Lightly grease the outside of potatoes, cut small slit in the top and bake at 425 degrees for 45 minute or until soft.
Let stand until cool enough to handle (about 15 minutes). Cut the potatoes in half lengthwise and scoop out the cooked potato, leaving a very thin layer of potato (save the cooked potato for mashed potatoes or hash browns).
Brush the outside and inside of skins with melted butter. Sprinkle the inside with seasoned salt and Parmesan cheese. Place on a lightly greased baking sheet. Bake for 8 minutes or until crisp and bubbly.
Fill each with Cheddar cheese and bacon. Bake 3 minutes or until the cheese is melted.
Top with a dollop of sour cream and sprinkle of chives. Serve immediately.
