Slow-cooked Root Vegetable Soup

3 hours

Serves 6

This recipe is from Delia's Complete How to Cook, The Delia Collection: Soup.

Something happens to vegetables when they're cooked very slowly for a long time: their flavour becomes mellow but at the same time more intense, and your kitchen is filled with aromas of goodness.

This soup is also completely fat-free.

Method

There's not much to do here once everything is peeled and chopped.

All you do is place everything in the casserole and bring it up to a gentle simmer, then put the lid on, place it in the lowest part of the oven and leave it there for 3 hours, by which time the vegetables will be meltingly tender.

Next remove the bay leaves and process or liquidise the soup in several batches to a purée, then gently re-heat, and serve the soup in bowls with a teaspoon of Greek yoghurt swirled into each and garnished with the fresh chives.
