Extra Large Capacity

The large 1.4 cu. ft interior has sufficient space to cook for your whole family. Regardless of whether you are roasting an entire chicken or even a turkey, steaming veggies and fish simultaneously, or baking bread and cake, you will have more than enough space to do everything.

Easy Touch Display

Manage time, mode, temperature, or and kind of food preparation with a simple touch.

Dynamic Heating and Steaming

The convection system creates optimal circulation of heat within the oven. The internal fan distributes hot air and steam evenly to ensure food is perfectly cooked on all sides.
