Rolled Oats

Rolled oats, or old-fashioned oats, are oat groats that have gone through a steaming and flattening process.

They have a milder flavor and softer texture and take much less time to make than steel-cut oats, as they have been partially cooked.

A bowl of rolled oats takes 2–5 minutes to prepare.

Rolled oats can also be added to goods like cookies, cakes, muffins and bread.

Quick Oats

Quick oats or quick-cooking oats are rolled oats that go through further processing to decrease cooking time.

They’re partially cooked by steaming and then rolled even thinner than old-fashioned oats.

They cook within a few minutes, have a mild flavor and soft, mushy texture.
