Croque Monsieur is a classic French sandwich that consists of ham and cheese, typically Gruyère or Emmental, (I use Emmental here) sandwiched between slices of bread. The sandwich is toasted or grilled until the cheese achieves a melted, bubbly state, and the bread attains a crispy, golden-brown texture. It’s a popular choice for a quick and satisfying meal or snack. Occasionally, the top slice of bread is also generously spread with béchamel sauce before grilling, adding an extra layer of richness to the sandwich.

Béchamel Sauce 1. Melt butter in a saucepan over medium heat. Add in flour, cook and stir constantly then add milk, stir until well combined. 2. Once the sauce thickens, add dijon mustard, nutmeg powder, salt, and black pepper, stir until well combined then turn off the heat.

Sandwich 1. Preheat oven to 425℉ or 218℃. Line a baking tray with parchment paper. 2. Place 2 white bread on baking tray, spread the béchamel sauce all over the top of each bread then top it with turkey breast slices, and sprinkle it with emmental cheese and parmesan cheese. 3. Place remaining slice of bread on top and spread it with béchamel sauce, emmental cheese, and parmesan cheese. 4. Bake for about 5 minutes or until the cheese is melted and lightly golden.
