Gather the ingredients.
Wash the potato and rub with olive oil, if desired. Prick the potato in a few places with a fork to allow steam to escape. Microwave the potato on 100% power for about 8 to 12 minutes, or until fork tender. Remove from oven after baking; wrap in foil and let stand for 5 to 10 minutes.
Unwrap potato and cut in half lengthwise. Let potato cool until it can be handled. Gently scrape the insides of the potato out, do not scrape all the way to the skin (leave a little potato around the edges and on the bottom). Reserve the scrapings and store in the refrigerator for another meal, if desired.
Heat the broiler and spray a small baking pan with cooking spray.
Season skins with seasoned salt and pepper. Sprinkle sliced scallions on each one. Place the potato skins in the prepared pan.
Lightly spray the potato skins with the butter flavored spray or drizzle with some melted butter. Place under broiler until golden brown.
Remove the potato skins from broiler and spread each with 1 tablespoon of sour cream. Serve warm.
