Ingredients

• 2 tablespoons Unsalted butter
• 1 tablespoon All-purpose flour
• 0.75 cup Whole milk
• 1 teaspoon Dijon mustard
• 0.25 teaspoon Salt
• 0.25 teaspoon Ground black pepper
• 0.125 teaspoon Freshly grated nutmeg
• 0.33 cup Crumbled blue cheese
• 0.5 cup Gruyère cheese, shredded
• 4 slices Thick-cut sandwich bread
• 4 slices Thinly sliced ham
• 2 teaspoons Olive oil

Directions

Step 1

In a small saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for 1 minute to form a roux.

Step 2

Slowly whisk in the milk, ensuring there are no lumps. Cook for 2-3 minutes, stirring continuously, until the mixture thickens.

Step 3

Add the Dijon mustard, salt, pepper, and nutmeg to the béchamel sauce. Stir well to combine.

Step 4

Remove the saucepan from heat and mix in the crumbled blue cheese. Stir until the cheese is fully melted and incorporated into the sauce. Set aside to cool slightly.

Step 5

Preheat a large skillet or griddle over medium heat.

Step 6

Lay out the bread slices. Spread a thin layer of the blue cheese béchamel on each slice. Reserve some of the béchamel for topping.

Step 7

On two slices of bread, layer the ham and a portion of the shredded Gruyère cheese. Top with the remaining bread slices, béchamel side down, to form two sandwiches.

Step 8

Brush the outsides of each sandwich with olive oil to help with browning.

Step 9

Place the sandwiches on the hot skillet. Cook for 2-3 minutes per side, pressing gently with a spatula, until the bread is golden brown and crispy.

Step 10

Preheat your broiler. Transfer the grilled sandwiches to a baking sheet lined with parchment paper.

Step 11

Spread the remaining béchamel sauce on top of each sandwich and sprinkle the remaining Gruyère cheese over the sauce.

Step 12

Broil the sandwiches for 3-4 minutes, until the cheese topping is bubbly and lightly golden.

Step 13

Remove from the oven, let cool for a minute or two, and serve immediately.
