A toaster oven is a small kitchen appliance that combines the functions of a toaster and an oven. It is designed to toast bread, bake, broil, and reheat food. Toaster ovens are typically more energy-efficient than traditional ovens and can cook food faster due to their compact size. These appliances usually feature adjustable temperature settings and timers, allowing for precise cooking. Many toaster ovens come with additional accessories, such as baking trays and racks, making them versatile for various cooking tasks. They are popular for their convenience and ability to prepare meals without heating up a large oven.
