Aush reshteh or aush-e-reshteh (Persian: آش رشته) is a type of aush (Iranian thick soup) featuring reshteh (thin noodles) and kashk (a dairy product, made from cooked or dried yogurt), commonly made in Iran and Azerbaijan. 
There are more than 50 types of thick soup (aush) in Iranian cooking, this being one of the more popular types. The ingredients used are reshteh (thin noodles), kashk (a whey-like, fermented dairy product), herbs such as parsley, spinach, dill, spring onion ends and sometimes coriander, chick peas, black eye beans, lentils, onions, flour, dried mint, garlic, oil, salt and pepper. This is a soup that is vegetarian but can easily be made vegan by omitting the kashk; alternatively, meat can be added.
Aush reshteh is an ancient soup that changed in recipe over time and by A.D. 500 the noodles were introduced to the dish, making it more closely related to the present day recipe. Traditionally, aush reshteh is served at special Iranian events, like Nowruz, Sizdah be-dar, or during winter time. The noodles are supposed to symbolize good fortune for the new year. It is cooked most in autumn and winter.
