A convection oven is a type of oven that uses a fan to circulate hot air around the food. This circulation helps to cook food more evenly and often more quickly than traditional ovens. The consistent airflow allows for better browning and crisping, making it ideal for baking and roasting. These ovens can be used for a variety of cooking tasks, including baking cookies, roasting vegetables, and reheating leftovers. Many convection ovens also come with multiple cooking settings, allowing users to adjust temperature and fan speed for different recipes.
