Description

A comforting seafood dish featuring a mix of shrimp, scallops, and white fish baked in a creamy sauce and topped with a crispy breadcrumb layer.


Ingredients

  • 400 g Mixed Seafood (shrimp, scallops, white fish fillets, fresh or frozen, thawed and patted dry)
  • 2 tablespoons Olive Oil
  • 1 small Onion (finely chopped)
  • 2 cloves Garlic (minced)
  • 200 ml Heavy Cream (or coconut milk for dairy-free option)
  • 100 ml Milk
  • 50 g Butter
  • 2 tablespoons All-Purpose Flour
  • 100 g Grated Cheese (Gruyère or cheddar)
  • 50 g Breadcrumbs (mix with melted butter for extra crunch)
  • Salt and Pepper (to taste)
  • Fresh Parsley (for garnish)


Instructions

  1. Preheat the oven to 375°F (190°C).
  2. Heat olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, cooking until softened and fragrant.
  3. Incorporate the mixed seafood into the skillet, seasoning with salt and pepper. Sauté until just cooked through, then remove from heat.
  4. In another saucepan, melt the butter over medium heat. Once melted, whisk in the all-purpose flour and cook for about 2 minutes, stirring constantly to avoid browning.
  5. Slowly pour in the heavy cream and milk, whisking continuously. Cook until the sauce thickens, about 5-7 minutes.
  6. Stir in the grated cheese until fully melted and combined.
  7. Combine the seafood mixture and the sauce in a large bowl, mixing well.
  8. Pour the mixture into a baking dish. Prepare the breadcrumb topping by mixing breadcrumbs with melted butter, then sprinkle generously over the seafood mixture.
  9. Bake in the preheated oven for 20-25 minutes, or until the top is golden and crispy.
  10. Garnish with fresh parsley before serving.

Notes

Using fresh ingredients greatly enhances flavor. Experiment with different cheeses for variety, and don’t rush the preparation steps.
