Reduced-fat peanut butter is a type of peanut butter that has had some of the fat content removed or reduced compared to regular peanut butter. Does this difference in fat content affect how you store reduced-fat peanut butter?
Well, yes and no. Storing reduced-fat peanut butter is similar to storing regular peanut butter. You can store it in the same way you store regular peanut butter, typically at room temperature or in the refrigerator if you prefer a firmer texture.
However, reduced-fat peanut butter may include other ingredients to compensate for the loss of fat, such as sugar, salt, or other stabilizers. This can make it more shelf-stable than its full-fat counterpart.
Let’s dive in and explore all the ins and outs of storing reduced-fat peanut butter!

How to store reduced-fat peanut butter
Reduced-fat peanut butter should be stored in a cool, dry location. This means you should avoid leaving it in direct sunlight or near heat sources, such as stovetops or ovens. Instead, find a spot in your pantry or kitchen cabinet that doesn’t get too warm.
Reduced-fat peanut butter (like Skippy, Jif) typically contains stabilizers and emulsifiers to prevent separation, so refrigeration is less important than it is with natural peanut butters. However, it can still help extend the shelf life of peanut butter and help maintain its consistency.
Always check the label on the product for any specific storage instructions provided by the manufacturer, as different brands may have slightly different formulations and recommendations.
Can you freeze reduced-fat peanut butter?
Freezing peanut butter? It might sound a bit unusual, but it’s a great way to extend its shelf life. If you’ve got an extra-large jar or you’ve found a great deal on your favorite brand, freezing is the way to go!
The freezing process
Freezing peanut butter is straightforward. Just follow these simple steps:
- Scoop out the amount of peanut butter you want to freeze and place it in an airtight container. Make sure there’s some room at the top for expansion. You can even portion it into smaller containers for convenience.
- Ensure the container is sealed tightly to prevent freezer burn and any odors from seeping in.
- Don’t forget to label the container with the date of freezing. Peanut butter can last a long time, and you’ll want to keep track of how old it is.
- Place the container in the freezer. It’s that simple!
Thawing it out
- When you’re ready to use your frozen peanut butter, simply move the container to the refrigerator and allow it to thaw slowly. This process can take several hours, so plan ahead.
- But here’s an important tip: avoid thawing it at room temperature. This can cause the peanut butter to separate and lose its creamy consistency.
How long does reduced-fat peanut butter last?
Most peanut butter (and other nut butter) products have a relatively long shelf life, but they don’t last forever.
The shelf life of peanut butter varies depending on different factors, including how it’s stored, the brand, and whether it’s opened or unopened.
Unopened reduced-fat peanut butter
When stored in ideal conditions (cool, dark, and away from moisture), unopened jars of reduced-fat peanut butter can last for a long time. In fact, many manufacturers label their peanut butter with a “best by” or “use by” date, which is typically about 12 months after production.
However, this doesn’t mean that the peanut butter magically goes bad after that date. It’s often safe to consume for several months beyond the indicated date, provided it’s been stored correctly. So, if you find an unopened jar hiding in the back of your pantry that’s a bit past its “best by” date, it’s worth giving it a taste test. Chances are it’s still perfectly good.
Opened reduced-fat peanut butter
Once you’ve cracked open a jar of reduced-fat peanut butter, it’s time to pay a little more attention to its shelf life. You can typically expect it to stay fresh for 2 to 3 months or more when kept at room temperature. In the fridge, open peanut butter can last 4 to 6 months.
Always check the “best by” or expiration date on the container and use the peanut butter before it expires.
How to know when reduced-fat peanut butter is rancid?
No one likes the idea of eating rancid peanut butter. Fortunately, there are some clear indicators that can help you determine whether your reduced-fat peanut butter has gone bad. Keep an eye (or nose) out for these warning signs:
- Give it a sniff. If your peanut butter smells odd, like spoiled or rancid oil, it’s time to toss it.
- Take a small taste. If it tastes strange, has a bitter or off-flavor, or seems generally unappetizing, it’s best to get rid of it.
- Check for any unusual changes in color, texture, or the presence of mold. Any of these signs should signal that your peanut butter is past its prime.
- While some oil separation is normal in peanut butter, excessive separation can indicate spoilage. If you see a significant layer of oil on top, it’s a good idea to discard it.
Remember, the smell and taste are usually the most reliable indicators. If it smells and tastes fine, chances are it’s still good to eat.
FAQs
You should store commercial, processed peanut butter in the pantry or on the counter as it does not require refrigeration and can become hard and less spreadable when chilled. However, natural peanut butter, which lacks preservatives, can be stored in the fridge to extend its shelf life and prevent oil separation, but it may become firmer in texture and harder to spread.
It is not necessary to refrigerate peanut butter once opened, but it can extend its shelf life and prevent oil separation. Personally, I like to refrigerate peanut butter after opening to preserve its quality.
To keep peanut butter fresh longer, store it in a cool, dry place, and make sure the container is tightly sealed to prevent air and moisture from getting in. For the longest possible shelf storage, I recommend refrigerating peanut butter.
No, Jif peanut butter does not need to be refrigerated. It can be stored at room temperature, which helps maintain its creamy texture for easy spreading.
