The AEG CCB6440BBM can handle oblong roasting pans and Dutch ovens with ease. The upper-right cooking zone can be expanded so you can use it as an extra long cooking zone. The oven features telescopic rails. Thanks to these rails, you can easily slide your baking sheets and grills in and out, similar to a drawer. This telescopic sliding system has 2 levels, so you can easily prepare 2 dishes at the same time.
