Put your potato in a preheated hot oven, 200 degrees C, 400 degrees F or Gas Mark 6, for one to one and a half hours depending on the size, until they are squeezable. You can put them straight onto the oven shelf or on a metal tray.
You might like to rub the skins with oil and then sprinkle them with salt before baking to give lovely crispy skins. In my opinion, this results in the perfect oven baked potato!
A quicker way to bake a potato
By putting it in a saucepan of water and bringing the pan to the boil before cooking for 5-10 minutes, you can get away with less cooking time in the oven.
In fact you can reduce the baking time to around 30-60 minutes depending on the size.
Handy if you are hungry and don't want to wait quite so long for your meal. The skins will not turn out as crispy using this method, however.
