Add the potatoes (skin on) to a large pot of boiling water. Boil for 25 to 28 minutes depending on the size of your potatoes or until barely fork tender. You want them cooked through, but don't overcook or the skins will start to come off.
Meanwhile, preheat the oven to 450 degrees F and line a baking sheet with foil.
Carefully remove the potatoes from the pot and pat dry. Cut the potatoes in half and set on the prepared baking sheet. Brush all skin sides of each potato with olive oil, and then slightly smash each potato.
Top each half potato with ⅓ tablespoon butter (more or less if desired) then sprinkle each potato with 1 tablespoon brown sugar and salt to taste.
Bake for 20 to 25 minutes or until golden and skins are slightly crispy.
Notes
Butter and brown sugar measurements are a guideline. Use more or less as desired. This recipe is a guideline for any variations you can dream up!
