Béchamel Sauce
- 2.5 tbsp butter
- 2.5 tbsp flour
- 1 1/3 cup milk (warmed)
- 1/8 tsp nutmeg
- 1/4 tsp white pepper
- 1 tsp dijon mustard
- 2 tbsp chives (finely chopped)
- salt (to taste)
Sandwich
- 8 slices brioche bread (thick cut)
- 8 slices ham
- 8 oz gruyère (shredded)
- 4 oz parmigiano reggiano (grated)
- Make the Béchamel: Melt butter in a small saucepan over medium-low heat. Whisk in flour and cook for about 4 minutes to remove the raw flour taste. Slowly whisk in warmed milk and let the sauce thicken, approximately 5 minutes. Stir in nutmeg, white pepper, Dijon mustard, finely chopped chives, and salt to taste. Remove from heat.
- Assemble the Sandwiches: Preheat oven to 400°F (205°C) and line a baking sheet with parchment paper. Place 4 slices of brioche on the baking sheet and spread béchamel sauce evenly over the tops. Layer ham slices and about 1 oz shredded Gruyère on each. Spread béchamel on one side of the remaining 4 brioche slices and place those sauce-side down on top of each sandwich. Finish by topping each sandwich with the remaining shredded Gruyère and freshly grated Parmigiano Reggiano.
- Bake and Broil: Bake sandwiches in the preheated oven for 12-15 minutes until heated through and cheese starts to melt. Then switch to broil for 1-2 minutes until the cheese topping is bubbling and golden brown. Serve immediately while hot and gooey.
Notes
- Use thick-cut brioche for the best texture and flavor.
- Be careful not to burn the béchamel when cooking the roux; cook on medium-low heat.
- Broiling time is quick; watch carefully to avoid burning the cheese.
- You can substitute Gruyère with Emmental cheese if unavailable.
- For a lighter version, use turkey ham and low-fat milk.
