A seafood lasagna story: the perfect Sunday dinner

I first tried seafood lasagna at a small coastal restaurant on a vacation years ago, and it was love at first bite. I wasn’t sure how I felt about the idea of seafood in such a classic Italian dish, but I was blown away. The flavors were fresh and vibrant, yet comforting and cozy—exactly what I needed after a day at the beach. Ever since then, I’ve been experimenting with my own version, tweaking it here and there to perfect it for my family’s taste. The smell of garlic, butter, and herbs always takes me back to that little restaurant. Now, this has become one of my go-to “wow” dishes for Sunday dinners or when I want to impress at a family gathering. It’s packed with flavor but also offers a touch of elegance, making it a winner every time.

Where did seafood lasagna come from?

Seafood lasagna is a variation of the classic Italian dish, lasagna, which originated in the Emilia-Romagna region of Italy. Traditionally, lasagna is made with layers of pasta, meat, and a béchamel or ricotta-based sauce. But along coastal regions, seafood is often swapped in for the meat, adding a light and fresh spin on the hearty classic. The practice of using seafood in lasagna probably came from seaside towns where fresh fish and shellfish were in abundance. Over the years, the dish has evolved and adapted to various local tastes. In some versions, you might find it made with a tomato-based sauce, while others, like ours, use a creamy béchamel to complement the delicate seafood flavors.

Let’s talk ingredients: the stars of this lasagna

Every ingredient in this seafood lasagna plays a key role, and it’s important to get the best quality you can find.

• Shrimp: Adds a sweet, firm texture to the lasagna. Be sure to get raw, peeled, and deveined shrimp for convenience. You can also substitute lobster if you’re feeling extra indulgent.
• Flounder: A mild, flaky white fish that soaks up all the flavors of the sauce. Cod or sole are good alternatives if you can’t find flounder.
• Scallops: These little morsels are tender and bring a sweet, briny flavor to the dish. If you can, go for dry-packed sea scallops. If you’re out of scallops, you can use chunks of lobster or even crab meat for a similar vibe.
• Mushrooms: Their earthy flavor balances the richness of the seafood and sauce. Feel free to swap them with baby spinach or zucchini if you want more greens.
• Béchamel Sauce: Creamy, velvety, and rich—this is what brings everything together. It’s a classic French sauce that is easy to make and gives the lasagna that luscious texture. Don’t skip it!
• Cheese: Swiss and parmesan add that golden, bubbly top we all crave. Gruyere would be an amazing substitute for Swiss if you’re feeling fancy.

Each ingredient adds a layer of flavor, and there’s plenty of room for substitutions if needed. Just try to keep the balance between fresh and rich!

Kitchen gear: what you need (and what you can totally skip)

Let’s make sure you’ve got everything you need to pull off this delicious seafood lasagna. Don’t worry—nothing too fancy is required.

• 9×13 casserole dish: This is your lasagna’s home. If you don’t have this exact size, you can use any similar-sized baking dish. Just make sure it has deep sides to accommodate all those layers.
• Large skillet: You’ll need this to cook the seafood and the mushrooms. A non-stick or cast iron pan would be ideal, but any good-sized skillet will do.
• Medium saucepan: This is for your béchamel sauce. If you don’t have a medium saucepan, use a small pot—just make sure it’s deep enough for stirring.
• Whisk: A whisk will help you get a smooth béchamel sauce. If you don’t have one, a fork will work in a pinch—just keep stirring!

Aside from that, you’ll need basic utensils like a slotted spoon, cutting board, and knives. And if you want to save time, pre-chopped onions and garlic are your friends.

