Indulge in the rich flavors of a luxurious seafood gratin, a dish that combines the freshness of the ocean with creamy, cheesy goodness. Perfect for special occasions or a sophisticated dinner, this gratin features a decadent Béchamel sauce infused with Gruyère cheese and a medley of fresh seafood.
Ingredients
- 200g mixed seafood (shrimp, scallops, crab)
- 2 tablespoons olive oil
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 500ml milk
- 50g unsalted butter
- 50g all-purpose flour
- 150g Gruyère cheese, grated
- Salt and pepper to taste
- Fresh parsley for garnish
Preparation Steps
Start by preheating your oven to 200°C (390°F). In a skillet, heat the olive oil over medium heat. Add the chopped onion and garlic, sautéing until translucent and fragrant. Add the mixed seafood and cook for about 3-4 minutes until just cooked through. Remove from heat and set aside.
Meanwhile, prepare the Béchamel sauce. In a saucepan, melt the butter over low heat. Whisk in the flour and cook for 1-2 minutes to form a roux. Gradually add the milk, whisking constantly to prevent lumps. Continue stirring until the sauce thickens, about 5 minutes. Remove from heat and stir in two-thirds of the grated Gruyère cheese. Season with salt and pepper.
Combine the cooked seafood with the Béchamel sauce. Mix well and transfer the mixture into a buttered baking dish. Sprinkle the remaining Gruyère cheese evenly on top.
Place the dish in the oven and bake for 20-25 minutes, or until the top is golden and bubbling. Garnish with fresh parsley before serving.
