  • 8-10 Idaho Russet or Yukon Gold potatoes
  • 3/4 cup whole milk or heavy cream
  • 1/2 cup melted butter


  • Peel, rinse and chop the potatoes into small chunks. Fill a large sauce pan with cold water and season generously with kosher salt.
  • Place the potatoes in the pot and bring to a boil. Reduce heat and simmer until tender when pierced with a fork, about 20 minutes.
  • Drain the potatoes in a colander then return to the pot. Add the milk before mashing the potatoes with a masher.
  • Transfer the potatoes to an airtight container and refrigerate for up to 2 days.
  • Before serving, return the potatoes to a pot over medium heat or crockpot on low and add the melted butter.
  • Stir the potatoes occasionally to fluff and incorporate the butter. Keep warm until serving time


  • Do not overcook the potatoes.
  • Leaving the boiled potatoes in the water will result in gummy potatoes.
  • Allow the potatoes to drain for a few minutes before returning to the pot.
  • Do not overmash the potatoes.
  • Using a mixer results in gooey potatoes.
  • Stick to a potato masher or ricer to create the creamiest potatoes.
