National Shawarma Day is observed worldwide every October 15, celebrating the popular Middle Eastern dish known as shawarma. This dish, which consists of seasoned and marinated meat such as lamb, beef, chicken, or turkey cooked on a vertical rotisserie, has its origins in the Ottoman Empire and is related to the Turkish döner kebab and Greek gyros. The holiday was founded in 2020 by Osmow’s, a Mediterranean and Middle Eastern fast casual chain, to honor one of its signature dishes. People celebrate by enjoying shawarma with friends, often taking advantage of promotions and discounts offered by restaurants. Typical accompaniments for shawarma include fresh vegetables, pickles, and sauces like toum or tarator, depending on the type of meat. The day encourages social media sharing, inviting participants to post photos of their shawarma with the hashtag #NationalShawarmaDay.
