Poke holes in the baked potatoes with a fork and put them in the microwave for 15 minutes (turning once half way through).
Cut potatoes in half lengthwise; scoop out pulp and discard (or save for another use) leaving 1/4-inch shell.
Place on a greased baking sheet.
Combine oil, Parmesan/Romano cheese, salt, garlic powder, paprika and pepper and brush all over potato skins.
Bake at 475° for about 8 minutes skin side down and turn over.
Bake for another 8 minutes or so and then turn right side up.
Sprinkle bacon and cheddar evenly inside of skins.
Bake 2 minutes longer or until cheese is melted.
Top with sour cream and onions
