Large Flaked Oats are simply oat groats that have been toasted and rolled into flakes so they cook quicker. Large flake rolled oats are one of the most common types of breakfast oatmeal, and are the oats most often used in baking applications. Our Gluten Free Large Flake Oats take 5 – 10 minutes to cook, and if that isn’t fast enough for you then check out our Gluten Free Quick Oats.
