I had parsnips before in the States and didn't like them! I don't remember how I fixed them that time.
Over here, they're so commonly done with the 'Sunday roast' (which could be beef, lamb, chicken, etc) -- like many have said, roasted in the pan along with other veg such as carrots, potatoes, onions, & so forth. They're really delish roasted like that. When I first had them (again) at the in-laws - I wondered what they were & was surprised to find out they were parsnips, which I thought I didn't like!
