Can You Refrigerate and Freeze Peanut Butter?

Peanut butter is a popular spread in many countries. For those living in North America, it is a must-have item in the pantry, unless you are allergic to it.

Peanut butter is incredibly versatile and makes a perfect topping for savory and sweet foods. It is also shelf-stable, which makes it easy to store.

Despite the amazing long shelf life of peanuts and its butter, you may consider freezing peanut butter in a particular situation. Perhaps, you need to leave for a long holiday, and you just opened a jar of peanut butter.

Although peanut butter is rich in healthy nutrients, it is also high in calories. If you are trying to lose weight, it is better to limit your consumption.

Either way, you might be wondering about a proper way to prolong peanut butter’s shelf life. Is freezing it worth trying?

We got you covered. In this article, we walk you through the complete guide to freezing and defrosting peanut butter. So, read on!

So, Does Peanut Butter Freeze?

First thing first, peanut butter is a shelf-stable product that doesn’t really need refrigeration before and after opening.

Store-bought peanut butter typically lasts for one to two years. After opening, you can keep it in the pantry or cupboard.

It is not very hard to use up a jar of peanut butter in a couple of months or so. But, if you’re trying to limit this butter from your regular diet, you can keep it in the refrigerator to maintain freshness for another 3 to 4 months.

If you have a full, unopened jar of peanut butter, there’s no need to freeze it. Unopened jars usually last for at least 2 years. That being said, in most cases, you won’t need to freeze peanut butter.

Not all producers are in favor of freezing their products. For example, Skippy emphasizes keeping its products freezer-free. Cold temperatures harden the texture, which makes it less spreadable.

Store-bought peanut butter is often added with sugar, oil, salt, and miscellaneous ingredients. Pure peanut butter freezes better than those with more added ingredients.

In short, peanut butter doesn’t freeze equally well. So, you might want to try freezing a small amount and see how well it goes.

Freezing peanut butter is a no-brainer hack, and anyone can do it. Here is how you should do it.

1. Select the right container. It is okay to freeze peanut butter in its original plastic jar packaging, but not in a glass jar. If the amount is half full or less, consider transferring it to a freezer-bag or smaller container to save up space for other foods.

2. If you only use a small amount each time, consider packing in a smaller container or in ice cube trays. If you’re freezing in ice cube trays, flash freeze for several hours before packing them in a freezer bag.

3. Squeeze as much air as possible if you’re using a freezer bag.

4. Seal the container tightly.

5. Mark the container with the freezing date.

6. Place the package in the freezer.

Frozen foods should be kept at 0 °F (−18 °C) or lower for long-term storage. That’s why it is crucial to check your freezer’s temperature regularly.
