To boil potatoes for mashed potatoes, the typical recommended time is about 15 to 20 minutes when the potatoes are peeled and cut into quarters or chunks. This timing allows the potatoes to become tender enough to mash easily

. Here are some key details:

• Start by placing peeled and quartered potatoes in cold salted water, then bring to a boil

• Once boiling, reduce the heat to maintain a simmer and cook covered for 15 to 20 minutes, or until a fork easily pierces the potatoes

• If boiling whole potatoes with skin on, it can take longer-about 30 to 40 minutes-because of the larger size and extra thermal mass

• To check doneness, poke with a fork; potatoes should be tender and nearly falling apart

Boiling potatoes cut into chunks is preferred for even cooking and faster boiling, resulting in smooth mashed potatoes. Whole potatoes take longer and may yield a different texture or flavor if skins are boiled on

. In summary, for mashed potatoes:

• Peel and cut potatoes into quarters.
• Boil in salted water starting from cold water.
• Cook for about 15 to 20 minutes until fork-tender.
• Drain and mash with butter, milk, and seasoning as desired

This method ensures fluffy, creamy mashed potatoes in a reasonable time.
