Here's How Long Peanut Butter Lasts After Opening

We wouldn't be surprised if you don't remember when, exactly, you acquired that jar of peanut butter sitting on your shelf. This ubiquitous nut spread is a pantry staple with vitamins, minerals, and protein all contained in a rich, creamy paste. Not only is peanut butter a powerhouse in terms of flavor and nutrition, but it also has a remarkable shelf life whether you are putting the best way to store all-natural peanut butter into practice or not. In fact, peanut butter has a shelf life of 2-3 months when stored in the pantry after it is opened. If stored in the refrigerator, however, an opened jar of peanut butter can last 6-9 months after opening.

It is every peanut butter fan's dream to get to the bottom of the jar before they have to let this delicious spread go, and there are many uses for an almost empty jar of peanut butter once they get there. Just be sure to read the label after opening to know how your particular jar should be kept.

There are other ways to know it is time to let a jar of peanut butter go besides keeping an eye on the calendar. If your peanut butter develops a metallic, bitter, or stale scent or a darker, dryer appearance, it is time to toss it. One key thing to remember is that if you are met with an oily substance at the top of your peanut butter there is no need to worry! It is common, especially with natural peanut butter, for oil to separate from the bulk of the paste. All you need to do is stir it back in and it is ready to be enjoyed. You can also store it upside down to help the oils stay mixed.

Getting creative with peanut butter creates more opportunities to finish a jar of peanut butter before it goes bad. While everyone knows of its iconic partnership with jelly, peanut butter is also delicious when paired with apples, granola bars, and so many other snacks. An easy way to use peanut butter to up your dessert game, too, is to toss it in as an underrated ingredient to boxed cake mix. With so many options, you'll likely use up the jar before it has a chance to go bad.
