Expiration & Storage Tips
When does fresh thyme expire?
Fresh thyme, when unopened and kept in its original packaging, can last up to 14 days in the refrigerator. Once opened and exposed to air and moisture, fresh thyme needs to be used within a week for maximum freshness and flavor. However, it could still be safe to use, albeit less aromatic, for up to 2 weeks if stored properly. If you've bought loose thyme, aim to use it within a week. Fresh thyme can be frozen for up to 6 months, but be aware that its texture may change slightly upon defrosting, making it suitable mainly in cooked dishes.
How do you tell if fresh thyme is bad?
Thyme, like most fresh herbs, will show a few clear signs when it's past its best. First, look at the color: fresh thyme should be a vibrant green. If it's turning yellow or brown, or the leaves are wilting and appear slimy, it's time to toss it. Another strong indicator is the aroma — fresh thyme has a robust, earthy scent. If the aroma is weak or non-existent, or if it smells unpleasant, it's best not to use it.
Tips for storing fresh thyme to extend shelf life
• Store fresh thyme in the refrigerator — it's best kept in the crisper drawer which offers the ideal level of humidity.
• To extend the lifespan of your fresh thyme, wrap the stems in a slightly damp paper towel before placing in a zip-top bag.
• You can also place the thyme stems in a jar or glass of water, similar to a bouquet of flowers, and cover the tops with a loose plastic bag before refrigerating.
• If you choose to freeze thyme, wash it well and pat it dry. Lay the sprigs of thyme in a single layer on a baking sheet, freeze until solid, then transfer to a freezer-safe bag or container.
• When defrosting frozen thyme, do it gradually in the refrigerator or let it thaw in the dish as you're cooking it.
