Classic Croque Monsieur – The Ultimate French Grilled Cheese

Instructions

1. Make the Béchamel Sauce:

• In a small saucepan, melt the butter over medium heat.

• Whisk in the flour and cook for 1-2 minutes until golden (this is a roux).

• Gradually pour in the warm milk, whisking constantly to avoid lumps.

• Cook for 3-4 minutes until thickened.

• Season with salt, pepper, and nutmeg.

• Remove from heat and stir in the ½ cup Gruyère until melted. Set aside.

2. Assemble the Sandwiches:

• Preheat the broiler (grill) on high.

• Lightly toast the bread slices (optional for extra crunch).

• Spread a thin layer of Dijon mustard on two slices (if using).

• Layer each with 2 slices of ham and half of the remaining Gruyère.

• Top with the remaining bread slices.

3. Grill the Sandwiches:

• Heat a skillet over medium heat and melt 1 tbsp butter.

• Add the sandwiches and cook for 2-3 minutes per side until golden.

• Transfer to a baking sheet.

4. Add the Béchamel & Broil:

• Spread a generous layer of béchamel over the top of each sandwich.

• Sprinkle with extra Gruyère (optional for extra cheesiness).

• Broil for 2-3 minutes until bubbly and golden brown.

5. Serve Immediately:

• Let cool slightly, then cut in half and enjoy hot!

Optional Upgrade:

• Croque Madame: Fry an egg sunny-side up and place it on top of the sandwich before serving.
