Ash reshteh (آش رشته) is a traditional Iranian soup made with noodles, various types of legumes, vegetables, and herbs. It is one of the most famous and popular dishes of Iranian cuisine, and it could be considered Iran’s national soup.
The name “ash reshteh” comes from Persian. The word “ash” (آش) generally refers to thick soups. “Reshteh” (رشته) means noodles, which are the main ingredient of this soup. Iranians believe that long noodles symbolize a long life and prosperity for the family, which is why ash reshteh is often served during special occasions, particularly celebrations associated with wishes for prosperity and longevity.

Ash reshteh is prepared by slowly cooking legumes along with chopped herbs and vegetables. Once the legumes are sufficiently cooked, the noodles are added. The final soup is very thick, filling, and aromatic.
Ash reshteh is traditionally served in deep bowls. The surface is garnished with fried onions, garlic, dried mint, and often also fermented whey kashk. Its sour and salty flavor perfectly complements the taste of the soup.

I tried ash reshteh at a highly touristy spot in the center of Yazd. One portion cost 700,000 IRR (0.80 EUR) and completely filled me up.
Bon appétit!
