1I used russet today. I just washed the skin and cut into pretty large cubes. I drizzle about 1 tbsp of olive oil in a non stick skillet (I've used cast iron skillet before as well). Place potatoes in, cover with lid and place burner on med. low setting. Stir about every 15-20 min. replacing lid each time. If potatoes are browning very fast, turn burner down a little. It took about 1 hr. for these to cook. I used pinto bean seasoning because I was going in a SW direction with supper.
