You need 1.40 kg for your group.

  • You need about 1.40 kg of raw potatoes to make mashed potatoes for 8 adults.
  • That is roughly 7 medium-sized potatoes.
  • Raw weight accounts for peel and cooking loss, so buy a little extra if using thin potatoes.
  • For a buffet or if you want leftovers, switch the extra allowance to add 10-15%.

Next stepPeel and cook from cold salted water for boiled or mashed, or roast at 200 C / 400 F for 45 minutes for roasted.
