How to Make Seafood Gratin
Ingredients You’ll Need
200 g Shrimp (Peeled and deveined.)
200 g Scallops (Fresh or thawed if frozen.)
2 tablespoons Butter (For sautéing.)
1 medium Onion (Chopped.)
2 cloves Garlic (Minced.)
200 ml Heavy cream (For the creamy sauce.)

Step-by-Step Directions
Gather fresh shrimp and scallops. If using frozen seafood, thaw completely, rinse under cold water, and pat dry. In a large skillet, melt butter over medium heat. Add chopped onion and minced garlic, sauté for 3-4 minutes until translucent. Add shrimp and scallops to the skillet, cooking for about 3 minutes until shrimp turns pink and scallops are opaque. Pour in white grape juice and simmer for 2 minutes. Stir in heavy cream, salt, and black pepper, mixing well. Transfer the seafood mixture into a baking dish and sprinkle grated cheese on top. Preheat the oven to 180°C (350°F). Bake the gratin for about 15 minutes until the cheese is bubbly and golden brown. Remove from the oven and let cool slightly before serving.
How to Serve Seafood Gratin
Serve seafood gratin hot from the oven. It pairs well with a fresh green salad and some crusty bread for dipping. You can also add a squeeze of lemon juice on top for an extra burst of flavor. This dish makes a great main course and can be complemented by side dishes like steamed vegetables or rice.
How to Store Seafood Gratin
If you have leftovers, let the gratin cool completely. Store it in an airtight container in the refrigerator for up to 2 days. To reheat, place it in the oven at 180°C (350°F) until warmed through. Avoid reheating in the microwave to keep the texture creamy and avoid excess moisture.
Tips for the Best Seafood Gratin

Be careful not to overcook the seafood, as it can become tough. Also, feel free to mix in some sautéed vegetables like spinach or mushrooms for extra taste and nutrition.
