How to Freeze Peanut Butter

The great news is that peanut butter can be frozen for up to six months without deteriorating in flavour or texture. This makes it a great candidate for buying in bulk, as it can be expensive if you buy it in smaller portion sizes.

Assuming you’ve bought (or indeed made) a big batch of peanut butter, the following steps explain how to freeze it successfully. 

  1. Pick a Suitable Container
    While you can freeze peanut butter in a glass jar, plastic is always better. So, add the peanut butter that you wish to freeze to suitably sized Tupperware containers. Always leave an inch or so in space for expansion, so be careful not to overfill your containers. 
  2. Seal
    The biggest threat to the quality of your peanut butter is freezer burn. Therefore, you need to make sure your container is sealed tightly, particularly if you’re freezing your peanut butter for several months. Use a lid where possible, but tin foil or cling film are suitable alternatives. 
  3. Label and Freeze
    Make a note of today’s date, as well as the use-by date of your peanut butter, and place it in the freezer. Remember, you can freeze peanut butter for around six months. 

3 Tips for Freezing Peanut Butter

Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing peanut butter to have the best results:

Buy Tubs Instead of Glass Jars
If you know in advance that you’re going to freeze peanut butter, opt for those in tubs or plastic containers instead of glass jars. This means you don’t have to switch your peanut butter from one container to another, as plastic tubs are perfect for placing straight in the freezer. 

Use an Ice-Cube Tray for Smaller Servings
If you like the idea of freezing peanut butter in small serving sizes, consider freezing it initially in an ice cube tray before transferring it to a freezer-safe bag for long-term storage. This is ideal if you include peanut butter in smoothies or want easy access to small servings for other purposes. 

Freeze Any Nut Butter
Although we’ve focused here on peanut butter, you can essentially freeze any nut butter by following the same steps listed above.

How Long Can You Freeze Peanut Butter?

You can freeze peanut butter for around six months. As you can see from the above steps, freezing peanut butter is super straightforward and is a great way to preserve it in the long run.

However, as mentioned, freezer burn will cause your peanut butter to deteriorate in quality. As such, make sure it’s tightly wrapped, so it will retain its taste and texture until you’re ready to enjoy it. 

You Can Freeze Peanut Butter for up to 6 Months

How Do You Defrost Peanut Butter?

When you’re ready to enjoy your frozen peanut butter, it will be rock solid! So, to thaw it, take it out of the freezer and place it in the fridge overnight.

If you want to soften it further when you’re ready to enjoy it, pop it in the microwave for 5-10 seconds, so it’s easier to spread on your toast.

We wouldn’t recommend defrosting peanut butter in the microwave as you risk cooking it, which is not the best idea! 

Can You Refreeze Peanut Butter?

Providing you thawed your peanut butter in the fridge, there’s nothing wrong with freezing it more than once. You can also freeze peanut butter again as part of another recipe – your homemade peanut butter fudge brownies, for instance!

While it’s safe to refreeze peanut butter, we advise you to consider your portion sizes before freezing it in the first place, so you can easily remove whatever serving you need at any given time. 

Does Peanut Butter Freeze Well?

Peanut butter freezes extremely well. It’s for this reason that it’s such a popular spread to buy in bulk, as it’s nearly always cheaper to buy big tubs of peanut butter than it is to pick it up in individual serving jars.

So, if you’re looking to save yourself some money, don’t hesitate to pop your stores of peanut butter in the freezer.
