Step By Step How to Make Croque Monsieur

Making the Béchamel Sauce

In a small saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until lightly golden, forming a roux. Gradually whisk in the milk, continuing to whisk until the sauce thickens, about 3-5 minutes. Add salt, pepper, and nutmeg. Remove from heat and set aside.

Assembling the Sandwich

Preheat your oven to 375°F (190°C). Lightly toast the bread slices in a toaster or under a broiler until just golden. Spread Dijon mustard on one side of each slice of toasted bread. On four slices of bread, place a slice of ham, then sprinkle with grated Gruyère cheese. Top with another slice of bread, mustard side down, to form a sandwich.

Place the sandwiches on a baking sheet. Spoon the béchamel sauce over the top of each sandwich, spreading it to cover the entire surface. Sprinkle with additional grated Gruyère and Parmesan cheese if desired.


Bake the sandwiches in the preheated oven for about 10-15 minutes, or until the cheese on top is melted and golden brown.


Serve the Croque Monsieur hot, optionally garnished with a sprinkle of fresh parsley if desired.

Tips To Make Croque Monsieur

Use high-quality, thick-cut bread for a sturdier sandwich. Gruyère is traditional, but Emmental or Swiss cheese are good substitutes.

Make sure the béchamel sauce is smooth and lump-free. Whisk continuously while adding the milk. Be generous with the béchamel sauce and cheese to ensure a rich and creamy sandwich.
