Rolled oats, also known as old-fashioned oats, are whole oat groats that have been steamed and then flattened with large rollers to create flattened flakes. This process makes them easier and quicker to cook than whole oats. Rolled oats retain most of their natural nutritional value and are a popular choice for making porridge, granola, and baked goods. They can be used in a variety of dishes and provide a hearty, nutritious base for breakfast cereals and recipes.
