Discover this delicious recipe of croque-monsieur propose by the chef Juan Arbelaez.

Born in Bogota, Colombia, Juan has always dreamed of moving to Paris.

Always an admirer of French cuisine, Juan took his courage in both hands, left his family and his hometown and arrived in Paris. At the age of 18, the ambitious young man joined the prestigious Le Cordon Bleu school as an assistant and graduated at the top of his class. It was with Pierre Gagnaire, a three-starred chef, that Juan began his career.

Juan will then integrate two Parisian palaces on the right bank: the George V with Éric Briffard and the Bristol with Éric Frechon.

Thanks to his numerous experiences, Juan wishes to write a career in his own name by advocating an accessible and sharing cuisine.
