Oysters Gratin for Christmas: A Savory and Cheesy Delight

Instructions:

1. Prepare the oysters: Preheat the oven to 190°C (375°F). Place the oysters on a baking tray lined with coarse salt to keep them stable.

2. Prepare the gratin sauce: In a small saucepan, melt the butter over medium heat. Add the Dijon mustard and white wine. Stir in the cream and let simmer for 3-4 minutes. Season with salt, pepper, and add the lemon zest.

3. Assemble the oysters: Spoon the creamy sauce over each oyster. Sprinkle with Parmesan cheese and breadcrumbs. Place the oysters in the oven for about 10 minutes, or until the gratin is golden and bubbling.

4. Serve and garnish: Sprinkle with fresh parsley before serving, accompanied by lemon wedges.
