It is easier to pull food out of side-opening ovens, especially for people that may find it difficult to reach up and over conventional ovens. With the Fagor Side-Opening Convection Oven, the door can be set to open left or right to work best for the chef, according to Epicurious.
Because of the way the door opens in a side-opening oven, steam escapes differently and makes it less likely for a cook to get a face-full of heat. It also makes basting and seasoning roasts more simple, as the need to reach up and over an open door is no longer an issue. This makes baking more simple and comfortable for most people than with the traditional oven door.
