The smallest oven you can buy typically depends on the specific type of oven you are looking for. Here are a few options:
Countertop Toaster Oven: These compact ovens are designed to sit on your kitchen countertop. They are generally smaller than conventional ovens and can be used for toasting, baking, and broiling. Countertop toaster ovens usually range in size from about 0.2 to 0.8 cubic feet.
Mini Convection Oven: Mini convection ovens are small versions of traditional convection ovens. They use a fan to circulate hot air, resulting in faster and more even cooking. These ovens are slightly larger than countertop toaster ovens and typically have a capacity ranging from 0.5 to 1 cubic foot.
Compact Microwave Oven: While not a traditional oven, compact microwave ovens can also be used for cooking and baking certain types of food. These ovens often have a combination of microwave and convection cooking features. Compact microwave ovens typically have a capacity ranging from 0.5 to 1 cubic foot.
It's worth noting that the sizes mentioned above are approximate and can vary between different brands and models. If you have specific requirements or space limitations, it's best to check the specifications provided by the manufacturer or consult with a retailer to find the smallest oven that suits your needs.
