How to Make Seafood Lasagna Creamy Cheese
-
Prepare Seafood: In a large skillet, melt 2 tablespoons of butter over medium heat. Lightly sauté shrimp, scallops, and crab, along with minced garlic and finely chopped shallots, until opaque—about 3-4 minutes. Remove from heat to prevent overcooking.
-
Make Béchamel Sauce: In a saucepan, melt the remaining butter on medium-low. Whisk in flour to form a roux, cooking for about a minute. Gradually add warmed milk, whisking continuously until the sauce thickens, usually 5-7 minutes. Season with salt, pepper, and a pinch of nutmeg.
-
Mix Cheese Filling: In a mixing bowl, combine ricotta cheese, grated Parmesan, chopped parsley, lemon zest, salt, and pepper. Stir until well mixed and creamy.
-
Assemble Lasagna: Preheat your oven to 375°F (190°C). In a generously buttered baking dish, spread a layer of béchamel, followed by noodles, a layer of the ricotta mixture, seafood, and shredded mozzarella. Repeat these layers, finishing with a top layer of béchamel and a generous sprinkle of mozzarella.
-
Bake: Cover the dish with foil and bake for 30 minutes. Remove the foil and continue baking for an additional 10-15 minutes until the top is golden and bubbly. Allow the lasagna to rest for 10 minutes before slicing.

Seafood Lasagna Creamy Cheese Recipe FAQs
How do I select seafood for my lasagna?
Absolutely! When choosing seafood, look for fresh shrimp, scallops, and crab that have a mild ocean scent. The shrimp should have a firm texture and a vibrant color. Avoid any seafood with a strong fishy odor or dark spots, as these are signs of spoilage.
What is the best way to store leftover seafood lasagna?
Very! Allow your seafood lasagna to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days. When you’re ready to enjoy it again, simply reheat it in a preheated oven at 350°F (175°C) for around 20 minutes, ensuring it’s thoroughly warmed.
Can you freeze seafood lasagna?
Absolutely! To freeze, wrap the assembled lasagna tightly in plastic wrap followed by aluminum foil to prevent freezer burn. This way, it can stay fresh for up to 2 months. When you’re ready to bake it, thaw it overnight in the refrigerator before reheating at 375°F (190°C) until heated through, which usually takes about 30-40 minutes.
Why is my lasagna watery or mushy?
Great question! A common cause for watery lasagna is excess moisture from the seafood. Be sure to pat your seafood dry before sautéing, and avoid overcooking the ingredients. Letting the lasagna rest before slicing is also crucial; this allows the layers to set and prevents a watery mess.
Is this recipe suitable for people with allergies?
Very! If you’re concerned about allergies, you can modify the recipe easily. For example, if someone has a shellfish allergy, you can use only one type of seafood or substitute them with flaked white fish. Additionally, ensure the dairy ingredients used don’t contain any hidden allergens.
How can I enhance the flavor of my seafood lasagna?
Definitely! To boost the flavor profile, consider adding some fresh herbs like basil or thyme to the béchamel sauce. A splash of white wine while sautéing the seafood can also elevate the dish wonderfully. If you enjoy a little heat, try adding crushed red pepper flakes for a spicy kick!
