The Story Behind the Sandwich
Croque Monsieur, a quintessential French sandwich, has been enjoyed by people worldwide for over a century. The history of the Croque Monsieur dates back to the early 20th century in Paris. It is believed that this iconic sandwich made its debut in 1910 at a Parisian café on Boulevard des Capucines. The name “Croque Monsieur” translates to “Mister Crunch,” a fitting name considering its crispy texture.
The first croque monsieur was simple yet elegant, featuring ham and Gruyère cheese sandwiched between two slices of bread. It wasn’t until the 1930s that a chef enhanced the original sandwich with a layer of béchamel sauce. This decadent version caught on quickly and is considered classic today.
Before long, the fame of the croque monsieur grew, along with many variations, including the feminine version, the croque madame. The croque madame is topped with a fried egg, which is believed to represent a wide-brimmed lady’s hat.
The fame of the croque monsieur grew, and it soon became a beloved dish in many countries. Each culture has put its unique spin on the classic sandwich. For instance, the Monte Cristo sandwich in the United States features turkey, ham, and Swiss cheese, dipped in an egg batter and fried. The Croque Monsieur also inspired various gourmet versions, with some chefs incorporating ingredients like smoked salmon, truffle oil, or even foie gras.

How to Store
Refrigerate: Cover and refrigerate leftovers for up to 2 days. The sandwich may soften but will still reheat well.

Make-ahead note: Assemble the sandwiches without topping them with béchamel; refrigerate up to 1 day, then finish with sauce and cheese before baking.
