Step-by-Step Instructions

Step 1: Make the Béchamel Sauce

1. In a small saucepan, melt the butter over medium heat.
2. Whisk in the flour and cook for 1–2 minutes , stirring constantly, until the mixture forms a paste (this is called a roux).
3. Gradually whisk in the warm milk, ensuring no lumps form. Cook, stirring constantly, until the sauce thickens (about 5–7 minutes ).
4. Stir in the nutmeg, salt, and pepper. Remove from heat and set aside.

Step 2: Assemble the Sandwiches

1. Preheat your oven’s broiler and line a baking sheet with parchment paper or foil.
2. Spread one side of each slice of bread with softened butter. Place the slices butter-side down on your work surface.
3. Spread Dijon mustard evenly on the unbuttered side of 4 slices of bread.
4. Layer 2 slices of ham on top of the mustard-coated bread. Sprinkle 1/4 cup of grated Gruyère over the ham.
5. Top each sandwich with the remaining slices of bread (butter-side up).

Step 3: Add the Béchamel & Broil

1. Spread a generous layer of béchamel sauce over the tops of the sandwiches, covering them completely.
2. Sprinkle the remaining Gruyère cheese evenly over the béchamel.
3. Place the sandwiches on the prepared baking sheet and broil for 3–5 minutes , or until the cheese is melted, bubbly, and golden brown. Watch closely to avoid burning.

Step 4: Serve

1. Let the sandwiches cool slightly before slicing in half diagonally.
2. Serve hot with a side of pickles, a simple green salad, or tomato soup for a complete meal.

Tips for Success

• Warm the Milk : Heating the milk before adding it to the roux ensures a smooth béchamel without lumps.
• Use Fresh Bread : Crusty bread holds up better under the béchamel and broiler.
• Storage : These sandwiches are best enjoyed fresh but can be reheated in the oven to restore crispiness.
