This creamy seafood lasagna is hearty and cozy comfort food with a sophisticated twist! Layers of noodles and a succulent seafood mixture bake together in a creamy béchamel sauce. Similar to our lasagna with cottage cheese, this meal is perfect for large family gatherings or even a special occasion. With a rich white sauce and tender chunks of seafood in every bite, this elevated lasagna might just become a new family favorite.

This seafood lasagna is pasta baked in a creamy béchamel sauce with a selection of shellfish, fish, fresh herbs and seasoning. It is layered with lasagna noodles, baked in a casserole dish, and topped off with a healthy grating of mozzarella cheese. 

The Italian name for this dish is “Pasticcio di Pesce” which, translated, is “pasta baked in a creamy seafood sauce.” It is everything you love about lasagna except in seafood form. 

The white bechamel sauce is thick, creamy, rich, and ultra-satisfying. It’s the perfect sauce for seafood because it lets all the flavors shine.

About Our Seafood Lasagna Recipe

This recipe is an adaptation from a wonderful Italian restaurant in Vancouver, BC, called Umberto’s. It’s no longer open, but it was one of our favorite restaurants, and we have been known to go to Vancouver for the sole purpose of having a special dinner there.

The seafood lasagna was delightful and it inspired us to create our own version. It does not disappoint! Our Grilled Rack of Lamb is another adaptation of a dish we enjoyed there. 

Why This Recipe Works

Our white seafood lasagna features a mix of shrimp, scallops, salmon and cod, but the great thing about this easy seafood recipe is you can swap in your favorite types of seafood if there’s one in particular you don’t care for (or have on hand). We’re sharing substitution ideas below. 

This creamy seafood lasagna recipe is:

  • a delicious twist on two of our favorite pasta recipes- classic lasagna meets seafood pasta!
  • rich, creamy and savory, and the flavor of the seafood medley is not lost or overpowered
  • an elevated dish fit for any special gathering.

The Ingredients

This seafood lasagna is from the northern region of Italy, and I’ve adapted it just a little bit by my selection of seafood and the addition of cheese.

The “authentic” recipe, according to Mr. Umberto, does not include cheese because it is believed the cheese can detract from the intense seafood flavors. 

However, we like this dish with a bit of mozzarella cheese since it’s very mild and helps to bind the dish together, similar to a classic lasagna.

Mr. Umberto also explained that “pasticcio” means “trouble” because when the lasagna is cut and transferred to a plate, it loses its shape and becomes messy. You can omit the cheese if you like, but know that the lasagna will be a bit looser and “messy” without the mozzarella. 

Here are the ingredients you will need for this tasty seafood lasagna:

  • Lasagna noodles. What’s a lasagna without those classic, wide noodles layered in between all that deliciousness? You can use oven-ready lasagna noodles, regular noodles, or make your own einkorn pasta.
  • Spices and seasonings. Salt, grated nutmeg and white or black pepper. If you don’t have fresh grated nutmeg, ground nutmeg is okay too.
  • Whole milk. For the béchamel sauce. Whole milk will make the sauce extra rich and creamy. 
  • Butter. A staple in creating the perfect béchamel sauce!
  • All-purpose flour. You will need just a little bit for the creamy sauce. 
  • Garlic cloves. Minced garlic will give the seafood lasagna a light, savory flavor.
  • Sliced mushrooms. The savory, umami flavor of mushrooms adds a touch of earthiness to this seafood filling. 
  • Seafood. We use a mix of shrimp, scallops, cod and salmon (reserve any juices). 
  • Shredded mozzarella cheese. Mozzarella gives it the perfect amount of cheesiness without overpowering the other ingredients.

How to Make Seafood Lasagna

Lasagna involves several components and is a labor of love, but it is worth all the time. Here is a breakdown of the steps to make this seafood delicacy.

Make sure to scroll all the way down to the printable recipe card for detailed instructions.

Making bechamel sauce in a large saucepan.

Make the béchamel sauce. Melt the butter over medium heat and add the flour. Cook, stirring, until the flour is mixed in well, then whisk in the hot milk. Cook the mixture until it thickens. Stir in the nutmeg, salt, and pepper.

Sautéing mushrooms in a saucepan.

Heat oil in a large skillet over medium-high heat. Cook the mushrooms until the water evaporates.

Adding the seafood to a hot saucepan.

Add the seafood and cook just until the shrimp begins to turn pink. 

Mixing the white sauce into the cooked seafood.

Add the sauce to the mixture and broil to a boil, gently mixing the sauce with the seafood. Remove from heat and stir in lemon juice. 

Adding a layer of lasagna noodles in a dish.

Assemble the lasagna by starting with a thin layer of the sauce and adding a layer of lasagna noodles.

Layering the seafood and sauce mixture in the lasagna.

Spread a layer of the seafood and sauce over the noodles.

Adding a layer of shredded cheese to the lasagna.

Top the seafood with a layer of cheese, then repeat all the layers.

