Mung bean sprouts are crisp, juicy, and a classic ingredient in Asian cooking, from stir-fries to soups. They are also one of the easiest sprouts to grow at home. With just a jar and fresh water, you’ll have delicious sprouts ready in only a few days.

Supplies

  • Broccoli sprouting seeds
  • Sprouter: A sprouter can be bought from retailers or online stores. You can even make your own. Many sprouters tend to have a screen lid so the draining process is easier and more efficient.

NOTE: Make sure you’re washing your sprouter and bowl(s) in between crops.

Sprouting Instructions

  1. Add 5 tablespoons of mung beans to your sprouter or jar. Fill with three times as much cool water, stir, and soak for 8–12 hours until most beans are pale. If more than 20% remain dark, drain, refill with fresh water, and soak a few more hours.
  2. Drain and rinse thoroughly. Keep beans at room temperature, out of direct sunlight, and do not soak again.
  3. Rinse and drain every 8–12 hours until beans have short roots. This usually takes about 2–3 days, depending on your room temperature.
  4. Rinse one last time. Spread beans on a clean towel and pat dry. Transfer to a resealable bag or container and refrigerate for up to 5 days.

Sunlight & Temperature

  • Indirect light: Keep sprouts out of direct sun to avoid bitterness.

  • Cool conditions: Around 70°F (21°C) is ideal. In warmer or humid conditions, rinse every 8 hours.

  • Crisp texture: Slightly cooler temperatures help produce firmer, juicier sprouts.

Troubleshooting Common Problems with Sprouts

  • Beans still dark after soaking: Drain, add fresh water, and soak a few more hours.

  • Sprouts taste musty: Usually caused by poor drainage. Rinse thoroughly and tilt your jar at an angle for airflow.

  • Sprouts are soft or weak: Often from overcrowding. Use fewer beans per jar for best results.

Storage and Use 

  • Always rinse sprouts before eating.

  • Store in a sealed container in the refrigerator for up to 5 days.

  • Use fresh in salads, wraps, or sandwiches, or add a crunchy, nutritious boost to soups and stir-fries.
