Zojirushi rice cookers are designed to make cooking rice effortless. They have advanced features and technology that automatically adjust while cooking. Sometimes, however, you may find that your rice turns out dry instead of moist and fluffy.
If your Zojirushi cooker produces dry rice, there could be several reasons. You may need a different rice ratio to water. Or, you might select the wrong program when setting up the cooking process. It’s also possible that the silicone gasket or lid is not sealing correctly or that some of the internal parts of your appliance are malfunctioning.
Why Is My Rice Always Dry In My Zojirushi Rice Cooker?
If you cook rice in your Zojirushi and it comes out dry, it may be because:
- The seal or silicone gasket doesn’t seal correctly. If the gasket releases moisture during cooking, your rice will dry. Contact the manufacturer for a replacement seal.
- You don’t have the correct rice-to-water ratio. If you don’t add enough water or broth, your rice will come out dry.
- Your machine cooks at too high of a temperature. The heating element may have worn out, or another internal issue may exist. Contact the manufacturer.
- The inner lid isn’t attached correctly. If the top isn’t properly placed, your machine won’t seal properly.
- You chose an incorrect program for cooking. Select the program Zojorushi recommends according to the type of rice you are cooking. If you select a different program, your rice may not cook properly and dry out.
Why Does My Zojirushi Rice Cooker Dry Out My Rice On Warm Mode?
If your rice becomes dry after cooking, you may use the Warm Setting too long. You should only keep your rice warm for a few hours. After that, cool it and store it in the fridge.
Some Zojirushi rice cookers can keep rice warm for days. But, the manufacturer doesn’t recommend keeping rice warm for that long. Your rice will dry out over time and start to spoil.
Keep Warm settings work better with larger quantities of rice. If you try to keep one or two cups of rice warm, it will dry out. You may be more successful at keeping three or more cups warm.

How To Make Perfect Rice In Your Zojirushi Rice Cooker
Zojirushi rice cookers cook best with a 1:1 rice-to-water ratio, meaning you add one cup of water for every cup of rice. I follow the steps below for perfect rice every time:
- I measure my rice using the cup that came with my rice cooker. This cup is 180 ML or ¾ US cup.
- I rinse my rice under running water for 30 seconds. I make sure each grain gets rinsed to remove excess starch. Then, I add the rinsed rice to the inner pot.
- I fill the pot with water to the appropriate line. For example, if I measure two cups of dry rice, I fill the pot to the two-cup line with water.
- I select the appropriate program based on what type of rice I’m cooking.
- After my rice finishes, I let it rest for 5-10 minutes on Keep Warm. Then, I fluff it with a fork before serving.
How To Store Uncooked Rice

The perfect pot of rice starts with the storage of your dry rice. If you leave your rice in bags in your pantry, it may spoil before you cook it. The fresher you keep your uncooked rice, the better it will cook in your rice cooker.
I store my rice in airtight containers to keep it fresh as long as possible. I usually buy rice in bulk and package it for the pantry or freezer that same day.
I set aside enough brown rice for one month in an airtight container. I put extra brown rice in freezer bags. Brown rice stays fresh for about 18 months in the freezer. White rice has a longer shelf life, but I still prefer to freeze what I won’t need for the month. Freezing rice helps it stay fresher for longer.
How Do You Fix Undercooked Rice In A Zojirushi Rice Cooker?
If you find your rice to be dry and undercooked, try these ideas:
- Next time you cook rice, add more water. Try using one cup of rice to 1 ¼ cup of water or broth. This extra moisture will stop your rice from drying out.
- Add butter or oil to your rice before cooking. Measure your rice and water as usual. Then, add 2 TBSP of butter or oil per cup of rice.
- Check on your rice as it cooks. Open the lid after 15-20 minutes and look at your rice. If all the water is absorbed, pour in ¼ cup hot water to give your rice more moisture.
- Add broth to your cooked rice. If you discover your rice is dry after cooking, pour in ¼ cup of broth for each cup of rice. Stir to combine. Broth adds moisture and flavor, improving the texture and taste of your rice.
One other method is to add vinegar to rice before cooking. Vinegar helps soften rice grains as well as adds flavor.
The acetic acids in vinegar help break down the starches in your rice, creating a fluffy texture. It also adds a slightly acidic or sour flavor, which compliments the nuttiness of rice. I often add vinegar to Sushi rice, Korean bibimbap, and Chinese fried rice.
The next time you make a pot of rice, add one teaspoon of vinegar for each cup of dry rice. Both apple cider vinegar and white vinegar work well.
Final Thoughts
Zojirushi rice cookers are premium-brand cookers made to cook rice perfectly. If your rice is dry after cooking, add more water or butter next time. If your rice is consistently dry, contact the manufacturer, as your appliance may be defective or have failing internal parts.
