Green beans are a convenient and nutritious addition to any pantry. But if you want to stock them up for a long time, you should know how long canned green beans are good for before they go bad.
We’ll explain how long canned green beans typically last and advise on how to store them best for optimal freshness.
How Long Can Canned Green Beans Last?
Canned green beans can last 2 to 5 years as long as they are stored properly. According to the USDA, most canned goods can last for several years so long as the can is still in good condition.
Typically, commercially canned green beans last longer than home-canned ones. Commercially canned green beans are usually marked with a “best before” or “best by” date instead of an expiration date.
The date on the label indicates that they are of their best quality for consumption. Consuming beyond that time doesn’t mean they are not safe; rather, they are not in the peak or best quality.
