Gordon Ramsay Fish Soup Recipe 

Gordon Ramsay’s fish soup is a classic Provençal soupe de poissons made with a mix of small fish, saffron, fennel, Cognac, and tomatoes, pureed until smooth and served with rouille croutons and melted Gruyère. It takes about an hour from cutting board to table.

This recipe appears as “Soupe de Poissons Provençale” in Gordon Ramsay’s Passion for Flavour, where he describes it as “a fisherman’s soup, so eat it with gusto.” He stresses that “the secret of this soup is to use as many different fish as you can find,” because blending several varieties creates a depth no single fish can match.

The technique that separates this from weaker versions: he fries the fish pieces golden in a separate pan before they go anywhere near the broth. That browning builds a layer of roasted flavour that simmering alone can’t produce, and it’s why the finished soup tastes rich without any cream.

FAQs

Why does Ramsay fry the fish separately before adding it to the soup?

Most home fish soup recipes dump raw fish straight into a simmering broth. Ramsay fries his pieces in a separate pan for about 7 minutes until they’re golden all over.

That browning creates roasted, caramelised notes on the surface of the fish through the Maillard reaction. Those flavours dissolve into the broth during the simmer and give the finished soup a depth that raw-simmered fish simply can’t deliver. It’s the same reason you brown meat before making a stew.

Why does he reduce the Cognac and wine down to almost nothing before adding water?

After the fish goes into the aromatics, Ramsay adds Cognac first, lets it reduce, then adds white wine and simmers it down to just one tablespoon of liquid. Only then does the water go in.

This forces all the alcohol to cook off while concentrating the flavour compounds from both the Cognac and wine into a tiny, intense base. If you added the water at the same time, those flavours would be diluted from the start and you’d never get them back. Ramsay’s seafood bisque uses a similar reduction technique with brandy for the same reason.

Why leave the bones in the fish?

Ramsay specifically says to remove only the eyes and gills, keeping everything else intact including the bones. The eyes and gills make soup taste bitter, but the bones do the opposite.

Fish bones release gelatine as they simmer, which gives the soup body and a slightly silky mouthfeel even without cream. Since everything gets pureed and strained through a fine sieve, no bone fragments end up in the finished bowl.

Why does he strain the soup twice?

After pureeing the fish and vegetables, Ramsay pushes the mixture through a fine sieve with the back of a ladle. This is on top of the initial straining through a colander.

The double straining removes every trace of bone, scale, and fibre. What you’re left with is completely smooth, almost like a bisque. A single pass through a colander would leave the soup grainy and rough. That extra five minutes of sieving is the difference between a rustic potage and a refined Provençal classic.

What fish should you use if you can’t find Mediterranean varieties?

Ramsay lists wrasse, rockfish, gurnard, rascasse, conger eel, John Dory, monkfish, and dorade. Most of those are hard to find outside European fish markets. The principle matters more than the exact species: use a mix of at least three different fish.

Red snapper, sea bass, porgy, and monkfish tail are widely available and work well. Avoid oily fish like mackerel or salmon because their strong flavour will overpower the saffron and fennel. Ask your fishmonger for whatever white-fleshed fish scraps or fillets they have going cheap, heads on if possible, and you’ll be close to what Ramsay intends.

What is rouille and can you buy it?

Rouille is a thick, garlicky paste from southern France traditionally made with roasted red peppers, garlic, breadcrumbs or potato, olive oil, and sometimes saffron or cayenne. It’s the classic accompaniment to Provençal fish soups and bouillabaisse.

You can find jarred rouille at specialty stores, but it’s simple enough to make at home by blending roasted red peppers with raw garlic, soaked bread, olive oil, and a pinch of cayenne until smooth. Spread it on the croutons before floating them so it melts into the hot soup. If you enjoy that garlic-forward kick, Ramsay’s lobster bisque pairs well with a similar rouille on the side.
