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?

  13. 5 stars
    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! 🤔
