Seafood in Lasagna, does it make sense?
Well over 30 years ago, I first came across a recipe for a seafood lasagna. The very first thought that came to my mind was it didn't sound right. I was thinking seafood and cheese in a lasagna form did not belong together.
Then, as time went on, we started eating chicken alfredo. The first time I ate Shrimp Alfredo, I realized, seafood lasagna really wasn't that far fetched of an idea. After all, alfredo is a creamy cheesy white sauce and it went great with linguini, which is pasta.
I decided to up the ante a little bit and use some Old Bay Seasoning in the alfredo sauce. Old Bay Seasoning a blend of seasonings that pairs extremely well with seafood and chicken. It has a distinct flavor that is just a little bit spicy.

What you need to make Seafood Lasagna
Because I made this for my non-keto family to enjoy, I used no-boil lasagna noodles. However, I have made this completely keto by making this low carb pizza crust recipe and cutting it into lasagna strips after baking.
I used a seafood trio blend of shrimp, calamari, and bay scallops. You can use any combination of seafood you wish, or just use your favorite seafood.
Old Bay Seasoning is a must in this recipe. It complements the seafood perfectly and is delicious in the alfredo sauce.
Cheeses that are used in a regular lasagna recipe, ricotta, and mozzarella. I stuck with those cheeses for this recipe.
Make this recipe your way
- Use your own combination of seafood. Shrimp, crab, scallops, lobster, any will do.
- Save time by buying pre-cooked seafood and skip the section of cooking the seafood mixture.
- Swap out the mozzarella and parmesan cheese for your favorites. Havarti, Monterey Jack, Gouda are all good cheeses to go with the seafood.
- If you prefer to use regular lasagna noodles, cook 6 noodles according to package, cut the noodles in half and proceed with the recipe. Use 3 noodles that have been cut in half for each layer.
