Welcome to a complete, easy-to-follow guide for making the Best Ever Tom Kha Gai — authentic Thai coconut soup.

Introduction
Tom Kha Gai, often called Thai coconut soup, combines a rich coconut milk base with aromatic herbs and spices like lemongrass, galangal (or ginger), lime, and chilies. The result is a soup that is simultaneously creamy, citrusy, and mildly spicy. Traditionally served with chicken, the soup easily adapts to tofu, shrimp, or a fully plant-based version. It’s ideal for chilly evenings, light lunches, or as part of a Thai-style meal with rice and simple sides.
Ingredients for Best Ever Tom Kha Gai
Gather the following ingredients to make about 4 servings:
- 1 tablespoon coconut oil
- 1/2 medium onion, thinly sliced
- 2 garlic cloves, chopped
- 1/2 red jalapeño, sliced (or 1–3 Thai chiles, halved, to taste)
- 3 slices (about 1/4 inch each) galangal or ginger
- 1 lemongrass stalk, lightly crushed and cut into 2-inch pieces
- 2 teaspoons red curry paste
- 4 cups chicken broth (substitute vegetable broth for vegan/Whole30)
- 4 cups full-fat canned coconut cream (unsweetened; use full-fat coconut milk for a lighter soup)
- 2 medium chicken breasts, cut into bite-sized pieces (about 1 lb) — or substitute tofu or shrimp
- 8 ounces white mushrooms, sliced
- 1–2 tablespoons coconut sugar (optional)
- 1 1/2–2 tablespoons fish sauce (use coconut aminos for vegan/Whole30)
- 2–3 tablespoons fresh lime juice
- 2–3 green onions, thinly sliced
- Fresh cilantro, chopped, for garnish
How to Make Best Ever Tom Kha Gai – Step by Step
Step 1:
Heat the coconut oil in a medium pot over medium heat. Add the sliced onion, garlic, jalapeño or Thai chiles, galangal or ginger, lemongrass, and red curry paste. Stir frequently and cook for about 5 minutes, until the onion softens and the aromatics release their fragrance.
Step 2:
Pour in the chicken (or vegetable) broth and bring it to a boil. Once boiling, reduce the heat and let it simmer uncovered for 30 minutes so the broth can absorb the aromatics.
Step 3:
Strain the broth through a fine sieve to remove the cooked aromatics — discard the solids. You will be left with a deeply flavored, aromatic broth.
Step 4:
Return the strained broth to the pot and stir in the coconut cream (or coconut milk). Add the chicken pieces (or tofu/shrimp) and the sliced mushrooms. Simmer gently until the protein is cooked through — about 8–12 minutes for chicken, less for shrimp.
Step 5:
Season the soup with fish sauce or coconut aminos, coconut sugar if using, and fresh lime juice. Taste and adjust seasoning: add more lime for brightness, more fish sauce for saltiness, or a touch of sugar to balance the acidity.
Step 6:
Simmer for another 1–2 minutes, then serve immediately. Garnish each bowl with sliced green onions and chopped cilantro.
Helpful Tips for Best Ever Tom Kha Gai
- Use fresh aromatics: Fresh lemongrass, galangal (or fresh ginger), and fresh lime juice give Tom Kha Gai its authentic, vibrant flavor.
- Control the heat: Adjust chilies to suit your tolerance. Use fewer or remove seeds for a milder soup.
- Infuse the broth: Simmering the broth with aromatics and then straining is the key step that produces the soup’s characteristic depth.
- Make it vegan: Replace chicken with firm tofu or extra mushrooms and use vegetable broth plus coconut aminos instead of fish sauce.
Cooking Tips for the Best Ever Tom Kha Gai
- Best cookware: A heavy-bottomed pot or Dutch oven ensures even heat distribution and prevents scorching.
- Simmer, don’t boil: After adding coconut cream, keep the heat low to avoid separation or curdling of the coconut.
- Serve fresh: Tom Kha Gai tastes best right away, when the herbs and lime are at their brightest.
