The benefits of using a double oven include being able to cook more food in less time, having more oven space, using less electricity on smaller meals and easier preparation of multicourse dinners. A double oven also allows a cook to simultaneously prepare foods at different temperatures.
Problems such as overly dry meats or chewy vegetables that result from reheating foods can be avoided by setting one oven to keep things warm while the other cooks. Double ovens can be set to cook with different styles and temperatures, allowing the user to roast a turkey in one oven and bake a cake in the other. A cook can prepare twice as much food with a double oven, which is beneficial when cooking for family and friends during holidays and special occasions. Multicourse meals take less time to make when pies and potatoes can cook at the same time as the meatloaf.
Some double oven models have a smaller top oven that cooks food using less electricity than a full-sized oven, which improves the energy efficiency of preparing everyday meals. Many models also include deluxe features, such as easy-to-clean porcelain racks, automatic turn-offs and clear digital displays. Double ovens also make it easier to ensure everything finishes cooking at the same time.
