Ok so I found this on pinterest one day and made some adjustments to how to do this an easier way. A great way to make a potato look fancy and wow your guests.
Pre heat oven to 450
Scrub potato clean
With a sharp knife (which ever size you like hehe) make slices almost through the whole potato going width NOT length.
I found it easier to leave some of the sides on and go along the inside to make a pocket.
baste whole potato in Olive Oil then sprinkle Salt and pepper.
Place in oven on a cookie sheet.
Bake for 40-60 minutes.
when finished baking let cool and then slide butter into slices and whatever other toppings you like.
