How To Cook Oatmeal in a Rice Cooker

When you are cooking oatmeal, it is important to know how long to cook it for. It can be time-consuming and annoying to watch a pot of good old-fashioned oats cooking, waiting for it to thicken up. This is where a rice cooker comes in handy! So, if you have ever asked yourself how to cook oatmeal in a rice cooker, the answer is actually very simple. Let’s find out more.

A rice cooker will automatically shut off once the water has evaporated and your oatmeal is cooked through. In this post, we will show you how easy cooking oatmeal in a rice cooker can be!

Before we dive in, though, let’s discover what steel-cut oats are.

What are Steel Cut Oats?

Oatmeal is usually made from steel-cut oats, which are simply oat groats that have been chopped into smaller pieces. The process of chopping the grains produces more surface area, making it easier for your body to digest and extract nutrients from them. Steel-cut oats take longer than regular rolled oats to cook because they need time in order to break down their thick layer of bran, so many cooks like to soak the oats before cooking them in order to cut down on the time needed.

The good news is, they can be cooked to perfection using a rice cooker. A rice cooker is an electric pot that can be used to cook grains, vegetables, and even some types of meat. Rice cookers are also known as fuzzy logic or induction heating cooking pots because they use a setting that heats the inner aluminum pot with microwaves or electromagnetic waves in order to create heat for cooking purposes.

When cooking steel-cut oats in a rice cooker, it’s important to be mindful of the liquid content. Steel-cut oats need more water than rolled or quick oats because they are thicker and denser, which means that there is less moisture inside them. It’s also very important not to cook your oatmeal too long when using rice otherwise the oatmeal can get overcooked and taste very dry.

What is the ratio of water to steel cut oats?

The ratio of water to steel-cut oats is about a half cup of liquid per one cup serving. This can be measured using any type of measuring tool, such as cups or spoons, which makes it easy for anyone, from novice cooks to expert chefs!

What are the benefits of cooking oatmeal in a rice cooker?

Cooking steel-cut oats in a rice cooker can be easier than boiling them on the stove. It takes less time to cook this way, and there’s less chance that you’ll over or undercook your delicious breakfast! Cooking oatmeal with water also has added health benefits such as the fact that it is lower in calories and fat than other breakfast options.

Are there any drawbacks to cooking oatmeal with a rice cooker?

There are no disadvantages that we could find! Cooked steel-cut oats taste amazing, and they’re good for you too 🙂

Can you substitute steel cut oats for rolled oats in a recipe?

Yes, you can. However, if cooking with a rice cooker it’s important to remember that the texture will be different and there may not be as much liquid inside because of the denser nature of steel-cut oats so make sure to adjust accordingly.

Which is healthier rice or oatmeal?

This is a question we often get asked. Steel-cut oats are whole grain and can be considered more healthy than white rice. This is because white rice is made from milled rice, which has the germ and bran removed during processing, whereas steel-cut oats are made with all of the parts intact, including, but not limited to:

The outer hull or husk (which provides dietary fiber), the inner kernel or endosperm that supplies B vitamins, minerals, protein, and carbohydrates, and the aleurone layer that is a source of additional protein, vitamins, and minerals.

So, steel-cut oats are healthier than white rice because they have more nutrients in their whole-grain form, whereas white rice has been milled to take out some parts, which would make it less nutritious. Granted, there are nutritional benefits associated with white rice, such as magnesium, but, generally, we reckon you’re better off with oats.

What is the difference between steel cut, rolled and instant oatmeal?

Steel-cut oats come from grinding up whole oatmeal grains into pieces which gives them a very dense texture so they take longer to cook. Rolled or flattened oats have been cut between two rollers to make them flatter and they are closer in texture to instant oatmeal.

Can you just add boiling water to oats?

It may come as a surprise but it is not a good idea to add boiling water or milk straight into your oats. The two liquids could cause the oatmeal to become too thin, giving it an unpleasant texture and taste.

What is the porridge setting on a rice cooker?

The porridge setting is a feature that you will find on most high-end rice cookers. It is designed to cook your oatmeal as slowly and gently at possible while making the oats soft so they can be easily eaten with a spoon or fork.

Can I substitute steel cut oats for quick oats in a recipe?

Steel-cut oats are whole grain, meaning they take longer to cook than the quick oats that have been pre-cut and rolled. If you use steel-cut oatmeal instead of quick oats in your recipe, it will need double the cooking time or more. Or if using steel-cut oats as opposed to quick ones for a certain dish, double the cook time, or better yet triple-check that they’re done before taking them out from under heat!

How Do I Cook Steel Cut Oats in a Rice Cooker?

Here is a healthy and easy oatmeal recipe for cooking in the rice cooker:

*Put your desired amount of steel-cut oats or other types of oats into the inner pot. Add liquid such as water, milk, or almond milk to cover them by about one inch. Because they expand in the water, you probably only want to use a cup of steel-cut oats per serving.

*Cook your steel-cut oats on the high-pressure setting with the quick release method or, if your cooker has one, the porridge setting. If you’re cooking rolled oats, use the porridge setting and cook them for about 30 minutes. The time will vary depending on your rice cooker so consult its user manual or follow the manufacturer’s directions.

*When you are ready to eat, stir in toppings of your choice such as fruit, maple syrup, brown sugar or coconut sugar before serving. You can also spice it up a little with some cinnamon or ginger.

*Steel-cut oats can be stored in the refrigerator for up to four days and they will last a week or more in your freezer if well wrapped. Mornings just got easier!
