Croque Monsieur — French Ham & Cheese Sandwich

A Croque Monsieur is the ultimate French comfort-food sandwich: crisp golden bread layered with savory ham, melted Gruyère cheese, and a creamy béchamel sauce. It’s toasted until bubbling, beautifully browned, and irresistibly cheesy.

This classic French sandwich is perfect for a cozy breakfast, brunch, lunch, or a simple café-style dinner at home.

🛒 Ingredients

For the Sandwich

• 8 slices white sandwich bread or brioche
• 8 slices good-quality ham
• 1½ cups grated Gruyère cheese
• 2 tablespoons Dijon mustard
• 2 tablespoons butter

For the Béchamel

• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• Pinch of nutmeg
• ¼ cup grated Gruyère or Parmesan

👩‍🍳 Instructions

1. Make the Béchamel

Melt 2 tablespoons butter in a small saucepan over medium heat. Whisk in the flour and cook for about 1 minute.

Gradually pour in the milk while whisking continuously to prevent lumps. Continue cooking for 3–5 minutes until the sauce becomes smooth and thick.

Season with salt, pepper, and a small pinch of nutmeg. Stir in the grated cheese until melted. Remove from the heat.

2. Build the Sandwiches

Spread a thin layer of Dijon mustard over four slices of bread.

Add 2 slices of ham to each, followed by a generous handful of Gruyère.

Top with the remaining slices of bread.

3. Toast the Sandwiches

Heat a skillet over medium heat and melt the remaining butter.

Place the sandwiches in the skillet and cook for about 2–3 minutes per side, until golden brown and crisp.

4. Add the Béchamel

Transfer the toasted sandwiches to a baking sheet.

Spread a generous layer of béchamel over the top of each sandwich. Sprinkle with additional Gruyère.

5. Broil

Place under a hot broiler for 2–4 minutes, watching carefully, until the cheese is bubbling and golden brown.

Let cool for a minute or two before serving.

⭐ Pro Tips

• Use Gruyère for the classic nutty, rich flavor, but Comté or Emmental also works beautifully.
• Don’t make the béchamel too thin; it should be thick enough to sit on top of the sandwich.
• Use slightly sturdy bread so it doesn’t become soggy.
• For an extra-crispy sandwich, lightly butter the outside of the bread before pan-toasting.
• Watch the broiler carefully—the cheese can go from golden to burnt very quickly.

🍽️ What to Serve With It

Serve your Croque Monsieur with:

• A simple green salad

❓Q&A

What cheese is traditionally used?
Gruyère is one of the most traditional choices. Comté or Emmental are excellent alternatives.

Can I make it without béchamel?
Yes, but béchamel is what gives a classic Croque Monsieur its creamy, luxurious topping.

Can I use regular sliced ham?
Absolutely. Thinly sliced deli ham works well, although a good-quality French-style ham gives the sandwich more flavor.

Can I prepare it ahead?
You can assemble the sandwiches ahead of time and refrigerate them for a few hours. Add the béchamel shortly before baking for the best texture.