Tips for Success

  • Lasagna noodles: Store-bought lasagna noodles is what we use, but this recipe will work with other options tooIf you want to use no-boil lasagna noodles then that will work with this recipe as well. Just add 1/4 cup water to the white sauce and make sure you completely cover the noodles with the sauce.I prefer the kind that you have to boil because it holds up better to the chunky layers in this lasagna.
  • You can make this ahead of time. Simply prepare all the components, build the layers, then cover it and keep it in the fridge for up to 2 days until you are ready to bake it.
  • Thin the sauce if needed: If the white sauce gets too thick, add a little milk or chicken broth and stir until it reaches the desired consistency.
  • For a shortcut: If you don’t want to take the time to make your own bechamel sauce, then purchase a jar of Alfredo sauce.

Storing Seafood Lasagna

The leftovers keep well in the refrigerator for 4-5 days. You can also freeze seafood lasagna, too! Make sure to let it cool completely then store it in a freezer-proof container for up to 6 months.

To Freeze

Freezing lasagna is a great way to have a delicious meal on hand for busy days or when you don’t feel like cooking. Here are the steps to freeze lasagna:

  1. Let the lasagna cool completely before freezing. 
  2. Cover it tightly with plastic wrap then wrap it in aluminum foil. Make sure there are no gaps in the wrap, as this will help prevent freezer burn.
  3. Freeze for up to 3 months.

To Reheat Frozen lasagna:

  1. Preheat your oven to 375°F (190°C).
  2. Let the lasagna thaw overnight in the refrigerator.
  3. Remove the plastic wrap and the aluminum foil.
  4. Cover with foil and bake for about 45 minutes, or until heated through.

  • 9 to 12 lasagna noodles
  • 1 tablespoon kosher salt

For the béchamel sauce:

  • 3 cups whole milk
  • 5 tablespoons butter
  • 6 tablespoons all-purpose flour
  • ¼ teaspoon fresh grated nutmeg
  • ½ teaspoon sea salt
  • ¼ teaspoon freshly ground white pepper
  • Olive oil for drizzling

For the filling:

  • 3 tablespoons olive oil
  • 3 garlic cloves finely chopped
  • 1-½ cups sliced mushrooms
  • ¾ pound medium-size shrimp peeled and deveined, reserve any liquids
  • ½ pound sea scallops cut into 1/4-inch thick slices, reserve any liquids
  • ½ pound cod thawed if using frozen, cut in 1/2-inch cubes
  • ½ pound salmon thawed if using frozen, cut in 1/2-inch cubes
  • ¼ cup fresh lemon juice from 1 to 2 lemons
  • 3 cups shredded mozzarella cheese
  • 2 tablespoons chopped fresh Italian parsley for garnishment


  • Preheat the oven to 350°F
  • Prepare a 9×12 oven-proof baking dish with olive oil or non-stick spray, reserve.
  • Cook the noodles according to the package directions. Transfer the drained noodles to a large plate or baking sheet that has been lined with plastic wrap. Cover with another sheet of plastic wrap to keep them from drying out. (see notes)

For the béchamel sauce:

  • Heat the milk in a saucepan and keep it warm while you prepare the rest of the ingredients.
  • Melt the butter in a large saucepan over medium heat.
  • Add the flour to the butter, and cook stirring, until the flour is well incorporated, about 4 minutes.
  • Slowly whisk in the hot milk. Mix well and bring to a boil. Cook until the sauce becomes thick, about 10 minutes. Stir in the nutmeg, salt, and white pepper. Remove the sauce from the heat and drizzle a little olive oil on top to keep it from forming a skin. Set aside until needed.

For the filling:

  • Heat the olive oil in a large sauté pan over medium-high heat. Add the mushrooms and garlic and cook just until the garlic is fragrant.
  • Add the shrimp, scallops (and their liquid, if any), cod and salmon. Cook just until the shrimp begins to turn pink.
  • Add the reserved béchamel sauce and bring just to a boil, gently mixing the sauce with the seafood. Remove from the heat and stir in the lemon juice.

To Assemble:

  • Add ¼ cup of the seafood sauce to the bottom of the dish.
  • Arrange ⅓ of the noodles on the sauce, cutting to fit the dish. Spoon ¼ of the seafood sauce on the pasta then ½ cup of shredded mozzarella cheese.
  • Repeat with the remaining layers, finishing with mozzarella cheese then sprinkle the parsley on top.
  • Bake until heated through, about 35 minutes. Remove from the oven and allow to rest for 15 minutes before serving.


  • To prevent the boiled noodles from sticking together spray them with oil before stacking them or place parchment paper between them. Cover them with plastic wrap so they don’t dry out while you make the sauce and filling.
  • Want to skip boiling the noodles? This recipe also works well with fresh lasagna noodles or No-bake noodles. Fresh lasagna noodles can be found in the refrigerator section of most grocery stores.

Sounds great. Do you need to add extra liquid if you use oven ready lasagna noodles?
