Boiling potatoes correctly gives you tender pieces ready for mashing, salads, or serving as a side. The timing depends mostly on whether you leave them whole or cut them into chunks.
What you'll need
- Large pot
- Potatoes
- Water
- Salt
- Fork or knife for testing
Step by step
- Prep the potatoesScrub the potatoes clean and peel them if you prefer. Cut them into even chunks for faster, more uniform cooking, or leave small ones whole.
- Start in cold waterPlace the potatoes in a pot and cover with cold water by about an inch. Starting cold helps them cook evenly from the outside in.
- Salt the waterAdd a generous pinch of salt to the water. This seasons the potatoes as they cook rather than just the surface.
- Bring to a boilHeat until the water reaches a rolling boil, then lower to a steady simmer so the potatoes do not knock apart.
- Time by sizeCut chunks usually take about 10 to 15 minutes, while whole medium potatoes take about 20 to 25 minutes. Larger whole potatoes take longer.
- Test with a forkPierce a piece with a fork or knife; it should slide in easily with no resistance. Drain right away once tender.
Handy tips
- Cut potatoes into similar sizes so they all finish at the same time.
- Drain promptly and let them steam-dry a minute for fluffier mash.
- Save a little cooking water to loosen mashed potatoes if they get too thick.
Heads up
- Draining a heavy pot of boiling water is a burn risk, so pour it away from you and keep children clear of the sink.
FAQ
How long do I boil potatoes for mashing?
Cut them into chunks and boil for about 10 to 15 minutes, until a fork slides in with no resistance. Cutting them speeds up the cooking and helps them mash smoothly.
Should I start potatoes in cold or hot water?
Cold water is best because it lets the potatoes heat gradually and cook evenly. Dropping them into boiling water can leave the centers undercooked while the outsides fall apart.
Do I peel potatoes before or after boiling?
Either works. Peeling after boiling keeps more nutrients and can be easier for some potatoes, but peeling before is simpler if you are cutting them into chunks.