Step-by-step: making seafood lasagna with ease

Let’s dive into the steps! Don’t rush—this is the kind of recipe where slow and steady wins the race. Here’s how to make it:

1. Start with the béchamel sauce: Melt the butter in a medium saucepan, then whisk in the flour. You’re looking for a smooth, golden paste. Slowly add the milk while whisking to avoid lumps. Keep stirring until it thickens (about 5-7 minutes), then season with salt and pepper. This is the glue that holds everything together, so make sure it’s silky smooth.Tip: If your sauce turns out a bit too thick, just add a splash more milk to loosen it up.
2. Cook the seafood: In a large skillet, melt some butter and sauté the onion and garlic until fragrant. Add your shrimp, scallops, and flounder, seasoning with salt and pepper. Cook just until the shrimp turns pink—don’t overdo it! You want the seafood to stay tender.Mistake I’ve made before? Overcooking the seafood. Just remember that it’ll cook more in the oven later!
3. Mushrooms and sauce: Remove the seafood with a slotted spoon, leaving the juices in the pan. Add your mushrooms and cook them down until they’re golden and soft. Then stir in the béchamel, crushed tomatoes, cream, and herbs. Let it simmer for a few minutes to meld those flavors together. This is the heart of your lasagna sauce!
4. Layering it up: Preheat your oven to 375°F. Butter a 9×13 dish, then start layering. First goes a thin layer of sauce, then a third of your seafood mixture. Top with three lasagna noodles, followed by more sauce and cheese. Repeat the layers until everything is used up, finishing with a final sprinkle of Swiss and parmesan on top.
5. Bake to bubbly perfection: Bake the lasagna for about 40-50 minutes, or until it’s golden, bubbling, and your kitchen smells like a seaside bistro. Let it rest for a few minutes before cutting into it (I know, this part is hard!).

Fun variations you’ll love to try

This seafood lasagna is fantastic as-is, but I love playing around with different variations based on what’s in season or who I’m cooking for. Here are a few ideas:

• Gluten-free version: Swap out the regular lasagna noodles for gluten-free ones, and use a gluten-free flour for the béchamel. The result? Just as creamy and flavorful!
• Vegan seafood lasagna: For a plant-based version, you can use vegan “shrimp” and “scallops” (they’re surprisingly good these days!) and a dairy-free béchamel sauce made with almond milk and vegan butter.
• Zesty lemon twist: Add a bit of lemon zest to the béchamel sauce for a fresh, bright kick that pairs beautifully with the seafood.
• International flair: Want a Mediterranean twist? Add some chopped sun-dried tomatoes and a handful of capers to the sauce. Or try an Asian-inspired version by swapping the béchamel for a coconut milk-based sauce and adding a touch of curry powder. The possibilities are endless!

Serving suggestions: wow your guests

When it comes to serving, you’ll want this lasagna to be the star of the show. I like to garnish it with extra parsley for a pop of color and some fresh lemon wedges on the side to brighten up the flavors. Serve with a light green salad tossed with a simple vinaigrette to balance the richness of the lasagna. A loaf of warm, crusty bread is also perfect for soaking up any leftover sauce (trust me, you’ll want to).

drink pairings that complement seafood

I recommend something light and refreshing to complement the creamy and savory nature of the seafood lasagna. A sparkling water with a twist of lemon or lime is always a great choice. If you prefer something a bit sweeter, an iced herbal tea, like chamomile or hibiscus, would be perfect. If you’re feeling a little fancy, try making a citrus spritzer with fresh orange juice, a splash of club soda, and a sprig of mint. These drinks will cut through the richness without overpowering the delicate seafood flavors.

Storing and reheating tips

If you’re lucky enough to have leftovers, seafood lasagna stores beautifully! Place it in an airtight container and keep it in the fridge for up to three days. When reheating, I recommend doing so in the oven at 350°F for about 20 minutes to ensure it heats evenly without drying out. If you’re in a rush, the microwave will work too—just cover the dish with a damp paper towel to keep it from drying out.

Adjusting the recipe for different serving sizes

This recipe as written serves about 8 people, but if you need to adjust it, no problem! For a smaller crowd, you can halve all the ingredients and use a smaller baking dish. If you’re feeding a large group, you can easily double it—just be aware that you may need to bake it slightly longer to heat through. Either way, the lasagna holds its structure well, so it’s perfect for feeding a crowd.

Troubleshooting: friendly advice for common issues

If your sauce is too thick, add more milk or cream to loosen it up. If your lasagna turns out watery, it might be because the seafood released extra liquid. Try patting the seafood dry before cooking to avoid this. And don’t worry too much if your layers don’t look perfect—the beauty of lasagna is that it always tastes amazing, no matter how it looks!
