Thanks to 4D hot air the Bosch HBG675BS1 allows you to prepare 1 to 4 dishes at 4 different settings at the same time. Other food preparation settings such as slow cooking, the fan grill mode, and defrosting make preparing a multitude of meals a breeze. The 10 automatic programs have been pre-programmed. This way, all you have to do is select the right dish in the selection menu, and the oven determines the right temperature and preparation time. Cleaning the HBG675BS1 is also easy. The pyrolysis cleaning system burns all the grease and grime, so all you have to do is sweep up the ashes afterwards.
