How Long Does Dried Thyme Last?
Shelf Life and Storage Tips
Dried thyme is a popular herb known for its aromatic and savory qualities that enhance a wide array of culinary dishes. Its longevity is one of the reasons it's favored by both home cooks and professional chefs. When stored properly in an airtight container, away from light, heat, and moisture, dried thyme can retain its potency for up to three years. The key factors ensuring its extended shelf life include a cool, dry, and dark storage environment.
Conversely, fresh thyme's shelf life is considerably shorter, generally lasting between 7 and 14 days when refrigerated. The delicate nature of fresh herbs means they are more susceptible to spoilage and typically need to be used soon after purchase.
