Thai Boiled Chicken
Thai Poached Chicken in Fragrant Herb Broth
Chicken thighs gently simmer in a deeply aromatic broth built from galangal, lemongrass, and coriander root. This gentle cooking method keeps the meat incredibly tender while infusing it with layers of Thai herbs and umami from fish sauce.
The word "khao tom" might translate to "boiled rice," but this dish is really about the chicken — and more specifically, about the deeply aromatic broth that transforms simple thighs into something extraordinary. Thai cooks have mastered the art of gentle poaching, understanding that low heat and patience create textures no amount of high-temperature searing can match.
What sets this apart from other poached chicken dishes is the foundation of aromatics. Galangal brings a sharp, almost piney heat that's completely different from ginger. Coriander root — not the leaves or seeds — adds an earthy depth you can't get anywhere else. Lemongrass contributes citrus without acidity. Together, they create a broth so fragrant and complex that it becomes the star alongside the chicken.
This isn't quick weeknight cooking, but it's not complicated either. The technique is forgiving — as long as you keep the heat gentle and don't rush the simmering, the chicken will stay incredibly tender. The reward is meat that falls off the bone and a pot of liquid gold that makes every grain of rice it touches taste like it was cooked in the best Thai restaurant.
Ingredients
- 4¼ cupwater
- 5 clovegarlic cloves, smashed with the flat side of a knife
- 3 fresh coriander root, washed and chopped
- 2 stalklemongrass stalks, bruised and cut into 3-inch pieces
- 5 slicefresh galangal slices, about ¼-inch thick
- 4 tbspfish sauce
- ½ tbspdark soy sauce (for color)
- 2 tbsplight soy sauce
- 1 tspground white pepper
- 1½ tbsppalm sugar or brown sugar
- 1⅓ lbbone-in, skin-on chicken thighs
Instructions
- Fill a heavy-bottomed pot with the water and place over medium heat. Drop in the smashed garlic, coriander root, lemongrass pieces, and galangal slices. Cover the pot and bring everything to a rolling boil — this will take about 10 minutes and helps extract maximum flavor from the aromatics.
- Once boiling, add the fish sauce, light soy sauce, dark soy sauce, white pepper, and palm sugar to the pot. Stir everything together until the sugar completely dissolves, about 30 seconds. The broth should taste balanced — salty, slightly sweet, with a gentle heat from the white pepper.
- Carefully nestle the chicken thighs into the simmering broth in a single layer. They should be about half-submerged — don't worry if they're not completely covered. Cover the pot with a lid to trap the steam and maintain gentle heat circulation.
- Lower the heat to maintain a very gentle simmer — you want just a few lazy bubbles breaking the surface. Cook for 45 minutes total, flipping the thighs once at the halfway point so both sides absorb the flavors evenly. The chicken is done when it easily pulls away from the bone and the juices run clear.⏱ 45 min
- Remove the pot from heat and let the chicken rest in the warm broth for several minutes — this final resting keeps the meat juicy. Serve the chicken with jasmine rice and ladle some of the fragrant cooking broth over everything.
Tips & Tricks
- Smash the garlic and coriander root with the flat side of your knife before adding them — this releases more oils than just chopping would.
- Don't skip the dark soy sauce even though it's a small amount; it adds color and a subtle molasses note that balances the fish sauce's saltiness.
- If your chicken thighs are different sizes, start the larger ones first and add smaller pieces a few minutes later so everything finishes at the same time.
- Save the leftover broth — it makes an incredible base for soup or can be used to cook rice for an even more flavorful side dish.
- The chicken will look pale when done, which is normal for poaching; the flavor is all absorbed into the meat rather than developed on the surface.
Frequently Asked Questions
Can I use chicken breasts instead of thighs?
You can, but reduce the cooking time to about 25-30 minutes and check for doneness earlier. Breasts will be less forgiving if overcooked and won't have the same rich flavor that thighs develop.
What if I can't find coriander root or galangal?
Asian grocery stores usually carry both, often in the freezer section. In a pinch, substitute ginger for galangal and use extra garlic plus a pinch of ground coriander for the root, though the flavor will be noticeably different.
Can this be made ahead of time?
Yes, the chicken actually improves when left to cool in the broth and reheated gently later. Store everything together in the fridge for up to 3 days and reheat slowly over low heat.
Why does the recipe call for both light and dark soy sauce?
Light soy sauce provides the primary saltiness, while dark soy sauce adds color and a deeper, slightly sweet flavor. Using both creates the complexity that makes Thai cooking so distinctive.
