Every oven heats differently
Do not leave the food in the oven unattended,
especially dishes that cook without a lid. Before the surface becomes too dark, it is best to cover it with parchment paper. If you do not know exactly how much heat your oven heats up, it is worth buying an oven thermometer (specialized trade)
