Chicken roasted with vegetables—nothing is more delicious, or easier, but pulling off this classic as a slow roast is bit more complicated. It is literally impossible to overcook the bird, which is exactly the way most roast chickens go astray. The wrinkle lies with the vegetables: root vegetables (carrots, parsnips, potatoes - the vegs that taste especially yummy roasted around a chicken) will never get done at the low temperature that’s ideal for roasting chicken. So when slow roasting a chicken with potatoes, or onions, or parsnips, or carrots it is common to blanch them or fry them briefly to soften their tough fibers before throwing them in the roasting pan. But not if you think young.
