A convection oven is a type of oven that uses a fan to circulate hot air around the food. This helps to cook food more evenly and quickly compared to traditional ovens, which rely on radiant heat. The even heat distribution can result in better browning and crisping, making it ideal for baking and roasting. Convection ovens can be used for a variety of cooking tasks, including baking cookies, roasting vegetables, and reheating leftovers. Many modern convection ovens also come with additional features, such as multiple cooking modes and temperature controls, enhancing their versatility in the kitchen.
