Canh Chua (Vietnamese Sweet and Sour Fish Soup)

Vietnamese canh chua is a bright sweet-and-sour soup, often served as part of a simple meal with steamed rice. Its character comes from a tamarind-sharpened broth softened by ripe pineapple and tomatoes, with fish sauce adding the savoury depth that keeps the fruitiness in check. Tender pieces of white fish cook gently in the hot broth, while bean sprouts, spring onion and coriander give the finished bowl freshness and crunch. Light but satisfying, it is the kind of soup that feels clean, fragrant and full of contrast without being heavy.

Why this recipe works

  • Bright, balanced broth: Tamarind brings the sour backbone, while pineapple, tomato and sugar soften the edges with gentle sweetness.
  • Savoury depth: Fish sauce seasons the broth with umami, giving the soup depth without needing a long simmer.
  • Fresh finish: Tender fish, juicy fruit, crisp bean sprouts and fresh herbs create a light but satisfying contrast.

Ingredient notes

  • Tamarind paste: Tamarind gives canh chua its distinctive sourness. Stir it in fully before adjusting seasoning so the broth tastes balanced rather than sharply acidic.
  • Choosing the fish: Use a mild white fish that holds together in broth. Firmer fillets are easier to handle and less likely to break apart.
  • Pineapple matters: Ripe pineapple adds sweetness and fruitiness to the broth; underripe pineapple will make the soup taste sharper.

Texture tips

  • Keep the fish tender: Once the fish is added, keep the soup at a gentle simmer and cook only until the pieces are opaque and flaking.
  • Add sprouts at the end: Bean sprouts need only a brief cook so they stay crisp and fresh against the hot broth.

Adjust the heat

  • For less heat: Use less chilli or remove the seeds before slicing.
  • For more heat: Add extra sliced chilli near the end so the heat stays bright and fresh.

Make-ahead tips

  • Store rice separately: Keep the jasmine rice separate from the soup so it does not absorb the broth and become soft.
  • Reheat gently: Warm the soup over low heat until piping hot, avoiding a hard boil so the fish stays in pieces.

  1. Rinse the jasmine rice in a colander until the water runs mostly clear. Tip into a saucepan with the measured water, bring to the boil, then cover and cook on the lowest heat for 12 minutes. Take off the heat and leave, covered, for 10 minutes.
  2. Meanwhile, cut the pineapple into bite-size chunks and cut the tomatoes into wedges. Thinly slice the red chilli, slice the spring onions, and roughly chop the coriander. Cut the fish into large bite-size pieces.
  3. Bring the measured water for the soup to a lively simmer in a stockpot. Whisk in the tamarind paste until dissolved, then stir in the fish sauce, salt and sugar. Taste the broth and adjust with a little more fish sauce for saltiness or sugar for balance if needed.
  4. Add the pineapple and simmer for 4 minutes, then add the tomatoes and sliced chilli and simmer for 3 minutes. Slide in the fish and cook gently for 3 to 5 minutes, just until opaque and flaking. Keep the heat moderate so the fish stays in pieces.
  5. Add the bean sprouts and cook for 1 minute so they stay crisp. Turn off the heat, then stir through most of the spring onion and coriander, reserving a little for the top. Ladle into bowls and serve with the steamed jasmine rice alongside.

Recipe notes

Tips

  • For a clearer broth, keep the soup at a gentle simmer once the fish goes in, and avoid stirring too much.
  • If serving anyone who is pregnant, elderly, or immunocompromised, make sure the fish is cooked until fully opaque and piping hot throughout.

Substitutions

  • Replace White fish fillet with Cod fillet for a firmer, flakier result.
  • Replace Pineapple with Mango for a softer, sweeter fruit note.
  • Replace Fresh coriander with Fresh mint for a different herbal finish.

Storage

  • Refrigerate up to 2 days
  • Cool the soup quickly, then refrigerate in a sealed container. Reheat gently in a saucepan over low heat until piping hot, taking care not to boil hard or the fish may break up; store rice separately and reheat with a splash of water.
