A conventional microwave oven emits microwaves that pass through glass and plastic containers to cook food. A convection microwave oven combines basic microwave technology with radiant heat to let you roast, brown, and grill foods.
Convection microwaves have a heating element as well as a fan to circulate the heated air. This results in a more thorough job of cooking. Also known as speed-cook models, these units promise juicier pot roasts and crustier pizzas. Some units come with a pan for cooking bacon and crisping bread.
Another alternative heating method combines microwaves with intense light from a quartz halogen bulb to grill and roast food. This technology adds color and taste to meats while speeding cooking times.
Since convection microwave ovens allow multiple cooking modes in a single oven, expect to pay a little more.
