Storage times and freshness tips for thyme leaves 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.
Fresh in refrigerator1-2 weeks
Signs of Spoilage
Wilting, limp or drooping leaves, darkening or black spots on the leaves, slimy or mushy texture, development of mold (fuzzy white, green, or black patches), sour or unpleasant odor.
How to Check
Visual inspection: Look for bright green, firm leaves. Avoid any that are discolored, shriveled, or have visible mold. Touch test: Leaves should feel crisp, not slimy or overly soft. Smell test: Fresh thyme has a distinct, earthy, slightly minty, and aromatic scent. If it smells sour, musty, or 'off', it's best to discard.
Storage Tips
To maximize freshness, do not wash thyme until just before use. Wrap the unwashed sprigs in a slightly damp paper towel, then place them in a resealable plastic bag or an airtight container in the crisper drawer of your refrigerator. Alternatively, place the stems in a small glass of water (like a bouquet) and cover loosely with a plastic bag before refrigerating; change the water daily.
Frozen6-12 months
Signs of Spoilage
While generally safe if frozen properly, signs of diminished quality include significant freezer burn (dry, discolored spots), or a complete loss of aroma and flavor after thawing. Any signs of mold or spoilage before freezing mean it should not be frozen.
How to Check
Visual inspection: After thawing, the leaves may appear darker and softer, but should not be slimy or discolored beyond what's expected from freezing. Check for excessive freezer burn. Smell test: The aroma will be less potent than fresh, but should still be recognizable. An entirely absent or 'off' smell indicates poor quality.
Storage Tips
Wash and thoroughly dry thyme before freezing. You can freeze whole sprigs, or chop the leaves and freeze them in ice cube trays with a little water or olive oil. Another method is to spread chopped leaves on a baking sheet to freeze individually, then transfer to a freezer-safe bag or container. Label with the date. Frozen thyme is best used in cooked dishes as its texture will be softer upon thawing, making it less suitable for fresh garnishes.
