Instructions
1Prepare Aromatics
10m
Prepare Lemongrass
Trim the tough ends of the lemongrass stalks and cut them into 2-inch pieces.
Prepare Galangal
Peel the galangal root and slice it into thin pieces. Note: Galangal has a woody texture and a distinct spicy, peppery flavor different from ginger.
Prepare Chilies
Remove stems from the Thai chilies. Adjust quantity to your spice preference.
Prepare Shallots
Peel and dice the shallots.
Prepare Kaffir Lime Leaves
Remove the central stem from the kaffir lime leaves.
2Crush Aromatics
5m
Crush Lemongrass, Galangal, and Chilies
In a mortar and pestle, crush the lemongrass, galangal, and Thai chilies until they form a coarse paste. This releases their essential oils and aroma.
Add Shallots and Lime Leaves
Add the diced shallots and kaffir lime leaves to the mortar and briefly pound to release their fragrance.

10m
Heat Stock
Pour chicken stock into a wok or medium-sized pot and bring to a simmer over medium heat.
Add Aromatics
Add the crushed aromatics mixture to the simmering stock.
Add Seasonings
Stir in palm sugar and fish sauce.
Add Coconut Milk
Pour in the can of coconut milk and stir to combine.
4Cook the Add-ins
15m
Add Tomatoes and Mushrooms
Add the tomato wedges and shimeji mushrooms to the soup.
Add Chicken
Add the sliced chicken breast to the soup. Stir gently to distribute.
Simmer Until Cooked
Simmer the soup gently over medium-low heat for about 10-15 minutes, or until the chicken is fully cooked through and the tomatoes are tender but not falling apart. Stir occasionally.
Remove Tomato Peels
If the tomato peels have loosened, carefully remove them with chopsticks or a spoon.
5Finish and Serve
5m
Add Fresh Herbs
Stir in the chopped cilantro and green onions.
Add Lime Juice
Squeeze in lime juice to taste. Start with about 1/4 cup and add more if desired for a brighter, tangier flavor.
Serve
Ladle the Tom Kha Gai into bowls over cooked jasmine rice. Garnish with extra cilantro and green onions if desired.
Tips
Ensure you use galangal, not ginger, for the authentic Tom Kha Gai flavor.
Adjust the amount of Thai chilies to control the spice level.
Don't overcook the chicken; it should be tender and juicy.
Taste and adjust seasoning with fish sauce, sugar, and lime juice before serving.
