Khao Soi is a curry noodle soup with origins in Northern Thailand, typically made with a rich, coconut-based curry broth, egg noodles, and crispy fried noodles on top for texture. It’s slightly different from the more familiar Southern and Central Thai dishes most people associate with Thai food, offering a deeper, more complex curry flavour. Khao Soi reflects the regional diversity within Thai cuisine, showing that Thai food isn’t a single style but a collection of distinct culinary traditions from different parts of the country.
