You can cook udon noodles by boiling them, pan-frying them, or deep-frying them in some cases. No matter the cooking method, it's best to cook them until al dente as these chewy udon noodles will continue to cook when added to the frying pan. When using dried noodles, it’s best to first soak them in warm water for a minimum of 20 minutes before cooking them. For all other kinds (pre-cooked or frozen) make sure to follow the packing directions and shave off about 1 minute of cooking time so that you are left with slightly chewy noodles.
