Preheat oven to 400. Preheat a small nonstick pan over medium high heat. Rub potatoes with a drizzle of oil. Place potatoes on a baking sheet and bake for 1 hour. While potatoes cook, add chopped bacon to hot skillet and brown until bits are crisp. Add scallions and cook scallions together with bacon 1 minute more. Transfer bacon bits and green onions to a paper towel lined plate to drain. Allow potatoes to cool enough to be handled, 5 minutes. Preheat broiler to high. Cut potatoes in half and scoop out the flesh into a small bowl. Smash potato flesh together with sour cream until combined using a potato masher. Stir in cheddar cheese, bacon and scallions and season with salt and pepper, to your taste. Scoop filling back into potato skins and place on a cookie sheet. Top each potato with extra cheese if desired. Place potatoes in oven and brown under broiler, 6 inches from heat 5 minutes.
