The great thing about pre-cooked udon noodles is that they are very easy to prepare! When you stir fry them, you can just let them sit in boiling water until they detangle and then finish them in the pan. If you want to use them for soups, you can place them in the soup pot and let them cook for about 3 minutes. That way, you always have perfectly cooked udon noodles that are thick, chewy, and delicious!
