How Long Does Leeks Last?

Whole, untrimmed leeks stored in the fridge, wrapped loosely, last about 1-2 weeks, and yellowing at the green tops along with a slightly wilted, less rigid structure are usually the first signs of decline.

A slimy texture, particularly between the tightly layered leaves where dirt and moisture can collect, along with a strong onion-family smell well beyond a leek's normal mild scent, are the clearer signs of actual spoilage. Because leeks trap grit deep within their layers as they grow, a leek that looks fine on the outside can still have decay starting between inner layers, which is part of why thorough washing matters at the point of use, not just at the point of storage.

A leek's tightly wrapped layers naturally trap a small amount of moisture near the base, so trimming the root end slightly before storage, without removing so much that the layers loosen, helps reduce that trapped moisture and can modestly extend the leek's window compared to storing it completely untrimmed.

Leeks bought with roots still attached, rather than trimmed, tend to stay fresher slightly longer, since the roots continue drawing a small amount of moisture the same way they would if the plant were still growing, a subtle but real difference from a fully trimmed leek.

A leek stored with a few outer layers intentionally left dirty and unpeeled, removed just before use, keeps the inner layers better protected in the meantime.
