It’s a labor of love that results in a restaurant-quality meal right from your own kitchen.
Recipe Details
- Flavor Profile: Rich, buttery, and savory with bright notes of fresh parsley and a hint of garlic.
- Textures: Tender lasagna noodles layered with a silky white sauce, succulent seafood, and bubbly melted cheese.
- Total Time: Approximately 30 minutes prep plus 40 minutes baking and 20 minutes resting.
- Difficulty Level: Intermediate; requires preparing a white sauce and careful layering.
What You’ll Need
For the base, you will need 1 pound of lasagna noodles. The creamy white sauce is made from 4 tablespoons of butter, 1/4 cup plus 1 tablespoon of flour, and 3 cups of milk, seasoned with 1/2 cup of parmesan, salt, and white pepper. The cheese layer features a 15 oz container of ricotta, an egg, garlic, parsley, and 2 cups of mozzarella. The star ingredients are 1 pound each of cooked shrimp and crabmeat.
Ingredient Notes
- Cooked Seafood – It is essential that both your shrimp and crab are fully cooked before assembly. If your shrimp are large, chop them into bite-sized pieces to ensure even distribution in every layer.
- White Pepper – Using white pepper instead of black pepper is a professional culinary trick for white sauces; it provides the same spicy kick without adding dark specks to the creamy sauce.
- Ricotta Mixture – Adding an egg to your ricotta acts as a binder, ensuring that the cheese layers stay in place and don’t become too runny when the lasagna is sliced.
- Crabmeat – Lump crabmeat provides the best texture, but high-quality claw meat or even imitation crab can be used depending on your preference and budget.
Add-ins and Substitutions
- Scallops – For an even more decadent version, add 1/2 pound of bay scallops along with the shrimp and crab.
- Spinach – Layer in some sautéed, well-drained spinach for a pop of color and extra nutrition.
- Spices – Add a pinch of ground nutmeg to the white sauce to enhance the creaminess and add a traditional Italian flair.
How to Make Creamy Seafood Lasagna
1. Prepare the Pasta Cook the 1 pound of lasagna noodles according to the package directions. Drain them and separate them immediately to prevent sticking.
2. Whisk the Parmesan Béchamel In a saucepan over medium heat, melt the 4 tablespoons of butter. Add the 1/4 cup plus 1 tablespoon of flour and whisk until smooth. Gradually pour in the 3 cups of milk, whisking continuously until the sauce thickens. Turn off the heat and stir in 1/2 cup of parmesan cheese, 1/2 tablespoon of salt, and 1/4 tablespoon of ground white pepper.
3. Mix the Cheese Layer In a medium bowl, combine the 15 oz of ricotta cheese, the egg, 2 teaspoons of minced garlic, 2 cups of the mozzarella cheese, and 1/2 cup of chopped parsley. Stir until well combined.
4. Prepare the Seafood In a separate bowl, toss together the 1 pound of cooked shrimp (chopped if large) and the 1 pound of crabmeat.
5. Assemble the Layers Grease a 9 x 13 inch baking pan. Spread 1 cup of the white sauce on the bottom. Place 3 noodles side by side. Top with 1/3 of the ricotta mixture, followed by 1/3 of the seafood mixture. Repeat this process two more times. Finish the top with the remaining white sauce, the remaining 1/2 cup of mozzarella, and the remaining 1/2 cup of parmesan.
6. Bake and Set Cover the pan with foil and bake at $350^{\circ}F$ for 30 minutes. Remove the foil and bake for an additional 10 minutes, or until the top is bubbly and golden brown.
7. Rest Before Serving Remove the lasagna from the oven and allow it to rest for at least 20 minutes. This is a crucial step; it allows the sauces and cheeses to set so you can cut clean, beautiful squares.
Pro Tip: To prevent the cheese from sticking to the foil during the first part of baking, lightly spray the underside of the foil with nonstick cooking spray before covering the pan.
Recipe Tips
- Noodle Management – To keep noodles from sticking while you prep, lay them flat on a piece of parchment paper or the edge of a clean colander.
- Sauce Consistency – If your white sauce becomes too thick while sitting, whisk in a tablespoon or two of warm milk to loosen it back up before layering.
- Fresh Parsley – Use flat-leaf Italian parsley for a more robust flavor than curly parsley.
FAQs
Can I use un-cooked no-boil noodles? Yes, but you will need to add about 1/2 cup more milk to the sauce, as the dry noodles will absorb more moisture during the baking process.
How do I store leftovers? This lasagna stores beautifully in the refrigerator for up to 3 days. Reheat individual slices in the oven at $325^{\circ}F$ or in the microwave.
Can I use frozen seafood? Absolutely. Just ensure the seafood is fully thawed and very well-drained. Any excess water from the seafood will make the lasagna watery.
Serving Suggestions
- Sides – Serve with a crisp Caesar salad or roasted asparagus with lemon to cut through the richness of the white sauce.
- Bread – A warm, crusty loaf of garlic bread or a simple baguette is perfect for soaking up any extra cream sauce.
- Wine Pairing – A chilled glass of Chardonnay or Pinot Grigio pairs excellently with the buttery seafood flavors.
Make This Recipe in Advance
You can assemble the lasagna up to 24 hours in advance. Keep it tightly covered in the refrigerator. When you are ready to eat, bake as directed, though you may need to add 5-10 minutes to the covered baking time since you are starting from a cold temperature.

- 1 lb cooked crabmeat
The Parmesan Béchamel
- 4 tbsp butter

- 2 cups mozzarella cheese, grated
- 1/2 cup chopped parsley
The Topping
- 1/2 cup mozzarella (reserved), 1/2 cup parmesan (reserved)
Instructions
Sauce: Melt butter and whisk in flour. Gradually add milk, whisking until thickened. Stir in parmesan, salt, and white pepper.
Cheese: Mix ricotta, egg, garlic, 2 cups mozzarella, and parsley.
Assemble: Grease 9×13 pan. Spread 1 cup sauce. Layer 3 noodles, 1/3 ricotta mix, and 1/3 seafood. Repeat twice.
Bake: Top with remaining sauce and reserved cheeses. Bake covered at 350°F for 30 mins; uncover and bake 10 mins more until golden.
