Thai Chicken & Coconut Milk Soup
Submitted by joesburrterfly
Tom kha gai, the classic Thai chicken and coconut milk soup with lemongrass, galangal, and lime. Fragrant, silky, and ready in under 30 minutes from a handful of pantry ingredients.

30 minTom kha gai is the Thai soup that teaches you how aromatics work. Three or four slices of galangal, a stalk of bruised lemongrass, grated lime peel, and a pot of coconut milk simmer together until the kitchen smells like a Bangkok side street.
The chicken gets a quick lime-juice bath before it goes into the pot. That acid bath does two jobs: it lightly denatures the surface so the chicken stays silky in the soup, and it primes the meat with brightness that pushes back against the richness of the coconut milk. The chicken poaches just below a boil, never cracking into a hard simmer, so it stays tender.
Fresh cilantro goes on last, raw, for that signature lift.
Pro Tips
- Use real galangal if you can find it. Ginger is fine as a sub but tastes sharper and less piney.
- Never boil coconut milk hard. A gentle simmer keeps the fats emulsified. A hard boil splits the cream.
- Bruise the lemongrass stalk with the back of a knife before slicing. Crushing the fibers releases the citrus oils.
- Fish sauce is traditionally added at the end. A splash rounds out the salt better than plain sea salt.
Variations
- Swap chicken for fresh grouper or shrimp for a seafood version.
- Try slices of kumquat in place of ginger, and use sweet Fresno chiles instead of Thai birds for gentler heat.
- Serve over Vietnamese rice noodles to stretch it into a full dinner bowl.
Ingredients
Directions
Pour the lime juice on the chicken and let stand while you prepare the rest of the soup.
In a medium saucepan, place the coconut milk, lemon grass, grated lime peel, galanga or ginger, and (optionally) chiles.
Bring the coconut milk to a simmer.
When the soup is simmering, add the lime-soaked chicken pieces and stir to distribute them.
Reduce the heat so the soup stays just below a boil and cook for 12 to 15 minutes, or until the chicken pieces are finished cooking.
Remove from heat and serve immediately with fresh cilantro leaves for garnish.
Now, the best way I ever had this soup was with pieces of fresh grouper instead of chicken.
I also added slices of kumquats instead of the ginger, and used the sweet Fresno chiles instead of Thai birds.
We also served it over Vietnamese rice noodles.
