step 1
Finely dice the onion
step 2
Chop the parsnip and carrot into small chunks
step 3
Melt the butter in a saucepan with a little olive oil (to stop the butter burning)
step 4
Sweat the onion for 10 mins over a low heat. Do not let the onion brown. It should take on a translucent look
step 5
Add the chopped parsnips and carrot
step 6
Pour on the vegetable stock (or water and 2 knorr cubes)
step 7
Bring to the boil and leave to simmer for 30 mins.
step 8
When the parsnips and carrots are completely soft, remove from heat and allow to cool
step 9
Pour the cooled mixture into a liquidizer and liquidize until completely smooth
step 10
Pour the mixture into a clean saucepan, passing it through a sieve first. Use the back of a spoon to push the last of the mixture through. This will create an even smoother soup.
step 11
Serve with a sprinkling of croutons and/or fried lardons. You can also use chopped pieces of bacon.
