In dry storage, a blackened seasoning stays at its best for about six months. Keeping it in a cool, dry, dark place in an airtight container helps preserve the spices’ essential oils and aroma, so flavor remains strong for roughly 180 days. After that window, potency and freshness begin to fade, even though the mix is still safe to use. Shorter timeframes (like a few months) would understate how long the blend can stay flavorful, while a full year exceeds typical shelf-life expectations for a dry spice blend.
