After hours of cooking your noodles, you have to decide what you want to do with them. In order to do that, you have to know how long they are good for. So, if you leave them at room temperature, they will be good for up to 2 hours. If you refrigerate them, they will last in the fridge for about 4-5 days. And, if you freeze them, they will remain good for up to 2 months.
