Not all toaster ovens use convection, but many modern models do. A toaster oven that uses convection is often referred to as a "convection toaster oven." Traditional toaster ovens work by heating the air inside the oven with electric heating elements, similar to a regular toaster. On the other hand, convection toaster ovens have an additional feature that circulates the heated air using a fan.
The convection feature in a toaster oven allows for more even cooking and faster cooking times, as the moving air helps distribute the heat evenly around the food. It can be particularly beneficial when baking, roasting, or cooking items that need to be crispy, as convection helps achieve better browning and texture.
If you're interested in purchasing a toaster oven with a convection feature, make sure to check the product specifications or look for models specifically labeled as "convection toaster ovens."
