Tom Kha Gai (Galangal and Lemongrass Chicken Soup)
A vibrant, aromatic soup where pasture-raised chicken simmers in a fragrant broth of galangal, lemongrass, and kaffir lime leaves. Creaminess comes solely from organic coconut milk, while fish sauce and fresh lime juice provide the signature salty-sour balance without refined sugar.
A little context
Tom Kha Gai is a staple of Central Thai cuisine, traditionally balanced with palm sugar. We honor the tradition by omitting the refined sugar entirely, relying on the natural sweetness of mushrooms and the depth of a homemade bone broth. By sourcing sugar-free fish sauce and fresh aromatics, we preserve the authentic flavor profile while aligning with modern longevity standards.
The longevity story
This dish leverages the anti-inflammatory properties of galangal and lemongrass, which contain bioactive compounds like galangin and citral that support immune function. The collagen-rich chicken bone broth provides amino acids essential for gut lining integrity, while the kaffir lime leaves offer high concentrations of vitamin C and polyphenols. Coconut milk supplies medium-chain triglycerides (MCTs) for sustained energy without spiking insulin, and the herbs act as natural digestive aids.
Method
- 01
Prepare the aromatics
Bruise the lemongrass stalks firmly with the side of your knife or pestle to release essential oils, then cut them into 5 cm lengths. Slice the galangal into thin coins and tear the kaffir lime leaves.
- 02
Simmer the broth base
In the stockpot, combine the homemade chicken bone broth, lemongrass, galangal, and kaffir lime leaves. Bring to a gentle simmer over medium heat and cook for 15 minutes to infuse the flavors.
- 03
Poach the chicken
Add the pasture-raised chicken thighs to the simmering broth. Cook for 10 minutes until the chicken is cooked through but not tough. Do not let it boil vigorously.
- 04
Add mushrooms and coconut milk
Stir in the oyster mushrooms and the organic coconut milk. Return to a low simmer for 5 minutes until the mushrooms are tender. Do not boil after adding coconut milk to prevent curdling.
- 05
Season the soup
Remove the pot from heat. Stir in the sugar-free fish sauce and fresh lime juice. Taste carefully; the balance should be salty, sour, and savory without added sweetness.
- 06
Serve immediately
Ladle into bowls, discarding the lemongrass and galangal pieces (or leaving them for visual appeal). Top with fresh cilantro and sliced Thai chilies.
Pro tips
- ✦Source galangal at an Asian grocery store; it looks like ginger but has a sharper, citrusy flavor that is non-negotiable for authenticity.
- ✦Check fish sauce labels carefully; many brands add cane sugar. Look for 'Red Boat' or similar brands that list only anchovies and salt.
- ✦Bruise the lemongrass aggressively; if you don't, the soup will lack the signature floral aroma.
- ✦Add the lime juice off the heat to preserve the volatile polyphenols and prevent bitterness.
- ✦For a richer broth, skim the fat from the homemade bone broth before simmering, or leave it for extra satiety.

FAQ
Can I use coconut cream instead of coconut milk?+
Yes, coconut cream is thicker and richer. Dilute with a little broth to reach soup consistency.
Why is my soup bitter?+
This usually happens if you boil the coconut milk or add lime juice while the pot is boiling. Always remove from heat before adding acid.
Is this compatible with strict Blueprint protocols?+
Yes, provided the fish sauce is sugar-free and the coconut milk has no additives. It fits the no-refined-sugar and whole-food criteria.
