A croque madame is a classic French sandwich made with ham and cheese, typically Gruyère or Emmental, layered between slices of bread. It is similar to the croque monsieur, but the croque madame is topped with a fried or poached egg, adding richness to the dish. The sandwich is often grilled or baked until the cheese melts and the bread is golden brown. This dish is commonly served in cafés and bistros across France and is enjoyed as a breakfast or brunch option. The combination of flavors and textures makes the croque madame a beloved comfort food, appealing to both locals and tourists alike.
