I love these.
Scrub and cut out any blemishes on about 8-10 large potatoes. Prick with a knife and bake in preheated 400° oven for one hour or until tender. Remove and scoop baked potato out (hold potatoes with a hot pad), leaving a bit of potato with the skin so it will hold together.
Mash the hot potato with one recipe reduced fat or regular sour cream--recipes on this site--with double the onion powder, garlic powder and salt. Add a bit of water if the potato mixture is too stiff. Taste and add seasonings or salt if needed.
Stuff potato skins, fluffing the mixture up in peaks if possible. Return potatoes to oven and bake about a half hour or so until they are hot and the peaks start to brown.
