Potatoes typically take between 12 to 30 minutes to boil, depending on their size. Here is a general guideline for boiling potatoes once the water has started boiling:
- Baby potatoes (around 1 inch): 12 minutes
- Small potatoes (around 2 inches): 15 minutes
- Medium potatoes (around 3 inches): 20 minutes
- Large potatoes (around 4 inches): 25 minutes
- Extra-large potatoes (around 6 inches): 30 minutes
Smaller potatoes cook faster, while larger ones take longer. It is best to boil potatoes until they are fork-tender and easy to pierce. Cooling them for 5-10 minutes after boiling helps stop the cooking process. For cubed potatoes (about 1-inch pieces), boiling usually takes around 10-12 minutes. Boiling should start with the potatoes covered in cold water, then brought to a boil and cooked uncovered at medium-high to medium heat.
