What’s the Difference? Steel-Cut, Rolled and Quick Oats


Oatmeal is the breakfast of champions this time of year. We also love it in pancakes, muffins, cookies, scones, and bread. Anything that can be passed off as breakfast, really. But we’re always a little confused when a recipe calls for one particular kind of oats, be it quick-cooking or old-fashioned. And can we substitute one for another?

All oats great and small start off life as an oat groat. A groat is simply the whole unbroken grain of oat. Before being made into any other variety of oat, groats are usually roasted as a very low temperature. This not only gives the oats their nice toasty flavor, but the heat inactivates the enzyme that causes oats to go rancid. This makes oats more shelf-stable.

Whole groats are becoming much easier to find these days. They’re also processed into these common kinds of oats:

Steel-Cut Oats – We get steel-cut oats when the whole groat is split into several pieces. Simmered with water, steel-cut oats retain much of their shape and make a chewy, nutty-tasting porridge. Substitute: Whole Oat Groats

Rolled Oats – Whole grains of oats can also be steamed to make them soft and pliable, and then pressed between rollers and dried. The resulting “rolled oats” re-absorb water and cook much more quickly than whole groats or steel-cut oats. When a recipe calls for “rolled oats” or the packaging mentions it, they generally mean the thickest rolled oat, which retains its shape fairly well during cooking. Substitute: Quick oats can be substituted, but the texture will be lost

Old-Fashioned Oats – The source of much confusion, old-fashioned oats are actually the same as rolled oats. You’ll usually see them called “Old-Fashioned Rolled Oats” on packaging.

Quick or Quick-Cooking Oats – These are oats that have been pressed slightly thinner than rolled oats. They cook more quickly, but retain less of their texture. Substitute: Rolled Oats or Instant Oats

Instant Oats – Pressed even thinner than quick oats, instant oats often break into a coarse powder. They cook the quickest of all and make a very soft and uniform mush (erm…for lack of a better description). Substitute: Quick Oats

As a final note, Harold McGee in On Food and Cooking says that all processed oats have the same nutritional value. This was a surprise to us. We assumed that the more processed the oat, the less nutrition would remain. We’re happy to be proven wrong this time!
