A convection oven is a type of oven that uses a fan to circulate hot air around the food. This helps to cook the food more evenly and often more quickly than a traditional oven. The even heat distribution can result in better browning and crisping, making it a popular choice for baking and roasting. Many convection ovens also have the option to use conventional heating methods, allowing for versatility in cooking. They can be used for a variety of dishes, from cookies to roasted vegetables, making them a valuable tool in many kitchens.
