Ingredients

• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 2 cups whole milk
• 1.5 cups grated Gruyère cheese
• 0.5 cups grated Parmesan cheese
• 0.25 teaspoons salt
• 0.25 teaspoons ground white pepper
• 0.125 teaspoons ground nutmeg (optional)

Directions

Step 1

Melt the unsalted butter in a medium saucepan over medium heat.

Step 2

Whisk in the all-purpose flour and cook, stirring constantly, for 1–2 minutes to create a smooth roux. Avoid browning the flour.

Step 3

Gradually pour in the whole milk while continuously whisking to prevent lumps. Cook the mixture, still whisking, until it thickens and begins to bubble gently, about 5–7 minutes.

Step 4

Reduce the heat to low and stir in the grated Gruyère cheese and grated Parmesan cheese, one handful at a time, allowing each addition to melt completely before adding the next.

Step 5

Season the sauce with salt, ground white pepper, and ground nutmeg, if desired. Taste and adjust the seasoning as needed.

Step 6

Remove the sauce from the heat and serve immediately. If not using right away, cover with plastic wrap to prevent a skin from forming on the surface.
