Place oil, dry dressing, and potatoes in container (I use Ziploc bag) and shake. Place on pan and bake in oven at 425 degrees F. The time depends on thickness of potatoes. For wedges I usually cook them about 35 minutes. I also wrap them in Reynold's Wrap aluminum foil.
I have also prepared these with squash, onions, peppers, etc., and have added cheese.

Good for leftover potatoes. Cook bacon, drain on paper towel, and crumble. Pour off all but 1/8 cup bacon fat. Saute onion until tender. Add sliced potatoes and heat through.
