Choose how you cook different meals at the same time. The Flex Duo™ design’s upper and lower zones work independently*. Cook a variety of food using different temperature and time settings or use the whole oven for large dishes. The Air Sous Vide* system continually senses the temperatures inside the oven and maintains an even temperature for a long period. Cook your food thoroughly, wherever it is in the oven, so it tastes deliciously tender and juicy.
