How to Make Seafood Gratin
Prepare Seafood: Begin by gathering fresh or thawed shrimp and scallops. Rinse them under cold water, then pat them dry with a paper towel for even cooking.
Saut Aromatics: In a large skillet, melt butter over medium heat. Add chopped onion and minced garlic; saut for 3-4 minutes until the onion becomes translucent and fragrant, enhancing the base flavors.
Cook Seafood: Gently add the shrimp and scallops to the skillet. Cook for about 3 minutes, stirring occasionally, until the shrimp turns pink and the scallops are opaque, ensuring lovely tenderness.
Simmer Sauce: Pour in white grape juice and allow it to simmer for 2 minutes. This step enriches the sauce, infusing it with delightful sweetness and depth.
Create Creamy Mixture: Stir in the heavy cream along with salt and black pepper. Mix well until the sauce is uniform and creamy, ready to envelop the seafood in comfort.
Transfer to Baking Dish: Carefully pour the seafood mixture into a baking dish, spreading it evenly. Generously sprinkle grated cheese on top for that ultimate gooey finish.
Bake to Perfection: Preheat the oven to 180 °C (350 °F). Place your baking dish in the oven and bake for about 15 minutes, or until the cheese is bubbly and golden brown just the sight of it will make your mouth water!
Let it Rest: Once out of the oven, allow the gratin to cool slightly for a few minutes before serving. This resting time helps the flavors to settle, making each bite even better!
Optional: Garnish with fresh herbs, like parsley or dill, for a pop of color and flavor.
