Recipe for Fish Soup from Brittany: La Cotriade

by | Sep 26, 2020 | Uncategorized

The saying goes that in Brittany, Bretons have a Celtic soul and a sailor’s heart. And that sailor’s heart is probably why they’re excellent fishermen and have wonderful seafood recipes. So here’s a traditional fish soup recipe from Brittany, called “Cotriade” to illustrate the point. It’s the Breton equivalent of a Bouillabaisse from Marseilles.


Traditional Cotriade, “Co-tree-odd” (or “kaoteriad” in the Breton Celtic language), is a recipe that dates back to the 1870s.

Traditionally, after a fishing expedition, each fisherman was offered a small percentage of the catch of the day, called the “godaille” or “cotriade,” to carry off in a small straw basket. Then he would often make a fish soup recipe from it.

Different versions

The version I had in my photo below was made from monkfish, sea bream, mussels, and vegetables like potatoes, broccoli & tomatoes.

And all the ingredients were swimming in a butter sauce with “Bouquet Garni”  herbs that the French do so well.

But you can use many other types of fish, (as you’ll see in the recipe below).

Preparation: 45 minutes. Cooking time: 30 minutes. 

Servings: 4 to 6


The fish :

  • 500 g / 1.1 lbs conger 
  • 300 g / 3/4 lb of sea bream 
  • 200 g/ 7 oz of hake 
  • 4 to 6 sardines 
  • 2 or 3 soles 
  • 1 or 2 mackerel 
  • 1 or 2 gurnard 
  • (Optional) mussels 

Other Ingredients: 

  • 1 kg/ 2.2 lbs of potatoes 
  • 2 onions 
  • 2 large tomatoes 
  • 200 g / 7 oz salted butter 
  • 1 garlic clove 
  • 1 bouquet garni 
  • 1 bunch of chervil 
  • Guérande salt or equivalent
  • Pepper 

The vinaigrette :

  • 6 tablespoons of oil 
  • 2 tablespoons of vinegar 
  • Parsley 
  • Chives


• Start by carefully scaling the fish and then washing them well. 

• Cut them into pieces of about 5 cm/2 inches. 

• Take a pot and brown your sliced ​​onions with the salted butter. 

• Then add your washed and peeled potatoes and stir them well in your butter and onion sauce. Add 3 L / 3 1/4 quarts of water. 

• Add to that your chopped garlic, the garnished bouquets and chervil, the peeled and seeded tomatoes, salt, and pepper. 

• When your potatoes are 3/4 cooked, it’s time to add your fish (conger, sea bream, and hake). 

• Let them cook for about ten minutes and add the other fish. 

• Cover again and cook for another 5 minutes after boiling again. 

• You can now prepare your vinaigrette – whisk together the ingredients. 

• Thoroughly drain the fish and potatoes. Filter your broth. 

• Serve everything in a dish and sprinkle your fish and potatoes with a little broth, according to your taste. Then sprinkle with the vinaigrette.  

Serving Tips

You can also serve the vinaigrette in a gravy boat, so everyone can season individually their potatoes and fish. Or when you prepare the plates, you can add a spoonful of the dressing to each plate.

Add some garlic croutons and a few mussels to decorate your dish for even more flavor. 

For a true Breton meal, accompany your dish with a glass of hard apple cider or white wine. 


Bretons truly have a Celtic soul and a sailor’s heart. Their culture is linked closely to the sea and they’re excellent fishermen.

Good food, especially seafood, is an important part of their heritage.

“Magit mat ho korf, hoc’h ene a chomo pelloc’h e-barzh.”
“Nourish your body well, and your soul will remain with you longer.” (Proverb in the Breton language)
