- 8 ounces lump crab meat, picked over for shells
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- Salt and black pepper to taste
- Juice of 1 lemon
Béchamel Sauce
- 4 tablespoons unsalted butter
- 1/4 cup all-purpose flour
- 4 cups whole milk, warmed
- 1 cup grated Parmesan cheese
- 1/2 teaspoon nutmeg
- Salt and white pepper to taste
Other Layers
- 12-15 lasagna noodles (no-boil or cooked al dente)

- 1 egg
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Pecorino Romano cheese

Step-by-Step Instructions
Prepare this dish in stages. It takes about 1.5 hours total, plus 45 minutes baking time.
Step 1: Cook the Seafood
Heat olive oil in a large skillet over medium-high heat. Add minced garlic and sauté for 1 minute until fragrant. Do not let it brown.
Add shrimp and scallops. Season with salt, pepper, and lemon juice. Cook for 3-4 minutes, stirring occasionally, until shrimp turn pink and scallops are opaque. Stir in crab meat gently to avoid breaking it up. Remove from heat and set aside to cool. This step builds bold seafood flavor.
Step 2: Make the Béchamel Sauce
Melt butter in a saucepan over medium heat. Whisk in flour to form a roux. Cook for 2 minutes, stirring constantly.
Slowly pour in warmed milk while whisking vigorously. This prevents lumps. Bring to a simmer and cook for 5-7 minutes until thickened. It should coat the back of a spoon.
Stir in Parmesan, nutmeg, salt, and white pepper. Taste and adjust seasoning. Remove from heat. The sauce adds creaminess that ties the lasagna together.
Step 3: Prepare Ricotta Mixture and Spinach
Wilt spinach in a skillet with a splash of water over medium heat for 2 minutes. Drain well and squeeze out excess moisture. Chop roughly.
Mix ricotta, egg, and a pinch of salt in a bowl. This creates a smooth, spreadable layer.
Step 4: Assemble the Lasagna
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Spread 1 cup béchamel on the bottom. Layer 3-4 lasagna noodles. Add half the ricotta mixture, then half the spinach, and half the seafood. Pour 1 cup béchamel over it. Sprinkle with mozzarella and Pecorino.
Repeat layers: noodles, remaining ricotta, spinach, seafood, béchamel, and cheeses. Top with a final layer of noodles, remaining béchamel, and a generous cheese sprinkle.
Step 5: Bake
Cover with foil and bake for 30 minutes. Remove foil and bake another 15-20 minutes until top is golden and bubbly. Let rest 15 minutes before slicing. Resting helps layers set.
Tips for Success
- Choose high-quality seafood. Fresh shrimp and scallops shine brightest. Frozen works if thawed properly—pat dry to avoid watery lasagna.
- Use no-boil noodles to save time. They absorb sauce during baking for perfect texture.
- Make ahead. Assemble up to 24 hours in advance, cover, and refrigerate. Add 10 minutes to bake time.
- Avoid overcooking seafood. It continues cooking in the oven, so pull it from the skillet just done.
- For a spicy twist, add red pepper flakes to the seafood mix. Pair with garlic bread and crisp white wine like Sauvignon Blanc.
Variations
- Lighter Version: Swap full-fat ricotta for low-fat. Use skim milk in béchamel. Reduce cheese on top.
- Luxury Upgrade: Add lobster meat or langoustines. Drizzle with truffle oil before serving.
- Vegetarian Twist: Replace seafood with mushrooms, zucchini, and artichokes. Keep the béchamel for creaminess.
- Gluten-Free: Use gluten-free lasagna noodles and flour blend for roux.
These changes keep the dish versatile for different diets.
