So, I decided to combine a classic lasagna dish with an amazing seafood recipe to create this to-die-for seafood lasagna recipe! This creamy seafood lasagna is loaded with your favorites—shrimp, crab, and a ton of lobster meat.

Now, maybe you’re thinking… seafood and cream sauce? Seafood and cheese?! Cousins. You’re talking to the lady who madeseafood baked ziti,crab alfredo, andcrawfish mac and cheese, for goodness sake! If there’s one thing Cousin Rosie can do, it’s make a bomb.com creamy seafood recipe.

What Is Seafood Lasagna with White Sauce?

This fantastic seafood lasagna recipe is the best of two worlds. It’s layered like a classic lasagna dish, but you have a creamy mix of seafood and bechamel sauce instead of a meaty red sauce. Everything is seasoned to perfection, the lasagna noodles are cooked perfectly to al dente, and it has a whole lot of cheese. The cream sauce is rich and garlicky, and the seafood mixture is seasoned with the one and only Old Bay Seasoning. If you’re a seafood lover, you can’t help but fall in love with this white seafood lasagna!

Ingredients for Creamy Seafood Lasagna

You can find my complete list of ingredients and measurements in the recipe card at the end of this post. Here are the simple ingredients you need to make a homemade seafood lasagna.

• Seafood: I use a mixture of lobster meat, crab meat, and fresh shrimp.
• Green Onion: puts a little bit of a fresh bite in the lasagna.
• Seasoning: this dish is packed with flavors from Old Bay (you can use your favorite seafood seasoning), garlic, pepper, and Italian seasoning.
• Butter, Heavy Cream, Flour: these three ingredients build the rich white sauce that makes the lasagna oh-so-creamy.
• Lasagna Noodles: cooked perfectly to al dente.
• Italian Cheese Blend: yes, I use apre-shredded cheese blend; it’sa shortcut!

Ingredient Variations for Seafood Lasagna

Now, usually, I tell y’all to follow my recipe to a T if you want greatness, but in every great recipe, there’s a little wiggle room to do what youlove. I know y’all are going to ask me about substitutions, so let me offer you some of my faves.

What other types of seafood can I use in seafood lasagna?

You can use imitation crab meat, canned shrimp or frozen shrimp instead of fresh, crawfish, scallops, or salmon! It may sound weird, but clam juice really boosts the seafood flavor if you’re into that. You can use all fresh seafood or stick with frozen—just make sure everything is well-thawed before you layer it into the lasagna. Can’t find one of the ingredients I used? Leave it out or swap it out!

Can I use no-boil lasagna sheets in seafood lasagna?

Yes, you most certainly can!Oven-ready lasagna noodles are a godsend if you’re short on time. No boiling is needed; just layer them into the lasagna like normal, bake, and they come out perfect.

If you want to omit the lasagna noodles altogether… well, now that’s straight up a different recipe. However, youcantransform this into seafood pasta by using rotini or penne pasta. Going low-carb? Try layering zucchini noodles instead!

I don’t want to make a homemade bechamel sauce; what else can I use?

If you’re going for semi-homemade or don’t have time to stir together a rich cream sauce, sub it with your favorite jarred alfredo sauce. This recipe doesn’t call for ricotta cheese, but if you want to go the more traditional lasagna route, you can use a ricotta mixture for the creamy layers.

Cousin Rosie… there are no vegetables in this seafood lasagna! What vegetables can I add?

I gotchu Cousins! Peas, diced carrots, mushrooms, or onions all go great with seafood. Of course, you can’t go wrong with fresh spinach and cream sauce.

I don’t want to use pre-shredded cheese; what’s the best cheese blend in seafood lasagna?

The Italian blend I use has Parmesan cheese, mozzarella cheese, Provolone, Fontina, Romano, and fresh asiago. If you want to go with freshly shredded cheese, I’d recommend a simpler blend of Parmesan, mozzarella, and provolone.

The Seafood Mixture

The first step is the flavorful seafood mixture. Mix everything in a large bowl—the green onions, lobster, crab, and shrimp—and season it with your favorite seafood seasoning. You can’t go wrong with classic Old Bay seasoning, but I also have my very ownRosamae Seasonings Seafood Magic seasoningthat is outta-this-world delicious.

The Cream Sauce

Next, grab a large skillet to make the from-scratch béchamel sauce. What the heck is a béchamel sauce anyway? Creamy, rich GOODNESS. Melt butter in a large saucepan or skillet, then whisk in your all-purpose flour. The skillet should be over medium heat so the flour doesn’t burn. Once mixed, slowly add the heavy cream, whisking constantly to avoid lumps.

Toss in your seasoning: fresh minced garlic, salt, black pepper, and Italian seasonings. Whisk and cook the sauce until it thickens—it should only take a few minutes! Once it’s done, you’re ready to layer.

Assemble the Lasagna

Grab your casserole dish and spray it down with non-stick cooking spray. Then, spread a thin layer of sauce in the bottom of the dish. Here is the specific layer order I want you to follow:

• First Layer: Sauce, noodles, half of the seafood mixture
• Second Layer: Sauce, shredded cheese, noodles, other half of the seafood mixture
• Third Layer: Sauce, noodles, shredded cheese, parsley flakes (optional)

So, you should have used 9 lasagna noodles—bottom, middle, and top—between layers of cream sauce and lots of cheese. Imagine how GOOD this will taste when it’s hot and bubblin’, y’all!

Cover the seafood lasagna with foil and toss that baby in the oven for 1 hour and 25 minutes. If you want that cheesy top layer to get perfectly golden brown, remove the foil for the last 5-10 minutes of cooking time.

This amazing seafood lasagna recipe is perfect for special occasions, adinner party, large family gatherings… you name it!

How to Store Leftover Seafood Lasagna

You can store leftovers in an airtight container for up to 5 days in the fridge. You can make a whole pan of this lasagna and toss it in the freezer, tightly wrapped, and it will store for up to three months. Just make sure to thaw it completely before baking to avoid watery, runny lasagna.

What to Serve with Seafood Lasagna

Need some side dish ideas? Like most Italian recipes, seafood lasagna pairs well with bread—homemade dinner rolls, breadsticks, or garlic bread. I’d also serve a fresh green salad or someroasted veggies.
