Instructions
- 1
Prepare the béchamel: Melt the butter in a small saucepan over medium heat. Whisk in the flour and cook for 1 minute to make a roux. Gradually whisk in the milk, cooking until the sauce is thick and smooth. Remove from heat and stir in a pinch of nutmeg, salt, and pepper.
- 2
Preheat the oven's broiler. Place the sourdough slices on a baking sheet and lightly toast them under the broiler for 1 minute per side.
- 3
Spread a thin layer of Dijon mustard on one slice of the toasted bread. Top with the sliced ham and half of the grated Gruyère cheese.
- 4
Place the second slice of bread on top. Spoon a generous amount of the warm béchamel sauce over the top of the sandwich, spreading it to the edges.
- 5
Sprinkle the remaining grated Gruyère cheese evenly over the béchamel sauce.
- 6
Place the sandwich under the broiler for 3-5 minutes, watching very closely, until the cheese topping is bubbling, melted, and beautifully browned. Serve hot.
