A Nesco roaster oven is a slow-cooker and a direct competitor to the Crock-Pot brand. It is used to make a variety of foods from roasts to soup to cookies and more. Nesco sells its roaster ovens in sizes of five, six, 12 or 18 quarts.
The 18-quart option is Nesco's most popular roaster oven and comes with a number of different material and design options. These ovens range in price from $79.99 for an ivory and porcelain unit to $149.99 for the stainless steel variety. All of the 18-quart units come with Nesco's patented "Circle of Heat" core, providing insulation and auto-temperature control for ideal roasting and baking.
