Ingredients You’ll Need

- 2 cups chicken stock (unsalted, preferably homemade): The flavorful base that keeps the broth light yet savory.
- 1 ½ cups coconut milk: Provides creaminess and rich sweetness that defines the soup’s texture.
- ½ tsp table salt: A modest pinch to enhance all the ingredients without overpowering.
- 1 lb chicken thigh (boneless skinless, cut into 1-inch pieces): Juicy and tender protein that soaks up the aromatic broth beautifully.
- 1 stalk lemongrass (bottom half only, smashed and cut in 2-inch pieces): Adds a fresh, citrusy aroma essential for authentic flavor.
- 12 thin slices galangal: A spicy, pine-like rhizome that gives the soup its distinct zing.
- 5 makrut lime leaves (twisted to bruise and torn into big chunks): Bright and fragrant, these leaves brighten the broth with their citrus notes.
- 1-3 Thai chilies (to taste, smashed or cut into pieces): Offers the signature kick, adjustable to your preferred heat level.
- 2 Tbsp fish sauce: A salty, umami-rich essential that layers the soup with depth.
- 1 tsp finely chopped palm sugar (or granulated sugar): Balances the sour and spicy components with gentle sweetness.
- 5.5 oz oyster mushrooms (torn into bite-size pieces): Adds tender, earthy bits that soak in the flavored broth.
- 2 ½ Tbsp lime juice: Delivers fresh acidity that lifts and brightens the soup just before serving.

How to Make Authentic Tom Kha Gai (Thai Coconut Chicken Soup) Recipe
Step 1: Simmer the Chicken
Start by bringing the chicken stock to a boil in a pot. Once bubbling, add the salt and the cubed chicken thighs. Simmer gently for about 15 minutes until the chicken is tender and cooked through. This slow simmer ensures the chicken stays juicy and imparts savory depth to the broth.
Step 2: Infuse the Flavors
Next, pour in the coconut milk, then add the smashed lemongrass, galangal slices, torn makrut lime leaves, and Thai chilies. Stir in the oyster mushrooms along with half of the fish sauce and palm sugar. Allow everything to simmer gently for 5 minutes. This infuses the broth with those unmistakable Thai herbal and spicy notes, creating a complex flavor experience.
Step 3: Adjust the Seasoning
Time to taste! Add more fish sauce if you like it saltier, then turn off the heat and stir in most of the lime juice. Taste again and add more lime juice as needed to balance the soup’s richness with a zesty punch. Finally, sprinkle with chopped green onions and cilantro for a fresh finish. Remember, the herbs and spices you added for infusion are not meant to be eaten, so remove or inform your guests beforehand.
Step 4: Serve Warm and Comforting
This soup is delightful on its own or served alongside fluffy jasmine rice. It’s warming, nourishing, and truly captures the heart of Thai cuisine.
How to Serve Authentic Tom Kha Gai (Thai Coconut Chicken Soup) Recipe
Garnishes
Topping your soup with freshly chopped green onion and cilantro adds a burst of color and fresh aroma that complements the creamy broth beautifully. Sometimes a few thin slices of fresh red chili can be added for an extra pop of heat and visual appeal.
Side Dishes
This soup shines as part of a larger Thai meal. Serve it with steamed jasmine rice to soak up the luscious broth, and consider pairing it with spicy papaya salad or crisp vegetable spring rolls to bring varied textures and flavors to your table.
Creative Ways to Present
For an impressive presentation, serve the soup in individual small bowls garnished with a sprig of cilantro and a lime wedge on the side. You can also float a few delicate mushroom slices and a chili ring for an attractive look. A rustic wooden bowl or a traditional Thai earthenware dish can enhance the authentic experience at your next dinner gathering.
Make Ahead and Storage
Storing Leftovers
Leftover Authentic Tom Kha Gai (Thai Coconut Chicken Soup) Recipe can be stored in an airtight container in the refrigerator for up to 3 days. The flavors tend to deepen as it sits, making the soup even more delicious the next day.
Freezing
You can freeze the soup for up to 1 month, but keep in mind that the coconut milk can sometimes separate after freezing and thawing. Give the soup a good stir while reheating to bring it back to a creamy texture.
Reheating
Warm the soup gently over low to medium heat on the stove to avoid curdling the coconut milk. Add a splash of fresh lime juice after reheating to revive the brightness and freshness of the flavors.
FAQs
Can I use chicken breast instead of chicken thighs?
Absolutely! While chicken thighs remain tender and juicy, chicken breast can be used if preferred. Just be careful not to overcook it as it tends to dry out faster.
What can I substitute for galangal if I can’t find it?
Fresh ginger is the closest substitute for galangal, offering a similar pungent and spicy flavor, though it’s slightly different. Use fresh ginger slices sparingly as it has a sharper taste.
Is this soup spicy?
The heat level depends on how many Thai chilies you add. You can easily control the spice by using fewer chilies or removing them before serving if you prefer a milder taste.
What is makrut lime leaf, and can I skip it?
Makrut lime leaves add a distinctive citrusy aroma crucial to authentic Thai cuisine. If unavailable, you can add a small strip of lime zest, but the flavor won’t be quite the same.
Can I make this soup vegan or vegetarian?
To make a vegan version, substitute chicken stock with vegetable broth, chicken with firm tofu or mushrooms, and fish sauce with soy sauce or a vegan fish sauce alternative. The soup remains flavorful and comforting!
