Psarosoupa (Greek Fish Soup with Lemon and Vegetables)

Psarosoupa brings the clean, lemony character of Greek home cooking to a simple fish soup made for gentle simmering rather than heavy richness. The dish centres on tender white fish, potatoes, carrot and celery in a clear, savoury broth, with bay leaves for quiet aroma and extra virgin olive oil for body. Lemon is added at the end so the soup stays bright and fresh, while parsley and black pepper sharpen the finish. Light but satisfying, it works well as an easy dinner when you want something nourishing, delicate and not too heavy.

Why this recipe works

  • Gentle simmering: Cooking the fish softly in the broth keeps it tender while preserving a clear, delicate soup base.
  • Bright, balanced finish: Lemon juice cuts through the olive oil and potatoes, giving the soup its fresh, recognisable Greek character.
  • Simple one-pot method: The vegetables build the broth first, then the fish cooks quickly at the end, keeping the process streamlined.

Ingredient notes

  • Choose firm white fish: A firm, skinless and boneless white fish fillet is easiest to poach and less likely to fall apart in the broth.
  • Cut vegetables evenly: Similar-sized pieces of potato, carrot and celery cook at the same rate and make the soup easier to eat.
  • Add lemon off the heat: Stirring in the lemon after cooking keeps the flavour clean and fresh rather than sharp or dulled.

Texture tips

  • Keep the fish tender: Once the fish is added, maintain only a very gentle simmer; vigorous boiling can toughen the fish and break it up.
  • Add fish near the end: Wait until the potatoes are just tender before adding the fish, as the fillet needs only a short cook in the hot broth.

Make-ahead tips

  • Best served fresh: The soup is at its best soon after the fish is cooked, when the broth is clear and the fillet is still delicate.
  • Prep vegetables ahead: The onion, carrot and celery can be sliced and chopped in advance to shorten the cooking time later.
  • Reheat gently: Warm leftovers over low heat until piping hot, avoiding a hard boil so the fish stays tender.

Authenticity notes

  • Greek home-style soup: Psarosoupa is typically simple and broth-led, built around fish, vegetables, lemon and good olive oil rather than heavy cream.
  • Lemon and olive oil matter: The final lemon juice and extra virgin olive oil are key to the soup’s light richness and bright Mediterranean flavour.

  1. Halve and thinly slice the yellow onion. Peel the carrot and russet potato, then cut the carrot, celery and potato into bite-sized pieces.
  2. Set a stockpot over medium heat and warm the extra virgin olive oil. Add the onion with a pinch of the fine sea salt and cook for 5 minutes until softened but not coloured.
  3. Add the carrot, celery and potato, then stir for 1 minute to coat in the oil. Add 1.2 l water and the bay leaves, then bring to a gentle simmer.
  4. Simmer for 18 to 22 minutes, stirring occasionally, until the potatoes are just tender. Keep the heat low enough that the soup bubbles gently.
  5. Season the broth with the remaining fine sea salt. Nestle in the white fish fillet, keeping the simmer very gentle, and cook for 6 to 8 minutes until the fish is opaque and flakes easily.
  6. Finely chop the fresh parsley. Squeeze the lemon and stir the juice into the soup off the heat, then add the black pepper and parsley.
  7. Taste and adjust with a little more lemon juice or black pepper if you like. Ladle into bowls and finish each serving with a small drizzle of extra virgin olive oil.

Recipe notes

Tips

  • Keep the simmer very gentle once the fish goes in, as a hard boil can break it up and cloud the broth.
  • For the cleanest flavour, skim off any foam that rises in the first few minutes of simmering.
  • If serving to pregnant people, young children, older adults, or anyone immunocompromised, make sure the fish is cooked until fully opaque and flakes easily.

Substitutions

  • Replace the white fish fillet with salmon for a richer soup.
  • Replace fresh parsley with fresh dill for a more herb-forward finish.
  • Replace lemon with lime for a slightly sharper citrus note.

Storage

  • Refrigerate up to 2 days
  • Cool quickly, then refrigerate in a sealed container. Reheat gently in a saucepan over low heat until piping hot, avoiding a hard boil so the fish stays tender.
