Croque Monsieur Ham and Cheese Sandwich

Ingredients

• 2 slices of white bread
• 2 slices of ham
• 2 slices of Swiss cheese
• 1 tablespoon butter
• 1 tablespoon all-purpose flour
• 1 cup milk
• Salt and pepper to taste
• 1 teaspoon Dijon mustard, optional

Directions

1. Heat the oven to 350 degrees F (175 degrees C).
2. If you’re using the Dijon mustard, spread it onto one side of each bread slice. Layer the Swiss cheese and ham over one slice, then close the sandwich with the second slice, placing the mustard side facing in.
3. Set a small saucepan over medium heat and melt the butter. Stir in the flour until the mixture comes together and begins to bubble. Pour in the milk slowly, stirring the whole time, and cook until the sauce thickens. Add salt and pepper to taste.
4. Spoon the white sauce over the sandwich, then transfer it to the heated oven. Bake for 15 minutes, or until the cheese has melted and the top is golden brown. Serve hot.
