To bake a sweet potato in the oven, preheat the oven to 400F (200C) and bake the sweet potato for about 45-60 minutes, depending on its size. Check for doneness by piercing it with a fork - it should be tender all the way through.
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.
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.
The first thing you will want to do when cooking a sweet potato in a convectional oven is to preheat the oven to 375 and put the sweet potato in a baking pan. Cook the sweet potato for a half hour. Take the sweet potato out and stab it with a fork a couple of times. Cook the sweet potato for another half hour.
Depending on the size of the sweet potato, you would bake 35 to 45 minutes. Check for doneness and bake longer if needed. Larger potatoes require longer to get done.
That would probably work if you oven had a very low setting. (Some people might consider it not very eco-friendly though). And you would probably want to wrap the potato in foil to prevent it drying out - otherwise you'll end up with dried sweet potato in the morning. A quicker alternative would be to microwave the sweet potato first, then oven for crispness. Or, sticking a metal skewer through the sweet potato cuts down cooking time in the oven significantly, since heat is attracted to the middle of the potato as well as the outside.
If you cook a potato in the microwave for 10 minutes, it is done. Putting it in the oven would only crisp the outside. If you want to do that, 10 minutes should do.

To reheat a baked potato in the oven, preheat the oven to 350F, wrap the potato in foil, and place it on a baking sheet. Bake for about 15-20 minutes until heated through.
To quickly bake a potato, wash it, pierce it with a fork, rub it with oil and salt, then microwave it for 5-7 minutes or bake it in a 425F oven for 45-60 minutes.
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.
the same time as baking 1 potato if your oven is large enough
i just cooked some and it took me about an hour and 25 min.
