Ingredients

• 12 pieces Fresh oysters on the half shell
• 2 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 1 cup Whole milk
• 1 cup Heavy cream
• 1 cup Gruyère cheese, grated
• 1 4 cup Parmesan cheese, grated
• 2 tablespoons Dry white wine
• 0.125 teaspoons Ground nutmeg
• 0.25 teaspoons Salt
• 0.25 teaspoons Black pepper
• 0.25 cup Breadcrumbs
• 2 tablespoons Fresh parsley, finely chopped (for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Line a baking tray with rock salt or balled-up aluminum foil to hold the oysters steady during baking.

Step 2

Ensure oysters are clean and properly shucked, leaving each oyster in its half shell. Arrange the oysters on the prepared baking tray.

Step 3

In a medium saucepan, melt the butter over medium heat. Add the flour and whisk constantly for 2 minutes to form a roux.

Step 4

Gradually whisk in the milk and cream. Continue to cook, stirring constantly, until the mixture thickens and bubbles gently, around 4–5 minutes.

Step 5

Reduce the heat to low. Stir in the grated Gruyère cheese and 2 tablespoons of Parmesan cheese until melted and well combined.

Step 6

Stir in the white wine, nutmeg, salt, and black pepper. Remove the Mornay sauce from the heat and set aside.

Step 7

Spoon about 1-2 tablespoons of the Mornay sauce over each oyster, making sure the sauce completely covers the oyster.

Step 8

Sprinkle the breadcrumbs and the remaining Parmesan cheese evenly over the sauced oysters.

Step 9

Place the tray in the oven and bake for 10–12 minutes, or until the sauce is bubbly and the top is golden brown.

Step 10

Remove from the oven and let cool slightly. Garnish with chopped parsley before serving. Serve warm as an elegant appetizer or main dish.
