The Perfect Croque Monsieur: A Classic French Sandwich
Get ready to elevate your lunch, brunch, or late-night snack with a truly iconic piece of French cuisine: the Croque Monsieur.
Forget the simple ham and cheese—this is an experience. The Croque Monsieur (which translates to "crunchy, mister") takes humble ingredients and transforms them into a luxurious, satisfying meal. It features perfectly toasted bread, a layer of savory ham, a generous amount of nutty Gruyère cheese, and, most importantly, a blanket of creamy, velvety Béchamel sauce, baked until golden and bubbling.
It’s rich, comforting, and has a textural contrast—the crisp crust and the soft, creamy interior—that is utterly irresistible. This recipe is surprisingly simple to master and will instantly transport you to a Parisian café.
The Secret Weapon: Béchamel Sauce
The Béchamel sauce is what separates a mere grilled cheese from a Croque Monsieur. It is one of the five "mother sauces" of French cuisine and is simply a rich white sauce made from butter, flour (a roux), and milk.
Don't be intimidated! It takes just a few minutes to whisk together and is the key to achieving that creamy, luscious texture that binds the sandwich together.

Instructions
1. Make the Béchamel Sauce
In a small saucepan, melt the 2 tablespoons of butter over medium heat.
Whisk in the flour to create a smooth paste (the roux). Cook for 1 minute, stirring constantly.
Slowly pour in the warm milk, whisking continuously to prevent lumps.
Bring the sauce to a gentle simmer, still whisking, until it thickens to a pourable, creamy consistency (about 3-5 minutes).
Remove from heat and whisk in the Dijon mustard, a pinch of nutmeg, salt, and pepper. Set aside.
2. Prepare the Sandwiches
Preheat your oven's broiler (or an oven to 400°F/200°C).
Lightly butter both sides of all four slices of bread.
Heat a large skillet over medium heat. Toast the bread slices on both sides until golden brown (about 2 minutes per side).
On a baking sheet lined with parchment paper, lay out two slices of the toasted bread.
Spread a thin layer of Béchamel sauce on each of the two slices.
Top the sauce with a quarter cup of Gruyère cheese, followed by two slices of ham.
Place the remaining two slices of toasted bread on top of the ham.
3. Bake and Finish
Generously slather the tops of the assembled sandwiches with the remaining Béchamel sauce, ensuring it covers the entire surface.
Sprinkle the remaining Gruyère cheese over the sauce.
Place the baking sheet in the preheated oven or under the broiler.
If baking (400°F/200°C): Bake for 5-8 minutes, or until the cheese is melted and the sauce is bubbling.
If broiling: Watch constantly! Broil for 2-4 minutes until the cheese is golden brown and caramelized.
Remove from the oven, let rest for 1 minute, and serve immediately.
