  1. Use the right kind of potato. Russets or Yukon Gold work well for mashed potatoes.
  2. Cook the potatoes in cold water.
  3. Once the potatoes are cooked drain the water. Leaving the potatoes in the water will cause the potatoes to take on water.
  4. You can peel the potatoes 24 hours before you cook them but keep them in cold unsalted water.
