How to Make Yogurt in a Rice Cooker

Making yogurt at home sounds complicated, but once you learn how to make it in a rice cooker, it becomes one of the easiest kitchen projects you can try. A rice cooker provides steady heat, controlled temperature, and a closed environment that helps milk ferment into smooth, tangy yogurt. 

This method works even if you don’t own a yogurt maker, slow cooker, or oven. All you need is milk, a starter culture, and patience.

Not Just for Eating Rice: Why Rice Cookers Work For Yogurt Fermentation

A rice cooker is ideal for yogurt because it can:

• Maintain low, steady heat
• Use a warm setting for fermentation
• Keep the pot covered with a lid
• Avoid high heat once the culture is added

You can use an Aroma rice cooker or any electric cooker with a “warm” menu. Even basic models without special yogurt settings work. 

The key is temperature. Yogurt bacteria thrive around 110°F (43°C). Too much heat kills the culture, and too little heat slows fermentation.

Homemade Yogurt Recipe: Step-by-Step Cooking and Fermentation Process

Heat the milk properly

Pour milk into the cooker bowl. Use the cook or steam setting until it reaches near boil (about 180°F). Stir the milk gently to prevent sticking.

Cool the milk to the right temperature

After boiling, remove the pot, cover it, and wait until the remaining milk cools to about 110°F. Regularly measure the temp using athermometer. If the milk is too hot, it will destroy the culture immediately. 

Mix in the yogurt starter culture

In a cup, begin to mix a small portion of warm milk with the yogurt starter. Whisk until smooth. Pour back into the pot and stir gently. 

Close the lid and allow fermentation

Place the cooker bowl back in the rice cooker. Press the warm setting. Close the lid and leave it for 6–8 hours without stirring. 

Check texture and whey separation

The yogurt should appear thick with some whey on top. For thicker yogurt, leave it for longer or strain the whey. 

Refrigerate the finished yogurt

Transfer into containers and refrigerate for at least 2 hours before eating.

How Yogurt Fits Into Rice-Based Meals

Yogurt pairs well with rice-based dishes. In Korea and other Asian cultures, yogurt is often enjoyed to cool the palate and support digestion after spicy or heavy meals. 

You can serve yogurt with:

• Steamed rice and fruit
• Honey and nuts
• As a side dish
• In smoothies or baked recipes

This makes your rice cooker useful beyond just cooking rice.

Tips for Thicker Yogurt and Improved Flavor

• Use whole milk
• Add powdered milk for thickness
• Strain whey using cheesecloth
• Do not stir the milk and starter while fermenting
• Let yogurt sit longer for tangier flavor 
• Transfer to containers and refrigerate immediately after fermentation

Flavor the milk and starter after fermentation using: 

• Honey
• Fruit
• Vanilla
• Cinnamon

Avoid adding sugar to the milk and starter during fermentation because it can interfere with the culture.

Storing and Reusing Yogurt Batches 

• Store in airtight containers in the refrigerator
• Keeps fresh for 7–10 days
• Save 2 tablespoons as starter for the next batch
• Wash the cooking bowl thoroughly between batches

Each batch can be reused to create the next one.
