• 300 gr king prawns

Additional ingredients

• 800 gr firm-fleshed potatoes
• 4 carrot
• 2 celery
• 3 leek
• 1 onion
• 1 bouquet garni thyme, bay leaf, parsley stalks, tied together
• 300 ml dry white wine
• 1.5 l fish stock or fumet
• 30 gr unsalted butter
• 3 tbsp crème fraîche
• 20 gr flat-leaf parsley a handful
• 1 pinch saffron threads for extra aroma
• salt and black pepper

Equipment

1 dutch oven

1 wooden spoon

1 measuring jug

1 knife

1 chopping board

1 ladle

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.

Notes

• For extra flavour: Infuse the broth with a pinch of saffron for a golden hue and delicate aroma.
• Make ahead: This dish reheats beautifully, making it ideal for entertaining or meal prep.
• Vegetable options: You can add fennel or turnip for extra depth.
• 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 what started with a simple “come over for dinner” somehow became the whole night, as usual. I knew pot-au-feu already, the slow-cooked beef version I grew up with, and I know and make the vegetable pot-au-feu regularly at home. So when she brought out this seafood soup, I just stopped. It smelled like the sea and like a French kitchen at the same time, which sounds wrong on paper but works incredibly well in real life.

I asked her for the recipe before we had finished eating. That is how good it was.

What pot-au-feu actually means

Pot-au-feu literally means pot on the fire. It is one of the oldest, most basic dishes in French cooking: a big pot of (meat and) root vegetables simmered slowly in broth until everything is tender and the liquid has turned into something heavenly. It is 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 is a country with as many identities as there are regions, and each one has bent the pot-au-feu idea to fit its own landscape and ingredients. In Alsace, the bouillon becomes the base for a second course with liver dumplings. In the southwest, garbure takes the spirit of pot-au-feu 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 to make this seafood soup.

That is pot-au-feu de la mer, the seafood version, and I would argue it is the most elegant of all the regional takes.

The Norman coastline and its seafood

Normandy is not primarily known as a seafood region the way Brittany is, but that undersells it considerably. The Norman coast runs from the Seine estuary to the Mont-Saint-Michel bay, and the ports of Dieppe, Fécamp, and Honfleur have been landing fish for centuries. Normandy gave France its model for cooking fish in cream and white wine, the combination that defines the region’s cuisine as distinctly as its butter and its calvados.

Normandy is not talked about as a seafood region in the same breath as Brittany, 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 like this blanquette de poisson for example. It’s a combination that sums up the region’s cooking just as clearly as its butter and its calvados.

This French seafood soup sits squarely in that tradition. The base is a proper fish stock, reduced a little with dry white wine and finished with crème fraîche. A pinch of saffron gives the broth its golden colour and a depth you cannot really fake 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 instead of breaking apart.

What you get is a seafood soup that somehow feels both light and deeply satisfying. A true french seafood soup that feels like something special without being complicated.

The right pot matters

For a dish like this, the pot does makes a difference. You want something that spreads heat evenly, keeps a gentle simmer, and can go from stove to table without looking out of place. I use my Staub cast iron cocotte for this. The enamel inside means there is no metallic taste in the broth, the heavy lid keeps the temperature steady, and it is pretty enough that you can serve straight from it at the table, which is exactly how this dish should arrive. Bring the pot over and ladle the soup out at the table, with baguette or any good crusty bread alongside.

How the French eat this seafood soup

In Normandy this is a real main course, generous and complete, and it does not need anything more than bread and maybe a bit of cheese afterward. It reheats beautifully the next day, when the broth has had time to deepen even more. My neighbour served it with a chicorey salad and a sharp mustard vinaigrette, which cut through the richness of the crème fraîche perfectly.

If you make it for a dinner party, bring the cocotte straight to the table and let everyone help themselves. That is the spirit of pot-au-feu de la mer: generous, relaxed, and completely centred on the pleasure of eating together.
