Conventional ovens allow you to cook more food inside the appliance. Convection ovens rely on the air to circulate. Crowding the oven with too much food may prevent everything from cooking properly. Conventional ovens generally have more racks and room inside the appliance than counter top convection ovens, which means you may prepare a large meal without worrying about keeping foods warm.
Since convection ovens cook food quickly, you have to adjust the cooking time and temperature of most recipes. Adjusting the oven can become frustrating, especially for a new cook. It can take a lot of time to get use to a convection oven, and you may spend many hours in the kitchen watching the food cook. Conventional ovens do not require any adjustments to recipes so you do not have to worry about food burning.
Convection ovens cook foods best in shallow and low pans because deep cookware can prevent the oven air from circulating. When you cook in a conventional oven, you do not have to worry about the pan size. Conventional ovens cook foods in casseroles, covered dishes and deep roasting pans because the appliance relies solely on heat instead of air circulation. When you cook with a conventional oven, you can use virtually any type of oven-safe cookware.
Convection ovens generally take up more space than conventional ovens. Most convection ovens sit on counter tops or reside in the kitchen wall. The multiple doors, large fans and compartments make the convection oven more bulky, which requires it to take up more space in the kitchen. Conventional ovens are usually all the same size. While they can take up more square footage in a kitchen, they fulfill most cooking needs without taking up much needed storage space.
Convection ovens are more expensive than conventional ovens. The high-end appeal, fan and convenience make the oven more desirable. The more common conventional ovens are offered in many styles, which allow the price to remain low on many models. Thus, a conventional oven may cost less than a convection oven.
