How Long to Boil Potatoes

Boiled potatoes are a basic side dish, but the result depends on the type of potato and how evenly it cooks. Boiling them too long makes them fall apart, while undercooking leaves the center hard. Knowing the correct boiling time helps achieve a tender, consistent texture.

If you are wondering how long to boil potatoes, whole medium potatoes usually take 15 to 20 minutes after the water starts boiling. Cut potatoes cook faster and are typically done in 10 to 15 minutes, depending on the size of the pieces.

Why potato size and type matter

Potatoes cook from the outside in. Larger potatoes take longer for heat to reach the center, while smaller or chopped potatoes cook more quickly. Waxy potatoes hold their shape better, while starchy potatoes soften faster and may break apart.

Starting potatoes in cold water allows them to heat gradually and cook more evenly, reducing the risk of an undercooked center.

Does boiling time change for different uses?

Yes, boiling time can vary depending on how the potatoes will be used. Potatoes for salads are usually boiled until just tender, while potatoes for mashing can be cooked slightly longer for a softer texture.

Testing with a fork is the most reliable way to check doneness. The fork should slide in easily without resistance.

Practical tips for perfectly boiled potatoes

Start potatoes in cold, salted water.
Cut potatoes into similar sizes for even cooking.
Bring water to a boil, then reduce to a gentle boil.
Check doneness near the minimum cooking time.
Drain immediately once potatoes are tender.

Common mistakes to avoid

Adding potatoes to already boiling water, which causes uneven cooking.
Overboiling until potatoes absorb too much water.
Cutting potatoes into uneven pieces.

Additional questions people often ask

Many people ask whether potatoes should be peeled before boiling. Both methods work, but boiling with the skin on helps retain flavor and nutrients.

Another common question is whether boiled potatoes can be reheated. Potatoes reheat well when steamed or warmed gently with a little moisture.

Final thoughts

Knowing how long to boil potatoes makes preparation simple and reliable. With a boiling time of 10 to 20 minutes depending on size and type, potatoes turn out tender, evenly cooked, and ready for any dish.
