Method
Soup base & aromatics
- 1
- 2
Add the sliced galangal (or ginger), smashed and sliced lemongrass, and sliced fresh red chilies. Stir and cook 1 minute to release aromas.
Broth & seasonings
- 3
Pour in the chicken or vegetable stock and bring to a gentle simmer. Lower heat to maintain a simmer and let the aromatics infuse the broth for 6–8 minutes.
- 4
Add the fish sauce, rice vinegar, palm or brown sugar, and white pepper. Stir to dissolve the sugar and taste — the soup should be a balance of hot, sour, and salty. Adjust: more fish sauce for salt, more lime later for sour, more sugar to round it.
Proteins & vegetables
- 5
Add the thinly sliced chicken to the simmering broth. Stir gently and simmer until the chicken is cooked through, about 4–6 minutes depending on slice thickness.
- 6
Add the sliced mushrooms, tomato wedges, and baby corn (if using). Simmer another 2–3 minutes until vegetables are tender but still bright.
Finish & herbs
- 7
Turn off the heat. Stir in the fresh lime juice and taste, adjusting for brightness and heat — add more lime juice for sourness or a little more fish sauce if needed.

Serve
Ladle the hot and sour basil soup into bowls. Garnish with extra basil leaves, cilantro, additional sliced chilies or a drizzle of chili oil if you like it spicier, and serve with lime wedges at the side.
