How to Tell If Fresh Rosemary Has Gone Bad
How to Identify Fresh Rosemary Spoilage
Fresh rosemary lasts 7-10 days in the refrigerator; after this period, look for limp leaves, dark discoloration, or a slimy texture.
Maintaining the aromatic potency of fresh rosemary requires proper refrigeration. When stored correctly, these woody sprigs typically remain viable for 7 to 10 days. To ensure quality, monitor the appearance and scent of your herbs closely. Healthy rosemary should feel firm and smell sharply of pine. As it ages, you may notice the needles becoming dull or drooping. If you encounter black spots, a slimy coating, or a sour odor, the herb has spoiled and is no longer suitable for cooking. This guide provides a timeline to help you distinguish between a slightly wilted herb that can still be used and one that must be discarded.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does fresh rosemary stay fresh in the refrigerator?
Fresh rosemary typically lasts 7-10 days when kept in the refrigerator. Beyond this window, it usually loses its texture and color.
