- Canola oil: Perfect for cooking the seafood gently without overpowering flavors.

- White pepper: Provides gentle warmth and spice without disrupting the delicate flavors.
- All-purpose flour: The staple thickener critical for making the white sauce silky smooth.
- 2% Milk: Keeps the sauce creamy but balanced, avoiding heaviness.
- Salt: Essential for seasoning and bringing out the layers of flavor.

How to Make Seafood Lasagna with Shrimp, Scallops, and Crab Recipe
Step 1: Cooking the Seafood
Start by heating canola oil and butter in a large skillet until the butter melts. Add the finely chopped green onion and sauté until tender and fragrant, which kick-starts the aromatic foundation of this dish. Then, pour in chicken broth and clam juice, bringing the mixture to a gentle boil. Next, add your scallops, shrimp, and chopped crabmeat along with a dash of white pepper for seasoning. Simmer everything uncovered until the shrimp turn that perfect pink and the scallops become firm and opaque—about 4 to 5 minutes. This step ensures your seafood stays tender and juicy without overcooking. Don’t forget to drain the seafood but keep that flavorful cooking liquid—it’s pure gold for making the sauce.
Step 2: Making the White Sauce
In a separate saucepan, melt your remaining butter and whisk in the flour until you’ve created a smooth paste—it’s the base for your creamy sauce. Gradually whisk in a blend of milk and the reserved seafood cooking liquid, then season with salt and the rest of the white pepper. Bring this mixture to a boil while stirring continuously; it will thicken to a perfect sauce consistency in just a couple of minutes. Once thickened, take it off the heat and fold in heavy whipping cream and half the Parmesan cheese. Reserve about three-quarters of this sauce to mix into the seafood, and keep the rest handy for layering the lasagna.
Step 3: Building the Seafood Lasagna with Shrimp, Scallops, and Crab Recipe
Preheat your oven to 350°F and gather all your components like a pro. Grease a 13×9-inch baking dish and start by spreading half a cup of the white sauce on the bottom. Place three cooked lasagna noodles on top, then layer half of your luscious seafood mixture onto that. Follow it with about 1 1/4 cups of white sauce. Repeat these layers to build the body of your seafood masterpiece. Finish by topping with the remaining noodles, the last of the white sauce, and a generous sprinkling of Parmesan cheese. If you want an easy shortcut, no-bake lasagna noodles work beautifully here.
Step 4: Baking to Perfection
Place the lasagna in the oven, uncovered, and bake until the top has turned a gorgeous golden brown—about 35 to 40 minutes. Once baked, don’t rush the resting time! Let it stand for at least 15 minutes before cutting, which lets the layers meld and keeps everything from sliding apart. If you like, finish with more chopped green onions and Parmesan for a fresh, cheesy finish that guests will adore.
How to Serve Seafood Lasagna with Shrimp, Scallops, and Crab Recipe
Garnishes
A sprinkle of fresh chopped green onions adds a vibrant color and mild crunch that contrast beautifully with the creamy texture of the lasagna. Additional Parmesan cheese dusted on top before serving melts slightly and brings out a nutty richness that complements the seafood perfectly. A few bright lemon wedges on the side can also add a refreshing zing when squeezed over individual portions.
Side Dishes
This seafood lasagna makes a hearty main course, so keep the sides light and fresh to balance the meal. A crisp mixed greens salad with a tangy vinaigrette or a simple arugula salad with shaved Parmesan works wonders. Garlic bread or a crusty baguette is also perfect for soaking up any extra sauce, adding a comforting carb element that everyone loves.
Creative Ways to Present
For an elegant touch, serve your seafood lasagna in individual ramekins or mini baking dishes—this not only looks stunning but makes serving mess-free and personal. Alternatively, layering a small salad on the plate with a drizzle of infused olive oil or a sprinkle of fresh herbs like parsley can elevate the presentation and flavor experience. For a festive occasion, scatter edible flowers or chopped chives as a garnish to make your plate truly pop.
Make Ahead and Storage
Storing Leftovers
Leftover seafood lasagna is just as delightful the next day and can be stored covered in the refrigerator for up to 3 days. Make sure it’s tightly wrapped or in an airtight container to keep it fresh and prevent the seafood aromas from mingling with other foods.
Freezing
This recipe freezes beautifully, making it a perfect make-ahead dish. Wrap individual portions or the entire lasagna tightly with plastic wrap and aluminum foil to protect against freezer burn. It can be frozen for up to 2 months and still retain that wonderful texture and flavor upon thawing.
Reheating
Reheat your seafood lasagna gently in the oven at 325°F, covered with foil to maintain moisture, for about 20-25 minutes if thawed. For quicker reheating, microwave individual servings on medium power in short bursts, stirring occasionally to heat evenly without drying out the seafood or sauce.
FAQs
Can I use fresh crab instead of imitation crabmeat?
Absolutely! Just add fresh cooked crab meat after cooking the scallops and shrimp to prevent overcooking. The imitation crab is convenient and flavorful, but fresh crab elevates the dish to a luxurious level.
Is it okay to substitute heavy cream with half-and-half?
You can, but keep in mind that heavy cream adds richness and body to the sauce that half-and-half can’t fully replicate. The texture might be a bit lighter but still tasty if you want a lower-fat option.
Can I prepare the seafood mixture in advance?
Yes, you can cook the seafood mixture a few hours ahead and refrigerate it. Just keep it covered and bring it to room temperature before layering to ensure even baking.
What kind of wine pairs best with this seafood lasagna?
A crisp, citrusy white wine like Sauvignon Blanc or a lightly oaked Chardonnay pairs beautifully, complementing the creamy sauce and seafood flavors without overpowering them.
Can this recipe be made gluten-free?
Definitely! Use gluten-free lasagna noodles and substitute the all-purpose flour in the white sauce with a gluten-free flour blend or cornstarch. The flavors will remain just as delightful!

