How to Make Creamy Seafood Gratin
  1. Prepare the Seafood: If using frozen seafood, thaw completely and pat dry. Chop shrimp and scallops into bite-sized pieces.
  2. Sauté the Aromatics: Heat olive oil in a large skillet over medium heat. Add diced onions and sauté until translucent (5-7 minutes). Add minced garlic and cook for an additional minute.
  3. Deglaze and Cook the Seafood: Pour in dry white wine, simmer for 2-3 minutes. Add the seafood, cooking until just done (5-7 minutes). Discard any unopened mussels or clams.
  4. Make the Béchamel Sauce: Melt butter in a saucepan. Whisk in flour to create a roux. Gradually add milk, whisking until thickened (5-7 minutes). Stir in cream, cheeses, and nutmeg until creamy.
  5. Combine and Season: Gently fold the seafood mixture into the béchamel. Stir in lemon zest, parsley, and season with salt and pepper.
  6. Prepare for Baking: Preheat oven to 375°F (190°C). Grease a baking dish and pour in the seafood mixture, spreading evenly.
  7. Add the Crunchy Topping: Combine breadcrumbs with extra cheese, sprinkle over the gratin for a crispy crust.
  8. Bake to Perfection: Bake for 20-25 minutes until bubbly and golden brown. Let rest for a few minutes before serving.
