Ingredients You’ll Need
Each ingredient in this seafood lasagna was picked not just for flavor but for how they play together to create layers of creamy, savory, and fresh notes. When you shop, look for fresh lump crab meat and good-quality shrimp to get the best taste possible.
- Unsalted butter: Melts well into the roux base for a smooth, creamy sauce without extra salt.
- All-purpose flour: Thickens the sauce perfectly to coat every noodle layer.
- Heavy cream: Adds luxurious richness and balances the seafood flavors beautifully.
- Clam juice: Gives that fresh ocean essence without overpowering the dish.
- Garlic powder and onion powder: A gentle seasoning duo that deepens the sauce’s flavor.
- Ground nutmeg (optional): Just a pinch adds warmth and complexity—trust me, it’s worth trying!
- Italian seasoning: Brings classic herb goodness to the sauce.
- Parmesan cheese: For nutty, sharp notes that melt right into the cream.
- Kosher salt and black pepper: Essential for bringing all the flavors to life.
- Olive oil: Used for sautéing onions and shrimp gently.
- Onion: Adds subtle sweetness and texture to the seafood mixture.

Variations
I love how versatile this recipe can be. You can easily adjust the seafood or the herbs to suit your taste — I’ve played around with adding a bit of lemon zest or swapping crab for lobster on special occasions, and each version has something unique to offer.
- Seafood Swaps: Once, I tried scallops instead of crab, and the texture was just as dreamy—so don’t be afraid to experiment with your favorite shellfish.
- Dairy-Free Version: For a lighter take, I’ve replaced heavy cream with coconut cream and used dairy-free cheese—it’s surprisingly good!
- Herb Twists: Fresh basil or tarragon added at the end can brighten the dish wonderfully if you want a more herbal punch.
- Spicy Kick: If you and your guests like heat, a pinch of red pepper flakes stirred into the sauce really wakes up the flavor.
How to Make Seafood Lasagna Recipe with Shrimp and Crab Recipe
Step 1: Make That Creamy Seafood Sauce
Start by melting butter in a saucepan over medium heat, then whisk in flour until smooth and bubbly—this is your roux. Slowly add heavy cream and clam juice while whisking constantly to avoid lumps. Cook the sauce for about 5-7 minutes until it’s thick enough to coat a spoon. Stir in garlic powder, onion powder, Italian seasoning, nutmeg if you’re using it, parmesan, salt, and pepper. Set this gorgeous base aside; the aroma here already hints at how delicious your lasagna will be.
Step 2: Cook the Shrimp and Sauté the Onion
Heat olive oil in a skillet over medium heat and soften your finely chopped onion for 3-4 minutes until translucent and sweet-smelling. Toss in the shrimp and cook just until they turn pink—any longer and they could get tough. Remove from heat, then fold in the lump crab meat and chopped fresh parsley gently so you keep those delicate crab pieces intact.
Step 3: Layer It Up
Lightly grease a 9×13 baking dish, then start by spreading a thin layer of your seafood cream sauce on the bottom to keep the noodles from sticking. Cover with lasagna noodles, overlapping slightly if needed. Spread a third of your seafood mixture over the noodles, followed by a third of the sauce, then sprinkle a third of shredded mozzarella. Repeat two more times, finishing with noodles, sauce, and cheese on top.
Step 4: Bake Until Bubbly and Golden
Cover the baking dish tightly with aluminum foil, making sure the foil doesn’t touch the cheese (that can cause sticking). Bake at 350°F for 30 minutes, then remove the foil and bake another 15-20 minutes until bubbly and golden on top. Let it rest for about 10 minutes — I’ve learned this step is key to letting the layers settle and making slicing a breeze.
Pro Tips for Making Seafood Lasagna Recipe with Shrimp and Crab Recipe
- Choose Fresh Seafood: Using fresh or well-thawed shrimp and crab really elevates the dish’s texture and flavor.
- Don’t Overcook Shrimp: Shrimp cooks quickly—watch them carefully to keep that tender bite.
- Layer Sauce Generously: I like to make sure each noodle layer is nicely coated so it all melds together perfectly as it bakes.
- Rest Before Serving: Letting the lasagna sit after baking prevents oozing and helps slice cleanly.
How to Serve Seafood Lasagna Recipe with Shrimp and Crab Recipe
Garnishes
Freshly chopped parsley sprinkled on top adds a burst of color and freshness that cuts through the richness. Sometimes I add a little lemon zest or a light drizzle of high-quality olive oil for an extra pop. These simple touches make the presentation feel restaurant-worthy while enhancing the flavors.
Side Dishes
I love pairing this dish with a crisp green salad dressed in a tangy vinaigrette to balance the creamy texture. Garlic-roasted asparagus or simple steamed green beans also work beautifully. For something heartier, a crusty baguette is perfect for mopping up any leftover sauce.
Creative Ways to Present
For a special occasion, try serving this lasagna in individual ramekins for a fancy touch that’s super practical for portion control. Layer it with thin slices of lemon on top under the cheese for an unexpected zing once baked. I’ve also set up a seafood-themed dinner with this as the centerpiece, garnished with edible flowers and fresh herbs, which never fails to impress guests.
Make Ahead and Storage
Storing Leftovers
I usually store leftovers covered tightly in the fridge for up to 3 days. The flavors actually meld more overnight, making the next-day meal even better! Just be sure to keep it sealed well to avoid drying out the edges.
Freezing
This seafood lasagna freezes surprisingly well if you want to prep ahead. After assembling but before baking, I wrap it tightly in foil and plastic wrap. It keeps beautifully for up to 2 months. When you’re ready, just thaw overnight in the fridge and bake as instructed, adding a bit more time covered with foil.
Reheating
To reheat, I prefer the oven to preserve that baked texture—cover the lasagna with foil and warm at 325°F until heated through, about 20 minutes. If you’re pressed for time, the microwave works too but can make it a bit softer.
FAQs
-
Can I use fresh homemade pasta for this seafood lasagna recipe with shrimp and crab recipe?
Absolutely! Fresh pasta can be used, but you’ll want to pre-cook the sheets briefly before layering to prevent sogginess. Oven-ready noodles save time, but fresh pasta will give a tender, delicate texture if you have the time to prepare it.
-
What can I substitute for clam juice if I can’t find it?
If clam juice isn’t available, a combination of low-sodium chicken broth mixed with a splash of white wine or a bit of seafood stock works well. The key is to keep that subtle briny flavor without overpowering the cream sauce.
-
Is this recipe suitable for freezing and meal prepping?
Yes, this seafood lasagna freezes beautifully when assembled but unbaked. Just wrap tightly and store in the freezer for up to 2 months. It’s a lifesaver for meal prepping or hosting last-minute guests.
-
Can I make this recipe dairy-free?
Definitely! Use coconut cream or your favorite dairy-free cream alternatives and replace mozzarella and parmesan with plant-based cheeses that melt well. Expect a slightly different texture, but the flavor will stay delicious.
-
How do I prevent the cheese from sticking to the aluminum foil during baking?
To avoid sticking, make sure the foil doesn’t touch the cheese by tenting it slightly or using a layer of parchment paper between the cheese and foil. This little trick saves the top layer looking beautiful and intact.

