For a vegetable gratin or pasta
minutes with a thermostat set at 200 °C (390 °F) (depending on the thickness of the gratin).
Naturally, it is necessary for the heat to penetrate from above and below. The lower level,
however, will work appropriately for potatoes, pastries and the medium level will work well

For the gratin,
position the grill tray at the highest level and insert the gratin dish.
Keep the door of the oven ajar and pull the drip tray out to protect the knobs from
heating. A notch on the drip tray indicates how far you need to pull out the drip tray. Position
the thermostat at 250 - 275 °C (480 - 530 °F) and keep a close eye on your dish.
