Ingredients

Preparation

  1. Preheat oven to 190°C (375°F). If using regular lasagna noodles, cook them according to package directions until al dente. Drain and set aside.
  2. Prepare the béchamel sauce: In a large saucepan, melt 60g butter over medium heat. Add the flour and whisk constantly for 1-2 minutes to create a roux. Gradually pour in the milk, whisking continuously to prevent lumps. Bring to a simmer, then reduce heat and cook, stirring, until the sauce thickens (about 5-7 minutes). Season with salt, pepper, and a pinch of nutmeg. Set aside.
  3. In a separate pan, melt 15g butter over medium heat. Add the chopped onion and sauté until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.
  4. Add the shrimp to the pan with onion and garlic. Cook for 2-3 minutes until they just turn pink. Stir in the crab meat and fresh spinach. Cook until spinach wilts, then remove from heat. Season with salt and pepper.
  5. To assemble the lasagna: Spread a thin layer of béchamel sauce on the bottom of a 9x13 inch baking dish. Arrange a layer of lasagna noodles over the sauce.
  6. Spread half of the seafood mixture over the noodles. Top with a layer of béchamel sauce, then sprinkle with a third of the shredded mozzarella and a third of the grated Parmesan.
  7. Repeat with another layer of noodles, the remaining seafood mixture, more béchamel, and another third of the mozzarella and Parmesan.
  8. Place the final layer of noodles, cover with the remaining béchamel sauce, and sprinkle generously with the remaining mozzarella and Parmesan cheese.
  9. Bake for 30-35 minutes, or until the top is golden brown and bubbly. If the top browns too quickly, you can cover it loosely with foil.
  10. Remove from oven and let rest for 10-15 minutes before slicing and serving. Garnish with fresh chopped parsley.
