Tips and Tricks
  • Make-ahead: If making these potatoes several days before and refrigerating them, allow them to come to room temperature before baking.
  • Heating: Check the center of the potatoes starting around the 35-minute mark to see if heated through.
  • Leftovers: Store any leftovers in the fridge and reheat in the microwave or the oven.
