Seafood Lasagna with Spinach is a luxurious and hearty variation of the traditional lasagna, featuring a rich combination of seafood, creamy béchamel sauce, and fresh spinach layered between sheets of pasta. This indulgent dish is perfect for special occasions or whenever you want to elevate your usual lasagna recipe with the delicate flavors of shrimp, scallops, or other seafood, balanced by the freshness of spinach and the creaminess of the sauce.
The base of this lasagna is a creamy béchamel sauce made with butter, flour, milk, and a touch of nutmeg. The béchamel adds a silky, velvety texture that perfectly binds the layers together. For added richness, Parmesan cheese is mixed into the sauce, providing a sharp contrast to the sweetness of the seafood.
The seafood filling, made from a mix of shrimp, scallops, and other shellfish, is sautéed until just cooked, ensuring it stays tender and flavorful. The seafood is then combined with spinach, which adds a fresh, slightly earthy flavor that complements the delicate sweetness of the seafood. The spinach is wilted, allowing it to blend seamlessly into the dish without releasing excess moisture.
The layers of lasagna are built by alternating sheets of pasta, the seafood and spinach mixture, and the creamy béchamel sauce, creating a comforting, indulgent dish that’s rich in flavor but not overly heavy. The lasagna is topped with a blend of mozzarella and Parmesan cheeses, which melt beautifully into a golden, bubbly crust as the dish bakes.
Once baked, the lasagna is a masterpiece of layers: the pasta is tender and slightly chewy, the seafood and spinach mixture is flavorful and succulent, and the sauce binds it all together in a rich, creamy embrace. A sprinkle of fresh herbs, such as parsley or basil, on top adds a bright, fragrant finish.
Seafood Lasagna with Spinach is perfect for anyone who loves seafood and wants to try something different with their lasagna. It’s a perfect dish for a dinner party, holiday gathering, or a cozy family meal that feels special yet comforting.
In summary, Seafood Lasagna with Spinach takes the classic lasagna and elevates it with the delicate flavors of seafood and the freshness of spinach, all wrapped in a creamy béchamel sauce. It’s a rich, indulgent dish that’s perfect for any occasion, offering a flavorful and luxurious twist on a traditional favorite.

Isn’t lasagna supposed to have ground meat? This recipe is weird. 1 star for that.
This is the best lasagna I’ve ever made! The seafood combo is just delicious. Five stars!
I was skeptical about seafood in lasagna, but this turned out surprisingly good! I was worried the flavors would clash, but they didn’t. Will make again! 😊
My kids loved it, but not sure I wanna tell them it’s seafood. They think all pasta should be cheese or meat. LOL!
Absolutely delicious! This seafood lasagna is a hit at our dinner parties. So cheesy and packed with flavor! 😍
Seafood and dairy? Sounds like a recipe for disaster to me. Not gonna risk it.
Took longer than I thought. But it turned out yummy! Will make again, just have to be prepared.
Looks fancy but actually quite easy! Highly recommend!
I can’t even pronounce half of these spices! Do I really need tarragon? Anyway, I’ll try it without.
You don’t really need tarragon! I leave it out too, it still tastes great! Good luck!
Do I really need to boil the noodles? Can’t I just layer them dry?
YOU GUYS!!! This is like heaven on a plate! So rich and creamy! I added more garlic. YUM!
Yuck! My family didn’t like this at all. The fish tasted off. Maybe fresh seafood would be better? 1 star for effort.
I totally get you! My first try was a flop too. Maybe next time fresh seafood will help! 🤔
This lasagna was a hit at our family dinner! So creamy and delicious!
So easy to make! I added some scallops for an extra kick.
The sauce was a bit too salty for me. Maybe less salt next time?
Yeah, I found it salty too! I used less salt and it turned out great.
This recipe is a seafood lover’s dream! My family devoured it!
Looks tasty, but I have my doubts about seafood in lasagna. Just sounds weird to me.
I’m so glad to hear your family loved it! Seafood lasagna is one of my favorites too!
Love this dish! Made it last weekend and everyone loved it! Spinach adds a nice touch. 👍🏻
OMG! I can’t believe how good this is! I was skeptical about seafood in lasagna but this changed my mind! <3
I had the same reaction! Seafood lasagna is surprisingly amazing! I usually stick to meat but this is a game changer! 🔥
Lasagna no strong, put in on plate should taste good
Hmm, not sure about shrimp and crab in lasagna. Sounds strange. I think I’ll stick to the traditional meat version.
Yum! My husband can be picky but he loved it. Will make again!
Glad he liked it! But… seafood in lasagna? I dunno, seems a bit weird to me. Does it really taste good?
That’s awesome! It’s always nice when a picky eater enjoys something. What did you serve it with?
Was super confused about the herbs. Can I just throw in whatever? It needs a instruction for dummies.
Instructions for dummies? Come on, it’s not that hard. Just follow the steps! 🤷♂️
I feel you! Just pick some herbs you like, it’ll probably still taste good. 👌
Eh, it was okay. A bit too fishy for my taste. Might skip the seafood next time.
Made this for my family and they loved it! Super easy to follow and full of flavor.
I don’t see how this could be good. Lasagna is for meat, not shrimp and crab. Sounds weird to me. 🤔
I don’t know, sounds kinda weird to put seafood in lasagna…
I agree! Seafood in lasagna is very unusual. I would much rather stick to the classic meat version.
Love the spinach! Great way to get my greens in. Also, cheese is life!
Totally agree! Spinach and cheese make everything better. Can’t wait to make this!
I dunno about all that. Spinach in lasagna? Seems weird to me. I prefer the classic.
I ain’t got time for all these layers and stuff. Threw everything in a pot, and it was fine!
A little too spicy for me, but I can see how others might love it. Not my fave.
I thought lasagna was supposed to be beefy! WHY seafood? Seems weird but I tried it for my seafood-loving friend.
It looked fancy but took way too long to make. I got frustrated halfway. Maybe I’m just not cut out for this.
I get it! Some recipes are way too complicated. Maybe try simpler ones until you feel more confident? Cooking should be fun, not a headache!
