Ingredients
Method
- Preheat oven to 200°C / 180°C fan / Gas 6. Spread carrot, parsnip, swede, and sweet potato on a large tray — drizzle with 2 tbsp oil, season, toss. Roast 25–30 minutes until golden at edges, turning once.
- Heat remaining 1 tbsp oil in a large saucepan. Cook onion 8 minutes. Add leeks and celery — 5 minutes. Add garlic and thyme — 2 minutes.
- Add roasted vegetables to pan. Pour in hot stock. Add bay leaf — season. Simmer gently 20–25 minutes until all vegetables completely tender.
- Remove bay leaf. Roughly mash about one-third of the vegetables with a potato masher for a partly thick, partly chunky texture. Or blend smooth. Or leave chunky.
- Stir in fresh parsley. Taste — season very assertively. Serve in deep bowls with cream swirl if using and crusty bread.
Notes
Roast the root vegetables first — gives caramelised sweetness and depth that boiling alone cannot.
Use hot stock — brings the soup to temperature quickly and starts cooking immediately.
Roughly mash a third of the vegetables — gives the best texture: partly thick, partly chunky.
Season assertively at the end — vegetable soup is frequently under-seasoned and it matters.
Make a big batch and freeze — this soup freezes perfectly for up to 3 months.
