Croque monsieur is a classic French sandwich. This recipe appears in "Martha Stewart's Cooking School."


Yield: 4 sandwiches



  • 1 tablespoon unsalted butter
  • 1 1/2 tablespoons all-purpose flour
  • 1 cup whole milk, heated
  • 1 teaspoon coarse salt
  • 1/2 teaspoon freshly ground black pepper
  • Pinch freshly grated nutmeg
  • 2 cups shredded Gruyere cheese, divided
  • 8 slices toasted or grilled country bread, sliced 1/4 inch thick
  • 4 teaspoons Dijon mustard
  • 1/4 pound sliced baked ham, such as prosciutto cotto or jamon royale
  • Pinch herbes de Provence
  • Cornichons, for serving


  1. Preheat oven to 400 degrees.
  2. Melt butter in a saucepan over medium heat. Add flour and cook, stirring with a wooden spoon for 2 minutes. Increase heat to medium-high, and slowly add hot milk. Cook, whisking constantly, until thickened, 5 to 6 minutes. Remove pan from heat, and add salt, pepper, nutmeg, and 1/2 cup Gruyere. Set bechamel sauce aside.
  3. Lightly brush 4 slices bread with mustard. Divide ham evenly between bread, and sprinkle each with 2 tablespoons Gruyere. Top with 4 more slices toasted bread. Slather tops with the bechamel sauce, and sprinkle with remaining Gruyere and herbes de Provence.
  4. Bake sandwiches until topping is lightly browned, 12 to 15 minutes. Serve hot with cornichons.
