Step‑by‑Step Instructions for Creamy Seafood Lasagna
Step 1: Preheat and Prepare
Preheat your oven to 180°C (350°F) and grease a 9 x 13-inch baking dish with butter or cooking spray. This ensures that your creamy seafood lasagna will not stick as it bakes. Having your dish ready and the oven preheating sets the stage for creating a delightful meal.
Step 2: Make the Bechamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once melted, whisk in 4 tablespoons of flour and cook for about 1 minute to form a roux. Gradually whisk in 2 cups of milk until the mixture thickens, which should take about 5–7 minutes. Stir in ½ cup of freshly grated Parmesan cheese until melted and creamy, then remove from heat.
Step 3: Prepare the Cheese Mixture
In a bowl, combine 15 ounces of ricotta cheese, 1 whisked egg, 2 tablespoons of dried parsley, and a pinch of salt. Mix until the ingredients are well blended and smooth, creating a luscious filling that complements the layers of your seafood lasagna.
Step 4: Sauté the Seafood
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add your seafood mix (such as shrimp, scallops, and crab) and season lightly with salt and pepper. Cook for about 3–4 minutes until the seafood is just cooked through and opaque. Remove from heat to preserve its tender texture.
Step 5: Assemble the Lasagna
Spread a thin layer of the bechamel sauce at the bottom of your greased baking dish. Place lasagna noodles on top, followed by a layer of the ricotta mixture, then a layer of the sautéed seafood, and more bechamel sauce. Repeat these layers two more times, ensuring an even distribution for your creamy seafood lasagna.
Step 6: Add the Final Touches
Once your layers are completed, top the final layer with a generous amount of shredded mozzarella cheese and any remaining Parmesan cheese. This will create a beautifully bubbly and golden crust as it bakes, enhancing the savory flavor of your seafood lasagna.
Step 7: Bake to Perfection
Carefully place the assembled lasagna in the preheated oven and bake for approximately 35 minutes. Keep an eye on it; once the top is golden brown and bubbling, it’s time to take it out. If it is browning too quickly, you can cover it with foil midway through baking.
Step 8: Cool and Serve
Once baked, allow your seafood lasagna to cool for about 5-10 minutes before slicing. This resting period helps the layers set, making it easier to serve. Enjoy each comforting bite, filled with creamy textures and delicious seafood flavors!

Make Ahead Options
These creamy Seafood Lasagna layers are perfect for meal prep, saving you valuable time on busy evenings! You can assemble the entire lasagna up to 24 hours in advance. To prepare ahead, simply complete all layers, cover tightly with plastic wrap, and refrigerate. This helps keep the ingredients fresh and allows the flavors to meld beautifully. When ready to bake, remove from the fridge and let it sit at room temperature for about 30 minutes (to prevent sudden temperature changes) before placing it in the preheated oven. Your Seafood Lasagna will still be just as delicious and comforting, perfect for a delightful family meal!

Seafood Lasagna Recipe FAQs
How do I choose the best seafood for my lasagna?
Absolutely! For the freshest flavors, select seafood that smells briny and sweet, with no strong fish odor. Look for shrimp that are firm and have a slight sheen, or crab meat that is lump-free. Aim for a mix of seafood—like shrimp, scallops, and even crab—to add a delightful variety to your creamy Seafood Lasagna.
How should I store leftover seafood lasagna?
Very simple! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Just make sure it’s completely cooled before sealing. This way, the flavors will remain intact, and you’ll be ready for delicious leftovers!
