Thai Soup
A Thai-inspired tom kha-style chicken soup with coconut milk, lemongrass, galangal and lime
A Thai-inspired tom kha-style chicken soup with coconut milk, lemongrass, galangal and lime. The catalogue label is broad; this is specifically a coconut chicken version, not every Thai soup.
Plan about 39 minutes including 15 minutes preparation, 24 minutes cooking and 0 minutes of separate resting or chilling. Cooking times are ranges: ingredient thickness, pan width and burner strength alter the endpoint. Preparation is counted separately rather than assuming every task overlaps. One tablespoon = 15 ml; one teaspoon = 5 ml.
About Thai Soup
A Thai-inspired tom kha-style chicken soup with coconut milk, lemongrass, galangal and lime. The catalogue label is broad; this is specifically a coconut chicken version, not every Thai soup.
Lime juice goes in off heat to retain its sharp aroma. Galangal and ginger are not identical: ginger makes a usable adaptation with a different flavour.
Kitchen testing has not been documented for this recipe. Cooking times are estimates and vary with the stove, cookware and batch size. Follow the doneness checks in the method.
Make it work for your kitchen
Original quantities serve 4. Cooking times, pan size and frying-oil depth do not scale, cook in extra batches instead.
Before you start
Prepare the batch
Prepare the ingredient cuts listed below and complete the first method stage before moving on. Trim lemongrass to its tender lower section, bruise with the back of a knife and cut into large identifiable pieces.
Mise en placeControl liquid and salt
Keep each separately labelled liquid quantity distinct: dough water, cooking liquid, soaking water and top-up allowances serve different purposes. Do not add an allowance automatically.
Batch controlSet up the equipment
Have the following tools ready before starting: Digital kitchen scale and measuring jug; Sharp knife and stable chopping board; Heavy saucepan or pan sized to the batch; Wooden spoon or heatproof spatula.
Clean workspaceMeasure the ingredients
Measure the ingredient quantities for your selected servings before applying heat. Keep separately listed groups, such as dough, filling, sauce or garnish, in separate containers; keep any optional additions separate.

Step-by-step cooking method
1 Prepare aromatic pieces
Trim lemongrass to its tender lower section, bruise with the back of a knife and cut into large identifiable pieces.
2 Prepare aromatic pieces (continued)
Slice galangal thinly. These tough aromatics flavour the soup but are not intended to be eaten.
3 Infuse
Put stock, galangal, lemongrass, lime leaves and chilli in a saucepan. Bring to a simmer and cook gently 8–10 minutes, covered partly.
4 Poach chicken
Add chicken slices and mushrooms. Simmer 6–8 minutes, separating chicken with a spoon. Check a thick piece reaches 74°C.
5 Add coconut milk
Stir in coconut milk, fish sauce and sugar.
6 Add coconut milk (continued)
Heat gently 3–4 minutes without a furious boil. Use measured water if the soup is too concentrated; it should remain fluid.
7 Finish with lime
Remove from heat and stir in lime juice.
8 Finish with lime (continued)
Taste before adding any more fish sauce, then add coriander. Remove tough aromatics before serving or clearly tell diners to leave them aside.
Chef’s tips
- Lime juice goes in off heat to retain its sharp aroma. Galangal and ginger are not identical: ginger makes a usable adaptation with a different flavour.
Common mistakes & quick fixes
- The mixture catches at the bottom.
- Lower the heat and stir along the base. If food has scorched, transfer the unburnt portion to a clean pan without scraping the burnt layer into it.
- The final texture is too thick.
- Add the listed top-up liquid in small increments, let it heat through, and check seasoning again. If there is no top-up allowance, use the texture correction specified in the steps.

Helpful answers before you cook
Can I eat the lemongrass pieces?
They and galangal slices are tough aromatics; remove before serving or clearly leave aside.
Why add lime off heat?
Its sharp fresh aroma fades during long boiling.
Can ginger replace galangal exactly?
It makes a usable but differently flavoured adaptation, not an identical substitute.
