Successfully mastering the kitchen starts with the basics, and one of the most frequent questions amateur and professional cooks ask is: how long to boil potatoes? It seems like a simple task, but the difference between a culinary masterpiece and a soggy disappointment lies in the precise minutes spent in the bubbling water.
When considering how long to boil potatoes, you must first assess your end goal. Are you looking for the creamy, velvet texture required for a classic Thanksgiving mash? Or perhaps the firm, tossable cubes needed for a German potato salad? Each recipe demands a different approach to timing. For instance, knowing how long to boil potatoes for mash means allowing them to reach a stage where they almost fall apart under their own weight.
Scientific factors such as altitude and the salinity of your water also play a role. However, the most dominant factor in how long to boil potatoes is the surface-to-volume ratio. A whole potato has a thick skin and a large core that heat must penetrate slowly. Conversely, a finely diced potato (small cubes) exposes more surface area to the boiling water, drastically reducing the time required.
| Potato Type | Whole (Medium) | Halved | Cubed (1") | Cubed (2") |
|---|---|---|---|---|
| Russet Potatoes | 20-25 min | 15-15 min | 10-12 min | 12-15 min |
| Red Potatoes | 15-20 min | 12-12 min | 8-10 min | 10-12 min |
| Yukon Gold | 18-22 min | 13-13 min | 10-12 min | 12-15 min |
| Sweet Potatoes | 20-30 min | 15-15 min | 12-15 min | 15-18 min |
| Baby Potatoes | 10-15 min | 8-8 min | 6-8 min | 8-10 min |
| Fingerling | 10-12 min | 7-9 min | 5-7 min | 6-8 min |
💡Pro Tip: Always start potatoes in cold water for even cooking. Test doneness with a fork - it should slide in easily with no resistance.

The Science Behind the Boil
Why does one potato take 10 minutes while another takes 30? It comes down to cellular structure. Calculating how long to boil potatoes isn't just about heat; it's about the breakdown of starch granules.
"As temperature rises, starch absorbs water and swells. If you stop early, the center is hard. If you go too long, pectin dissolves completely, resulting in mush."
To get the most accurate estimate for how long to boil potatoes, always use uniform sizes. If you have some small potatoes and giant ones in the pot, the small ones will be over-boiled by the time the big ones are ready.
- Baby Potatoes10-12 mins
- Cubed (1-inch)12-15 mins
- Halved Medium15-20 mins
- Whole Large25-30 mins
*Times vary by stove power. Always fork test!
