Great question! Are mashed and twice-baked potatoes identical? Not quite. The big differences between the two preparations is that mashed potatoes are boiled, and the twice baked are well, baked. Then re-baked after mixing the scooped-out baked potato with any mixture of seasonings, heavy cream and cheese, mixed thoroughly and returned to the potato skins (sometimes with an additional topping for texture. The mashed potato? Simply boiled in chunks (usually peeled but skin-on is an option) then mixed with added ingredients. In short, the two final preparation methods are close, but again – not quite.
