Ingredients

• 2 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 1 cup Whole milk
• 0.5 teaspoons Salt
• 0.25 teaspoons Black pepper
• 0.125 teaspoons Nutmeg
• 1 cup Gruyère cheese, shredded
• 2 tablespoons Parmesan cheese, grated
• 4 slices Bread slices (such as sourdough or white sandwich bread)
• 2 teaspoons Dijon mustard
• 4 slices Ham slices
• 4 slices Tomato slices
• 2 tablespoons Olive oil or melted butter (for toasting)

Directions

Step 1

Preheat your oven's broiler and line a baking sheet with parchment paper.

Step 2

In a small saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in the all-purpose flour to form a roux and cook for 1 minute, whisking constantly.

Step 3

Gradually pour in the milk while whisking, ensuring no lumps form. Continue cooking until the béchamel sauce thickens, about 2-3 minutes.

Step 4

Season the sauce with salt, pepper, and nutmeg. Remove from the heat and stir in 1/2 cup of the shredded Gruyère cheese and all the Parmesan cheese until melted and smooth.

Step 5

Spread a thin layer of Dijon mustard on one side of each bread slice.

Step 6

On two slices of bread, layer 2 slices of ham and 2 slices of tomato. Spoon a generous layer of the béchamel sauce over the tomatoes, then sprinkle with a bit of the remaining Gruyère cheese.

Step 7

Top each sandwich with the other bread slices, mustard side down.

Step 8

Brush the outside of each sandwich with olive oil or melted butter.

Step 9

Heat a skillet or griddle over medium heat. Toast each sandwich for 2-3 minutes per side, or until golden brown and crispy.

Step 10

Transfer the sandwiches to the prepared baking sheet. Spoon the remaining béchamel sauce on top of each sandwich, spreading it evenly across the surface.

Step 11

Sprinkle the remaining Gruyère cheese on top and place the sandwiches under the broiler. Broil for 2-3 minutes, or until the cheese is bubbly and lightly browned.

Step 12

Carefully remove the sandwiches from the oven and let them cool for 1-2 minutes before serving.
