Traditional Thai Tom Kha Gai Coconut Soup

Authentic Tom Kha Gai Soup

Introduction

Authentic Tom Kha Gai Soup is a classic Thai coconut chicken soup known for its creamy texture and bright, aromatic flavor. The name translates to “chicken galangal soup,” highlighting one of its key ingredients. This comforting dish balances richness from coconut milk with citrusy lime, savory fish sauce, and fragrant herbs.

What makes Authentic Tom Kha Gai Soup truly distinctive is its harmony of flavors. Creamy, tangy, slightly spicy, and deeply aromatic elements work together in every spoonful. Tender chicken and mushrooms float in a silky broth infused with lemongrass and galangal.

This soup is both satisfying and refreshing. It can be served as a starter or enjoyed as a light main dish alongside jasmine rice. With fresh ingredients and careful simmering, this recipe delivers authentic Thai character in your own kitchen.

Ingredients Overview

Boneless, skinless chicken breast or thigh is traditionally used. Thin slices cook quickly and stay tender in the hot broth. Thigh meat offers slightly richer flavor.

Coconut milk forms the creamy base. Use full-fat coconut milk for authentic richness and body.

Galangal is essential for traditional flavor. It has a citrusy, pine-like aroma distinct from ginger. If unavailable, fresh ginger can be used, though the flavor will differ slightly.

Lemongrass adds bright citrus fragrance. Use the tender inner portion of the stalk, lightly bruised to release oils.

Kaffir lime leaves provide a unique floral aroma. Tear them slightly before adding to the broth.

Mushrooms, typically straw mushrooms or button mushrooms, add texture and absorb the flavorful broth.

Fish sauce brings savory depth and saltiness. It is a key component of authentic Thai cuisine.

Fresh lime juice adds acidity and balance. Add it at the end to preserve its brightness.

Thai bird’s eye chilies contribute gentle heat. Adjust according to spice preference.

Fresh cilantro is used for garnish.

Chicken broth supports the coconut milk and enhances savory flavor.

Step-by-Step Instructions

In a medium pot, combine chicken broth and half of the coconut milk over medium heat.

Add sliced galangal, bruised lemongrass, and torn kaffir lime leaves. Bring to a gentle simmer and cook for about 5 minutes to infuse the broth with aroma.

Add thinly sliced chicken to the simmering broth. Cook for 5 to 7 minutes until the chicken is just cooked through.

Stir in sliced mushrooms and continue simmering for another 3 to 4 minutes.

Reduce heat slightly and add the remaining coconut milk. Stir gently to combine.

Season the soup with fish sauce and sliced Thai chilies. Simmer gently for 2 to 3 minutes. Avoid boiling rapidly, as this can affect the texture of the coconut milk.

Remove the pot from heat. Stir in fresh lime juice.

Taste and adjust seasoning as needed. You may add more fish sauce for saltiness or lime juice for acidity.

Ladle the soup into bowls. Garnish with chopped fresh cilantro.

Before serving, remove large pieces of lemongrass and galangal if desired, as they are typically not eaten.

Avoid overcooking the chicken, as it can become firm if simmered too long.

Tips, Variations & Substitutions

For a richer broth, use chicken thighs instead of breast meat.

If you cannot find galangal, substitute fresh ginger, though the flavor will not be identical.

To make the soup vegetarian, replace chicken with tofu and use vegetable broth and soy sauce instead of fish sauce.

Add cherry tomatoes for slight sweetness and color.

For a creamier texture, increase coconut milk slightly and reduce broth proportion.

Authentic Tom Kha Gai Soup can be stored in the refrigerator for up to three days. Reheat gently to avoid separating the coconut milk.
