Step 1
Preheat the oven to 400F. Brush the inside of a large soufflé dish with 2 tablespoons of softened butter. Sprinkle the Parmesan onto the buttered surface of the dish and gently shake the dish to spread the cheese evenly up the sides.
Step 2
In a large saucepan set over medium heat, melt 4 tablespoons of butter. Whisk the flour into the melted butter, and cook, stirring constantly, for 1 minute. Slowly stir the milk into the butter mixture, and cook, stirring constantly, until it thickens.
Step 3
Remove the milk from the heat and stir in the salt, pepper, nutmeg, egg yolks, and cheese. In a separate clean, dry bowl, beat the egg whites and cream of tartar until the egg white form stiff peaks. Stir a few spoons of the egg whites into the cheese mixture and then gently fold the remaining egg whites into the soufflé batter.
Step 4
Pour the batter into the prepared soufflé dish and bake it for 25 to 30 minutes, or until the soufflé is puffed and deep golden brown. Serve the cheese soufflé immediately.
Step 5
This cheese soufflé recipe makes 6 to 8 servings.
