Thai Coconut Chicken Broth

Steps

1. 1

   Prepare aromatics and bones

   • Rinse chicken bones under cold running water until the water runs clear; set aside.
   • Using a knife handle or the flat side of a heavy knife blade, smash each lemongrass stalk to crush and release the aromatic oils.
   • Peel the ginger root, then slice it into ¼-inch (6 mm) rounds.
   • Peel the galangal the same way and slice into ¼-inch rounds.
   • Halve the onion (leaving the papery skin intact to add color to the broth) and peel the garlic cloves.

   Tip: Keep the onion skin on—it will add a golden hue to your finished broth

2. 2

   Blanch the bones

   • Fill a large pot with enough water to cover the chicken bones by 1 inch.
   • Bring to a rolling boil over high heat (about 5 minutes).
   • Add the rinsed bones and blanch for 2 minutes.
   • Pour the contents through a colander, discarding the water.
   • Rinse the bones and the colander under cold water until the water runs clear.
   • Set the blanched bones aside.

   Ready when: Bones are no longer cloudy and water runs clear

   Tip: Blanching removes impurities that would cloud the broth; don't skip this step for a refined final result

3. 3

   Simmer the broth

   • In a large pot (6–8 quart capacity), add 10 cups of cold water and bring to a boil over high heat (about 5–8 minutes).
   • Add the blanched bones, halved onion, peeled garlic cloves, sliced ginger, sliced galangal, smashed lemongrass, and fish sauce.
   • Return to a gentle boil, then reduce the heat to low and maintain a barely-bubbling simmer—the surface should show only small bubbles breaking, not a rolling boil.
   • Simmer for 2 hours (120 minutes).
   • Every 30 minutes, skim off any gray foam or impurities that rise to the surface using a shallow spoon or small ladle, and discard them.
   • After 2 hours, the broth should smell deeply fragrant with floral and herbaceous notes; the bones will have released some gelatinous material into the liquid.

   Ready when: Broth is fragrant and has a pale golden color; bones have released their gelatin into the liquid

   Tip: Keep the simmer gentle—a rolling boil will break down bones too quickly, making the broth cloudy and bitter

4. 4

   Strain the broth

   • Set a fine-mesh strainer over a large heatproof bowl.
   • Using tongs or a slotted spoon, carefully transfer any large bones from the pot to the strainer, then slowly pour the hot broth through the strainer into the bowl.
   • Let the strainer drain fully (about 2–3 minutes), but do not press or force the solids—this will cloud the broth.
   • Discard the solids.
   • You should have approximately 7–8 cups of strained broth (some liquid will have evaporated during simmering).
   • Return the strained broth to the cleaned pot.

   Ready when: Broth is clear and golden; all solids have been removed

   Tip: Do not press the solids to extract more liquid—let the broth drain naturally for a clear, refined result

5. 5

   Finish with coconut milk and lime

   • Place the pot of strained broth over medium heat.
   • When the broth begins to steam and show small bubbles (do not let it boil hard), reduce the heat to medium-low.
   • Pour the full 1.5 cups of canned coconut milk into the broth, stirring gently with a wooden spoon until the cream is fully incorporated and the broth is pale and smooth (1–2 minutes).
   • The broth should now be creamy and pale golden.
   • Cut the 2 limes in half, juice them through a fine strainer (to catch seeds), and add the juice to the broth, stirring to combine.
   • Taste a small spoonful and add salt as needed (typically ½ to 1 full teaspoon kosher salt will bring out all the flavors).
   • The finished broth should taste bright and balanced—the lime and fish sauce should shine without overpowering the coconut and floral aromatics.

   Ready when: Broth is hot and steaming, creamy, well-seasoned, and fragrant

   Tip: Add lime juice gradually and taste as you go—you can always add more lime, but you cannot remove it

6. 6

   Serve the broth

   • Ladle the finished broth into serving bowls.
   • If desired, garnish each bowl with a small handful of chopped fresh cilantro and a few thin slices of Thai red chili pepper.
   • Serve immediately while hot.
   • The broth can be enjoyed on its own as a light soup or used as a fragrant base for Thai curries, chicken soups, or rice noodle dishes.

   Tip: For extra flavor, reserve a few slices of cooked ginger and galangal to float in the bowl as garnish
