Some of the best electric roaster ovens, as of July 2015, are the Oster CKSTRS23, the Rival RO230-B, the Hamilton Beach 32229, the Nesco 4818-14 and the Oster CKSTRS71, according to Best Reviews Advisor. These roasters allow for variable cooking times for a number of different types of meats.
The Oster CKSTRS23 22-Quart Roaster Oven can roast a turkey of up to 22 pounds and features a removable rack, an enamel-on-steel roasting pan, a stainless steel body and a black lid. The Rival RO230-B 22-Quart Roaster Oven has many similar features, with an additional lid rest for convenient serving. The Hamilton Beach 32229 22-Quart Roaster oven features a sleek silver design and, like other ovens, offers portability for pot lucks and other group dinners.
The Nesco 4818-14 Classic Roaster Oven has a smaller capacity at 18 quarts, but it comes in red and ivory options and uses a unique "circle of heat" heating element. It also features a removable porcelain cookwell and an extra-high dome that helps dishes self-baste and maintain moisture. The Oster CKSTRS71 18-Quart Roaster Oven is another smaller option that includes a buffet server with three removable enamel-on-steel pans and lids, which allows for increased options for serving compared to the other top models.
