🧾 Ingredients

• Scallops: Opt for fresh, high-quality scallops still in their shells for the best presentation and flavor. If fresh isn't available, frozen scallops are a suitable alternative but make sure they are thoroughly defrosted before use. Tip: Save the shells to use in the future with frozen scallops).
• White Wine: Choose a dry white wine like Sauvignon Blanc or Pinot Grigio to complement the delicate flavor of the scallops. Avoid sweet wines as they may overpower the dish.
• Parsley: Fresh parsley adds a vibrant, herby note to the gratin. Finely chop it to evenly distribute the flavor.
• Breadcrumbs: Use fresh or panko breadcrumbs for a crisp, golden topping. You can also used toasted Pangrattato for extra flavor.
• Olive Oil: A drizzle of high-quality olive oil helps bind the breadcrumb mixture and adds a subtle richness to the dish.
• Garlic: Finely minced garlic provides a savory depth to the gratin. Adjust the amount to suit your taste.
• Lemon: A squeeze of fresh lemon juice and lemon zest brightens the flavors and balances the richness of the butter and olive oil.
• Butter: Use unsalted butter to control the seasoning.

❄️ Storage & Reheating

• Fridge: Leftover Scallops Gratin can be stored in an airtight container in the refrigerator for up to 2 days. Allow the dish to cool completely before storing to maintain the texture of the topping.
• Freezer: Freezing is not recommended for cooked scallops as they can become rubbery when reheated. However, you can prepare the gratin topping and freeze it separately for future use.
• Reheating: To reheat, preheat your oven to 350°F (175°C). Place the scallops in an oven-safe dish, cover loosely with foil to prevent the topping from burning, and heat for about 10 minutes or until warmed through. Avoid using a microwave, as it may overcook the scallops and make them chewy.
