The Breville Smart Oven lets you control the power with its innovative Elements IQ technology. Turn it up or down with the ease of a dimmer switch to distribute heat evenly and cook to perfection. Simply adjust to taste and this brilliant appliance delivers the right power at the right time. Broil function activates top three heating elements to the top only to melt and brown. Toast function activates top two and bottom two heating elements to seal and crisp. Bake function uses top two and bottom two heating elements with the convection fan turned on to ensure the item is cooked right through.
