A croque-madame is a variation on the croque-monsieur, a French twist on grilled ham and cheese sandwich. Made with crème fraiche rather than béchamel, this classic variation of croque monsieur is delicious and super quick to make.
Preparation time: 10 minutes
Cooking time: 8 minutes
You will need
1. Preheat the oven to 180°C/350°F/gas mark 5
2. Spread the butter on both sides of the bread, then spread one side with Dijon mustard. Spread on one tablespoon of crème fraiche, sprinkle on half the grated cheese and lay on the slice of ham and sandwich together. Spread the top layer of the sandwiches with the rest of the crème fraiche, then sprinkle with the rest of the cheese.
3. Place the sandwich on a baking sheet and bake for six to seven minutes until the cheese has melted and gone gooey on top.
