A good baked potato is a crucial part to a good dinner at my house. You can enjoy them plain, cut them and fry them up, or load them up with all sorts of fillings
Wash your potatoes so they are clean and before you add the olive oil to the skin.
Make sure to use a fork or knife to pierce the skin 4-6x on each side. Then rub them in olive oil and sprinkle with salt.
Let the potatoes bake in the oven one hour at 400F. You'll know if they need more cooking time by putting your fork into the skin and if it sticks in smooth and easily, they are done.
