First, make sure you scrub your potato thoroughly because you will be leaving the skin on. Preheat your oven to 400F

Once your potatoes have been washed and dried, start at one end and slice them almost all the way through and continue until you have reached the other side.

Place your sliced potatoes on a baking sheet and drizzle with olive oil and salt and pepper.

Bake for 40 minuets at 400, or until outsides are crispy

Top with a little melted butter and serve!
