The invention of the croque-madame is not due to this mischievous shopkeeper, as this variation of the recipe appeared much later. It is to the addition of an egg to the dish that we owe the feminization of the dish: it would indeed evoke the hat of the women of the time and, by reinforcing the flavor of this sandwich decidedly apart, it would please more the ladies whose taste is, it is well known, finer than that of these gentlemen 😊.
Here's a good recipe to get you started, with or without eggs. And to prepare this atypical dish, which entered the dictionary in 1948, this list of the best croque-monsieur machines will provide you with the right equipment to satisfy both young and old with this now classic bistro dish.
