Ingredients for Seafood Lasagna with Shrimp & Crab

Core Ingredients

Here’s what you’ll need to bring this lasagna to life:

• Shrimp – Choose medium-sized shrimp, peeled and deveined. Fresh or frozen both work; just make sure frozen shrimp are fully thawed before cooking.

• Lump crab meat – Go for fresh or high-quality canned crab. Avoid imitation if you can—it’s worth the real deal for flavor.

• Lasagna noodles – Regular or no-boil noodles both work. No-boil makes assembly a breeze.

• Béchamel sauce – Butter, flour, milk, and Parmesan create a silky white sauce that ties everything together. A pinch of nutmeg adds subtle warmth.

• Cheese filling – A mix of ricotta, mozzarella, Parmesan, egg, and fresh parsley for richness and structure.

• Garlic and white wine – For depth and aroma. The wine cooks off but leaves a lovely flavor behind.

Substitutions and Tips

If crab isn’t available, swap in lobster or even scallops for a luxurious variation. Cottage cheese can stand in for ricotta if you prefer a lighter option, though the texture will be slightly different.

Want to sneak in extra veggies? Sautéed spinach, mushrooms, or zucchini slices layer beautifully in this dish. And if you’re in a hurry, no-boil noodles save time without sacrificing quality.

Best Seafood Choices for Lasagna

Not all seafood is created equal when it comes to lasagna. Look for shrimp that are firm and slightly translucent when raw—they’ll cook up juicy and tender. For crab, lump or jumbo lump is ideal for its sweet flavor and satisfying bite. If using canned crab, drain it well to avoid excess moisture.

For the freshest flavors, check your local fish market or seafood counter. Frozen seafood can work in a pinch; just thaw it in the refrigerator overnight and pat dry before cooking to prevent a watery filling.

Kitchen Tools You’ll Need

Must-Have Tools

To make this recipe seamless, have these essentials on hand:

• A 9×13-inch baking dish for layering your lasagna

• A large skillet for cooking the seafood

• A medium saucepan for the béchamel

• Mixing bowls for the cheese filling

• A whisk and spatula for smooth sauces and easy mixing

Nice-to-Have Tools

While not required, a microplane grater is great for fresh nutmeg, and a mandoline can help you add thin veggie layers if you’re experimenting.

How to Make Seafood Lasagna with Shrimp & Crab

This seafood lasagna may look and taste like it came from a fine-dining kitchen, but don’t let that intimidate you. With clear steps and a few helpful tips, you’ll be layering like a pro and pulling a golden, bubbling masterpiece out of the oven in no time.

Step 1 – Prepare the Seafood

Start by melting butter in a large skillet over medium heat. When the butter begins to sizzle, add minced garlic and sauté just until fragrant—about 30 seconds to 1 minute. Be careful not to let it brown; you want gentle flavor, not bitterness.

Add the shrimp to the pan in a single layer. Cook for 2 to 3 minutes per side, just until they turn pink and opaque. Resist the urge to overcook; they’ll finish cooking later in the oven. Toss in the lump crab meat and pour in the white wine if using. Stir gently and cook for another 2 minutes to warm the crab through and let the wine reduce slightly. Season with salt and freshly ground black pepper. Set the seafood aside while you prepare the next components.

Step 2 – Make the White Sauce (Béchamel)

In a medium saucepan, melt butter over medium heat. Whisk in the flour to form a smooth paste, cooking for 1 to 2 minutes to cook out the raw flour taste. This is your roux, and it’s the key to a velvety sauce.

Gradually add the milk, whisking constantly to prevent lumps. Keep stirring until the sauce thickens and coats the back of a spoon, about 5 to 7 minutes. Reduce heat to low and stir in grated Parmesan cheese. Season with salt, pepper, and a pinch of nutmeg to give it that subtle warmth classic to a good béchamel.

Step 3 – Mix the Cheese Filling

In a large mixing bowl, combine ricotta cheese, a beaten egg, shredded mozzarella, grated Parmesan, and freshly chopped parsley. Stir until everything is well incorporated. This mixture brings richness and structure to each layer of your lasagna.

Step 4 – Assemble the Lasagna

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

Spread a thin layer of béchamel sauce over the bottom of the dish to create a moist base. Place lasagna noodles on top, slightly overlapping if needed.

Spoon half of the ricotta mixture over the noodles and spread evenly. Scatter half of the seafood mixture over the cheese layer, then drizzle with more béchamel sauce. Repeat the layers: noodles, remaining ricotta, remaining seafood, more béchamel.

Finish with a final layer of noodles, the rest of the béchamel sauce, and a generous sprinkling of shredded mozzarella. This top layer will bake up golden and bubbly.

Step 5 – Bake

Cover the dish tightly with aluminum foil to prevent the cheese from browning too quickly. Bake for 30 minutes. Remove the foil and bake for an additional 10 to 15 minutes, or until the top is beautifully golden and the lasagna is bubbling around the edges.

Let the lasagna rest for at least 10 minutes before slicing. This helps the layers set so you can serve neat, picture-perfect pieces. Garnish with fresh parsley for a pop of color.

Tips for Success

• Don’t overcook your seafood in the skillet. A quick sauté is enough since it will continue cooking in the oven.

• For a smoother béchamel, warm the milk slightly before adding it to the roux.

• Freshly grated cheese melts better and has superior flavor compared to pre-shredded varieties.

• Let the lasagna rest before slicing. This simple step ensures the layers hold together beautifully.

How to Store and Reheat Seafood Lasagna

At Room Temperature

Allow the lasagna to cool for up to two hours before refrigerating. Leaving it out longer can risk food safety.

In the Refrigerator

Store leftovers in an airtight container or tightly wrapped in the baking dish. It will keep for 3 to 4 days. To reheat, cover with foil and bake at 350°F (175°C) until warmed through, about 20 minutes.

Freezing Tips

This lasagna freezes wonderfully. Assemble the dish but don’t bake it. Wrap tightly in plastic wrap and foil, then freeze for up to 3 months. When ready to enjoy, bake directly from frozen at 350°F for about 1 hour, uncovering during the last 15 minutes.

Frequently Asked Questions

Can I make seafood lasagna ahead of time?

What wine pairs well with seafood lasagna?

A crisp white wine like Chardonnay, Sauvignon Blanc, or Pinot Grigio complements the creamy sauce and delicate seafood flavors perfectly.
