How Long Does Leeks Last?
Storage times and freshness tips for leeks in different conditions.
Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.
Frozen (Blanched or Cooked)6-10 months
Signs of Spoilage
Extensive freezer burn (dry, discolored patches), strong off-odors upon thawing, or significant textural breakdown that makes them unpalatable (though some texture change is normal).
How to Check
Visually inspect for freezer burn, which looks like dry, grayish-brown spots. While frozen, they generally don't smell. Upon thawing, check for any strong, unpleasant odors. The texture will be softer after thawing, which is normal, but they shouldn't be completely mushy or disintegrated.
Storage Tips
For best quality, wash and slice leeks, then blanch them in boiling water for 2-3 minutes, immediately cool in an ice bath, drain very well, and pat dry before freezing. Alternatively, sauté them until tender and then cool completely before freezing. Store in freezer-safe bags or containers, removing as much air as possible to prevent freezer burn.
Raw in Fridge1-2 weeks (up to 3 weeks if very fresh and properly stored)
Signs of Spoilage
Yellowing or browning of the green tops, sliminess on the white bulb or cut ends, soft or mushy spots, strong unpleasant sulfurous or rotten odor.
How to Check
Visually inspect for discoloration, particularly on the green leaves and outer layers. Gently squeeze the white part to check for firmness; it should be firm, not soft or squishy. Smell the leek, especially near the cut end, for any sour or strong off-odors. A fresh leek has a mild, earthy onion scent.
Storage Tips
Do not wash leeks until just before use, as moisture can accelerate spoilage. Store them un-trimmed or lightly trimmed in a plastic bag or wrapped in a damp paper towel in the crisper drawer of your refrigerator. This helps maintain moisture and prevents wilting.
Cooked in Fridge3-4 days
Signs of Spoilage
Visible mold growth, sour or unpleasant smell, slimy texture, significant darkening or discoloration beyond what was present after cooking.
How to Check
Visually check for any fuzzy mold spots or unusual colors. Smell the cooked leeks for a sour or off-putting aroma. Touch the leeks to feel for an overly slimy or sticky texture. If in doubt, it's best to discard.
Storage Tips
Always store cooked leeks in an airtight container in the refrigerator within two hours of cooking to prevent bacterial growth. Ensure they cool down quickly before refrigerating.
