How to Make Seafood Lasagna

Making seafood lasagna may sound fancy, but the steps are surprisingly simple. Follow this guide to layer, bake, and serve a dish that feels restaurant-quality but is easy enough for a cozy night in.

Step 1: Prep the Seafood

In a skillet over medium heat, warm 1 tbsp olive oil. Add shrimp, scallops, and white fish. Sauté for 3–4 minutes until just cooked. Remove from heat and set aside.

Step 2: Make the Cream Sauce

In a saucepan, melt 4 tbsp butter. Stir in 1/4 cup flour to make a roux. Gradually whisk in 3 cups milk and 1/2 cup seafood broth. Stir constantly until thickened, about 5–7 minutes. Add 1 tsp salt, 1/2 tsp black pepper, and 1 tsp dried basil. Remove from heat.

Step 3: Prepare Cheese Filling

In a bowl, mix 1½ cups ricotta, 1 egg, 1/2 cup Parmesan, and a pinch of salt. Set aside.

Step 4: Sauté Aromatics

In a pan, heat 1 tbsp olive oil. Add 1 chopped onion and 3 cloves minced garlic. Cook until soft and fragrant, about 3–5 minutes.

Step 5: Assemble the Lasagna

In a 9×13-inch baking dish:

1. Spread a thin layer of cream sauce on the bottom.
2. Layer 3 noodles.
3. Spread half the ricotta mixture, a third of the seafood, sautéed aromatics, mozzarella, and sauce.
4. Repeat the layers.
5. Top with the final 3 noodles, sauce, mozzarella, and the remaining Parmesan.

Step 6: Bake

Cover with foil and bake at 375°F for 25 minutes. Uncover and bake another 10–15 minutes until bubbly and golden on top.

Step 7: Rest and Serve

Let the lasagna rest for 10–15 minutes before slicing. This helps the layers set and makes serving easier.

You Must Know

Before you start layering, there are a few things worth knowing to make your seafood lasagna come out just right.

• Dry Your Seafood: Pat shrimp, scallops, and fish dry after thawing. Extra moisture can make your lasagna soggy.
• No Thin Sauce: A good béchamel should be thick enough to coat the back of a spoon. Too thin? Let it simmer a bit longer.
• Use Low-Sodium Broth: Since seafood and cheese are already salty, a low-sodium seafood or veggie broth keeps things balanced.
• Shred Cheese Fresh: Pre-shredded cheese doesn’t melt as smoothly. For the creamiest texture, grate your own mozzarella and Parmesan.
• Rest After Baking: Let the lasagna sit 10–15 minutes before slicing. This helps it firm up and hold its layers.

These small steps go a long way toward a creamy, flavorful lasagna that slices clean and tastes amazing.

Perfecting the Cooking Process

Seafood lasagna is all about timing and balance, and here’s how to nail it:

• Lightly Cook Seafood First: Just sauté the shrimp, scallops, and fish until barely cooked. They’ll finish in the oven.
• Sauce Comes First: Always start your layers with sauce on the bottom to prevent sticking and add flavor.
• Don’t Overload Layers: Even though it’s tempting, too much filling makes it fall apart. Stick to moderate portions.
• Cover, Then Uncover: Bake covered for the first 25 minutes to lock in moisture, then uncover for the last 10–15 to brown the top.
• Let It Rest: Again—it’s important! Resting makes slicing easier and keeps the layers looking neat.

Follow these tips, and your seafood lasagna will look and taste like it came straight from a cozy, coastal restaurant.

Add Your Touch

Seafood lasagna is already impressive, but you can easily make it your own with a few smart tweaks:

• Switch Up the Seafood: Not a fan of scallops? Use lump crab meat or more shrimp. Prefer a lighter touch? Go with just white fish and a veggie or two.
• Add Vegetables: Sautéed spinach, mushrooms, or even zucchini slices can add flavor and color. Just make sure they’re cooked and drained to avoid extra moisture.
• Try Different Cheeses: Mozzarella and Parmesan are classic, but feel free to mix in fontina, provolone, or even a touch of goat cheese for a bold spin.
• Use Fresh Herbs: Toss in chopped basil, parsley, or chives between layers for a pop of freshness.
• Go Gluten-Free: Substitute gluten-free lasagna noodles and double-check your broth and flour. The results are just as creamy and satisfying.

Whether you’re feeding picky eaters or experimenting with flavors, this recipe is flexible enough to handle your creative spin while staying true to its cozy, coastal vibe.

Storing & Reheating

How to Reheat:

• Microwave: Place a slice on a microwave-safe plate, cover with a damp paper towel, and heat in 1-minute bursts until warmed through.
• From Frozen: Thaw in the fridge overnight first. Then reheat using the oven method for the best results.

With the right storage and reheating, you’ll enjoy every last bite—even days later.

• Prep Everything First: Chop, measure, and get your ingredients ready before you start cooking. It makes the whole process smoother and stress-free.
• Use Oven-Ready Lasagna Noodles: These save time and soak up the sauce perfectly. If you use regular noodles, cook them al dente to avoid mushiness.
• Layer Smartly: Start with a little sauce at the bottom, then go noodles → ricotta mix → seafood → béchamel → mozzarella. Repeat for even flavor.
• Taste As You Go: Especially your béchamel and seafood—season with salt, pepper, and a pinch of paprika or Italian seasoning as needed.
• Avoid Overbaking: Bake until bubbly and golden on top—no more. Overbaking can dry out seafood and make the cheese rubbery.
• Clean Cuts Matter: Use a sharp knife and a spatula to slice clean squares after resting. It’ll look great and hold together better.

These tips are simple but powerful, helping you serve up a lasagna that’s rich, balanced, and restaurant-worthy.
