how long to boil potatoes for mashed

To boil potatoes for mashed potatoes, it typically takes between 10 to 30 minutes depending on the size and cut of the potatoes. Whole russet potatoes take about 30 minutes, quartered potatoes take about 15-20 minutes, and cubed potatoes take about 10-12 minutes to boil until fork-tender. It's best to start the potatoes in cold water with added salt and then bring to a boil. The potatoes are done when a fork easily slides into them without breaking them apart. This ensures even cooking and a creamy texture for mashing.
