Ingredients
- 400g/14oz sweet potatoes (pink-fleshed variety), cut into small bite-size pieces
- 225g/8oz peeled butternut squash, cut into 1cm/1/2in slices
- 50g/2oz/1/4 cup butter
- 1 onion, chopped
- 450g/1lb Finnan haddock fillets, skinned
- 300ml/1/2 pint/1 1/4 cups water
- 600ml/1 pint/2 1/2 cups milk
- Small handful of Thai basil leaves
- 60ml/4 tbsp double cream
- Salt and ground black pepper
Instructions
- Cook the sweet potatoes and butternut squash separately in boiling salted water for 15 minutes or until just tender. Drain both well.
- Meanwhile, melt half the butter in a large, heavy-based saucepan. Add the onion and cook for 4-5 minutes, until softened but not browned. Add the haddock fillets and water.
- Bring to the boil, reduce the heat and simmer for 10 minutes, until the fish is cooked. Use a draining spoon to lift the fish out of the pan and leave to cool. Set the cooking liquid aside.
- When cool enough to handle, carefully break the flesh into large flakes, discarding the skin and bones. Set the fish aside.
- Press the sweet potatoes through a sieve and beat in the remaining butter with seasoning to taste. Strain the reserved fish cooking liquid and return it to the rinsed-out pan, then whisk in the sweet potato. Stir in the milk and bring to the boil. Simmer for about 2-3 minutes.
- Stir in the butternut squash, fish, Thai basil leaves and cream. Season the soup to taste and heat through without boiling. Ladle the soup into six warmed soup bowls and serve immediately.

Chef’s Pro Tips for Success
Prepping your Finnan haddock perfectly is the first step to a spectacular chowder. For me, a razor-sharp, flexible fillet knife is non-negotiable. This high-carbon steel fillet knife glides along the skin, making it effortless to remove and helping you to separate perfect, large flakes without mangling the delicate flesh. A clean prep is the foundation of a clean-tasting soup.
