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.

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.
Nutrition Information
I am catering a large gathering and making several different lasagnas. Can I prepare in advance and freeze until the event? It sounds scrumptious.
Yes, you can freeze it. For best texture, I would recommend following the recipe up to the assembly part, but freeze it unbaked. Then defrost and bake to serve.
Can I bake this the day before, let it set up and reheat day 2 for serving? Or would that damage the seafood?
Yes, the seafood will keep fine in the lasagna! Let it cool after baking, cover it tightly and refrigerate, then it’ll be fine to reheat and serve the next day.
I added a few pieces of Cod and also used leeks instead of green onion. Excellent.
Sounds wonderful, Michael!
Well that went over real well. Not much left and this has become the “go to” for seafood lasagna
I love to hear that!
I am confused about the 4 layers and 9 noodles. How many noodles per layer? I hope to make this tomorrow.
Add more if needed to fit your dish!
Hi, This recipe looks amazing! I’d like to try it for a dinner party. I don’t want to be cooking it while my guests are having apps and drinks, so I’d like to prepare it slightly in advance. What do you suggest? Is it OK to prep and let it sit for 3/4 of an hour before I put it in the oven? Thanks,
Fridge for a little bit if needed!
So good! I also added 1lb of crawfish tails and subbed the wine for more 1/2&1/2
Sounds amazing!!
This was a truly delicious, company’s coming, special occasion, wow meal! Hubby loved it and was so glad there was leftovers!
Thanks for sharing, Vicki!
Made this for christmas vacation. It was a hit! I followed the recipe exactly as described except I didn’t have a rectangular pan so I made it a bit taller. It was fantastic. Next time I make this I will use just a little less cheese in the layers…I loved the white sauce!
Looks amazing, Natalie!!
This recipe by far is the best seafood lasagna I have ever tried. I added spinach to the white sauce and only used chicken broth. I also seasoned my seafood and let it marinate for about an hour.
Thanks for sharing, Jolene!
