Thai Coconut Dumpling Soup with Lime and Galangal (Tom Kha-Style)
A fragrant coconut broth infused with galangal and lime leaf, filled with silky pork dumplings instead of the usual chicken.
About This Recipe
This soup borrows the aromatic backbone of tom kha gai -- coconut milk, galangal, lemongrass, makrut lime leaves, and a sour-salty finish of lime and fish sauce -- and pairs it with simple pork dumplings instead of sliced chicken, an adaptation more common in home kitchens looking to stretch the broth into a heartier one-bowl meal. The broth itself stays true to tradition: galangal and lemongrass are bruised and simmered to release their oils, never blended in, since the aromatics are meant to be fished out or left whole for flavor rather than eaten. The technique that matters is balancing the coconut milk's richness against the broth's sourness -- too much lime and it curdles the coconut milk, too little and the soup tastes flat and heavy. Adding lime juice off the heat, right before serving, keeps the broth from splitting and preserves its bright top note. Served hot with a scattering of cilantro and extra chile, this soup sits between Thai and Chinese traditions: the aromatics are unmistakably Thai, the dumpling format leans toward home-style Chinese-Thai cooking common in Bangkok's mixed culinary neighborhoods.

Pro Tips
- →
Bruise the lemongrass with the back of a knife before adding it -- this releases the oils that flavor the broth.
- →
Add lime juice only after removing the pot from heat; boiling it can cause the coconut milk to curdle.
- →
The galangal, lemongrass, and lime leaves are aromatics, not meant to be eaten -- warn guests to push them aside.
Variations
- •
Use shrimp dumplings instead of pork for a lighter, seafood-forward version.
- •
Swap dumplings for sliced chicken breast for a closer version of classic tom kha gai.
- •
Add sliced mushrooms to the broth for extra texture, common in restaurant versions.
Storage
Store broth and uncooked dumplings separately for up to 2 days; cooked dumplings can turn mushy if left sitting in broth. Reheat broth gently and add fresh-cooked dumplings when serving.
History & Origin
Tom kha gai is a well-documented Thai soup built on coconut milk and galangal, a rhizome distinct from ginger that gives the broth its citrusy, peppery aroma. Dumpling soups reflect the strong Chinese-Thai culinary crossover found in Bangkok, where Teochew immigrant cooking has long blended with Thai flavors.
Frequently Asked Questions
Can I use frozen store-bought dumplings?
Yes, plain pork or chicken dumplings work well -- just simmer them a couple minutes longer since they're frozen, until they float and are heated through.
What if I can't find galangal or lime leaves?
Fresh ginger is an acceptable substitute for galangal, though the flavor is milder and less citrusy; lime zest can stand in for lime leaves in a pinch.
Why did my coconut broth look curdled?
This usually happens when acid (lime juice) is added while the broth is still boiling hard -- always add it off the heat, once the pot has stopped simmering.
