McCann’s Irish Oatmeal suggests measuring ¼ cup steel-cut oats and ¾ cup water into a deep microwave-safe bowl. Cook the oatmeal in the microwave on a high setting for five minutes; stir the oatmeal and then cook for an additional three minutes.
Steel cut oats take up to 30 minutes to cook on the stove top, however they can be prepared in the microwave in 10 minutes or less. However, the process for cooking steel cut oatmeal in the microwave depends on the specific brand of oatmeal used and the consistency desired. A softer consistency requires a longer cooking time than a firmer consistency. It is vital to use a deep microwave-safe bowl or dish to prevent the oatmeal from spilling over while cooking. The bowl can also be covered with microwave-safe plastic wrap to prevent overflowing.
Cook only one serving of oatmeal at a time, and do not fill the bowl more than half full. To prevent bubbling over and to achieve the desired consistency, oatmeal can be cooked for one minute at a time, followed by stirring. Check the oatmeal after each minute until the desired consistency is achieved. To prevent burns, allow the oatmeal to cool slightly before eating.
