Béchamel Sauce Preparation
- Melt 2 tablespoons of unsalted butter over medium heat in a medium saucepan. Whisk in 2 tablespoons of all-purpose flour to create a roux. Gradually stir in 1 cup of whole milk, whisking until thickened, about 5-7 minutes. Add a pinch of nutmeg and season with salt and pepper before setting aside.
- Take two slices of crusty bread, spread Dijon mustard on one side if desired, then layer with ham and gruyère cheese. Pour béchamel sauce over the sandwich.
- Heat a skillet over medium heat with a tablespoon of butter. Add the sandwich and cook for 3-4 minutes on each side until golden brown and the cheese is melty.
- Preheat broiler. Transfer the sandwich to a baking sheet and broil for 2-3 minutes until the béchamel is bubbly and golden.
- Slice the sandwich diagonally and serve hot, preferably with a green salad or tomato soup.
