Gaeng Om Soup (Thailand)

The Gaeng Om Soup is a clear Thai chicken soup with Isan herbs, in a water-based curry that does not require coconut milk.

Even the curry paste (nam pla ra) is not the typical green Thai curry paste or massaman curry, but a light and simple paste, only 5 ingredients: lemongrass, galangal, chilies, shallots, and garlic.

Gaeng: in Thai it translates to “curry” or “soup”.
Om: refers to a type of Isan food, a water-based curry prepared without coconut milk, with many seasonal and regional vegetables.

This is a typical recipe from Northeast Thailand, always prepared with dill, which gives it its characteristic flavor.

During the trip to Ao Nang in October 2024 with my mother, we tasted the Gaeng Om Soup at Jungle Kitchen restaurant, and my mother opted for a version with shrimp.
