Ingredients
  

8 slices of sourdough bread

6 oz (170g) ham, thinly sliced

6 oz (170g) Gruyère cheese, grated

2 tablespoons Dijon mustard

4 tablespoons unsalted butter, softened

1/2 cup milk

1/4 cup all-purpose flour

1/4 teaspoon nutmeg

Salt and pepper, to taste

2 tablespoons freshly chopped chives (for garnish)

Instructions
 

Make the Béchamel: In a medium saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in the flour and cook for about 2 minutes until golden, forming a roux.

    Gradually whisk in the milk, stirring constantly to avoid lumps. Continue to cook until the sauce thickens, about 5-7 minutes.

      Stir in the nutmeg, and season with salt and pepper. Remove from heat and set aside.

        Prepare the Bread: Preheat your oven to 400°F (200°C). Lay out four slices of sourdough bread. Spread Dijon mustard evenly over each slice.

          Layer the Ingredients: Top each slice with a layer of ham, followed by a generous sprinkle of grated Gruyère cheese. Place the other four slices of sourdough on top to create sandwiches.

            Butter and Grill: Spread the remaining butter on the outside of each sandwich. In a skillet over medium heat, grill the sandwiches for 3-4 minutes per side, until golden and crispy.

              Assemble for Baking: Place the grilled sandwiches on a baking sheet. Pour the prepared béchamel sauce generously over each sandwich, and top with any remaining Gruyère cheese.

                Bake: Bake in the preheated oven for 10-12 minutes until the cheese is bubbly and golden.

                  Garnish and Serve: Remove from the oven, let cool slightly, then sprinkle with freshly chopped chives before slicing each sandwich in half.
