Serves 435 minutes~£1.20/bowl

The soup we make when the week's been too long — everything softens together in one pot and the kitchen feels sorted again. Bread for dunking is non-negotiable.

Soft, sweet leeks melted into buttery potatoes — the soup that tastes like it took all afternoon and didn't. Croutons or good bread alongside.

Ingredients

  • 3 medium leeks, washed and sliced
  • 500g floury potatoes (Maris Piper), cubed
  • 1 onion, chopped
  • 40g butter
  • 1 litre vegetable stock
  • 100ml milk or single cream (optional)
  • Salt & white pepper

Method

  1. Melt the butter in a large pot over a low heat. Add the leeks and onion with a pinch of salt and sweat gently for 10 minutes, lid on, until soft but not coloured.
  2. Add the potatoes and stock. Bring to a simmer and cook 15–18 minutes, until the potatoes collapse at a fork's touch.
  3. Blend until smooth (or leave a little texture if you prefer). Stir in the milk or cream if using, season well, and warm through without boiling.
