Tom Yum Goong — Thai Spicy Prawn Soup
Thailand's iconic hot and sour prawn soup — a fragrant, fiery broth of lemongrass, galangal, kaffir lime and fresh chillies with plump prawns and mushrooms.
About This Recipe
Tom Yum Goong (ต้มยำกุ้ง) is Thailand's most famous soup and one of the world's great aromatic broths. The name literally means 'boiling spicy and sour' — and it delivers on both counts with lemongrass, galangal, kaffir lime leaves and fresh bird's eye chillies creating a broth so complex and vivid that it's simultaneously warming, cooling, spicy, sour and deeply savoury.
Ingredients
Serves 4
- 500 graw prawns(shell on or peeled)
- 1.2 litreschicken or prawn stock
- 3 stalkslemongrass(bruised and cut into 4cm pieces)

Instructions
- 1
Build the aromatic broth
Bring stock to a boil. Add lemongrass, galangal, kaffir lime leaves and chillies. Simmer 5 minutes to infuse the broth with aromatics.
Bruise the lemongrass and galangal — bash them with the flat of a knife. This releases the essential oils into the broth.

Add mushrooms and nam prik pao
Add mushrooms and roasted chilli paste (if using). Simmer 3 minutes.

Cook the prawns
Add prawns. Cook just 2–3 minutes until pink and curled. Remove from heat immediately — overcooked prawns turn rubbery.

Season
Season with fish sauce and lime juice. Taste: it should be hot, sour, salty and slightly sweet — adjust the balance. Tom yum's defining characteristic is the bold contrast between hot chilli and sour lime.

Serve
Ladle into bowls with coriander. The aromatic solids (lemongrass, galangal, lime leaves) are not eaten — they are flavouring only.
Pro Tips
- →
Fresh galangal and kaffir lime leaves are non-negotiable. Dried are significantly inferior.
- →
For Tom Yum Nam Khon (creamy): add 4 tbsp coconut milk at the end for the milky version.
- →
Bird's eye chillies are very hot — reduce to 2–3 for a milder soup, keep all 6 for authentic heat.
Variations
- •
Tom Yum Gai: use chicken strips instead of prawns.
- •
Tom Yum Nam Khon: the creamy version with coconut milk — popular outside Thailand.
- •
Tom Kha Gai: replace galangal with more galangal, add coconut milk — the creamy sister soup.
Storage
Best eaten fresh. Broth keeps 3 days refrigerated — add fresh prawns when reheating.
History & Origin
Tom Yum has been recorded in Thai royal cuisine records for centuries. It became internationally famous after being shortlisted among the world's greatest soups by international food surveys. Thailand's national soup, along with Pad Thai, represents Thai flavour philosophy: always balance hot (spicy), sour, salty and sweet.
Frequently Asked Questions
What if I can't find galangal?
Fresh ginger is a partial substitute but the flavour is quite different — galangal is more piney, less sharp. Thai and Asian supermarkets stock fresh and frozen galangal year-round.
