National Chop Suey Day is observed in the United States every August 29.

The dish is believed to have originated in southern China and was adapted by Chinese immigrants in the U.S. who modified recipes to suit local tastes and available ingredients. While chop suey is a popular choice for takeout, it can also be easily made at home. The holiday encourages people to enjoy chop suey from their favorite restaurants or try variations from different cuisines, such as Filipino or Polynesian. Although the exact origin of National Chop Suey Day is unclear, it serves as a fun occasion to indulge in this beloved dish.