White Sauce
- 1/2 cup all-purpose flour
- 1 1/2 cups 2% milk
- 1/2 teaspoon salt
- 1/8 teaspoon white pepper
- 1/2 cup plus 2 tablespoons butter, divided
- 1 cup heavy whipping cream
- 1/2 cup shredded Parmesan cheese, divided

- 9 lasagna noodles, cooked and drained
Instructions
- Cook the seafood: In a large skillet, heat canola oil and 2 tablespoons of butter. Once the butter has melted, add the chopped green onion and cook until tender. Stir in the chicken broth and clam juice and bring to a boil. Add the bay scallops, shrimp, imitation crabmeat, and 1/8 teaspoon white pepper. Return the mixture to a boil, then reduce heat and simmer uncovered until the shrimp turn pink and scallops are opaque and firm, about 4 to 5 minutes. Drain the seafood, reserving the cooking liquid, and set the seafood mixture aside.
- Make the white sauce: In a large saucepan, melt the remaining butter (approximately 1/2 cup minus 2 tablespoons). Stir in the flour until smooth. Gradually whisk in the mixture of milk and reserved seafood cooking liquid until fully combined. Add salt and the remaining 1/8 teaspoon white pepper. Bring the sauce to a boil, stirring until thickened, about 2 minutes. Remove from heat and stir in the heavy cream and 1/4 cup of Parmesan cheese. Reserve 3/4 cup of this white sauce to stir into the seafood mixture, keeping the rest for layering.
- Combine seafood with sauce: Stir 3/4 cup of the prepared white sauce into the seafood mixture until evenly combined.
- Preheat oven: Preheat your oven to 350°F (175°C). Prepare a greased 13×9-inch baking dish.
- Assemble the lasagna: Spread 1/2 cup of the white sauce on the bottom of the baking dish. Layer three cooked lasagna noodles on top. Spread half of the seafood mixture over the noodles, followed by 1 1/4 cups of white sauce. Repeat with another three noodles, the remaining seafood mixture, and another 1 1/4 cups of white sauce. Finish by topping with the last three noodles, the remaining white sauce, and sprinkle with the remaining Parmesan cheese.
- Bake the lasagna: Bake uncovered for 35 to 40 minutes or until the top is golden brown and bubbly. Remove from oven and let stand for at least 15 minutes before cutting.
- Serve: Optionally, garnish with additional chopped green onions and extra shredded Parmesan cheese before serving.
Notes
- To check if shrimp are cooked, look for a pink color and a curled, C shape.
- If using real crab instead of imitation crabmeat, avoid cooking it in the broth; add it later to the seafood mixture.
- For convenience, no-bake lasagna noodles can be substituted for cooked noodles.
- Letting the baked lasagna rest before cutting helps it set and prevents a watery texture.
