This elegant smoked haddock soup is a sophisticated take on classic coastal flavours, pairing the delicate saltiness of the fish with the subtle aniseed notes of fresh fennel. Infused with a fragrant herb bundle of rosemary, thyme and bay, the double cream base is simmered until rich and velvety. It is a wonderfully comforting dish that celebrates high-quality seafood while remaining simple enough for a midweek treat.
As a high-protein option, this soup is both satisfying and nutritious, making it an excellent choice for a filling lunch or a refined starter for a dinner party. If you cannot find smoked haddock, naturally smoked cod or mackerel make brilliant alternatives. Serve with a slice of crusty sourdough to soak up every drop of the savoury, herb-scented broth.

How to make Smoked Haddock Soup
Back to contentsWrap the rosemary, thyme, bay leaves, and peppercorns in the cheesecloth and secure with the kitchen string. Set aside.
In a medium saucepan over moderate heat, melt the butter. Add the leeks and fennel and sauté, stirring occasionally, until softened, 8 to 10 minutes. Add the double cream and bring to a boil. Reduce heat to low, add the herb package, and simmer until the soup is reduced by about one third, 20 to 25 minutes. Add haddock, cover, and simmer an additional 5 minutes. Season to taste. Divide soup among 8 bowls, making sure to evenly distribute the fish and vegetables. Sprinkle each dish with dill and serve immediately.
