Tom Kha Kai: The Essential Thai Coconut Chicken Soup Recipe
Explore Tom Kha Kai, a Thai coconut chicken soup infused with galangal, lemongrass, and kaffir lime leaves. We share the authentic recipe with detailed instructions.
August 16, 2024
Tom Kha Kai ranks among the emblematic dishes of Thailand. This creamy coconut chicken soup is built on a foundation of essential Thai aromatics—galangal, lemongrass, and kaffir lime leaves. We'll tell you more about this flavor-rich culinary specialty and share the authentic Tom Kha Kai recipe.
A Word About Tom Kha
In Thai, "Tom" means "to boil" and "Kha" translates to "galangal." In essence, Tom Kha is a fragrant broth built around galangal. While galangal is the star ingredient, this soup is equally defined by a constellation of aromatics—kaffir lime leaves, fresh lime juice, and lemongrass. These tart, floral notes create a beautiful contrast with the richness of coconut milk.
Unlike most Thai soups (such as Tom Yam, green curry, or massaman), Tom Kha doesn't rely on curry paste. For travelers who find spice overwhelming, this is the Thai soup to try—it's one of the rare non-fiery options.
Beyond taste, Tom Kha carries significant medicinal properties thanks to its herbs and spices. Thais traditionally drink it to reduce fever, ease cough, and support digestion. With its high vitamin C content, the soup is also praised for bolstering immune function.

Tom Kha Kai Soup — Chicken, Coconut Milk, and Thai Aromatics
🥢 Note: ingredients are measured for one bowl of soup. Double them as needed.
Preparing Tom Kha Kai
Step 1: Trim the ends of the lemongrass stalks and remove the outer layer. Cut diagonally and crush lightly with the flat of a knife to release the fragrance.
Step 2: Slice the galangal into 6 thick pieces.
Step 3: Clean the mushrooms and tear or cut them into large chunks.
Step 4: Wash and cut the tomato into 6 pieces.
Step 5: Peel and lightly crush the shallots.
Step 6: Cut the chicken into small pieces.
Step 7: In a medium saucepan, bring water to a boil over medium heat with a pinch of salt.
Step 8: Add the chicken, lemongrass, galangal, coriander roots, and shallots. Simmer (over medium heat) for about 4 minutes to coax out all the aromatic flavors from the herbs, stirring gently.
💡 Tip: let the meat cook briefly before stirring—this mellows its rawness and deepens its flavor.
Step 9: Add the mushrooms, tomatoes, and chiles; stir well and return to a boil for 2 minutes until the mushrooms are tender. Add the kaffir lime leaves. Lower the heat, then pour in the coconut milk (this prevents it from separating).
💡 Chef's tip: skim the foam that rises to the surface during cooking for a clear, refined broth.
Step 10: When the coconut aroma becomes fragrant, add the fish sauce and fresh lime juice (it's vital to add lime juice at the end to avoid bitterness). Stir gently, taste, and adjust seasoning to your preference.
Step 11: Serve immediately in a bowl.
Step 12: Finally, garnish with dried red chiles, fresh cilantro, and serve alongside steamed jasmine rice.
🥢 Note: aromatics such as galangal, kaffir lime leaves, and lemongrass are used to perfume the broth and aren't meant to be eaten. You can leave them at the bottom of the bowl to continue releasing flavor as you eat, or remove them just before serving.
