2 kilogram celeriac, coarsely chopped
1 brown onion, coarsely chopped
3 clove garlic, quartered
1 celery stick, trimmed, coarsely chopped
6 cup (1.5l) water
4 cup (1l) chicken or vegetable stock
1/2 cup (125ml) pouring cream
2 tablespoon lemon juice
1/3 cup loosely packed fresh chervil leaves
1 tablespoon extra virgin olive oil
Silky smooth and deeply nourishing, this cream of celeriac soup is lifted by lemon and chervil and finished with a drizzle of olive oil.
Combine celeriac, onion, garlic, celery, the water and stock in a 4.5-litre (18-cup) slow cooker. Cook, covered, on low, about 8 hours.
Stand soup 10 minutes, then blend or process, in batches, until smooth. Return soup to cooker; stir in cream. Cook, covered, on high, until hot; season to taste.
Serve soup sprinkled with chervil; drizzle with oil.
Be careful when blending or processing hot soup – don’t over-fill the container (one-third to half-full as a guide), and make sure that the lid is secure.
