Expert Tips

  • This recipe is made with red-skinned potatoes which are low in starch, or "waxy." For fluffier mashed potatoes, use russets or baking potatoes, which are high in starch, or use a medium starch potato such as Yukon gold or long whites.


  • Replace the butter with ghee, olive oil, or coconut oil.
  • Replace the cream or milk with coconut milk or broth.
  • Replace half of the potatoes with cauliflower for a lighter mash.
  • Add some chopped cabbage or kale to the pot for an Irish-style mash.
  • Replace one-third to half of the potatoes with peeled and cubed rutabagas.
