Bread and Spread
- 4 slices of sturdy white or sourdough bread
- Butter for toasting (about 2 tbsp)
- Optional: Dijon mustard, a light layer on bread slices
Filling
- 4–6 thin slices of ham
- 1 ½ cups grated Gruyère cheese, divided
Béchamel Sauce
- 2 tbsp butter
- 2 tbsp all-purpose flour
- 1 ½ cups milk
- Pinch of nutmeg
- Salt and white pepper to taste
- Prepare the béchamel sauce: Melt butter in a saucepan over medium heat. Stir in flour to create a smooth paste and cook for about 1 minute. Gradually whisk in milk, continuing to stir until the sauce thickens. Season with salt, white pepper, and a pinch of nutmeg. Remove from heat and set aside.
- Assemble the sandwich: If using, spread a light layer of Dijon mustard on one side of each bread slice. On one slice, layer ham evenly and then generously grate some Gruyère cheese over it. Spoon a portion of béchamel sauce over the cheese, then place the second bread slice on top, mustard side down, creating a neat sandwich stack.
- Cook the sandwich: Heat a skillet over medium heat and melt some butter. Place the sandwich in the skillet and cook until the bottom is golden brown and crispy, about 3-4 minutes. Carefully flip and cook the other side until golden and the cheese begins to melt.
- Add topping and broil: Transfer the sandwich to a baking sheet. Spread more béchamel sauce on top and sprinkle with the remaining Gruyère cheese. Place under a preheated broiler for 2-3 minutes until the cheese is bubbly and perfectly browned. Watch closely to avoid burning.
- Serve immediately: Let the sandwich rest for 1-2 minutes to allow layers to settle and prevent cheese from spilling out. Slice carefully and enjoy warm with gooey cheese and crispy bread.
Notes
- Choose thick, sturdy bread to prevent sogginess and hold fillings securely.
- Do not skimp on Gruyère cheese to maintain the signature creamy, nutty flavor.
- Freshly made béchamel sauce elevates the sandwich far beyond store-bought alternatives.
- Keep a close eye on the broiler to avoid burning the cheese topping.
- Allow the sandwich to rest briefly after cooking for easier slicing and better texture.
