Cut potatoes in half lengthwise; scoop out pulp, leaving a 1/4-in. shell (save pulp for another use). Place potato skins on a greased baking sheet.
In a small bowl, combine the oil, Parmesan cheese, salt, garlic powder, paprika and pepper; brush over both sides of skins.
Bake at 475° for 7 minutes on each side or until crisp. Sprinkle bacon and cheddar cheese inside skins. Bake 2 minutes longer or until the cheese is melted. Top with sour cream and onions. Serve immediately.Yield: 8 servings.
