minutesIngredients
0.5 lb shrimp, peeled and deveined
0.5 lb scallops, cleaned
1 cup milk
1 cup heavy cream
2 tablespoons all-purpose flour
3 tablespoons butter
1 cup grated gruyere cheese
0.5 cup breadcrumbs
1 teaspoon salt
0.5 teaspoon black pepper
1 tablespoon lemon juice
2 cloves garlic, minced
1 tablespoon chopped parsley for garnish
Directions
- Preheat your oven to 375 degrees Fahrenheit. Prepare an ovenproof baking dish and set aside for later use.
- Melt the butter in a large pan over medium heat. Add the garlic and sauté for a minute until fragrant.
- Whisk in the flour, stirring constantly to form a smooth paste. Gradually add milk and cream, whisking continuously.
- Continue cooking until the mixture thickens into a creamy sauce, about 5-7 minutes. Stir frequently to prevent lumps.
- Season the sauce with salt, pepper, lemon juice, and half of the grated cheese, mixing until the cheese is melted.
- Gently combine the shrimp and scallops with the sauce. Ensure all seafood is evenly coated with the creamy mixture.
- Transfer the seafood and sauce mixture into the prepared baking dish, spreading it out evenly for even cooking.
- Mix the breadcrumbs with the remaining cheese in a bowl. Sprinkle evenly over the seafood mixture in the dish.
- Bake in the preheated oven for 25-30 minutes until the top is golden and crispy and the seafood is just cooked.
- Garnish the seafood gratin with freshly chopped parsley and let it sit for a few minutes before serving warm.
