Ina Garten’s Seafood Gratin is a classic French-inspired baked seafood casserole. It features shrimp, scallops, and sometimes lobster or white fish, all nestled in a luscious white wine cream sauce and topped with cheesy, herbed breadcrumbs. The dish is then baked until golden and bubbling, resulting in a luxurious mix of tender seafood and crispy, savoury topping.

Ingredients

Scale

  • 1/2 pound large shrimp, peeled and deveined

  • 1/2 pound sea scallops, tough muscle removed

  • 1/2 pound firm white fish (like cod or halibut), cut into chunks

  • 4 tablespoons unsalted butter

  • 2 tablespoons olive oil

  • 1 cup leeks, white and light green parts, sliced

  • 1 tablespoon garlic, minced

  • 1/3 cup all-purpose flour

  • 1/2 cup dry white wine

  • 1 1/2 cups seafood stock (or fish/chicken stock)

  • 1 cup heavy cream

  • 1 teaspoon kosher salt

  • 1/2 teaspoon black pepper

  • 2 tablespoons fresh parsley, chopped

  • 1 teaspoon lemon zest

  • 1/2 cup grated Gruyère or Parmesan cheese

  • 1 cup panko breadcrumbs

  • 2 tablespoons butter (melted for topping)

Instructions

  • Preheat the oven to 375°F (190°C) and butter a medium-sized gratin dish or baking dish.

  • Sauté the leeks and garlic – In a large skillet, melt butter with olive oil over medium heat. Add leeks and cook for 5–7 minutes until soft, then stir in garlic and cook for 1 minute.

  • Make the sauce – Sprinkle in the flour and cook, stirring constantly, for about 2 minutes. Pour in the white wine and cook for another minute. Add seafood stock and bring to a simmer, then stir in the cream, salt, and pepper. Cook until thickened, about 5 minutes.

  • Add seafood – Fold the shrimp, scallops, and fish into the sauce and cook gently for 2–3 minutes just to begin firming up. Remove from heat and stir in parsley and lemon zest.

  • Transfer to baking dish – Pour the mixture into the prepared gratin dish and spread evenly.

  • Prepare the topping – In a small bowl, mix breadcrumbs, grated cheese, and melted butter. Sprinkle evenly over the seafood mixture.

  • Bake until golden – Place in the oven and bake uncovered for 20–25 minutes, or until bubbling and the top is crisp and golden.

  • Rest before serving – Let it sit for 5 minutes to settle, then serve warm with a wedge of lemon or fresh herbs.
