid burning!) Set aside till needed.
- In another pan cook the sliced leeks, minced garlic and mushrooms in butter with salt for approximately 7-10 minutes until the leeks are tender and mushrooms are cooked all the way through. Stir in double/heavy cream and 1 tablespoon of chopped parsley. Let the mixture cool slightly.
Assemble the Lasagna
- Cover the bottom of a 9X13 inch (23-33cm) rectangular baking dish with a thin layer of the béchamel sauce. The sauce should just barely cover the bottom, place the fresh lasagna sheets, add half of the seafood mixture and about a third of the remaining sauce.
- Another layer of the fresh (or pre-cooked) lasagna sheets and cover with the leek and mushroom mixture. One more layer of the lasagna sheets followed by the second half of the seafood mix and a third of the béchamel sauce. Finish with the final layer of the lasagna sheets, the rest of the béchamel sauce, then scatter the torn fresh mozzarella cheese all over. Cover with aluminium foil (Tip: spray it with a cooking spray or brush with oil to avoid sticking to cheese) and bake in the preheated oven for 20 minutes. Then uncover and bake for 10-15 minutes until the cheese is bubbly and golden in places. Let the cooked lasagna rest for 10 minutes before cutting it.

Absolutely delicious, but definitely takes longer than 10 minutes to prepare!
Louise says
If I use all fresh fish/seafood (queen scallops are a local delicacy) can I freeze this preferably before cooking?
Julia Frey (Vikalinka) says
Do you mean to freeze the seafood uncooked? I haven’t tried it, so can’t advise but I would not do it for food safety reasons.
Michelle Rose says
Hello, Can the lasagna be frozen before cooking & then thawed and baked. Or would you recommend baking and freezing then reheating?
Julia Frey (Vikalinka) says
Hi Michelle, for better texture I recommend assembling the lasagna, then freezing it without baking. When you are ready to bake, take the lasagna out of the freezer and defrost in the fridge overnight. Take out of the fridge 30 minutes before baking for it to come to room temperature, then proceed with the recipe cooking instruction.
Sam Heath says
The mushrooms and leeks are the key to the fifth star.
Julia Frey (Vikalinka) says
Thanks so much, Sam! Happy you enjoyed it!
Nina says
Can I replace the leek and mushrooms with other vegetables? What do you recommend goes well with the seafood?
Julia Frey (Vikalinka) says
I suppose you can replace them with spinach and zucchini or leave them out.
