How Long Does Vegetable Broth Last?

Vegetable broth follows the same 3-4 day opened fridge window as chicken and beef broth, since what actually governs a cooked broth's spoilage clock — moisture content, low acidity, and exposure to air once opened — has nothing to do with whether meat was involved in making it.

Because vegetable broth recipes and store brands vary more widely in ingredients and salt content than meat-based broths tend to, a very low-sodium or heavily vegetable-forward homemade batch could plausibly turn a touch faster than a well-salted commercial version — treating the 3-4 day window as a cautious default rather than a guaranteed minimum is the safer approach for a homemade batch specifically.

The same core spoilage signs apply here as for any broth — a sour or off smell and cloudiness beyond its normal light haze — though a vegetable broth's flavor and color can already vary more from batch to batch than a standardized commercial chicken broth's, making the smell test a more reliable check than appearance alone. A store-bought vegetable broth in a shelf-stable carton typically carries more sodium than a homemade batch, and that extra salt provides a mild additional protective effect once opened — not enough to meaningfully extend the standard 3-4 day window, but a small contributing factor in why a commercial carton sometimes seems to hold up marginally better than an unsalted homemade one.
