What is a Croque Monsieur?

The Croque Monsieur (pronounced croak mess-yer) is a traditional French sandwich made with ham and cheese, grilled or baked until crispy and golden. It’s often topped with a generous layer of béchamel sauce (a creamy white sauce) and extra melted cheese.

Think of it as the sophisticated cousin of grilled cheese — only more indulgent and bursting with flavor.

Ingredients (Serves 2):

For the sandwich:

• 4 thick slices of white or country bread
• 4 slices of cooked ham or smoked turkey
• 4 slices of Gruyère or Emmental cheese
• 1 cup grated cheese for topping (Gruyère is best)
• 1 tablespoon butter (for spreading on bread)

For the béchamel sauce:

• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk
• Salt to taste
• A pinch of ground nutmeg
• Black pepper to taste

Step-by-Step Instructions:

1. Prepare the Béchamel Sauce

This creamy sauce gives Croque Monsieur its signature richness.

1. In a saucepan over medium heat, melt 2 tablespoons of butter.
2. Add 2 tablespoons of flour, whisking continuously until it forms a smooth paste.
3. Gradually pour in the milk, whisking to avoid lumps.
4. Season with salt, pepper, and a pinch of nutmeg.
5. Cook for 3–5 minutes until the sauce thickens. Set aside.

Tip: Don’t let it boil too fast. Keep the heat medium to avoid burning the milk.

2. Assemble the Sandwiches

1. Butter one side of each bread slice.
2. On the unbuttered side, layer: cheese → ham → cheese again.
3. Close the sandwich with the buttered side facing out.

3. Grill the Sandwiches

1. Heat a skillet or grill pan over medium heat.
2. Place the sandwiches and cook each side until golden and crisp (about 2–3 minutes per side).
3. Remove from the pan and place on a baking tray.

4. Add Béchamel and Finish in the Oven

1. Spoon béchamel sauce over the top of each sandwich.
2. Sprinkle with the grated cheese.
3. Broil or bake in a preheated oven at 400°F (200°C) for 5–7 minutes, until the cheese is melted and bubbly.

Serving Suggestions:

• Serve with a simple green salad or roasted potatoes for a complete meal.
• Best enjoyed hot, straight from the oven. Garlic Butter Steak with Cheesy Herb Pasta
