Lentils can be cooked in a rice cooker only when its manual allows legumes and provides a suitable method. Lentils can foam and expand, so a water ratio alone does not make every rice cooker suitable. Otherwise use a saucepan or an appliance designed for the recipe.
Steps to Prepare Lentils in A Rice Cooker
There are different types of lentils, and the cooking process for each of them varies slightly.
Use these general preparation notes only with an appliance-approved lentil recipe; follow its program, batch size and water amount.
1. Measure and Rinse the Lentils
It’s necessary to accurately measure the lentils to add the correct amount of water for cooking them.
Rice cookers come with a measuring cup. You can use this cup to measure the lentils.
Measure water according to the approved lentil recipe; rice water marks are not automatically correct for legumes.
After measuring the lentils, wash, and rinse them well to remove any dirt or dust on the surface.
2. Measure the Accurate Amount of Water
Use a lentil-specific water mark only if the cooker provides one. Do not use a plain-rice mark for lentils by default.
The water amount depends on the lentil variety, recipe and cooker. Do not substitute a universal ratio for the approved method.
After adding the water, let the lentils soak in it. This step is optional. But soaking will soften the lentils and help them cook faster.
So you can cut down on the cooking time.
3. Transfer the Lentils to The Rice Cooker
Add the lentils and water to the rice cooker. You can replace water with broth or stock if you prefer. This will make the dish richer and more flavorful.
Follow the model’s limit for foaming foods, which may be lower than its rice capacity. Never block the steam outlet.
After adding the liquid, season the water with salt.
If you wish to add other aromatic herbs or spices, like garlic or pepper, you can add them now. Then close the lid of the rice cooker.
Plug it in and enable the cooking function. Most rice cookers will not have a dedicated setting for lentils.
If there is no approved lentil program or method, do not guess at a rice or high setting. Cook the lentils using a suitable alternative appliance.
4. Follow the Approved Cooking Method
Cooking time varies with the lentils and appliance. Follow the manual’s supervision instructions rather than relying on a fixed time.
Stirring is appropriate for some recipes but not for every cooker.
Stir only if the model and recipe permit opening during cooking. Never open or force the lid of a pressurized cooker to stir.
5. Check Doneness and Serve Safely
An automatic switch at the end of a cycle does not by itself prove that lentils are tender. Follow the approved recipe and check the result safely.
Some models switch to Keep Warm after cooking; others operate differently.
Once the lentils are fully cooked, serve them hot or use the safe holding and storage guidance below.
A Keep Warm label does not establish safe holding for lentils. Use it only if the manual permits the dish and the food remains at 140°F or above.
Storing the lentils at room temperature for too long will trigger microbial growth and lead to faster spoiling.
If safe hot holding is not available, divide the lentils into shallow containers and refrigerate promptly, within two hours or one hour above 90°F.
How to Reheat Lentils in A Rice Cooker?

Do not use an ordinary Keep Warm setting to reheat cold lentils. It is intended to hold already-hot food, and may heat chilled leftovers too slowly.
Reheat lentils on the stovetop or in a microwave to 165°F throughout, stirring for even heating. If using a cooker’s dedicated reheat function, its manual must explicitly allow that food and method; check the final temperature.
Refrigerate leftovers promptly in shallow containers and keep them at 40°F or below. Thaw frozen lentils in the refrigerator, or use an appropriate cooking or reheating method directly from frozen.
After reheating, serve promptly or keep the food at 140°F or above in equipment approved for hot holding.
Common Problems to Consider When Cooking Lentils in A Rice Cooker
The process of cooking lentils in a rice cooker is simple. Nevertheless, you can improve the outcome with a few extra precautions.
Let’s look at what they are.
1. Soak the Lentils
Soaking the lentils softens them because they absorb water and expand in size. The main benefit is that it speeds up the cooking process.
Firm lentils may need longer soaking than small and soft lentils.
Many lentils do not need soaking. Follow the lentil package and the approved recipe instead of assuming an overnight soak is required.
2. Use the Right Amount of Water
Use the water amount in a recipe approved for your cooker and lentil variety.
Different lentils can produce a firm or softer result and may need different amounts of liquid.
Adjustments should stay within the model’s capacity and instructions for foaming foods.
Additionally, you may also have to adjust the ratio depending on the rice cooker. Check the manufacturer instructions with the appliance for a guideline.
3. Stir Only When Permitted
Follow the cooker’s supervision and stirring instructions. Do not lift a pressure lid during operation.
When stirring is permitted, it can help distribute heat and reduce sticking. It does not replace the correct water amount and cooking method.
4. Allow the Lentils to Rest
After cooking, we advise waiting for a few minutes before serving the lentils.
Keeping the lid on for a few extra minutes will allow the lentils to absorb any remaining moisture. It also allows the flavors to blend in better.
You can open the lid and serve the lentils after waiting for five to ten minutes.
