This classic Tom Kha Gai is a beautifully fragrant Thai chicken coconut soup that perfectly balances sour, salty and creamy notes. Infused with aromatic lemongrass, ginger and kaffir lime leaves, the broth offers a light yet deeply satisfying flavour profile. It is an ideal choice for those seeking a dairy-free meal that does not compromise on richness, providing a comforting warmth that makes it a perennial favourite for any time of year.
As a versatile main or a starter, this nourishing soup features tender chicken thighs and earthy mushrooms simmered in a silky coconut base. Serving it with fresh coriander and a squeeze of lime adds a bright, citrusy finish that cuts through the creaminess. Whether you are looking for a quick midweek dinner or an authentic dish to impress guests, this homemade version is remarkably simple to prepare and naturally gluten-free.

How to make Tom Kha Gai (Chicken Coconut Soup)
Using the back of a knife, lightly smash lemongrass and ginger; cut lemongrass into 4" pieces. Bring lemongrass, ginger, lime leaves, and broth to a boil in a large saucepan. Reduce heat and simmer until flavours are melded, 8-10 minutes. Strain broth into clean saucepan; discard solids.
Add chicken and return to a boil. Reduce heat, add mushrooms, and simmer, skimming occasionally, until chicken is cooked through and mushrooms are soft, 20-25 minutes. Mix in coconut milk, fish sauce, and sugar.
Divide soup among bowls. Serve with chilli oil, coriander, and lime wedges.
