You can actually learn this fast enough so you can cook your own meals. How to cook it varies depending on the way you choose to do it: some use the traditional cooking pot, others use the convenient electric rice cooker; while others go for oven-cooked or stove top kind of cooking rice. Below is the simple steps to prepare uncooked rice grains, using an electric rice cooker:


  • 1An electronic rice cooker, a stainless pot or earthen pot (for the traditional way of cooking) to cook rice in. You may also use a stovetop or oven for this one.
  • 2A measuring cup
  • 3Distilled water or plain water to pour in the uncooked rice for boiling
  • Make sure the rice cooker is properly cleaned and the bottom surface must be dry.



Make sure the rice grains are free from mold, moisture or rice insects. Check for the quality of the rice grains before cooking.

You may also rid the rice grains of little specks of dirt like unopened grains or kernels before cleansing the grains with water.

Below is an example of how to cook white milled rice using an electric cooker:

Step 1

Pour one (1) cup of rice in the rice cooker.

  • One cup of rice is good for two persons for light eaters.

Step 2

Fill the rice cooker or pot with enough distilled water (about 4-5 cups).

Step 3

Cleanse the uncooked rice using distilled water, moving in a gentle circular motion to float the unwanted specks or unopened grains from the white rice. Then pour out the rice water.

Step 4

Fill the electronic rice pot with water.

  • One cup of white rice is equal to one cup of water. Two cups of rice are equal to two cups of water. Follow the 1:1 rule

Step 5

Insert the plug into the electric outlet. The rice cooker’s signal light will be lighted once it’s turned on.

Step 6

You’ll know the rice is cooked when the rice grain has enlarged and turned soft enough to be eaten.

Step 7

Served hot during a meal, or top the cooked white rice with your favorite dish.


A cup of DRY rice grains for cooking would usually expand three times after cooking.

1 cup = about 200 grams

2 cups = 400 grams

3 cups = 600 grams

Note: Depending on how much you prefer, one cup is usually good for one to persons/ serving.

How Long Will Cooked Rice Last Unrefrigerated?

We know that food can get bad when left unrefrigerated. So does rice.

Cooked rice will remain good for as long as it’s served hot. But after eating, it should not be left out in the open without proper storage.

This is to keep bacteria from growing. If you must know, what grows in cooked rice is called-Bacillus cereus. It’s a kind of spore that’s resistant to heat.

But it’s not actually the one you have to remember. Spoilt rice can cause food poisoning.

According to an article published in, spores “can germinate…and produce toxins” in cooked rice when “left at room temperature..”, (Berkeley Wellness).

So, better serve your rice within hours as soon as it’s cooked and done, to avoid the risk of contamination or spoilage.

How To Properly Store Cooked Rice

Put some cover in the left-over or unused rice. Place them in a tightly-lid container preferably made of glass or durable plastic ware.

And then store it is in the refrigerator where it must be kept at below 4 degrees Celsius.

You may also store it in the freezer which can make the cooked rice last longer.

Why It’s Important To Handle Rice Properly

Aside from spoilage, mishandling food such as rice can not only cause illness.

It can also change the quality and taste of rice just like other foods when these are not properly prepared or shelved.

Below are some examples which can affect the quality and taste of cooked rice:

  • Improper food storage of the dry rice
  • Putting too much water in the rice prior to cooking
  • Too short or too long cooking time
  • Placing the left-over cooked rice in the wrong container or outside the refrigerator
  • Not serving the freshly-cooked rice as soon as it’s ready

Can Cooked Rice Be Reheated Properly?

Yes, you may. Why not try to re-cook your rice in the pan and turn it into a new rice recipe?

Perhaps out of the plain cooked rice, you can also add some herbs or left-over meat strips and vegetables. Now that’s instant fried rice for you.

Ways to Reheat Cooked Rice

You may try the following ways to warm your cooked rice which has been placed in the refrigerator, by:

  • Cooking again over pan (see below a sample recipe)
  • Reheating over microwave – programme the control button on medium heat and set to 1-2 minutes for 1-2 cups of cooked rice to be reheated. A too long or too high setting in the microwave can dry out the cooked rice.
  • Reheating over stovetop

A sample of rice recipe from repurposed or left-over rice using the pan to re-cook the rice:


  • 1Cooking oil (preferably olive oil, vegetable, canola or sunflower oil)
  • 2A few garlic cloves
  • 3Green peas in a can
  • 4Shredded vegetables or meat (some food leftover)
  • 5A teaspoon of oyster sauce to add flavor and twist
  • 6Salt and/or seasoning


  • 1Warm the pan and put the oil.
  • 2Heat the cooking oil
  • 3Toss in the garlic cloves. Wait until golden brown.
  • 4Put the peas, mixed veggies or any leftover food ingredients you want to be included.
  • 5Saute until cooked.
  • 6Put in the mashed leftover rice. Mix together.
  • 7Flavor the fried rice with a tablespoon of oyster sauce.
  • 8Sprinkle with some salt and seasoning to taste.

How to Tell If A Cooked Rice Is Still Good

Here are some cues on whether a cooked rice needs to be tossed away already:

Touch – Does it look a little watery, softer or mushier when first cooked?

Sight – The color of the rice looks off-white or has turned discolored.

Smell – Does it have a pungent or odorous scent?

Taste – Does it taste bad or has its taste changed?

So Really, How Long Is Cooked Rice Good?

So it really depends on how you cook the rice, where you store it, and how soon you keep it from getting wasted.


  • The rice grains have been stored improperly and had contaminants prior to cooking (rice insects, moist, etc).
  • It’s been overcooked or undercooked.
  • t’s been frozen or kept too long in the fridge (two days or more in the ref would change the quality of the cooked rice already). For freezer-kept cooked rice, if it’s been stored for six months or more, this could already change the quality of the cooked rice.
  • It wasn’t covered or placed in a proper container before cooling.
  • The rice wasn’t allowed to cool down before storing in the container and was placed in the ref immediately.


It has become soggy, watery, dry, clumped together or its color has changed from the original color when it was first cooked.  The rice can also have an unpleasant smell.

People ask questions:


This depends on the weather conditions, sunny or winter.

But the safest rule of the thumb is to serve your cooked rice only a few hours within a day and preferably within an hour or two, after cooking.

Untouched cooked rice must be covered in a container or placed in appropriate storage.

Make sure also that plain cooked rice must be cooled down a bit before covering or storing.

Being aware of how to properly cook rice, store it and repurpose it can help you make good use of your kitchen ingredients such as rice which is a pantry staple for many.

And of course, if you like serving rice meals, and is a certified rice-buff, then it’s important to know some of this basic information.

Food handling counts a lot in keeping the cooked rice fresh. And remember to serve your cooked rice soon enough.
