The traditional French New Year's Eve feast is called a réveillon.
A réveillon is a long, celebratory meal associated with Christmas Eve or New Year's Eve in French-speaking culture. On New Year's Eve, it is commonly enjoyed late at night or around the midnight transition, with courses that may include seafood, oysters, foie gras, rich desserts, and sparkling wine, depending on the household and region.
The word comes from the French verb réveiller, meaning “to awaken,” reflecting the idea of staying awake for a late-night meal. It describes a meal or celebration rather than one fixed menu.
A common mix-up is treating réveillon as exclusively a Christmas term. French usage applies it to both Christmas Eve and New Year's Eve contexts, although the foods and local customs can differ.
