Ingredients

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

Instructions

  • Peel, rinse and chop the potatoes into small 1-inch cubes or chunks. Fill a large saucepan with cold water and season with a pinch with kosher salt.
  • Place the potatoes in the pot and bring to a boil over medium-high heat. Reduce to medium-low heat and simmer for 20 minutes.
  • Stir potatoes occasionally and pierce with a fork to test they are done. Drain the potatoes in a colander then return to the pot.
  • Heat the milk in a small saucepan or in the microwave in a microwave-safe bowl. Next, add the hot milk before mashing the potatoes with a masher.
  • Transfer the potatoes to an airtight container or metal bowl covered with plastic wrap or aluminum foil and refrigerate for up to 2 days.
  • Before serving, return the cold mashed potatoes to a pot over medium heat or slow cooker on low and add the melted butter.
  • Stir the potatoes occasionally to fluff and incorporate the butter. Keep warm until serving time.
  • Transfer the warm potatoes to glass bowl or serving dish and serve. Season with salt and black pepper.

Notes

  • 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 over mash the potatoes.
  • Using a mixer results in gooey potatoes.
  • Stick to a potato masher or ricer to create the creamiest potatoes.
