Seafood Lasagna with Spinach

January 20, 2026

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 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, this lasagna 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.

    My kids loved it, but not sure I wanna tell them it’s seafood. They think all pasta should be cheese or meat. LOL!

    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!

  14. 1 star
    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! 🤔

    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!

    1. 3 stars
      Glad he liked it! But… seafood in lasagna? I dunno, seems a bit weird to me. Does it really taste good?

    Um, I didn’t have all the ingredients, so I just used whatever was in the pantry… it still turned out ok, but not as good.

    Was super confused about the herbs. Can I just throw in whatever? It needs a instruction for dummies.

    1. User avatar jess.trantow36 says:

      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.

      Seafood in lasagna? Really? That’s kinda weird. I prefer it the classic way. But if you say it’s good, maybe I’ll try it! 🤔

    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…

    1. User avatar leoma.mcdermott says:

      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!

    1. User avatar leilani.kuhic19 says:

      I dunno about all that. Spinach in lasagna? Seems weird to me. I prefer the classic.

    I thought lasagna was supposed to be beefy! WHY seafood? Seems weird but I tried it for my seafood-loving friend.

  35. User avatar Chi Shenlong says:

    It looked fancy but took way too long to make. I got frustrated halfway. Maybe I’m just not cut out for this.

    1. 4 stars
      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!

  36. 1 star
    No way this is good, seafood with pasta? Yuck. I’ll stick to the classic meat one.

    Tried this without the shrimp (allergic) and it still came out good! Used extra crab and some spinach.

  39. 4 stars
    I tried making this but ended up forgetting the thyme. It tasted fine, but I think it would be even better with all the spices.

  40. 4 stars
    Delicious! Who knew seafood could be a lasagna filling? I used crab sticks instead of crabmeat and it still tasted great!

    Fish in lasagna sounds gross! Not sure why anyone would wanna eat that.

    1. User avatar elaine.huels says:

      Eww! Fish and lasagna don’t go together! Stick to meat or veggies, that’s real lasagna.

    2. User avatar Jenee Bashirian says:

      I actually think it sounds unique! Seafood brings a different flavor to lasagna, and I love shrimp. Can’t wait to try it!

    The recipe was okay, but it felt like too much cheese. Like, maybe cut back a bit next time? Too rich.

  49. 5 stars
    This lasagna is to die for! I never thought seafood could work in lasagna, but it’s amazing!

    Not sure if I did it right. My noodles were a bit mushy and the sauce seemed more like a soup. Could use better instructions!

    1. 4 stars
      Sounds like you may have overcooked the noodles! Follow the times indicated and maybe let the sauce simmer a bit longer to thicken. But hey, it still probably tasted good!

    2. User avatar shakita.mohr says:

      3 stars
      I had the same issue! My noodles turned out mushy too. Maybe try cooking them for a shorter time? The sauce was pretty soupy for me as well. I think I may have messed it up somehow.

    BEST SEAFOOD LASAGNA EVER!!! Totally impressed my family, and now they want it every week 🙂

  52. 1 star
    This was a disaster in my kitchen… I burned the sauce and my cheese didn’t melt well. Ugh.

  53. 3 stars
    Did anyone else have trouble with the noodles sticking together? I think maybe I did something wrong.

  54. 2 stars
    I’m skeptical about mixing seafood and pasta. Just sounds weird to me. Has anyone tried changing it up with chicken?

    1. User avatar erick.beahan says:

      2 stars
      Seafood lasagna? That sounds gross! Chicken would probably be better but pasta and seafood is like mixing oil and water, just… no.

    2. User avatar ray.gulgowski1968 says:

      4 stars
      I totally get your skepticism! Mixing seafood with pasta can be a bit of a reach for some. I’ve tried with chicken, and honestly, it’s a game changer! You should give it a shot!

  55. 4 stars
    So good! The shrimp and crab were just perfect together! Overall a great dish for special occasions.
