Different Types of Oatmeals- Groats, Rolled and Steel-cut

Different Types of Oatmeals- Groats, Rolled and Steel-cut

Now that you know how to cook oat groats in a rice cooker, let us look at the different forms of oats and how they are different from each other.

1. Oat Groats

Oat groats are whole oats simply without the husk. Then they are further polished to bring out the nutty flavor before being packaged for sale in grocery stores.

Oat groats are not rolled flat like regular flaked oats or grounded into a powder. And they still have their edges intact. That is why oat groats take longer to cook than rolled or steel-cut oats.

Oat groats can be consumed raw, cooked, steamed, or sprouted (like other seeds or grains).

2. Rolled Oats

Rolled oats are also known as oat flakes. They are made from steaming oat groats and rolling them into small flakes.

These flakes are pre-steamed during processing to soften them, making them cook faster once the liquid is added. The pre-steaming step also helps to stabilize their volume so that they don’t break down quickly once cooked.

In other words, they are instant oats. Rolled oats are most commonly found in any grocery store. 

3. Steel-cut Oats

Steel-cut oats are groats that have been chopped up into two or three pieces with steel blades. To make them even easier to digest, they are frequently mixed with even a softer variety of oats, such as rolled oats. Steel-cut oats are most commonly found in granola bars.

Steel-cut oats are not considered whole grains because of their chopped states. However, they contain significantly more fiber than rolled oats. In fact, one cup of steel-cut oats contains five grams of fiber- almost one-third of your daily recommended intake.

In addition to being high in fiber, they also boast a whopping 6-gram of protein per serving.
