Preheat the oven to 425°F.
If necessary, prep the potatoes by cutting them into equal-sized pieces and then coat them with oil. Most recipes say to do this right in the roasting pan.
I prefer to transfer them to a bowl, add the oil, season with salt, and stir them. This way, I know I will get all of them coated.
I always feel I'm not getting them coated completely when I coat them in the pan.
Spray the bottom of your roasting pan with spray olive oil. You may think this is necessary, but we've found it prevents the potatoes from sticking even though they are coated with oil.
Place the roasting pan into the oven and roast for 20 to 30 minutes until the potatoes are done. Halfway through the cooking process, flip the potatoes using a sizeable heatproof spatula.
