A Croque Madame is a classic French sandwich that features layers of ham and cheese, typically made with Gruyère or Emmental cheese, sandwiched between slices of bread. The sandwich is then toasted or grilled until the cheese melts and the bread becomes golden brown. It is often served with a creamy béchamel sauce, adding richness to the dish. What sets the Croque Madame apart from its counterpart, the Croque Monsieur, is the addition of a fried or poached egg on top. This egg adds a delightful creaminess when cut into, enhancing the overall flavor and texture of the sandwich. The Croque Madame is a popular choice for brunch or a light meal in French cuisine.
