Instructions
Step 1: Prepare the Aromatics
Heat the oil in a large pot over medium heat.
Add the lemongrass, galangal, and kaffir lime leaves. Cook for 2 minutes to release their fragrance.
Step 2: Add the Broth
Pour in the chicken broth and bring it to a gentle boil.
Reduce the heat and simmer for 10 minutes.
Step 3: Add the Chicken
Add the sliced chicken and cook for 5 minutes until it begins to turn white.
Step 4: Add the Mushrooms and Coconut Milk
Stir in the mushrooms and coconut milk.
Simmer for another 5 minutes. Do not allow the soup to boil vigorously because the coconut milk may separate.
Step 5: Season the Soup
Add:
- Fish sauce
- Lime juice
- Brown sugar
- Chili peppers
Taste and adjust the seasoning.
Add more lime juice for extra tanginess.
Add more fish sauce for additional saltiness.
Step 6: Garnish and Serve
Remove the lemongrass pieces and galangal slices if desired.
Sprinkle with fresh cilantro.
Serve hot.
Chef’s Notes
- Authentic Tom Kha Gai uses galangal, not ginger.
- Fish sauce provides the traditional umami flavor and shouldn’t be omitted.
- Full-fat coconut milk produces the creamiest texture.
- The soup should have a balance of four flavors:
- Sweet
- Sour
- Salty
- Spicy
