Bouillabaisse Marseillaise

Fragrant with saffron, fennel and garlic, Bouillabaisse Marseillaise is the Provençal fish soup most closely associated with Marseille. Its character comes from a deeply savoury fish broth enriched with tomatoes, leeks and aromatic vegetables, then finished with tender chunks of white fish and prawns cooked gently so they stay delicate. The bowl should be bright, briny and lightly herbal rather than heavy. Toasted baguette spread with garlicky rouille is essential for serving, adding heat, richness and crunch, while lemon lifts the broth just before eating.

Why this recipe works

  • Layered broth: Softened fennel, leek, garlic and tomatoes build a fragrant base before the saffron and fish stock are added.
  • Gentle seafood cooking: The fish and prawns go in only at the end, keeping them tender and helping the broth stay clear.
  • Bright finish: Tomatoes and lemon lift the savoury fish stock, while the rouille toasts add richness, garlic and gentle heat.

Authenticity notes

  • Marseille-style base: Bouillabaisse is closely associated with Marseille and the Provençal coast; this version keeps the saffron, fennel, tomato and seafood profile central.
  • Rouille toasts: Garlicky rouille on toasted bread is the classic accompaniment, adding body and spice as it softens into the broth.
  • Accessible seafood: Using white fish fillets and prawns makes the dish practical for everyday shopping while preserving the essential seafood character.

Ingredient notes

  • Choose firm white fish: Firm fillets hold their shape better in the hot broth; very delicate fish can break apart before serving.
  • Use saffron carefully: Saffron gives the broth its distinctive colour and aroma, so let it infuse during the simmer rather than adding it at the end.
  • Finish with lemon: Add lemon at the table or just before eating so the broth tastes fresh rather than sharply cooked.

Timing notes

  • Most of the time builds the broth: The vegetables, tomatoes, saffron and stock need time to develop flavour; the seafood itself cooks quickly at the end.
  • Best served promptly: Serve once the prawns are pink and the fish flakes easily, as seafood can toughen if held too long in hot broth.

Make-ahead tips

  • Make the broth ahead: The broth can be prepared in advance and chilled; add the fish and prawns only when reheating to serve.
  • Reheat gently: Warm the soup over low heat until piping hot, avoiding a hard boil so the fish stays intact.
  • Toast fresh bread: The bouillabaisse can be stored briefly, but the baguette toasts are best made fresh so they stay crisp under the rouille.

  1. Trim the fennel and slice it thinly, reserving any feathery fronds for serving if you like. Trim and wash the leeks well, then slice. Peel the garlic; finely chop 4 cloves for the soup and keep 1 clove for the rouille.
  2. Heat the olive oil in a large pot over medium heat. Add the fennel and leeks with a pinch of salt and cook for 10 minutes, stirring, until softened but not browned. Stir in the chopped garlic and cook for 1 minute until fragrant.
  3. Roughly chop the tomatoes and add them to the pot. Cook for 8 to 10 minutes until they collapse and look jammy. Stir in the saffron threads.
  4. Pour in the fish stock and bring to a gentle boil, then reduce to a steady simmer. Simmer for 25 minutes so the broth takes on the saffron and fennel flavour. Taste and season with a little more salt if needed.
  5. While the broth simmers, toast the baguette slices until golden. In a small bowl, mix the mayonnaise with the remaining garlic clove (finely grated or crushed) and the cayenne pepper. Spread the rouille on the warm toasts.
  6. Cut the white fish into generous chunks. Add the fish to the simmering broth and cook for 3 minutes, then add the prawns and cook for 2 to 4 minutes more, until the prawns are pink and the fish flakes easily. Keep the soup at a gentle simmer so the fish stays tender.
  7. Cut the lemon into wedges. Ladle the soup into bowls and serve with the rouille toasts. Squeeze lemon over each bowl just before eating.

Tips

  • Keep the broth at a gentle simmer once the fish goes in; a hard boil can break the fish up and make the soup cloudy.
  • If serving to pregnant people, young children, older adults, or anyone immunocompromised, make sure the prawns are cooked through and the soup is piping hot.

Substitutions

  • Replace the baguette with crusty white bread for the toasts.
  • Replace the mayonnaise with aioli for a more intensely garlicky rouille.

Storage

  • Refrigerate up to 2 days
  • Cool quickly and refrigerate in an airtight container. Reheat gently in a saucepan over low heat until piping hot, taking care not to boil hard or the fish may break up; toast fresh bread for serving.
