Raw oatmeal is a kind of food with low sugar and high nutrition, which is relatively hard without processing. Usually you can cook slowly when you cook, and you need to keep stirring in the middle. It is better to control the cooking time to 20-30 minutes, and you can cook it longer if you like soft food. Cooking for too long is not recommended. The longer the raw oatmeal is cooked, the more likely it is to destroy its nutritional value.
