How Long Do Mung Bean Sprouts Last?
Keep your sprouts crisp and safe for your next stir-fry or salad.
Mung bean sprouts last about 3–5 days in the refrigerator when kept dry.
Mung bean sprouts are a staple in many cuisines, prized for their crunchy texture and earthy flavor. Because they have high moisture content and a porous structure, they can become slimy or develop mold quickly if not stored correctly. To maximize their shelf-life, keep them in the refrigerator in an airtight container or a breathable bag, ensuring they stay as dry as possible. When they begin to lose their snap or show signs of moisture buildup, it is time to evaluate their safety for your next meal.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long do mung bean sprouts last in the refrigerator?
Mung bean sprouts last about 3–5 days in the refrigerator when kept dry. To maximize freshness, ensure they are not sitting in excess water.
Can I wash mung bean sprouts before storing them?
It is best to wash them right before use. Washing and then storing adds moisture to the surface, which accelerates spoilage and leads to sliminess.
Why do my sprouts get slimy so quickly?
Because of their porous surface and high moisture content, mung bean sprouts become a breeding ground for bacteria very quickly if they are not kept dry.
Can I freeze mung bean sprouts?
You can freeze them, but they will lose their characteristic crunch and become mushy upon thawing. They are best used fresh or frozen only if intended for cooked dishes.
Is it safe to eat raw mung bean sprouts?
While commonly eaten raw in salads, be aware that because sprouts grow in warm, humid conditions, they can harbor bacteria. Always wash thoroughly before use and cook if you have concerns about safety.
Keep those sprouts dry and chilly! If they start to slide off your spatula or smell funky, it's time to say goodbye.
