Cook Time: Depending on the size of the potato the cook time will vary.
To bake in the oven do 425 degrees for 30 minutes, re-coat in oil, and cook another 30-40 minutes.
Feel free to season your potatoes with spices or herbs if you want.
You do not need the cutting tool to slice potatoes, but it does speed things up quite a bit.
