Seafood Lasagna
There’s something undeniably comforting about a bubbling tray of lasagna coming out of the oven, but when you take that classic and give it a coastal twist with succulent seafood, the magic truly begins. This seafood lasagna is rich, creamy, and packed with flavors that transport you straight to a seaside trattoria. Imagine layers of tender pasta, plump shrimp, scallops, and crab, all wrapped in a luscious béchamel and topped with melted cheese. Trust me, you’re going to love this.
Behind the Recipe
This dish came to life on a chilly Sunday afternoon when the craving for something cozy collided with a longing for the ocean. I had just come back from the market with a bag full of fresh seafood and no desire to make the usual pasta dishes. That’s when the idea struck — why not layer all these ocean treasures into a creamy, cheesy lasagna? A few tests later, and this became a family favorite.
Recipe Origin or Trivia
Seafood lasagna isn’t as widely known as its beefy cousin, but it’s been gracing Italian coastal kitchens for generations. In regions like Liguria and Sicily, seafood-based pastas and baked dishes are staples. This variation takes inspiration from those regions but adds a creamy béchamel, more commonly used in Northern Italian cooking. It’s a beautiful fusion of Italy’s diverse culinary landscape.

Chef’s Pro Tips for Perfect Results
Here’s what I’ve learned from making this beauty more times than I can count:
- Use partially cooked noodles: It saves time and absorbs flavor during baking.
- Drain seafood well: Excess moisture will make your lasagna watery, so pat dry your shrimp and scallops before cooking.
- Layer with intention: Start and end with sauce for the ultimate creamy bite.
- Fresh herbs matter: A sprinkle of chopped parsley or basil adds brightness to the richness.
- Let it rest: Resist diving in right away. Let it sit for 10–15 minutes to firm up.

Large Skillet: For sautéing seafood and veggies.
Medium Saucepan: To prepare the béchamel sauce.
9×13 Baking Dish: The perfect size for layering everything.
Whisk: Essential for smooth béchamel.
Spatula or Ladle: For layering sauce and spreading fillings.

Texture & Flavor Secrets
This lasagna is a harmony of contrasts. The soft, velvety noodles soak up the creamy béchamel, while the seafood bursts with delicate briny flavor. The cheeses melt into gooey bliss, with a golden crust on top that adds just the right touch of crunch. It’s rich, savory, and fresh all at once.

- Use oven-ready noodles to skip boiling.
- Mix the ricotta with an egg for extra creaminess and structure.

- Don’t overcook the seafood. Just a quick sear is enough before layering.
What to Avoid
A few pitfalls to steer clear of for perfect results:
- Overcooking seafood: It’ll turn rubbery, so keep it just barely done before baking.
- Skipping the rest time: Cutting too early will make it fall apart.
- Overloading layers: Less is more when layering. Keep it balanced.

Make-Ahead and Storage Tips
This is one of those dishes that works beautifully ahead of time. You can assemble it up to a day in advance and refrigerate it until baking. Leftovers keep well in the fridge for 3 days and reheat best in the oven. It also freezes like a charm — just wrap tightly and freeze before baking, then cook straight from frozen, adding 15–20 minutes extra.
How to Serve Seafood Lasagna
Pair this rich dish with something light and zippy. A lemony arugula salad, roasted asparagus, or even just some warm baguette makes it a well-rounded meal. And don’t forget a squeeze of fresh lemon right before serving — it wakes everything up.
Creative Leftover Transformations
Got extras? Here’s how to enjoy them again in new ways:
- Slice and pan-fry leftovers for crispy edges.
- Dice and turn into stuffed bell peppers.
- Use in a creamy seafood soup base.
- Cube it into a savory bread pudding-style brunch bake.
Additional Tips
Here are a few more secrets from my kitchen to yours:
- A sprinkle of red pepper flakes on top gives a lovely kick.
- Use a mix of mozzarella and fontina for extra meltiness.
- Add a layer of wilted spinach for more depth and nutrients.
- Always taste the béchamel before assembling to adjust seasoning.
Make It a Showstopper
Presentation goes a long way. Garnish with chopped parsley or basil, and serve it on a white platter with lemon wedges on the side. A drizzle of olive oil and a few microgreens can make this look straight out of a magazine.
Variations to Try
Here are a few ways to put your own twist on it:
- Spicy Cajun Seafood Lasagna: Add Cajun seasoning to the béchamel and seafood mix.
