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
