This will depend on the size of the potatoes and the heat of the oven.
If you want to bake potatoes in their jackets a useful technique is to push a metal knife (It must be completely metal like a stainless steel dining knife with no bone or plastic handles) or metal skewer right through or at least into the middle of each potato - the metal will conduct the heat into the centre of the potato and this will reduce the cooking time.
If the potatoes are large you may want to halve or quarter them and place them on a baking tray. Peeling the potatoes and cutting them into smaller portions will also reduce baking time. If you pack them close together they will take longer to cook, so space them out.
Generally about 30 - 40 minutes in a moderate oven should be enough to bake a medium sized potato. Unless you have a small oven, or are baking something else in the oven at the same time, it is not a cost effective way of cooking potatoes.
yes
the same time as baking 1 potato if your oven is large enough
No matter how many potatoes you bake - set the oven at 350 degrees and bake them for one hour. Larger potatoes may take longer. Always prick, pierce or cut a potato before baking as they can explode and make a mess of the oven, if the skin is unbroken and the steam cannot escape.
depends on what you are trying to bake and what temperature the oven is set to
If you bake them in an oven at 400 degrees, it takes 45 minutes to one hour. In a microwave, it takes about 7 minutes. In a toaster oven, it would take 20 minutes.
About twenty minutes in the oven.
depends on the size - about an hour at 350 - bake it on foil because sugars will ooze out and are very hard to clean up
You can bake one potato in a microwave in about 3 minutes. Test it with a fork to see if it is cooked right through. In a traditional oven it is wasteful to bake one potato. You can fill your oven with potatoes and bake them all in about ten minutes. Make sure the oven is hot enough to start with.
one hour
It will take about 2 to 2.5 hours. For a large potato at 350 it takes an hour so at 250 it will take longer. I bake mine at 450 for an hour and it comes out with a crispy skin and fluffy inside. I butter the outside of the potato before I bake it to get a crispy skin on it.
Around 1 hour or 45 minutes for a cake to bake
When using a conventional oven, the baking times do not change whether you are baking one sweet potato or a dozen sweet potatoes. The baking times only change when you put additional items into a microwave oven.
