Step-by-Step Instructions

Make the Béchamel Sauce:
Melt butter in a medium saucepan over medium heat until bubbling but not browned. Whisk in flour and cook for one minute to remove raw taste. Gradually pour in milk while whisking constantly. Continue to stir until the mixture thickens and coats the back of a spoon. Stir in parmesan until smooth and set aside.
Mix the Cheese Filling:
In a bowl combine ricotta mozzarella egg parsley and salt. Stir until the mixture is creamy and fully blended. This filling will add richness to each layer.
Cook the Seafood:
Heat olive oil in a skillet over medium high heat until shimmering. Spread the seafood mix in a single layer. Season with salt pepper and parsley. Cook for three minutes just until the seafood starts to turn opaque. It will finish cooking in the oven.
Layer the Lasagna:
Grease a baking dish and spread a thin layer of béchamel sauce over the bottom. Place lasagna sheets in a single layer. Spoon one third of the ricotta filling evenly over the pasta followed by one third of the seafood. Pour one third of the remaining béchamel on top. Repeat the layering twice more. Finish with mozzarella and a sprinkle of parmesan.
Bake and Rest:
Preheat oven to 375 degrees Fahrenheit. Bake uncovered for 35 minutes or until golden and bubbling. Cover with foil if the top browns too fast. Let rest for 10 minutes before cutting so the layers hold together.

My favorite part is the seafood mix I first learned to use it while visiting coastal Italy where a grandmother showed me how to cook it gently before baking. That moment changed the way I prepare seafood forever.

Seafood Selection Tips

Quality seafood matters most in this dish. Visit a local fish counter for the freshest selection. Choose firm white fish shrimp and scallops for the best texture blend. If using frozen make sure it is fully thawed and dry before cooking to avoid excess moisture.

Heat olive oil in a large skillet over medium-high heat until shimmering. Add seafood mix in a single layer. Season with salt, pepper, and parsley. Cook for 3 minutes, just until lightly colored but not fully cooked through.

Step 04

Spread a thin layer of béchamel on the bottom of a greased baking dish. Layer fresh lasagna noodles over the sauce. Spread one-third of the ricotta mixture, then one-third of the seafood, followed by one-third of the remaining béchamel. Repeat layers twice more. Finish with mozzarella and a sprinkle of parmesan.

Preheat oven to 375°F (190°C). Bake the assembled lasagna for 35 minutes until the top is golden and bubbling. Cover loosely with foil if browning too quickly after 20 minutes. Let rest for 10 minutes before slicing and serving.
