Preheat oven to 400 degrees F. Poke potatoes with a fork, place on a baking sheet and cook for 1 hour.
Remove from the baking sheet, and allow to cool for about 15 minutes.
Once your potatoes are cooled cut each lengthwise into three sections, creating three long slices. (So each potato should yield two skins, plus a middle section that you can either discard, use to make something else, or keep to make some extra potato skins without the "skin").
Once you've cut all the potatoes, use a small spoon to scoop out about 70 percent of the potato to make a little boat. You still want to have a thick layer of potato near the skin, but you want it to be slightly hollowed-out in the middle to create a "boat".
Turn your oven on to a high broil. Brush the potatoes with butter on the inside and outside and place them back onto the baking sheet. Season with salt and pepper.
Broil for 7-8 minutes until the insides get a bit crispy from the melted butter.
Remove from the oven and add a generous amount of shredded cheese into each skin, topping with bacon pieces.
Place back under the broiler for about 3-4 minutes until the cheese is nice and bubbly.
Remove from oven and top with sour cream and chives or green onion. Serve warm.
Store leftover potato skins in the refrigerator. Rewarm them in the oven or microwave.
Scoop the filling from the baked potato and allow the skins to cool. Store them in a freezer safe container for 2-3 months. Thaw them in the refrigerator overnight and then continue with broiling and filling the shells (step 5 of the recipe).
