How to Freeze Peanut Oil

As discussed above, you can freeze peanut oil despite freezing not being an ideal storage method, but if you must freeze peanut oil. Here is how to go about it.


The first step is to strain the oil. Straining separates the oil from the seeds, breading particles, and nut solids that may be present. If you don’t have a strainer, use a paper towel.

Once strained, transfer the oil to a container, preferably one that is light-resistant. Light resistant containers are better compared to glass containers since they are better suited for colder temperatures and will protect the oil from light as required. You can find light-resistant containers at any retail or home goods store.

While filling the container with oil, leave about ½ inch of space at the top to give room for expansion during freezing. Seal the container tightly, ensure the top is completely secured, then label it with the storage date to easily keep track of how long it has been in the freezer.

Place the container in your freezer. The peanut oil will be safe to use for up to one year.
