As you cut your potatoes place in a pot of water to avoid discoloring. Cook small 1/2 inch pieces 2 minutes in boiling water and drain. If you have larger pieces or whole potatoes, boil up to 10 minutes and drain. You want the potatoes to be hot through, but not over cooked. Remember no larger than 2 inches.
Bring the stew to a boil and then allow it to simmer. It generally takes about 10 to 20 minutes to cook the potatoes to fork tender, depending on the size of your cubes and the reheating method. Another option is to boil the potatoes in a cooking pot filled with water.
