Why Zojirushi Rice Too Sticky: 6 Reasons And Remedies

It is well known that Zojirushi rice cookers produce high-quality, perfectly cooked rice. Zojirushi rice cookers may produce sticky rice for a variety of reasons. 

Reasons Remedy

Overcooking the rice Cook with exact time 
Deformation of the Inner pan and inner lid Replace the deformed part
Incorrect menu selection Select the correct menu 

Zojirushi Rice Too Sticky – Reason 1: Improper Water Ratio 

The most common reason for Zojirushi rice to become sticky is due to too much water.  Too much water can cause rice grains to become overly saturated with moisture, making them sticky and soft.

In this case, excessive water can lead to rice grains breaking down and releasing more starch, resulting in sticky rice. Conversely, if you don’t use enough water, the rice may be undercooked and have a drier texture. 


The water-to-rice ratio is a critical factor in determining the texture of cooked rice. Be sure to use the right amount of water to avoid sticky Zojirushi rice.

The ideal water-to-rice ratio varies depending on the type of rice, age, and how the rice cooker is configured. Let’s look at the following chart for proper water measurement of different types of rice. Please use the same measuring cup when measuring rice/grains and water.

Rice TypeWater (per cup of rice)
Short/Medium Grain (White)1 cup
Short/Medium Grain (Brown)1 ½  cup
Long Grain (White)1 ¼ cup
Jasmine (White)1 ¼ cup
Basmati Rice (White)1 ½  cup
Wild Rice 1 ½  cup
Quinoa1 ¼ cup
Rolled Oats1 ½  cup
Steel Cut Oats2 ½  cup

To achieve the best texture from your cooked Zojirushi rice, adjust the water ratio accordingly. You can use the green or white Zojirushi cup depending on the rice you want to cook.

Zojirushi Rice Too Sticky – Reason 2: Inappropriate Rice Rinsing

The next potential reason for sticky Zojirushi rice is not rinsing the rice properly. If you don’t properly rinse your rice before cooking, you may end up with stickier rice due to excess starch.

So, if you don’t thoroughly rinse your rice, or skip this step altogether, your Zojirushi rice will be sticky eventually. 


To prevent the grains from clumping together, rinse the rice to remove excess starch. A sticky, mushy, or porridge rice is the result of loosened starches that are not washed off.

Rinse the rice thoroughly before cooking to achieve the desired texture if you’re using a Zojirushi rice cooker. Make sure to remove all the debris and extra starch contained in the rice. Rinsing is necessary even if you cook boxed rice in a rice cooker

Please follow the instructions below in order to rinse the rice properly.

  • First, place the rice in a large bowl of cold water before cooking.
  • Then, use your hand to swirl the rice and drain the murky water.
  • Repeat the process 2-3 times until the water comes out clean.

Zojirushi Rice Too Sticky – Reason 3: Fluffing the Rice Instantly after Cooking

The next culprit for having sticky Zojirushi rice is fluffing the rice immediately after cooking the rice. The Zojirushi rice becomes sticky if you don’t allow it to rest for a specified amount of time after it is cooked. Resting time allows the trapped steam to escape the cooker so it doesn’t affect the rice.

Even after the cooker informs you that the rice is cooked, the rice is usually still left with some extra moisture. If you fluff the rice in this condition, you’ll have sticky rice for sure. 


Before fluffing the rice after the cooker tells you it’s done, allow it to rest for a few minutes. It is recommended that you let the rice rest for 15-30 minutes before fluffing it. You can do it properly by following the instructions below.

  • Take a rice paddle to gently fluff the rice from the cooker. Remember, forks and spoons can break rice grains, so avoid using them.
  • Finally, make sure the cooker is left open after fluffing the rice to allow excess moisture to escape. 

Zojirushi Rice Too Sticky – Reason 4: Overcooking

Cooking rice for too long or on too high a heat can also cause it to become sticky. The starch granules of the rice can break down at too high a temperature or for longer cooking and release their starch into the surrounding water. 

This excess starch can then be absorbed back into the rice grains, causing them to become sticky and clump together.


Knowing the duration to cook rice in the rice cooker is a must-have knowledge for any person. So, stop overcooking the rice, if you do it quite often. 

Always follow the Zojirushi rice cooker’s manual to know the exact time of cooking. 

Let’s look at a chart for the recommended time according to the manual.  

Type of RiceRecommended Time 
White rice40- 49 minutes
Mixed rice52-58 minutes
Brown rice1 hour 20 minutes – 1 hour 38 minutes
GABA brown rice3 hours 14 minutes – 3 hours 33 minutes

Zojirushi Rice Too Sticky – Reason 5: Deformation of the Inner Pan Or Inner Lid 

Deformed inner pans or inner lids of a Zojirushi rice cooker can cause gaps or uneven surfaces that prevent proper steam circulation during cooking. As a result, the steam will not be distributed evenly throughout the chamber, causing the rice to become sticky and clumpy.

Generally, steam is generated by heating water in the outer pot of the rice cooker. The steam rises up into the inner pan or pot, where the rice is placed. 


Inspect the inner pan or inner lid regularly for deformation and replace them if they become damaged or deformed. Check the official website to buy replacement parts.

Zojirushi Rice Too Sticky – Reason 6: Incorrect Menu Selection

Choosing the wrong cooking menu on your rice cooker can result in overcooked or undercooked rice, which can be sticky. Rice cookers typically have different cooking modes or menus to accommodate different types of rice and different water ratios.

So, if you choose a menu that calls for a longer cooking time or a higher water ratio than what is needed, the rice may become mushy and sticky.


To prevent sticky rice caused by selecting the wrong cooking menu, it’s important to carefully read the instructions. There you’ll get to know your rice cooker’s options. Then you must select the appropriate menu for the type of rice you are cooking. As an example, don’t select brown rice settings while cooking white rice.
