The idea for cooking oatmeal played in my mind as it is less time consuming and my mom once told me the way to cook this.

Types of Oatmeal

Before cooking the item, you need to know which one to choose and also know what the differences between them are. Several different oatmeals are there in the market. No matter which one you choose, all the oats are healthy and has similar nutrition values.

When I went to cook the oatmeal, I came with four different types in my cabinet. They all have a different use indeed.

  • Steel-Cut Oats

The whole oat grain is cut into smaller pieces to make steel-cut oats. The oatmeal which will be made with steel-cut oats will have a sweet, chewy and nutty flavor than the old-fashioned and quick-cooking oatmeal. This type of oatmeal is ideal for slow cooking.

Steel-Cut Oats
  • Old-Fashioned Oats

This one is also known as rolled oats, which is made by steaming the whole oat grain and then rolled up with a roller. They are cooked faster than the steel-cut oats, because of their surface area to absorb water. They are not ideal for slow cook.

Old-Fashioned Oats
  • Quick Cooking Oats

They are almost like the old-fashioned one. Cut into smaller pieces after steaming and rolled flat. The planeness and the little size make them absorb water and cook quicker than the rolled type. They have a creamy and a very smooth texture.

Cooking Oats
  • Instant Oats

The instant oats are made by steaming the whole oat grain, flattened with a roller, cut into smaller pieces and then steamed again. The oat is pre-cooked and then dried. Instant oats are made like BOOM!!!! Add hot water, stir, and its ready.

How To Start The Cooking?

Cooking oatmeal in a rice cooker is easy. First, take 1 cup of steel-cut oats or 1 cup of rolled oats. 1¾ cups of water/milk for the old-fashioned kind or 2½ cups of water/milk for the steel-cut one.

Cook Oatmeal

After that, add salt according to your taste. Close the lid of the rice cooker then. Keep that in mind steel-cut oats need 20-30 mins as this is ideal for slow cooking. Whereas, old-fashioned oats will get ready in 5-7 mins.

The machine will beep once the oatmeal is ready. Your meal is then ready to eat, stir and serve on the plates.

Cooking the steel-cut oats does not need monitoring. But keep an eye while cooking the rolled oats. The longer the rolled oats will be in the rice cooker, the less it will taste.
