グラタンオイスターモルネー

Instructions:

1. 
   1 Preparation

   • Preheat your oven to 200°C. Carefully clean the oysters and ensure any debris is removed.
2. 
   2 Forming the Roux

   • In a saucepan over medium heat, melt the butter. Add the flour and whisk continuously until it turns a light, golden hue.
3. 
   3 Creating the Mornay Sauce

   • Slowly incorporate the milk into the roux while stirring steadily to avoid lumps. Allow the mixture to thicken, then blend in the grated Gruyere. Season with salt, white pepper, and a pinch of nutmeg.
4. 
   4 Assembling the Dish

   • Place the cleaned oysters in a single layer in a baking dish. Evenly drizzle the creamy sauce over them and sprinkle dry breadcrumbs across the top for added texture.
5. 
   5 Baking

   • Bake the assembled dish in the preheated oven for 12-15 minutes, or until the sauce bubbles and the top develops a crisp, golden finish.
6. 
   6 Final Touches

   • Once out of the oven, allow the dish to settle briefly before serving. Garnish with lemon wedges to add a bright, zesty contrast.
