Preheat oven to 400°F (200°C).
Slice each baked potato in half lengthwise and scoop out the flesh, leaving about 1/4 inch of potato on the skins.
In a small bowl, mix vegetable oil, Parmesan cheese, salt, garlic powder, paprika, and black pepper.
Brush the potato skins with the oil mixture on both sides.
Place the potato skins on a baking sheet, skin side down, and bake for 10 minutes until crisp.
Flip the skins over and evenly distribute the shredded Cheddar cheese and crumbled bacon inside each skin.
Return to the oven and bake for another 8–10 minutes, or until the cheese is melted and bubbly.
Remove from oven and top each potato skin with a dollop of sour cream and a sprinkle of sliced green onions.
Serve warm and enjoy your loaded baked potato skins!
