National Brioche Day is observed worldwide every May 14 to celebrate brioche, a rich French bread known for its high egg and butter content. This day honors brioche's centuries-old history, with the first recorded use of the word dating back to 1404. The celebration encourages people to enjoy brioche in various forms, whether plain or filled with savory or sweet ingredients such as beef tenderloin, foie gras, or vanilla cream. St Pierre, a baking brand, established National Brioche Day to promote this iconic French specialty and inspire individuals to incorporate brioche into their meals. Participants can join in by purchasing brioches from local bakeries or making them at home, sharing their experiences on social media with the hashtag #NationalBriocheDay.
