How Long Does Lemongrass Last in the Pantry?
How to Store and Identify Fresh Lemongrass
Lemongrass lasts about 1-2 weeks in the pantry.
To maximize freshness, keep lemongrass stalks cool, dry, and untrimmed until you are ready to cook. When storing in the pantry, your primary goal is to prevent moisture buildup and bruising, as dampness leads to limpness and mold growth. High-quality lemongrass should feel firm to the touch, emit a bright citrus aroma, and feature pale green or white layers at the base. As the stalks age, you will notice the outer leaves drying out first, followed by the core becoming woody and losing its fragrance. This guide tracks the progression from peak freshness through the stages of aging, helping you determine when to use it in recipes and when it is time to discard it.
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 can lemongrass be stored in the pantry?
Lemongrass lasts about 1-2 weeks in the pantry if kept whole, dry, and unbruised.
Can I store lemongrass in the refrigerator or freezer?
Yes. The refrigerator can extend its life slightly beyond two weeks, while freezing is an excellent option for long-term preservation. If freezing, chop the stalks first.
How do I know if my lemongrass has gone bad?
Check for mold, slimy patches on the stalk, a sour odor, or a texture that has become soft and collapsed.
Can I use dried-out lemongrass in cooking?
If the stalks are merely dry but still clean and firm, they can be used in simmered dishes like broths. If they show signs of mold or slime, discard them.
What are the best signs of fresh lemongrass?
Look for a strong, bright citrus scent and stalks that feel firm and crisp to the touch.
Prioritize firmness and scent. Keep your lemongrass dry, use it within 1-2 weeks in the pantry, and discard it at the first sign of mold or slime.
