Ingredients
-
24 oysters (half shell) – Ensure they are fresh and properly shucked.
2 cups milk
1 cup grated Gruyere cheese
2 tablespoons Parmesan cheese
2 teaspoons cornflour
2 tablespoons Parmesan cheese (extra) – For sprinkling on top before grilling.
Rock salt – To stabilize the oysters while grilling.
Directions
Mornay sauce:
In a small saucepan, gently heat the milk over medium heat.
In a separate small bowl, mix the cornflour with a little cold water to create a smooth slurry.
This prevents lumps from forming in the sauce.
Once the milk is hot, slowly pour the cornflour slurry into the milk, whisking constantly. Continue to stir the mixture until it thickens. The sauce should coat the back of a spoon.
Reduce the heat to low. Add the grated Gruyere cheese and the first 2 tablespoons of Parmesan cheese to the sauce. Stir continuously until all the cheese has completely melted and the sauce is smooth and creamy.
Prepare the oysters. Spread a layer of rock salt into the oven-proof dish, enough to cover the bottom completely. The rock salt helps to stabilize the oysters, preventing them from tipping over during cooking and ensuring even heat distribution.
Arrange the oysters in their half shells on top of the rock salt, making sure they are relatively level.
Spoon the mornay sauce generously over each oyster, completely covering the oyster meat.
Sprinkle the remaining 2 tablespoons of Parmesan cheese over the top of each oyster. This will create a golden-brown crust when grilled.
Preheat the grill to high.
Grill the oysters until the cheese is browned, bubbly, and slightly golden, about 5-10 minutes, but keep a close eye on them to prevent burning. The oysters are ready when the sauce is bubbling and the cheese is browned.
