  • 4 Slices Rustic Bread Sourdough or Brioche
  • 4 slices Ham thick
  • 1,5 cup Gruyere Cheese shredded
  • 2 tbsp Dijon Mustard

Bechamel Sauce

  • 1 tbsp Butter unsalted
  • 1 tbsp Flour all-purpose
  • 1 cup Milk
  • Salt & Pepper to taste
  • Pinch of fresh Nutmeg


  • Heat up your milk either in a saucepan or microwave but make sure it is not boiling.
  • In a frying pan, melt the butter. Once melted, add flour and whisk well. Start adding warm milk gradually until all milk is incorporated and the sauce is smooth and thick.
  • Season the sauce with salt, pepper, and nutmeg. Set aside.
  • Lightly toast your bread for a few minutes in a toaster oven. Once toasted spread mustard on one slice of the bread and add ham and cheese on the other slice. Put the slices together and repeat with the remaining bread.
  • Spread about 2 tablespoons of the béchamel sauce on top of each sandwich, add a little bit more shredded cheese and place in the toaster oven for few minutes until the cheese starts to melt.
  • Change the settings to broiler and broil the sandwich until the sauce is bubbly and golden (for about 30 seconds). Remove from the toaster and cut in half. Enjoy.


If you don't have a toaster oven, you can toast your bread on each side in a frying pan with a tablespoon of butter. Once your sandwich is assembled you can bake it in the oven. Heat up your oven to 400F and place the sandwich there for a few minutes until the cheese melts. Change the settings to broil and broil your sandwich for about 30 seconds.
** It is best to use thick sliced ham (like one from Easter leftovers), but if you have thinly sliced deli ham, use at least 4 slices per sandwich.
