What Exactly *Is* a Croque Monsieur?

Before we dive into the recipes, let’s clarify what defines a Croque Monsieur. At its heart, it’s a baked or fried sandwich made with ham and cheese. However, the defining characteristic that sets it apart is the béchamel sauce, a creamy white sauce that adds richness and depth. The sandwich is often topped with grated cheese, which melts and browns under the heat, creating a delightful crust.

The Classic Croque Monsieur Recipe: A Step-by-Step Guide

This recipe is the foundation upon which all other variations are built. Mastering this classic is crucial for understanding the essence of the Croque Monsieur.

Ingredients:

• 8 slices of good-quality sandwich bread (French bread, brioche, or Pullman loaf work best)
• 4 tablespoons unsalted butter, divided
• 4 tablespoons all-purpose flour
• 3 cups whole milk
• 1/4 teaspoon ground nutmeg
• Salt and freshly ground black pepper to taste
• 4 tablespoons grated Gruyère cheese, divided
• 8 slices cooked ham (French-style ham or Black Forest ham are excellent choices)
• 4 tablespoons Dijon mustard

Instructions:

1. Prepare the Béchamel Sauce: In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add the flour and whisk constantly for 1-2 minutes until a smooth paste forms (this is called a roux). Be careful not to burn the roux.
2. Gradually whisk in the milk, a little at a time, ensuring each addition is fully incorporated before adding more. This prevents lumps from forming.
3. Continue whisking constantly until the sauce thickens and coats the back of a spoon, about 5-7 minutes.
4. Remove the saucepan from the heat. Stir in the nutmeg, salt, and pepper. Add 2 tablespoons of the grated Gruyère cheese and stir until melted and smooth. Set aside. Keep warm. You can place the pan over a double boiler or very low heat, stirring occasionally, to prevent a skin from forming.
5. Assemble the Sandwiches: Spread Dijon mustard evenly on one side of each slice of bread.
6. On four slices of bread (mustard-side up), layer two slices of ham each.
7. Top with the remaining four slices of bread, mustard-side down.
8. Prepare for Cooking: Preheat your oven to 375°F (190°C).
9. Cook the Sandwiches: Melt the remaining 2 tablespoons of butter in a large skillet or griddle over medium heat.
10. Carefully place the sandwiches in the skillet and cook for 2-3 minutes per side, or until golden brown and slightly toasted.
11. Add the Béchamel and Cheese: Transfer the sandwiches to a baking sheet lined with parchment paper.
12. Spread a generous layer of béchamel sauce evenly over the top of each sandwich.
13. Sprinkle the remaining 2 tablespoons of grated Gruyère cheese over the béchamel sauce.
14. Bake to Perfection: Bake in the preheated oven for 5-7 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
15. Serve Immediately: Remove the sandwiches from the oven and let them cool slightly before serving. Enjoy!

Tips for the Perfect Classic Croque Monsieur:

• Use High-Quality Ingredients: The quality of your ingredients will directly impact the flavor of your Croque Monsieur. Invest in good-quality bread, ham, and Gruyère cheese.
• Don’t Skip the Béchamel: The béchamel sauce is the heart of the Croque Monsieur. Make sure it’s smooth, creamy, and well-seasoned.
• Don’t Overcook the Sandwiches: You want the bread to be golden brown and toasted, but not burnt. Keep a close eye on them while they’re cooking in the skillet and baking in the oven.
• Serve Immediately: Croque Monsieurs are best enjoyed immediately, while the cheese is melted and bubbly and the bread is still crispy.
