This Seafood Lasagna Recipe takes about 25% less active cooking time than traditional meat lasagna, as seafood cooks much faster than ground beef or sausage. The hands-off baking time gives you freedom to prepare a side salad or set the table while it bubbles to perfection.

Step-by-Step Instructions
Step 1: Prepare the Seafood
Clean and devein shrimp, cut into bite-sized pieces. Cut scallops in half if large. Drain canned crab meat or pick through fresh crab for shells. Pat all seafood dry with paper towels to prevent excess moisture in your lasagna.
Step 2: Create the Seafood Base
- Heat olive oil in a large skillet over medium heat.
- Add onions and sauté until translucent, about 3-4 minutes.
- Add garlic and cook for 30 seconds until fragrant.
- Pour in white wine and simmer until reduced by half, about 2-3 minutes.
- Add shrimp and scallops, cooking just until they begin to turn opaque, about 2 minutes.
- Remove from heat and gently fold in crab meat, lemon zest, and parsley.
- Season with salt and white pepper. Set aside to cool slightly.
Step 3: Make the Béchamel Sauce
- Melt butter in a medium saucepan over medium heat.
- Whisk in flour and cook for 1-2 minutes to remove raw flour taste.
- Gradually add warm milk, whisking constantly to prevent lumps.
- Cook until sauce thickens enough to coat the back of a spoon, about 5-7 minutes.
- Stir in nutmeg and Parmesan cheese until melted.
- Season with salt and white pepper. Remove from heat.
Step 4: Assemble the Lasagna
- Preheat oven to 375°F (190°C).
- Spread 1/2 cup of béchamel sauce on the bottom of a 9×13-inch baking dish.
- Place 3 lasagna noodles over the sauce.
- Spread 1/3 of the seafood mixture over the noodles.
- Add 1/3 of the remaining béchamel sauce.
- Sprinkle with 1/2 cup mozzarella and a tablespoon of Parmesan.
- Repeat layers twice more.
- Top with final layer of noodles, remaining béchamel, and cheeses.
Step 5: Bake to Perfection
Cover with foil and bake for 25 minutes. Remove foil and bake for an additional 15-20 minutes until golden and bubbling. For an extra golden top, broil for the last 2 minutes, watching carefully to prevent burning.
Step 6: Rest and Serve
Allow lasagna to rest for 15 minutes before serving. This crucial step helps the layers set and makes slicing much cleaner. Garnish with fresh dill if desired.

Serving Suggestions
Elevate your Seafood Lasagna Recipe with these complementary sides:
- A crisp arugula salad with lemon vinaigrette provides a refreshing contrast to the rich lasagna.
- Garlic bread or focaccia makes the perfect vehicle for soaking up extra sauce.
- Roasted asparagus or broccolini adds color and nutritional balance to the plate.
- A chilled glass of Pinot Grigio or unoaked Chardonnay complements the seafood flavors beautifully.
For a complete dinner party menu, start with a light seafood appetizer like shrimp cocktail and finish with a citrus sorbet to cleanse the palate.

Common Mistakes to Avoid
- Overcooking the seafood: Remember that seafood will continue cooking in the oven. It should be just barely cooked during the initial sauté.
- Using too much liquid: Drain seafood thoroughly to prevent a watery lasagna. Pat dry with paper towels if necessary.
- Skipping the resting period: Cutting into the lasagna immediately will result in a sloppy presentation. The 15-minute rest is non-negotiable!
- Under-seasoning: Seafood and pasta need proper seasoning. Taste your béchamel and seafood mixture before assembling.
- Using strong-flavored cheese: Avoid sharp cheddar or blue cheese, which can overpower the delicate seafood flavors.
Storing Tips for the Recipe
This seafood lasagna keeps beautifully, making it perfect for meal prep:
- Refrigeration: Store leftovers in an airtight container for up to 3 days. The flavors often improve overnight as they meld together.
- Freezing: Freeze individual portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Warm refrigerated portions in a 350°F oven for 15-20 minutes. Add a tablespoon of water before covering with foil to prevent drying out.
- Make-ahead option: Assemble the entire lasagna up to 24 hours in advance, keep refrigerated, and add 10 minutes to the covered baking time.
