How long does pimento cheese last after opened?

It can actually last up to 3 weeks in the refrigerator if it is well-sealed as it should be. You may need to stir it when you pull it out but as long as it’s not spoiled, it’s good to use!

Does pimento cheese expire?

Once opened, as long as the product remains refrigerated, Palmetto Cheese should be good until the date printed on the side of the lid. However, like any product, the “freshness” will be compromised after a few weeks, though it would remain safe to eat. After the expiration date, the product should be discarded.
