How Long Can You Leave Rice In A Rice Cooker(Fact Based)

Last Updated on August 29, 2021

Rice cooker is a kitchen appliance used to cook rice. It is a very useful kitchen tool that helps you save time and energy. This is because it cooks rice quickly and efficiently. A rice cooker is a great way to enjoy delicious rice every day.

However, there are some people who have been using their rice cooker for years without cleaning them properly. They just leave the rice in the pot until they use all of its contents. The problem with this method is that bacteria can grow on the surface of your rice cooker if left unattended. If not cleaned regularly, these bacteria will eventually make your food unsafe to eat.

Rice is one of the healthiest foods you can eat today since it is low in fat and high in carbs, both of which your bodies need to stay healthy and operate properly. Rice cookers were launched and well-received in the market since cooking rice in the conventional method with pots is a nuisance.

When you prepare too much rice, rather than wasting it by throwing it away, you can just reheat it and eat it. However, this is not as simple as it may appear, because rice that has been left for an extended period of time can grow germs and cause food poisoning when consumed.

If you want to know how long you should keep rice in a rice cooker before cooking, then read our article below:

What Is a Rice Cooker?

A rice cooker is a kitchen appliance designed specifically to help us cook rice easily and effectively. These appliances come in different sizes and shapes depending on what type of rice we wish to cook.

There are also models available that allow us to choose from various types of rice such as brown or white rice. Some even include features like timers so that we don’t forget about our meals while we go out.

How Long Should Rice Be Left in a Rice Cooker?

The first thing we must consider here is whether or not you really need to clean your rice cooker after each use. Some people think that keeping rice inside the rice cooker means that it’s safe from contamination. But this isn’t true at all!

There are many things that could contaminate your rice such as dust particles, grease, oil, etc. These contaminants can easily get into your rice cooker through the air vents. Even though your rice cooker might be sealed tightly, it still needs regular maintenance so that no dirt gets stuck between the vent holes. The best solution would be to wash your rice cooker thoroughly once a week. Make sure to wipe down the entire interior including the lid and base.

Also, don’t forget about the heating element underneath the lid. Cleaning up any residue around the heating elements will also help prevent fires.

Rice in the keep warm mode generally lasts 11-12 hours; after that period, germs may grow and the flavour may deteriorate. It’s true that certain rice cookers are better than others at keeping rice, especially luxury ones like the Cukoo Crp. Rice may survive a few hours longer in this rice cooker than in others.

Is Rice Safe to Leave Overnight?

You probably already knew that rice can last overnight but did you know that it actually tastes better if cooked right after being prepared? That’s why most chefs recommend leaving rice out of the fridge for 24 hours before serving.

After that amount of time, the starch molecules within the grains begin to absorb water and expand. As a result, the texture becomes softer and more tender. So yes, rice can definitely be kept overnight in the refrigerator. Technically, yes; nevertheless, it is not advised. Leaving rice in the rice cooker overnight can result in the rice changing colour and losing its flavour, which is an indication that bacteria is developing. Take a small amount of rice and taste it; if it has an off-putting flavour, don’t eat it; instead, throw it away or use it for something else.

Is it True that Reheating Rice Kills Bacteria?

It depends on what kind of bacteria there was in the first place. If the rice had some sort of bacterial infection, then re-cooking won’t kill them.

On the other hand, if the rice didn’t have any bacteria present, then re-cooked rice shouldn’t contain any harmful microorganisms either. This is one reason why it’s important to always follow proper cleaning procedures with your rice cooker. No, warming the rice will not destroy the bacteria if it has already multiplied, and there is no way of knowing if the rice is safe to eat. According to studies, properly storing and reheating rice is critical in preventing food illness.

How to keep leftover rice fresh?

If you’re planning to save leftover cups of rice for later consumption, here are two ways: 1) Refrigeration – Store leftovers in the refrigerator for 3 days. 2) Freezing – Freeze leftovers immediately after cooking. Once frozen, they should remain good for 6 months.

The best and safest way to store leftover rice is to turn off the rice cooker after 5 hours, remove the rice, and store it in a sealed container in the refrigerator (make sure the container is fully closed). To preserve the rice as fresh and flavorful as it was initially prepared, I recommend steaming instead of using the rice cooker. This way you can preserve leftover rice.


There isn’t really much scientific evidence regarding how long we should let rice sit in our rice cooker. However, based on my own experience, I would say that it’s perfectly fine to leave rice in the rice cooker until it gets mushy or sticky rice.

The only thing you need to watch out for is when the rice starts smelling bad. When that happens, just toss it out.
