Top and tail the parsnips, scrape roughly to remove any dirt, and cut lengthways into two or four if they are really big. Put three or four tablespoonfuls of olive oil into a pan and put int the oven at 425°F/210°C/Reg7 until hot.
Add the prepared parsnips to the cooking pan and cook for about 40 minutes or so until they are browned, turning a couple of times. When ready, take the parsnips out of the oven put on some kitchen paper to discard any excess fat and serve.
Serve with: Slow Roast Shoulder of Pork Recipe Notes: A lot of recipes say that you should blanch the parsnips first but in most cases I don't think you need to do this, and indeed it may result in the parsnips being over mushy.
