Equipment
Instructions
1. Prepare the vegetables
- Peel and wash the carrots, celery, leeks, and potatoes. Chop them into large, rustic pieces. Finely slice the onion. Set aside.
2. Sauté the onion
- Melt the butter in a large pot or cocotte over medium heat. Add the sliced onion and sauté until translucent and fragrant, about 5 minutes.
3. Deglaze with wine and add stock
- Pour in the white wine and bring to a boil. Allow the wine to reduce slightly, then add the fish stock or fumet. Bring to a gentle simmer.
4. Cook the vegetables and bouquet garni
- Add the bouquet garni and all the prepared vegetables (carrots, celery, leeks, potatoes) to the pot. Season with salt and pepper. Let everything simmer, uncovered, at a gentle boil for about 25 minutes, or until the vegetables are tender but not mushy.
5. Add the fish and prawns
- Cut the fish into large, even chunks. Gently add them to the pot and simmer for 8–10 minutes, until the fish is just cooked through and opaque. Stir in the crème fraîche or double cream, then add the cooked prawns and heat through for another 2 minutes.
6. Finish and serve
- Remove the bouquet garni. Taste and adjust seasoning if needed. Sprinkle with chopped parsley just before serving. Serve hot in deep bowls, with crusty bread on the side.

- Serving suggestion: Accompany with a crisp green salad and a chilled glass of white wine.
About this recipe
The first time I ate pot au feu de la mer, I had no idea what was coming. My neighbour had invited us for dinner and as she’s a great cook, I’m always excited to taste what she made. I knew pot-au-feu already, the slow-cooked beef version I grew up with before I became pescatarian, and I make the vegetable version at home regularly in winter. But when she brought out this seafood soup, I just stopped. It smelled like the sea but also like cosiness and warmth, which is a combination I wasn’t expecting. I asked her for the recipe before we’d finished eating. That’s how good it was.
Where pot-au-feu comes from
Pot-au-feu literally means pot on the fire. It’s one of the oldest dishes in French cooking: a big pot of meat and root vegetables simmered slowly in broth until everything is tender and the liquid has become something really special. It’s less a single recipe and more a way of thinking. Use what you have, cook it gently, and make sure everyone at the table is properly fed.
The classic version is made with beef and marrow bones. But France has as many identities as it has regions, and each one has adapted the pot-au-feu idea to fit its own landscape. In Alsace, the bouillon becomes the base for a second course with liver dumplings. In the southwest, garbure takes the same spirit and swaps the beef for duck confit and white beans. Along the Normandy coast, where the sea has always been the main pantry, cooks simply replaced the beef with whatever the boats brought in that morning. That’s pot-au-feu de la mer, and I’d argue it’s the most elegant of all the regional versions.
The Norman coastline and its seafood
Normandy isn’t talked about as a seafood region the way Brittany is, which is a bit unfair. The coastline runs from the Seine estuary all the way to the bay of Mont-Saint-Michel, and ports like Dieppe, Fécamp, and Honfleur have been landing fish for centuries. Normandy also gave France its template for cooking fish with cream and white wine, a combination that sums up the region’s cooking just as clearly as its butter and its calvados.
This seafood soup sits in that tradition. The base is a proper fish stock, reduced with dry white wine and finished with crème fraîche. A pinch of saffron gives the broth its golden colour and a depth you really can’t get any other way. The vegetables are cut big and rustic, the way pot-au-feu vegetables always are. The fish, salmon, monkfish, haddock, cod, plus king prawns, goes in at the end and is cooked gently so it stays tender rather than falling apart.
What to make this seafood soup in
Nathalie used the same dish I would have used: a cast iron cocotte. I haven’t met anyone in France who doesn’t own one. It’s a classic for good reasons, you can use it for almost every recipe and it actually makes the food taste better. For this soup you want something that spreads heat evenly, keeps a gentle simmer, and can go from stove to table looking good. Bring the pot over and ladle the soup out at the table, with crusty baguette and a crisp glass of white wine.
How to eat pot au feu de la mer
In Normandy this is a proper main course, generous and complete. It doesn’t need anything more than bread and maybe a bit of cheese afterwards. It reheats really well the next day too, when the broth has had time to deepen even more. Nathalie served it with a chicory salad and a sharp mustard vinaigrette, which cut through the richness of the crème fraîche perfectly. That combination is worth stealing.
If you’re making it for a dinner party, bring the cocotte straight to the table and let everyone help themselves. That’s the spirit of pot-au-feu de la mer.
