Heat your oven to 425. Line a 15 1/2 x 10 1/2-inch rimmed baking sheet with foil and spray the foil with non-stick spray.
Combine all of the ingredients in a gallon size zip-top bag. Seal the bag with the air still in it, and shake and turn it until the potato pieces are evenly coated with the oil and seasoning. Pour the potatoes onto the prepared pan and spread them into an even layer. Throw the bag away (one of the best parts).
Roast the potatoes for 40-45 minutes or until they are very tender and nicely browned. Stir the potatoes several times during cooking, more frequently toward the end of cooking to prevent them from burning on the bottom.
