What Is Peanut Oil?
Peanut oil is a vegetable-based oil that is popular among restaurants and households alike because of its high smoke point. If you’ve heard of or seen arachis oil or groundnut oil, they’re the same as peanut oil. It is made by taking the edible seeds of a peanut plant and using them.
You’ll find peanut oil in several forms, including gourmet peanut oil and cold-press peanut oil. However, the most popular cooking option is refined peanut oil, which is primarily used for high-temperature cooking, like deep frying.
Interestingly, peanut oil is linked to several health benefits, including aiding in constipation, joint pain and heart disease. It’s loaded with vitamin E, which is great for helping prevent skin issues like wrinkling and blemishes.

Can Peanut Oil Go Bad?
Peanut oil is a lot like other vegetable-based oils in terms of its shelf life. It can go bad, but how long it lasts depends on how well it’s stored, and whether the oil has been opened or not. For starters, you can hold onto unopened peanut oil for around one to two years, depending on the quality of the oil. And when it’s opened, the life of the oil will lower to roughly six months to a year.
Checking the “best before date” on the bottle is a great indicator to see how long the oil’s shelf life is, assuming that you purchased it instead of making it yourself.
How long can you store peanut oil is ultimately up to how well you store it. And we’ll cover that later in this blog.
Signs That Peanut Oil Has Gone Bad
There is one tried and true way to test if your peanut oil has gone bad, and that’s by smelling it. To do that, unscrew the lid and sniff the oil. If it has a rancid smell to it, you know it’s gone bad. Also, pay attention to the “best before date” on the bottle.
Of course, the best before date on any oil is typically not completely accurate as the life of the oil depends on how well you’ve stored it, and whether you’ve opened it or not. It’s also the date the manufacturer thinks it is best before, not the date it goes bad. But, it’s a good estimator.
You can do the eye test as well. If the oil becomes a deep-brown, that’s a major sign that it has expired and you need to throw it out.
Can You Reuse Peanut Oil?
Peanut oil is known as a fantastic oil to use for deep frying because its smoke point is around 450 degrees Fahrenheit. So that being said, it would be very inconvenient to have to change out the oil every time you wanted to deep fry something. And you won’t have to worry about that with peanut oil.
You can reuse peanut oil a few times before it starts absorbing the taste of the food that’s cooking in it. It could also start producing a rancid taste as well if it’s been used too many times.
On average, you should be okay using the same oil four times before replacing it.
Can You Freeze Peanut Oil?
Can you freeze point oil is maybe the biggest answer you want to know. And the short answer is yes, you can keep peanut oil in the freezer. However, it’s typically only recommended if you have the vegetable-based oil in bulk and you want to maximize its shelf life.
People have found that by storing peanut oil in the freezer for a long period of time, the oil’s taste changes a bit. Many kinds of peanut oil have a nutty taste to it, but that can be altered if it spends a lot of time in a freezer.
Also, it may be more inconvenient to use the peanut oil if you keep it frozen due to the amount of time it takes to defrost. You can set it out at room temperature and let it warm naturally. You can also place it in the microwave or on the stove to heat up as well.
So, keep these things in mind if you decide to toss the peanut oil into the freezer.
Can You Freeze Used Peanut Oil?
Whether peanut oil is used or unused, it can be frozen just the same. Just ensure you have the lid screwed on tightly and know the pros and cons of freezing, which we outlined in the section above.
How To Store Peanut Oil
For the question “how do you store used peanut oil,” you’ll be delighted to know that there are several ways to do it. First, always make sure you screw the cap on tightly to ensure it’s sealed. If you don’t, you’ll risk having the oil go bad quicker, or have its taste meld with another product or food that it’s near.
Then choose your option:
You’ll need to keep the oil in a cool, dark place, regardless of whether it is opened or not. So, a great place to do that is in the pantry along with your other cooking oils. Ensure that it’s in a cool area, away from any sort of heat source.
Another great place to store peanut oil, especially if you’ve opened it, is in the refrigerator. As mentioned, make sure the oil is sealed when placing it in there. By keeping it in the fridge, you’ll increase the peanut oil’s shelf life considerably.
As we mentioned, you can put peanut oil in the freezer as well. Although it’s the least recommended option out of the three, it’s still a viable alternative.
How To Store Used Peanut Oil
As we revealed to you earlier, you can reuse peanut oil multiple times. And storing it correctly is critical. To learn how to store peanut oil after frying, follow these steps:
Use a Strainer
It’s good practice to remove the oil from the deep fryer if you’re not planning on using it again for a bit. When you take it out, run the oil through a strainer to ensure there aren’t any extra food pieces in it.
Put It Into a Container
Next, pour the strained peanut oil into either a glass or freezer-safe plastic container, not the one it originally came in unless it’s now empty. Make sure the container is clean before you fill it with the oil, and it’s properly sealed.
In the section above, we listed three options for you to use as a storage space for peanut oil: a pantry, refrigerator and freezer. All of these options can be used to store used peanut oil.
How To Freeze Peanut Oil
When freezing peanut oil, you’ll need to follow certain steps to ensure you properly store it:
Seal It in a Container
If you purchased peanut oil from the grocery store, it’ll already be in a container, which will typically be plastic or glass. Make sure the container is freezer-safe.
And that goes for storing used peanut oil in the freezer as well. Once it’s in the container, ensure it’s fully sealed.
Place in Freezer
Next, place the container into the freezer in a way that there is no risk of it tipping over and possibly breaking, specifically if it’s glass.
You can also choose to freeze your peanut oil in ice cubes or other smaller containers. Once they are frozen, you can put the cubes into a freezer bag and seal it this way. This is a good way to go when you want access to small amounts of peanut oil at once.

How Long Does Peanut Oil Last?
Peanut oil’s shelf life largely depends on whether it’s been opened or not, as well as how it’s been stored. If you buy a bottle, bring it home and place it in a dark, cool area, it’ll last between one and two years, depending on the brand and kind you buy.
When you open it, you’ll cut its shelf life in half. It’ll be good for roughly six to 12 months. And remember, it’ll have a best before date that acts as an approximate guideline for how long it’ll last.
When the peanut oil is finally opened, it’s very important to keep it sealed after use and stored in either a pantry, fridge or freezer to extend its life as much as possible. Do not leave the peanut oil on the counter or near a heat source.
We hope that your questions about freezing and storing peanut oil has been answered by our blog. The most important takeaways are to keep the peanut oil sealed when you’re not using it to cook and store it in a cool, dark place.
Freezing is always an option, especially if you have a lot of peanut oil and you want to extend its life for as long as possible. It’s just much easier to keep it in the fridge or pantry.
