Generally, you boil potatoes when you plan to mash them or toss them into a salad, though boiled potatoes can also make a quick side dish. Boiling also cooks potatoes very evenly all the way through and usually only takes 10 to 20 minutes.
In a pot, heat water until it boils. Once it boils, add in your potatoes. After about 20 minutes, you can try forking in your potatoes to see how tender it is. Now, another factor on the length of cooking potatoes is how big your potatoes are. Of course, if you use really small potatoes, they will become tender easily.
