A toaster oven is a small kitchen appliance that combines the functions of a toaster and an oven. It can toast bread, bake, broil, and reheat food, making it versatile for various cooking tasks. Toaster ovens typically have adjustable temperature settings and timers, allowing users to cook food to their desired level. These appliances are energy-efficient and take up less space than traditional ovens, making them ideal for small kitchens or for those who want to save on electricity. Many models come with features like convection cooking, which circulates hot air for even cooking, and removable trays for easy cleaning.
