Roaster ovens are tabletop appliances that roast food by distributing heat throughout the roasting chamber rather than heating with the use of gas or exposed coils similar to a conventional oven. Most roaster ovens consist of an electric heating element, a knob with adjustable temperature control and a large, removable pan covered by a lid. The food is often placed on a rack that fits inside the pan, similar to roasting food in a conventional oven and a traditional roasting pan. More exotic convection roaster ovens feature an oven fan that circulates hot air for moist, delicious results and faster cooking times. Some roaster ovens will even convert into a food warming buffet server that have separated food chambers, also called serving dishes. A common size roaster oven is 18 quart, but other size roaster ovens are also available.

Roaster ovens can be used to bake, cook, roast, steam, or slow cook a variety of foods such as turkey, meats, roasts, vegetables, soups, and stews. Roaster ovens have become very popular among large inside and outside gatherings for their portability, quality cooking and food warming properties.