This Seafood Lasagna Recipe with Shrimp and Crab Recipe has become one of my go-to dishes when I want to treat myself or impress friends without spending hours in the kitchen.

Description
A creamy and flavorful seafood lasagna layered with shrimp, lump crab meat, and a rich parmesan-infused white sauce, topped with mozzarella cheese and baked to golden perfection.
Ingredients
Sauce
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups heavy cream
- 1 cup clam juice
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon ground nutmeg (optional)
- 1 teaspoon Italian seasoning
- 1/2 cup grated parmesan cheese
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
Seafood Mixture
- 2 tablespoons olive oil
- 1 medium onion, finely chopped
- 8 ounces small shrimp, peeled, deveined, and tail off
- 8 ounces lump crab meat
- 1/4 cup chopped fresh parsley, plus more for garnish
Other Ingredients
- 9–12 oven-ready lasagna noodles
- 4 cups shredded mozzarella cheese
Instructions
- Preheat Oven: Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
- Make the Sauce: In a medium saucepan over medium heat, melt the butter. Stir in the flour and whisk until smooth, cooking for 1 minute to cook out the raw flour taste. Gradually pour in the heavy cream and clam juice while whisking constantly to avoid lumps.
- Thicken Sauce: Continue cooking the sauce for 5 to 7 minutes, stirring often until it thickens and coats the back of a spoon. Stir in garlic powder, onion powder, nutmeg (if using), Italian seasoning, grated parmesan cheese, salt, and pepper. Remove from heat and set aside.
- Cook Seafood Mixture: In a skillet over medium heat, warm the olive oil. Sauté the chopped onion for 3 to 4 minutes until softened. Add the shrimp and cook for 2 to 3 minutes until they just turn pink. Remove the skillet from heat and gently fold in the lump crab meat and chopped parsley.
- Assemble Lasagna: Spread a thin layer of the prepared sauce over the bottom of the baking dish. Arrange enough lasagna noodles to cover the bottom, overlapping slightly if needed. Spread a third of the seafood mixture over the noodles, then a third of the sauce on top, followed by one-third of the shredded mozzarella cheese.
- Layer Repetition: Repeat the layering two more times, finishing with a final layer of noodles, the remaining sauce, and the remaining shredded mozzarella cheese on top.
- Bake Lasagna: Cover the dish tightly with aluminum foil, ensuring it does not touch the cheese. Bake for 30 minutes, then remove the foil and continue baking uncovered for an additional 15 to 20 minutes until the top is golden brown and bubbly.
- Rest and Serve: Allow the lasagna to rest for 10 minutes before serving. Garnish with additional chopped parsley and enjoy.
Notes
- Ensure the sauce is thick enough to hold the layers together but still creamy.
- Oven-ready noodles don’t require pre-cooking, making assembly easier.
- Use fresh parsley for a bright, fresh finish and garnish.
- Seafood should be cooked just until opaque to avoid toughness when baked.
- Covering the dish tightly with foil prevents the top from burning while allowing the inside to cook properly.
- Allow the lasagna to rest so it sets and slices neatly.
