Seafood Lasagna Recipe Ingredients
For the Lasagna
- Lasagna Noodles – Essential for structure; no-boil noodles can be used for convenience.
- Alfredo Sauce – Forms the creamy base; feel free to use store-bought for an easy option.
For the Seafood
- Large Shrimp – Adds sweetness and texture; ensure they’re deveined for the best results.
- Fresh Crab Meat – Provides a delicate, flaky flavor; scallops or fish are great substitutes.
For the Sauce and Seasoning
- Olive Oil – Ideal for sautéing; can be swapped with butter for a richer taste.
- Garlic – A fragrant boost; fresh is best, but garlic powder works in a pinch.
- Salt and Black Pepper – Essential for flavor enhancement; adjust according to taste.
- Red Pepper Flakes (optional) – Gives a hint of heat; skip if you prefer a milder flavor.
For the Cheesy Layers
- Ricotta Cheese – Adds creaminess and body; mix with herbs for a fresh finish.
- Shredded Mozzarella Cheese – Topping with good stretch; can be substituted with provolone.
- Freshly Grated Parmesan Cheese – For nuttiness and depth; while pre-grated works, fresh is preferred.
For Final Touches
- Heavy Cream – Enriches the sauce for a silky finish; milk is a lighter alternative but less creamy.
- Fresh Parsley – Brings brightness; you can swap for basil or other fresh herbs for variety.
- Panko Breadcrumbs – Adds a delightful crunch; standard breadcrumbs also work, but panko is lighter.

Step‑by‑Step Instructions for Creamy Seafood Lasagna Recipe
Step 1: Prepare Seafood
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Sauté 2 minced garlic cloves until fragrant, about 1 minute. Add 1 pound of deveined large shrimp and season with salt, black pepper, and red pepper flakes to taste. Cook until the shrimp turn pink, approximately 3-4 minutes. Remove the shrimp from the skillet and gently warm 8 ounces of fresh crab meat in the same pan for 2-3 minutes, then set aside.
Step 2: Enhance Alfredo Sauce
In a medium saucepan, combine 2 cups of Alfredo sauce with 1 cup of heavy cream over low heat. Stir continuously until the mixture is warmed through, about 5 minutes. Gradually add 1 cup of shredded mozzarella and 1/2 cup of freshly grated Parmesan cheese, stirring until the cheeses melt and the sauce is smooth and creamy. This rich sauce will serve as the backbone of your creamy seafood lasagna.
Step 3: Prepare Ricotta Mixture
In a mixing bowl, combine 15 ounces of ricotta cheese, 1/2 cup of shredded mozzarella, the remaining 1/4 cup of Parmesan cheese, and 2 tablespoons of chopped fresh parsley. Mix well until all ingredients are well incorporated. Taste the mixture and adjust seasoning with salt and pepper as needed. This will create a flavorful, creamy layer that enhances the overall richness of the seafood lasagna.
Step 4: Assemble Lasagna
Preheat your oven to 375°F (190°C). In a greased 9×13 inch baking dish, spread a thin layer of the warmed Alfredo sauce on the bottom. Layer three to four lasagna noodles over the sauce, followed by half of the ricotta mixture, half of the sautéed seafood, and a generous drizzle of more Alfredo sauce. Repeat the layers, finishing with a final layer of noodles topped with the remaining Alfredo sauce.
Step 5: Bake Lasagna
Sprinkle 1 cup of shredded mozzarella and 1/2 cup of panko breadcrumbs evenly over the top of the lasagna. Cover the baking dish with foil and bake for 30 minutes. After this time, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and bubbling. Let the creamy seafood lasagna rest for 10 minutes before slicing and serving.

Make Ahead Options
These Creamy Seafood Lasagna creations are perfect for busy weeknights and meal prep enthusiasts! You can assemble the entire lasagna up to 24 hours in advance—cover tightly with foil or plastic wrap to prevent drying and maintain freshness. The seafood, like shrimp and crab, can also be cooked and stored in the refrigerator for up to 3 days before layering. When it’s time to bake, simply preheat your oven, remove any coverings, and increase the baking time by about 10-15 minutes if it’s coming straight from the fridge. This time savings means you can still serve a restaurant-quality meal with minimal effort!

Expert Tips for Perfect Seafood Lasagna
- Quality Seafood: Always choose fresh or frozen seafood to enhance flavor and texture. Overcooking will make it rubbery; watch your cooking times closely.
- Sauce Thickness: If using homemade Alfredo, ensure it’s thick enough to hold the layers together. A watery sauce can lead to a soggy lasagna.
- Layering Technique: Alternate layers wisely—start with sauce, noodles, ricotta, seafood, and end with noodles and sauce on top for a beautiful finish.
- Resting Period: Letting the assembled seafood lasagna rest in the fridge for a few hours allows flavors to meld beautifully before baking.
- Serving Temperature: Allow the lasagna to cool for about 10 minutes after baking. This helps each slice hold its shape and makes for easier servings.
- Make-Ahead Convenience: Consider preparing your seafood lasagna recipe up to 24 hours in advance. Just remember to adjust the baking time if it’s chilled!

Creamy Seafood Lasagna Recipe FAQs
What type of seafood is best for this recipe?
