Clam and Cod Chowder

This hearty clam and cod chowder is a sophisticated take on a coastal classic, offering a rich and velvety texture without the need for flour-based thickeners. By allowing the potatoes to gently break down during a long simmer, the starch creates a naturally creamy body that perfectly complements the delicate flavours of the sea. The combination of fresh littleneck clams and flaky white fish makes this a standout high-protein meal that feels both indulgent and nourishing.

Ideal for a weekend lunch or a comforting midweek supper, this one-pot seafood dish is best served with crusty sourdough bread to soak up every drop of the savoury broth. The addition of fresh thyme and a squeeze of bright lemon juice balances the richness of the double cream, while a dash of hot sauce adds a subtle, warming kick. It is a wonderful way to enjoy high-quality British seafood in a format the whole family will love.

Ingredients for Clam and Cod Chowder

  • 2 tablespoons olive oil

  • 2 tablespoons unsalted butter

  • 675g small Yukon Gold potatoes, peeled, halved, quartered if large

  • 2 large leeks, white and pale-green parts only, finely chopped

  • 4 celery stalks, finely chopped

  • 4 sprigs thyme, plus leaves for serving

  • Kosher salt, freshly ground pepper

  • 80ml dry white wine

  • 950ml fish stock or bottled clam juice

  • 475ml double cream

  • 1.8kg littleneck clams, scrubbed

  • 900g skinless cod or haddock, cut into large pieces Hot sauce and lemon wedges (for serving)

Heat oil and butter in a large heavy pot over medium. Add potatoes, leeks, celery, and thyme sprigs; season with salt and pepper. Cook, stirring occasionally, until leeks are tender, about 5 minutes. Add wine, bring to a boil, and cook until reduced by half, about 2 minutes. Add stock and cream, season with salt and pepper, and bring to a gentle simmer (if using clam juice, taste before adding salt, it's very briny). Cook until potatoes are starting to fall apart (their starch will help give body to the soup), 50-60 minutes.

Add clams to pot and stir to coat. Cover and simmer until clams are just beginning to open, 10-12 minutes. Season cod with salt and pepper and add to pot. Reduce heat to low and cover. Let fish gently poach until cooked through, about 5 minutes (simmering too hard can make fish tough). Season with salt and pepper, if needed, and serve topped with thyme leaves, with hot sauce and lemon wedges.
