This seafood lasagna transforms everyday comfort food by swapping traditional ground meat for a yummy seafood blend. The mix of velvety béchamel, luscious cheese, and juicy seafood makes a standout meal that's fancy enough for special occasions but easy enough for regular dinners.
I came up with this seafood lasagna when some friends who enjoy Italian food popped by for dinner unexpectedly. They wanted something different from the usual fare. The seafood-pasta combo was such a success that it's now my favorite showstopper when I need to whip up something special without spending forever cooking.
- Butter: Creates the foundation for our béchamel sauce adding richness and helping make that smooth texture
- All-purpose flour: Teams up with butter to make the sauce thick and lump-free
- Milk: Forms the béchamel's creamy base; go for whole milk for the tastiest outcome
- Parmesan cheese: Gives a salty, nutty kick that makes the seafood taste even better; grab freshly grated for smooth melting
- Ricotta cheese: Adds a soft, creamy layer with mild flavor; pick whole milk ricotta for extra goodness
- Mozzarella cheese: Makes those awesome stretchy cheese strings; go for low moisture type for better melting
- Egg: Holds the cheese filling together and boosts richness
- Dried parsley: Brings color and gentle herb flavor that works well with seafood
- Seafood mix: Saves time and adds variety; try to get one with shrimp, squid, and mussels
- Fresh lasagna noodles: They cook quicker and feel better in your mouth than dried ones; no need to boil first
- Olive oil: Browns the seafood and builds flavor; extra virgin tastes best
Easy Seafood Lasagna Steps
- Fix The Béchamel:
- Heat butter in a pot over medium until it bubbles without browning. Toss in flour and stir non-stop for just one minute to get rid of that raw flour taste. Pour milk in slowly while whisking all the time so no lumps form. Keep stirring for about 5 minutes until sauce gets thick enough to coat a spoon. Mix in parmesan until it melts completely then take off the heat.
- Mix The Cheese Stuff:
- Put ricotta, mozzarella, egg, dried parsley, and salt in a bowl. Stir everything together until it's all mixed up and smooth. This makes a creamy part that balances out the seafood really well.
- Fix The Seafood:
- Warm up olive oil in a pan over medium-high heat until it looks shiny. Put in the seafood mix making sure pieces aren't stacked up so they cook evenly. Add some salt, pepper, and parsley then cook for exactly 3 minutes, just until the outside starts to change color but isn't fully cooked. The seafood will finish cooking in the oven so it stays tender.
- Stack Everything Up:
- Spread a thin layer of béchamel on the bottom of your greased dish making sure you cover the whole surface. Put down lasagna sheets so they slightly overlap if needed. Spread a third of your ricotta mix evenly on the pasta then add a third of the seafood, spreading it out nicely. Pour a third of the remaining béchamel over this. Do this layering thing two more times, ending with mozzarella and a sprinkle of parmesan on top.
- Bake It Just Right:
- Put your lasagna in the preheated oven and bake for 35 minutes until the top turns golden and starts bubbling. If the top gets too brown too fast, cover it loosely with foil after about 20 minutes. Let it sit for 10 minutes before cutting so the layers can set and you get neater slices.

The seafood mix really makes this dish special. I learned this trick while visiting the Italian coast where local fishermen brought fresh catch to family restaurants daily. A sweet old grandma showed me that quickly cooking the seafood before putting the lasagna together keeps its soft texture and flavor better than any other way I'd tried.
Picking The Best Seafood
When you're shopping for seafood for this lasagna, quality really matters. Try to visit a fish shop or seafood counter instead of grabbing frozen stuff if you can. Fresh seafood just tastes better and has nicer texture. Look for a mix with firm white fish, shrimp, and scallops to get different textures in each bite. Make sure all pieces are about the same size so they cook evenly. If you do use frozen seafood, thaw it all the way and pat it dry with paper towels before cooking or your lasagna might turn out watery.
Prep It Early
This seafood lasagna works great for busy folks because you can get it ready ahead of time. You can put the whole thing together up to a day before you plan to bake it and keep it covered in the fridge. When you're ready to eat, just add about 10 extra minutes to the cooking time since it'll be cold from the fridge. You can also freeze the uncooked lasagna for up to 3 months if you want. Just wrap it up tight in plastic wrap and then aluminum foil so it doesn't get freezer burn. Thaw it in the fridge overnight before cooking and add about 15 more minutes to the baking time.

Tasty Wine Matches
This seafood lasagna goes really well with certain wines that work with its delicate flavors instead of overwhelming them. A crisp Chardonnay that hasn't been aged in oak barrels is great with the creamy sauce and seafood. The buttery taste in the wine makes the rich béchamel even better while the tartness cuts through the cheese. You could also try Pinot Grigio from northern Italy which has bright tartness and subtle mineral notes that make the seafood taste even better. If you prefer red wine, a light Pinot Noir can work pretty well especially if your seafood mix has stronger flavors like squid or mussels. Serve the wine a bit cool to enjoy it more with this special dish.
