Legume sprouts such as chickpeas, lentils, peas and mung beans are larger and more substantial than delicate leafy sprouts. They develop crisp roots and shoots with mild, earthy, nutty or sweet flavours and can be grown indoors in a jar with very little equipment.
Unlike leafy sprout blends, however, different legumes can vary considerably in seed size, soaking time and harvest timing. For the most consistent results, grow each legume variety in its own jar and combine the finished sprouts after harvest.
Which Legumes Can You Sprout?
Popular legumes for home sprouting include:
- Chickpeas – large, firm and mildly nutty
- Lentils – smaller, earthy and crisp
- Field peas – sweet, mild and substantial
- Mung beans – crisp, juicy and slightly sweet

Legume Sprouting Times at a Glance
| Legume | Approx. Seed per 500ml Jar | Soak Time | Typical Harvest |
|---|---|---|---|
| Chickpeas | About 5 tbsp | 8–12 hours | 3–6 days |
| Lentils | About 3 tbsp | 10–12 hours | About 2–6 days, depending on variety |
| Field peas | About 3 tbsp | 8–12 hours | 2–4 days |
| Mung beans | About 5 tbsp | 8–12 hours | 3–5 days |
These figures are practical guides based on the current OzSprout growing information for these crops. Always follow the product-specific instructions for the exact variety you are growing.
How to Grow Legume Sprouts
1. Clean Your Sprouting Jar
Wash your hands, sprouting jar, lid and any utensils thoroughly before starting.
Legumes are relatively large seeds and can hold moisture between them, so clean equipment, good drainage and airflow are particularly important.
2. Measure & Rinse the Seeds
Choose one legume variety per jar and measure the appropriate quantity for that crop.
Do not fill one-third of the jar with dry seed. Chickpeas, peas, lentils and mung beans expand substantially during soaking and need plenty of space for rinsing and airflow.
Rinse the dry seed thoroughly with clean, drinking-quality water and remove any visibly damaged or discoloured seeds.
A Glass Sprouting Jar is useful for large legume seeds because soaking, rinsing and draining can all be done in the same container.
3. Soak for the Correct Time
Cover the seeds generously with fresh water and soak according to the variety.
As a general guide:
- Chickpeas: 8–12 hours
- Lentils: approximately 10–12 hours
- Field peas: 8–12 hours
- Mung beans: 8–12 hours
Use a large enough container because legumes absorb considerable water and expand during soaking.
After soaking, drain all of the water, rinse once more and drain thoroughly.
4. Rinse & Drain 2–3 Times Daily
Rinse the developing sprouts approximately 2–3 times each day with cool or room-temperature drinking-quality water.
After every rinse:
- Drain the jar completely.
- Position it at an angle so excess water can escape.
- Keep the opening clear for airflow.
- Avoid hot direct sunlight.
- Never leave the legumes sitting in standing water.
There is no need to use warm water to make the seeds sprout faster. Good hydration, drainage, airflow and a stable indoor temperature are more important.
5. Harvest When the Sprouts Suit Your Taste
Legume sprouts are usually harvested relatively young, while the shoots remain crisp and the seed itself is still substantial.
Depending on the crop, sprouts may be ready within approximately 2–6 days.
Shorter sprouts tend to have a firmer, crunchier texture, while longer growth produces more developed shoots.
Give the finished sprouts a final thorough rinse, remove any damaged or unsprouted seeds and drain well before refrigeration.
Should Chickpeas, Lentils & Peas Be Sprouted Together?
It is better to sprout them separately.
Although chickpeas, lentils and peas are all legumes, they differ in:
- Seed size
- Water absorption
- Recommended seed quantity
- Soaking time
- Harvest timing
- Texture at the ideal harvest stage
Growing them separately lets you give each variety the conditions it needs and harvest each crop at the right time.
If you want a mixed legume sprout bowl, simply combine the different sprouts after they have been harvested.
Tips for Growing Legume Sprouts Successfully
Leave Plenty of Room in the Jar
Legumes expand significantly after soaking. Overfilling the jar restricts airflow and makes effective drainage more difficult.
Drain Thoroughly
Large seeds can trap water between them. Tilt the jar after every rinse and allow as much excess water as possible to escape.
Maintain Good Airflow
Keep the sprouter in a well-ventilated indoor location rather than a sealed cupboard or hot, humid space.
Do Not Force Faster Germination
Avoid hot water and excessive warmth. A stable indoor temperature and regular rinsing are more reliable than trying to accelerate growth.
Remove Damaged Seeds
Large legumes are easy to inspect. Remove seeds that remain unusually hard, become discoloured or show signs of deterioration.
How Do You Know When Legume Sprouts Are Ready?
Harvest timing depends on the crop and the texture you prefer.
Look for:
- Visible healthy root growth
- Firm, crisp seeds
- A fresh appearance
- A clean, mild smell
Lentils and peas may be enjoyable with relatively short roots, while chickpeas can be allowed to develop slightly longer shoots.
What If My Legume Sprouts Smell Sour or Feel Slimy?
Healthy legume sprouts should smell fresh and have a firm texture.
Discard the batch if you notice:
- Sour, rotten or strongly musty odours
- Slime
- Soft or decaying seeds
- Unusual discolouration
- Persistent mould-like growth
Do not attempt to rinse away obvious spoilage.
Legume Sprout Food Safety
Raw sprouts require careful food handling because the warm, humid conditions used for germination can also support bacterial growth if contamination is present.
The NSW Food Authority advises that sprouts can carry bacteria including Salmonella, E. coli and Listeria, and that good hygiene cannot guarantee bacteria-free sprouts.
For safer home sprouting:
- Use clean equipment.
- Use drinking-quality water.
- Drain sprouts thoroughly after every rinse.
- Refrigerate harvested sprouts promptly.
- Discard any crop that develops slime, deterioration or an unpleasant smell.
Thorough cooking is the safer way to consume legume sprouts. People at greater risk from foodborne illness—including pregnant women, young children, some older people and people with weakened immune systems—should avoid raw or lightly cooked sprouts.
Frequently Asked Questions
How long should legume seeds be soaked?
Most larger legume seeds require approximately 8–12 hours of soaking. Current OzSprout guidance recommends 8–12 hours for chickpeas, peas and mung beans, while several lentil varieties are generally soaked for about 10–12 hours.
How often should legume sprouts be rinsed?
Rinse and thoroughly drain approximately two to three times each day.
Can I mix chickpeas, peas and lentils in the same jar?
You can combine them after harvest, but growing them separately is more reliable because their seed sizes, soaking requirements and harvest times differ.
How long do legume sprouts take to grow?
Most are ready in approximately two to six days depending on the crop, temperature and preferred sprout length.
Do legume sprouts need sunlight?
Strong sunlight is unnecessary. Keep the jar away from hot direct sun and focus on airflow, moisture and drainage.
Can I eat legume sprouts raw?
Raw sprouts carry a recognised food-safety risk. Thorough cooking is the safer option, particularly for people at increased risk of foodborne illness.
Legume Sprouts: The Bottom Line
Chickpeas, lentils, peas and mung beans can all produce substantial, crunchy sprouts, but they should not be treated as identical crops.
For the best results, grow each legume separately, use the correct seed quantity and soaking time, rinse regularly and drain thoroughly.
Once harvested, the different sprouts can be combined in salads, grain bowls, soups, stir-fries and other dishes according to your preferred flavours and textures.
