Preheat oven to 425°.
Place the potatoes in a large bowl. Sprinkle with the oil, salt, and pepper and toss to coat well. Spread out on baking sheets and bake for 30-45 minutes until browned on the edges. How long you need to cook them depends on large or small you cut your potatoes. Remove and let cool.
Meanwhile, cook the bacon. Drain. Let cool.
In a small bowl, combine the bacon, green onions, Creole seasoning, and dressing.
Serve potatoes topped with a large dollop of the dressing.
