Scrub and clean the outside of regular baking potatoes. Being careful to not cut all the way through, slice each potato into 6-8" sections down the length of the potato. Insert a wedge of onion and a pad of butter into each slit. Sprinkle salt, pepper and dried parsley to taste over the butter and onion areas. Wrap each potato in aluminum foil, place on a baking sheet and bake them in the oven as you would regular baked potatoes for an hour or longer, depending up the size of your potatoes. Serve piping hot. Enjoy!
