Good to know

  • USDA describes the medium portion by the potato’s size before baking; the 114 g weight is the baked flesh this entry covers.
  • A cup of baked sweet potato (200 g) has about 180 calories.
  • The skin isn’t included. Butter, brown sugar and marshmallow toppings are separate entries.
