• 300g shrimp, peeled and deveined
• 300g scallops, patted dry
• 300g white fish fillets (like cod or haddock), cut into bite-sized pieces
• 200g crab meat (fresh or canned, drained)
• 2 tbsp olive oil
• 3 garlic cloves, minced
• 1 small onion, finely chopped
• 1/2 cup dry white wine (optional)
• Salt and black pepper to taste
• 1 tsp dried oregano
• Juice of 1 lemon

Béchamel Sauce

• 4 tbsp unsalted butter
• 4 tbsp all-purpose flour
• 4 cups whole milk, warmed
• 1/4 tsp ground nutmeg
• Salt and white pepper to taste
• 1 cup grated Parmesan cheese

Other Layers

• 12-15 lasagna noodles (no-boil or cooked al dente)
• 3 cups ricotta cheese
• 2 cups shredded mozzarella cheese
• 1 cup grated Parmesan cheese (additional)
• 2 cups fresh spinach, chopped (optional for color and nutrition)
• Fresh parsley or basil for garnish

Step-by-Step Instructions

Prep time takes 30 minutes. Cooking time is 45-50 minutes. Total time: about 1.5 hours.

1. Step 1: Prepare the Seafood

   Heat olive oil in a large skillet over medium heat. Add minced garlic and chopped onion. Sauté for 2-3 minutes until fragrant and soft. Do not brown them.

   Add shrimp and scallops. Cook for 3-4 minutes until they turn pink and opaque. Stir in white fish pieces and crab meat. Pour in white wine if using. Let it simmer for 2 minutes to reduce.

   Season with salt, pepper, oregano, and lemon juice. Cook 1 more minute. Remove from heat. Set aside to cool. This prevents sogginess in the lasagna.

2. Step 2: Make the Béchamel Sauce

   Melt butter in a saucepan over medium heat. Whisk in flour. Stir constantly for 2 minutes to form a roux. It should be smooth and pale.

   Slowly pour in warmed milk while whisking. Keep stirring to avoid lumps. Bring to a gentle simmer. Cook 5-7 minutes until thickened. It coats the back of a spoon.

   Stir in nutmeg, salt, white pepper, and 1 cup Parmesan. Taste and adjust seasoning. Remove from heat. Cover to prevent skin from forming.

3. Step 3: Assemble the Lasagna

   Preheat oven to 190°C (375°F). Grease a 9×13-inch baking dish.

   Spread 1 cup béchamel on the bottom. Layer 3-4 lasagna noodles. Spread 1 cup ricotta evenly. Add one-third of the seafood mixture. Sprinkle chopped spinach if using. Pour 1 cup béchamel over it. Top with 1/2 cup mozzarella and 1/4 cup Parmesan.

   Repeat layers twice more. End with noodles, remaining béchamel, and all remaining cheeses.

4. Step 4: Bake

   Cover with foil. Bake 30 minutes. Remove foil. Bake 15-20 minutes more until bubbly and golden. Cheese browns nicely on top.

   Let rest 15 minutes before cutting. This sets the layers. Garnish with fresh herbs.

Tips for Success

• Choose sustainable seafood. Look for wild-caught shrimp or line-caught fish. Fresh tastes better than frozen, but thawed frozen works well.
• No-boil noodles save time. Ensure enough sauce covers them fully. They absorb liquid during baking.
• Make ahead. Assemble up to 24 hours early. Cover and refrigerate. Add 10 minutes to bake time.
• For gluten-free, use gluten-free lasagna noodles and flour.
• Spice it up. Add red pepper flakes for heat or diced bell peppers for crunch.
• Avoid overcooking seafood. It toughens quickly. Cook just until done in the skillet.

Variations

These changes keep the dish versatile for diets.

• Shrimp-Only Lasagna: Use all shrimp for simplicity. Double the amount.
• Creamy Lobster Twist: Swap crab for lobster chunks. Luxurious upgrade.
• Vegetarian Version: Replace seafood with mushrooms, zucchini, and artichokes.
• Spicy Cajun Style: Mix in Cajun seasoning and andouille sausage bits.
• Lightened Up: Use low-fat ricotta and milk. Skip wine for broth.
