There’s plenty of ricotta, Parmesan and mozzarella cheese in this recipe plus some spinach and a buttery bread crumb topping.

This seafood lasagna is absolutely loaded with seafood. There’s one pound of shrimp, one pound of scallops, and 1 pound of crab. It  makes a huge amount. Because it is so rich, you will want to cut it in small pieces. It can easily feed 9 or more people.

Like most lasagna recipes, this recipe takes a little time to assemble, but it is well worth the effort.


  1. Cook the lasagna noodles. Jump to the next step while the water comes to a boil.
  2. Cook the seafood. First cook the shrimp and then the scallops so you don’t crowd the pan. Just cook them about halfway. They will finish cooking in the oven. Once they are cooked, remove them from the pan and cook the garlic. Add the wine and lemon juice and then the crab. Return the shrimp and scallops and set the mixture aside.
  3. Make the cheese sauce.
  4. Mix together the ricotta/spinach mixture.
  5. Layer the lasagna.
  6. Bake for 20 minutes.
  7. Add the topping and bake another 20 minutes.

Recipe Tips:

If you wish, leave the scallops out and just use shrimp and crab. I would use twice as many shrimp.

If the shrimp are large, cut each one in half so that they are bite-sized.

You can easily cut the recipe in half and bake it in a 9-inch square pan.

Be very careful not to overcook the shrimp and scallops. You just want them partially cooked becasue they will finish cooking in the oven.

Let the lasagna sit for 15-20 minutes before slicing it.

Note: I couldn’t find any bay scallops and used large sea scallops instead. I cut each one in 4 pieces and it worked pretty well.

    A really excellent recipe, so tasty and creamy. Other than adding two bay leaves in the cheese sauce mix I followed as written. Superb.

  2. I am have made thelis twice now and nothing times my guests raved about it. When ever I make lasagna I always remove most of the water in the ricotta by place it flat between two paper towels. Once they are wet I replace the paper towels and repeat until they are barely wet. This keeps the lasagna from being runny.

  3. This looks perfect to satisfy my vegetarian Thanksgiving guests. How does this do if prepared the day before and reheated? The oven is pretty much spoken for on T-day, but could throw this in about 45 minutes before dinner time. Thanks

    Could you use no bake lasagna noodles? I have used these exclusively since they were invented.
