Stovetop Boiling Time for Mung Beans
For most home cooks, the stovetop is the most common way to boil mung beans. The process is straightforward, but the time can vary. To start, rinse your mung beans thoroughly in a colander to remove any dust or debris. This is important whether you plan to soak them or not. After rinsing, the cooking time will depend on your preparations.
For unsoaked, whole mung beans:
- Bring a pot of water (a ratio of 1 part beans to 3 parts water is a good starting point) to a boil over high heat.
- Add the rinsed mung beans and return to a boil.
- Reduce the heat to a simmer and cook for approximately 30 to 45 minutes, or until the beans are tender. Some beans may split during this process, which is normal.
For pre-soaked, whole mung beans:
- Soaking mung beans for 8 to 12 hours can significantly cut down the cooking time.
- After soaking and rinsing, bring a pot of water to a boil and add the beans.
- Simmer for about 20 to 30 minutes, or until they reach your desired tenderness.
- The soaked beans will cook more evenly and produce a creamier texture.
The Impact of Soaking Mung Beans
While not strictly necessary for cooking, soaking has distinct benefits. Soaking not only speeds up the cooking time but can also aid in digestibility. It helps to break down complex sugars that can cause gas and bloating. While unsoaked beans will cook up fine, soaked beans often result in a more consistently tender product, which is ideal for creamy dishes like dal or soup.
Cooking Mung Beans with a Pressure Cooker
For those who need to cook mung beans quickly, a pressure cooker is the fastest option. This method drastically reduces the time required and is perfect for busy weeknights.
- For unsoaked, whole mung beans: Add 1 cup of rinsed beans and 3 cups of water to the pressure cooker. Cook on high pressure for 3 to 5 minutes. Allow for a 10-minute natural pressure release before opening. If you want a softer consistency, increase the cooking time slightly.
- For pre-soaked, whole mung beans: Use the same 1:3 ratio of beans to water. Set the pressure cooker for 0 minutes on high pressure, with a 5 to 10-minute natural pressure release. The time it takes to reach pressure is enough to cook the already-softened beans.
Split Mung Beans vs. Whole Mung Beans
It is important to differentiate between whole green mung beans and split, hulled mung beans (often called moong dal). Split mung beans cook much faster because their tough outer layer has been removed. They are ideal for thickening soups and curries, as they break down easily.
- Stovetop cooking for split mung beans: Simply boil them in a 1:2.5 ratio of beans to water for about 15-25 minutes, or until tender.
Mung Bean Cooking Methods Comparison
| Method | Soaking Recommended | Estimated Cooking Time (Whole, Unsoaked) | Estimated Cooking Time (Whole, Soaked) | Best for... |
|---|---|---|---|---|
| Stovetop | Optional, but speeds up cooking | 30–45 minutes | 20–30 minutes | Soups, salads, general use |
| Pressure Cooker | Optional, but helpful | 3–5 minutes (plus pressure release) | 0 minutes (plus pressure release) | Fast cooking, creamy dal |
| Slow Cooker | Not necessary | 3–6 hours (high/low) | 2–4 hours (high/low) | Hands-off cooking, stews |
Advanced Tips for Boiling Mung Beans
To achieve the best results, consider these additional tips:
- Rinse thoroughly: Always rinse your mung beans multiple times before cooking to remove any dirt or debris. The water should run clear.
- Salt at the end: Adding salt at the beginning of the cooking process can sometimes toughen the skins of the beans. It is best to add seasoning toward the end of the cooking time for the most tender texture.
- Don't overfill the pot: When using a pressure cooker, never fill it more than halfway with beans and water to allow for proper pressure buildup.
- For thicker consistency: If you're making a dal or soup and want a thicker, more porridge-like consistency, slightly increase the cooking time or use an immersion blender to break down some of the cooked beans. Adding baking soda can also help soften the beans faster.
Conclusion
The time it takes to boil mung beans depends heavily on the method you choose and whether you opt for presoaking. A stovetop simmer will take the longest at 30-45 minutes for unsoaked beans, while a pressure cooker can finish the job in a fraction of the time. For salads and recipes where you want the beans to hold their shape, monitoring the stovetop method carefully is best. For creamy dals and soups, a pressure cooker or longer boil will provide the desired soft texture. By following these guidelines, you can ensure perfectly cooked mung beans for any dish.

Key takeaways
- Stovetop Time: Unsoaked mung beans take 30-45 minutes to boil on the stovetop, while soaked beans reduce the time to 20-30 minutes.
- Pressure Cooker Speed: A pressure cooker significantly speeds up the process, with unsoaked beans cooking in 3-5 minutes and soaked beans in 0 minutes (plus natural release time).
- Soaking is Beneficial: Soaking mung beans for 8-12 hours before cooking can improve texture and aid digestibility, though it's not required.
- Whole vs. Split: Whole mung beans have their hull and take longer to cook than split, hulled mung beans (moong dal), which are faster and ideal for creamy dishes.
- Salt Timing: For the most tender results, add salt and other seasonings toward the end of the cooking process rather than at the beginning.
FAQs
Question: Do you have to soak mung beans before cooking? Answer: No, you do not have to soak whole mung beans before cooking, especially if using a pressure cooker. However, soaking can reduce the stovetop cooking time and improve the texture of the finished beans.
Question: How can I cook mung beans faster? Answer: The fastest method to cook mung beans is using a pressure cooker. For unsoaked beans, cook for 3-5 minutes on high pressure. Soaking them beforehand and then using a pressure cooker for 0 minutes (plus a 10-minute natural release) is also incredibly fast.
Question: What is the best ratio of water to mung beans for boiling? Answer: A standard ratio is 1 part mung beans to 3 parts water. This can be adjusted based on your desired consistency. Use less water for firmer beans or more for a softer, soupy texture.
Question: How long does it take to boil split mung beans (moong dal)? Answer: Split mung beans cook much faster than whole beans. On the stovetop, they typically only need 15-25 minutes to become tender. A pressure cooker will cook them even faster.
Question: How do I know when my mung beans are done cooking? Answer: Mung beans are done when they are tender and have lost their hard, grainy texture. For soups, some of the beans will have burst and created a creamy consistency. For salads, they should be soft but still hold their shape.
Question: Can I cook mung beans in a slow cooker? Answer: Yes, you can cook mung beans in a slow cooker. For a hands-off approach, add 1 cup of beans and 3 cups of water and cook on high for 3 hours or low for 6 hours.
Question: What are the signs of overcooked mung beans? Answer: Overcooked mung beans will turn very mushy and lose their individual shape, resembling a thick paste. While this is desirable for some dishes like dal, it's not ideal for salads or when you need the beans to stay intact.
