Other forms: roasted, roasting, roasts
To roast is to cook meat or vegetables in the dry heat of an oven until brown. Roast a chicken, roast potatoes, roasted vegetables.
The browning is the point, and it needs dry heat and room: vegetables piled on top of each other steam instead. Meat can also be roasted on a turning spit over a fire, and coffee beans and nuts are roasted too. A roast is also the piece of meat itself, and a Sunday roast is the big British meal built around one. To roast somebody is to make jokes about them at length, usually friendly ones, and a roast is now a whole comic show.
