The Breville Smart Oven led the pack in virtually every one of our testing metrics, leaving all of its competitors in the dust. During our testing it made the best toast, most delectable cookies, and some of the tastiest bagels we've ever had the privilege of eating. We found it to have astounding temperature accuracy, making a great choice for discerning bakers, and its controls made it far and away our favorite model to use. It is a bit on the expensive side, but if you don't mind paying for quality, the Smart Oven certainly will not disappoint.
For an extra $20 the Breville Smart Oven Pro is essentially the same machine as the Smart Oven, but adds a slow cooking feature that allows you to cook at a low temperature for an extended period of time.
