About this recipe
A croque monsieur is the French café's answer to a ham and cheese sandwich, and it is gloriously rich. Ham and Gruyère go inside, then the whole sandwich is topped with a nutmeg-scented béchamel sauce and more cheese and baked until bubbling.
Add a fried egg on top and it becomes a croque madame. Serve it with a crisp green salad to balance the richness.
Equipment you'll need
- Small saucepan
- Whisk
- Rimmed baking sheet
Tips for success
- Whisk constantly while adding the milk to avoid lumps in the béchamel.
- Watch the sandwiches under the broiler; they go from golden to burnt very quickly.
- For a croque madame, top each sandwich with a fried egg just before serving.
Substitutions and variations
- Use Emmental or Comté instead of Gruyère.
- Use turkey instead of ham.
- Make it vegetarian with sautéed mushrooms in place of ham.
Storage and reheating
To store: Best eaten hot. Refrigerate leftovers for up to 2 days.
To reheat: Reheat in a 350°F (175°C) oven for 10 minutes until hot throughout.

Instructions
Step 1: Make the béchamel
Melt the butter in the saucepan over medium heat, whisk in the flour and cook for 1 minute. Gradually whisk in the milk and simmer, whisking, for 3 to 4 minutes until thick. Season with nutmeg, salt and pepper.
Step 2: Toast the bread
Heat the oven to 400°F (200°C). Arrange the bread on the baking sheet and toast for 3 to 4 minutes, turning once, until lightly golden.
Step 3: Assemble
Spread 4 slices thinly with mustard and a little béchamel. Top with the ham and half the Gruyère, then close with the remaining slices.
Step 4: Top
Spread the remaining béchamel over the tops of the sandwiches and sprinkle with the rest of the Gruyère.
Step 5: Bake and broil
Bake for 8 to 10 minutes until heated through, then broil for 1 to 2 minutes, watching closely, until golden and bubbling. Serve hot.
