How to Make Seafood Lasagna with Shrimp and Crab
-
Preheat your oven to 375°F (190°C). Grease a 9 × 13-inch baking dish generously to prevent sticking and help the lasagna cook evenly.
-
Cook the lasagna noodles according to package directions until al dente. Drain them thoroughly and set aside, ensuring they don’t stick together.
-
Sauté the shrimp by heating olive oil in a skillet over medium heat. Add shrimp and cook for 2–3 minutes per side until they turn pink and opaque. Combine with crab and set aside.
-
Prepare the creamy sauce by melting butter in a saucepan over medium heat. Add minced garlic and cook for about 30 seconds until fragrant.
-
Whisk in flour and cook for 1 minute, stirring constantly to avoid lumps. Gradually whisk in the milk. Keep cooking for 4–6 minutes, stirring until the mixture thickens and coats the back of a spoon.
-
Stir in the grated Parmesan cheese, Italian seasoning, and salt until nicely blended and the cheese has melted.
-
Combine ricotta cheese with the egg in a bowl until smooth and creamy, creating a cohesive mixture for your lasagna layers.
-
Layer your lasagna by spreading a thin layer of creamy sauce in the bottom of the greased baking dish. Add 4 noodles, then top with ⅓ of the ricotta mixture, the seafood blend, fresh spinach, another layer of sauce, and a sprinkle of mozzarella cheese.
-
Repeat the layers two more times, finishing with a generous layer of sauce and the remaining mozzarella on top, creating a beautiful, cheesy crown.
-
Cover the dish with foil and bake in your preheated oven for 25 minutes. Remove the foil and continue baking for an additional 15–20 minutes, until the top is bubbling and golden brown.
-
Rest for 10–15 minutes before slicing your lasagna to allow the layers to set, making for cleaner cuts.
Optional: Garnish with freshly chopped parsley for a pop of color and extra flavor.

Gluten-Free: Opt for gluten-free lasagna noodles to ensure everyone can enjoy this seafood delight. They’ll work just as well, allowing you to savor every layer.

Expert Tips for Seafood Lasagna
Noodle tips: Always cook lasagna noodles al dente; they will continue to soften as they bake, preventing your layers from becoming mushy.
Seafood selection: For the best flavor, use the freshest shrimp and crab meat you can find. Frozen seafood can work, but thaw it properly beforehand.
Sauce consistency: Ensure your sauce thickens to a coat-the-spoon consistency. If it’s too runny, your lasagna won’t hold its shape.
Layering correctly: Spread your ingredients evenly for balanced bites. Use a spatula to help evenly distribute the seafood and sauce across the noodles.
Resting time: Don’t skip the resting period after baking! This allows your seafood lasagna with shrimp and crab to set, making slicing easier and more enjoyable.
Freezing advice: If you want to make ahead, assemble but don’t bake. Cover tightly and freeze; then bake straight from the freezer, adding extra time as needed.
Make Ahead Options
These Seafood Lasagna with Shrimp and Crab layers are ideal for meal prep, allowing you to enjoy a gourmet experience without the day-of hustle! You can prepare the entire lasagna up to 24 hours in advance by assembling the layers and covering them tightly with foil, which helps maintain moisture and flavor. If you want to prep the components instead, cook the noodles and sauté the seafood and prepare the sauce; these can be stored in the refrigerator for up to 3 days. When ready to bake, simply layer everything together, pop it in a preheated oven, and enjoy a delicious, homemade meal with minimal effort!
How to Store and Freeze Seafood Lasagna with Shrimp and Crab
Room Temperature: It’s best to avoid leaving seafood lasagna out for more than 2 hours to maintain freshness and avoid any food safety issues.
Fridge: Store leftover seafood lasagna in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven for best results!
Freezer: For longer storage, freeze unbaked lasagna tightly wrapped in plastic wrap and aluminum foil for up to 2 months. Bake directly from the freezer, adding about 10–15 minutes to the cooking time.
Reheating: When reheating, cover with foil to prevent the top from burning. Heat until warmed through, about 20 minutes at 350°F (175°C). Enjoy your delicious seafood lasagna with shrimp and crab any day!

Seafood Lasagna with Shrimp and Crab Recipe FAQs
What type of seafood should I use for seafood lasagna?
Absolutely! While shrimp and crab are fantastic, you can customize the seafood based on your preferences. You may want to consider scallops, lobster, or even mussels for a delightful twist. Just be sure to adjust cooking times to ensure everything is perfectly cooked and safe to eat.
How should I store leftover seafood lasagna?
Very easily! To keep your seafood lasagna fresh, store it in an airtight container in the fridge for up to 3 days. If you want to reheat it, I recommend using the oven at 350°F (175°C) for even heating. Just cover it with foil to prevent the top from burning!
Can I freeze seafood lasagna?
Absolutely! You can either freeze it unbaked or baked. If freezing unbaked, wrap it tightly in plastic wrap and then in aluminum foil, ensuring no air gets in, and it will keep for up to 2 months. When you’re ready to bake, cook it straight from the freezer, adding about 10–15 extra minutes to the baking time.
Why is my lasagna watery? What can I do?
Very commonly, a watery lasagna can result from excess moisture in the vegetables or seafood. To avoid this, I suggest sautéing spinach beforehand to release water or, if using other veggies, pat them dry with a paper towel. Always ensure your sauce is thick before layering.
Can my seafood lasagna be made ahead of time?
Absolutely! You can assemble your seafood lasagna with shrimp and crab up to a day in advance. Just cover it tightly with plastic wrap and store it in the fridge. When you’re ready to bake, allow it to sit at room temperature for about 30 minutes before popping it in the oven.
Is it safe to leave seafood lasagna out at room temperature?
No, it’s best to avoid leaving seafood lasagna out for more than 2 hours to maintain freshness and food safety. Bacteria can grow rapidly in warm temperatures, so always ensure it’s cooled down and stored properly after serving.
