- 1 pound (450g) elbow macaroni
- Water for boiling, plus salt
- 6 tablespoons (85g) unsalted butter
- 1/4 cup (30g) all-purpose flour
- 3 cups (710ml) whole milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional, but recommended!)
- 12 ounces (340g) sharp cheddar cheese, shredded

Instructions:
- Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish.
- Cook macaroni according to package directions until al dente. Drain well.
- In a large saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes, stirring constantly, until pale golden brown (this is the roux!).

- Remove from heat. Stir in salt, pepper, and nutmeg. Add cheddar and Gruyere cheese, stirring until melted and smooth.
- Add drained macaroni to the cheese sauce and stir to coat evenly. Pour into the prepared baking dish.
