What’s in this Seafood Lasagna Recipe?
This is the kind of meal you pay top dollar for at your favorite seafood grill. Layers of crab, shrimp, and scallops, oh my! Its just too good to be true.
- Canola Oil: Helps the veggies sear without burning. Any neutral oil works.
- Unsalted Butter: Adds rich, creamy flavor to the sauce.
- Green Onions: Lighter in flavor than traditional onions, these complement shellfish super well!
- Garlic: Adds a bit of earthiness.
- Chicken Broth: Forms the base of the sauce and helps the seafood cook gently.
- Clam Juice: Adds a distinctive seafood flavor. You can sub with more chicken broth if you prefer.
- Seafood: A combination of bay scallops, shrimp, and crabmeat makes this lasagna hearty and delicious!
- Black Pepper: Adds a touch of spice.
- All-Purpose Flour: Helps thicken the sauce.
- Half-and-Half: Makes the sauce creamy.
- White Wine: Cuts the creaminess of the sauce and enhances the seafood flavors. You’ll want to use a semi-dry to dry white wine, not a sweet one!
- Kosher Salt: Enhances the flavors of the dish.
- Crushed Red Pepper Flakes: Adds a slight kick!
- Cheese: Parmesan, Italian blend, and mozzarella cheese are light enough in flavor to complement the seafood without overpowering it.
- Lasagna Noodles: You’ll need oven-ready, no-boil noodles to separate the layers.
Pro Tip: The quality of the seafood you use will impact the overall taste of the dish. Fresh or high-quality frozen seafood will give the lasagna a better flavor.
Variations on Seafood Lasagne
This seafood lasagna is absolutely delicious as is, but here are a few ways to change it up just a bit!
- Substitute the crab meat in the recipe with slightly sweeter lobster meat.
- Add spinach and ricotta cheese to the layers of the seafood lasagna for an even creamier lasagna with healthy greens!
- Use salmon in place of the crab meat or shrimp. This gives the lasagna a rich and buttery flavor.
- Try making this lasagna with Alfredo sauce. It’s similar to the bechamel here, but it has a slightly cheesier flavor.
- Add artichoke hearts to the layers of the lasagna. The tanginess of the artichokes complements the sweetness of the crab.
Absolutely! Just make sure to thaw it completely and remove any excess water before using it in the recipe.
Seafood lasagna can be made ahead of time and refrigerated or frozen. Just make sure to cover it tightly with foil or plastic wrap before storing it in the fridge or freezer.
Yes, you can substitute the type of seafood used in the recipe to your preference. Just make sure to adjust the cooking time for the seafood accordingly.
Yes, you can make seafood lasagna without cheese if you have dietary restrictions or prefer not to use cheese.
To prevent your seafood lasagna from being too watery, make sure to drain excess liquid from the seafood before adding it to the recipe. You can also use less sauce and bake the lasagna uncovered for the last 10-15 minutes of baking time to allow the excess liquid to evaporate.
How to Store and Reheat
Store leftover lasagna wrapped tightly in plastic wrap or aluminum foil in the refrigerator for up to 3 days.
Reheat in a 350°F oven covered with foil for 20-30 minutes, or until warmed through. Remove the foil and bake for an additional 5-10 minutes to brown the cheese on top, if desired.
How to Freeze
Freeze seafood lasagna tightly wrapped in 2 layers of plastic wrap and 1 layer of aluminum foil for up to 3 months. Let thaw overnight in the refrigerator before reheating.

Becky’s Tips
- The quality of the seafood you use will impact the overall taste of the dish. Fresh or high-quality frozen seafood will give the lasagna a better flavor.
- It’s important to pre-cook the seafood before adding it to the lasagna. This will ensure that it’s cooked properly and doesn’t become overcooked and rubbery in the oven.
- Season the seafood and sauce: Seafood can be delicate in flavor, so be sure to season it well to allow the flavor to shine through.
- Once the lasagna is done baking, let it rest for at least 10-15 minutes before slicing it. This will allow the layers to set and the lasagna to hold together better when sliced and served.

I’m about to make this recipe today, for Easter. After baked and frozen, what is your suggestion about reheating on Easter morning? Should I defrost overnight in the refrigerator for Sunday morning and what amount of time and oven temp do you recomend to reheat?
We recommend thawing overnight in the refrigerator before reheating in a 350°F oven for 20-30 minutes, or until warmed through to 165°F internally.
Hi, Becky–I am retraining myself how to cook wonderful recipes after years of hardly cooking at all. I have just 2 quick questions for you, please: (1) would it be OK to substitute some other liquid for the chicken broth?? And (2) what about the potential of adding fresh baked bacon to this recipe?? I am most concerned about question (1), because I don’t like anything associated with chicken!! And the bacon is just a thought/question; not necessary!! Many thanks for your help, and all the best!! :-) Anne
Hi Anne, any kind of broth would work, but we recommend vegetable broth or seafood broth over beef broth! You could totally add bacon!
Thanks so much, Samantha–your advice is very helpful!! :-)
I doubt bacon would work well in this recipe. Seafood has a delicate flavor, and the white sauce has a delicate flavor. Bacon is a loud and bold flavor that would overpower everything else.
I want to try make a seafood lasagna soup with this recipe. Do you think I can thin out the roux using seafood or chicken broth for a good soup base?
We haven’t tried that, Danielle, but it might work!
I love the idea of this but I worry that the seafood is being cooked twice.
Based on all the wonderful reviews, I am planning to make this tomorrow for friends but am having trouble understanding step two. It think there is a misprint as it is asking for the green onion to be cooked along with the garlic, then it says to add the onions again along with 10 tblsp butter,oil and and more onions and garlic. Am I misunderstanding something?
Hi Gloria, the light gray text under each step is the ingredients that are linked to the step. We are unable to divide them out with this feature, so follow the black text in the step for the exact amounts.
Thank you Becky! I am just starting prep on the recipe so your prompt reply is so appreciated!
Thanks for the recipe. I decided to make this on the fly for our 19th Anniversary. A couple of things. Use a 12 x 7 pan to make it. Not sure why you chose 9 x 9. All lasagna pans are bigger because the noodles are 12″. When I tried the step of butter and flower to mix that together, what I wound up with in 30 seconds was a bunch of flower/butter balls. When I added the half and half and seafood fluid, then I could get everything to blend. I almost thing it would be better to mix the flour a half cup of half and half, kind of like making pancake mix. Add that to the butter. Then add the seafood sauce. I also added ricotta cheese and spinach. I also used a mozarella ball rather than shredded mozarella. In either case we both enjoyed it and had an enjoyable anniversary dinner.
Hi Jeff, mixing the butter and flour together creates what’s called a roux, which should thicken up considerably, then thin back out once mixed with more liquids. It sounds like yours worked perfectly! Glad to hear you enjoyed this recipe!
