Equipment Needed

• Small saucepan (for the Béchamel)

• Whisk

• Large skillet or frying pan (oven-safe is ideal)

• Baking sheet or broiler pan

• Chef’s knife and cutting board

• Measuring cups and spoons

Ingredients

For the Béchamel Sauce:

• 2 tablespoons unsalted butter

• 2 tablespoons all-purpose flour

• 1 cup whole milk (warm)

• A pinch of ground nutmeg

• Salt and freshly ground black pepper, to taste

• 1/4 cup freshly grated Gruyère cheese (Stirred right into the sauce)

For the Sandwich Assembly:

• 4 thick slices of artisan white bread, brioche, or sourdough

• 2 tablespoons Dijon mustard

• 6 to 8 ounces high-quality Gruyère cheese, freshly grated (divided)

• 4 to 6 thin slices of premium ham (such as Bayonne, Black Forest, or boiled ham)

• 2 tablespoons unsalted butter (for frying the bread)

Step-by-Step Instructions

Step 1: Make the Homemade Béchamel Sauce

1. In a small saucepan, melt the 2 tablespoons of unsalted butter over medium-low heat.

2. Add the all-purpose flour and whisk constantly for 1 to 2 minutes to cook out the raw flour taste, creating a smooth, pale paste (a roux).

3. Slowly pour in the warm whole milk in a thin stream while whisking vigorously to prevent any lumps from forming.

4. Continue cooking over medium heat, stirring frequently, for 4 to 5 minutes until the sauce thickens enough to coat the back of a spoon.

5. Remove the saucepan from the heat. Stir in the pinch of ground nutmeg, salt, black pepper, and 1/4 cup of grated Gruyère cheese until completely melted and smooth. Set aside.

Step 2: Preheat and Toast the Bread

1. Preheat your oven’s broiler to high, or preheat your oven to 400°F (200°C) if you prefer a slower, more even melt.

2. Melt 1 tablespoon of butter in a large skillet over medium heat. Lightly toast the 4 slices of bread on both sides until golden brown. This prevents the bread from getting soggy under the heavy sauce.

Step 3: Assemble the Sandwiches

1. Arrange the toasted bread slices on a parchment-lined baking sheet.

2. Spread a generous layer of Dijon mustard on the inside of each slice of bread.

3. Layer a generous amount of grated Gruyère cheese onto the bottom two slices, followed by the folded slices of premium ham.

4. Top with the remaining two slices of bread to complete the sandwiches.

Step 4: Coat with Béchamel and Cheese

1. Spoon a generous amount of the warm Béchamel sauce over the top of each assembled sandwich, spreading it evenly to cover the entire top crust.

2. Sprinkle the remaining grated Gruyère cheese heavily over the top of the Béchamel sauce.

Step 5: Broil to Golden Perfection

1. Transfer the baking sheet to the oven on the middle rack (or directly under the broiler if watching closely).

2. Broil for 3 to 5 minutes, keeping a very close eye on it to prevent burning, until the cheese on top is melted, bubbling, and beautifully golden brown with caramelized spots.

Pro Tips for Success

• Use Freshly Grated Gruyère: Pre-packaged shredded cheese contains anti-caking agents that hinder the smooth melting required for an authentic Béchamel and topping. Grating a block of authentic Gruyère yields superior flavor and texture.

• Toast the Bread First: Toasting the bread lightly in butter before assembling prevents the heavy Béchamel sauce from making the interior soggy.

• Serve Immediately: Croque Monsieur is best enjoyed piping hot straight out of the oven while the cheese is at peak stretch and gooey perfection.
