Groundnut oil can’t be called a common product compared to other oils, however, this natural foodstuff has found its place in many kitchens due to its nutty flavor and usefulness.
Since it is quite rare, people often wonder how to store peanut oil correctly.
Let’s see what we can discover about this!
How Long Does Peanut Oil Last?
Like any other natural vegetable or nut oil, groundnut product is rather durable. Of course, when buying a flask of it in a store, we can find the best-by date indicated on the tag but it only shows until when the oil will keep its optimal potency.
For sure, this date doesn’t show that the product will become spoiled right after the expiry date.
Nevertheless, it doesn’t prove that peanut oil can last forever either.
Like any organic product, it has its final term of use. However, if we follow the basic storage requirements, it will be possible to prolong its lifespan to its most. In this case, it will be possible to stock groundnut oil for months and sometimes even for one or two years after its expiry date!

But before we discover what actions to take to reach that goal, let’s see how long we can safely stock this product at home if we do everything right.

Remember though that this information may slightly vary since the duration of storage hangs significantly upon the quality of the product and better oils last longer than their cheaper counterparts.
Storage Tips And Nuances
So how do we store peanut oil?
In fact, it’s not a big deal.
- Keep the bottle tightly screwed all the time to prevent contamination
- Stock it in a shaded and dry place
- Keep the bottle away from heating objects
- Refrigeration is not a must even for an unscrewed bottle but if the plan is to stock it for a year or so, you’d better chill the foodstuff
- In case some utilized product must be saved, never let it stay in the deep fryer. Drain it to the plastic/glass tank after it is not hot anymore and double-check there are no food particles in it.
Such rules seem simple but believe us, they can literally save the product and preserve it fresh and safe for you longer.
How Long Does Peanut Oil Stay Good For Deep Frying?
Some of us often exploit groundnut oil for deep frying since it gives the food its nutty aroma. Naturally, everyone is curious about how long such a product will remain suitable for this purpose.
Well, we can say that it hangs upon whether your product is opened or still sealed.
Since unscrewed oil stays fine for twelve months for sure, it would be more reasonable to go for this one for deep frying.
On the other hand, if you already unscrewed the bottle, it’s ok to exploit it if the product is still fine and usable.
In case you notice any symptoms of rancidity, don’t deep fry on this oil since it can be harmful!
How To Tell If Peanut Oil Is Bad?
And here we have come to the most worrying issue.
How to define whether peanut oil is bad or good?
Go for one of these 100% working methods to do this:
- The bad oil becomes deep-brown, its shade darkens
- Its odor became unpleasant and rancid
- If the oil is cloudy or you see the fats breaking down throw it away without hesitation!
Such a product is unsuitable for both frying and using it as it is.
4 Tips To Tell If Peanut Oil Has Gone Bad
The better you look after your foods, the more chances they will last longer, remaining safe to consume and keeping all their vitamins and nutritious elements.
But this rule does not only work for fruits, vegetables, and other products. It’s also true for oils, including peanut oil. Below, you can check four signs that will show you your oil has turned bad or is getting close to this point.
Your Peanut Oil Looks Different
When peanut oil becomes bad, it changes its color. This is one of the first symptoms of deterioration and spoilage. If you check a bottle of oil and see it has turned brown or its shade has darkened, this is the first red flag for you!
You should check whether other spoilage symptoms are present (read about them below) to decide what to do.
Your Peanut Oil Smells Strange Or Unpleasant
Smell is another common sign of a product’s decay. We all know that bad/spoiled foods start smelling off and unpleasant. With peanut oil, it’s the same. If you have any suspicions that your peanut oil might turn bad, open the bottle and give it a good whiff. If your oil gives off a putrid or chemical-like smell, it’s most likely rancid already.
Your Peanut Oil Tastes Bad
Taste is another obvious sign of food spoilage that can show you clearly your product is not edible anymore. Speaking of peanut oil, sooner or later, it goes rancid anyway, even if you keep it unopened in a cool spot. If you are not sure whether it is still consumable, try to taste it. You can easily tell that your oil has gone rancid if it tastes sharp or bitter.
Your Peanut Oil Has Lost Its Cooking Quality
This “symptom” is rarely considered by people, but you should keep it in mind as well to tell whether your peanut oil is ok or not. Perhaps, it’s a bit harder to notice, but once peanut oil becomes rancid, it loses its ability to be used in food preparation. So if you try to use it for frying, for example, and you see it doesn’t work, then it’s definitely rancid.
The Risk of Eating Expired Peanut Oil
Everyone knows that eating spoiled/rotten/bad foods often leads to food poisoning or at least it can make you pretty sick. This is why people often wonder whether using rancid or suspiciously smelling/tasting peanut oil can be dangerous.
First of all, if you sense or taste that your peanut oil is not good anymore, you should discard it immediately. If you use old or expired peanut oil for cooking, it will give your dishes an unpleasant rancid taste.
However, it will not cause you much harm or make you sick! Anyway, if you are in doubt about a bottle of peanut oil that has been on the shelf for a while, just throw it out to be safe.
Can You Freeze Peanut Oil?
Freezing foods is the best and the simplest way of preserving them and keeping them edible longer. However, when it comes to oils, it’s often not quite clear whether they can be safely frozen and, if they can, then how to do it correctly without spoiling the product.
Speaking of peanut oil, it does freeze well. However, if you decide to freeze it, note that it’s likely to lose its flavor, especially after long-term freezing (for a year or more). On the other hand, its frying and cooking abilities will not degrade and it won’t affect the taste and flavor of the dish.
You can freeze peanut oil by pouring it into a container. Just ensure you fill it in at most four-fifths of the total volume. Then, seal the container, and transfer it to the freezer.
But some people freeze peanut oil in ice cube trays since it makes it easier to add it to dishes later. You just need to trow a few cubes onto your frying pan without pre-thawing them!
Can You Reuse Peanut Oil After Frying?
Some people wonder whether it is safe to reuse peanut oil after frying.
In fact, it is possible but only if following certain instructions to make it safe to make use of later.
- After cooking, leave the product to chill
- Remove all the bulky particles of batter
- Take an empty tank, settle down a cheesecloth over it, and strain the product
- If noticing any debris, throw it away
- Close the tank firmly and stock it in a cool and dry place
And remember the oil breaks down with every next use so you’d better never cook in it for more than two times.
Groundnut oil is a great and 100% organic product of nature that serves as the perfect replacement for the less useful and healthy foodstuff that we are used to. It fits fryings, hot savory dishes, and salads giving them a slightly nutty aroma.
Stock it correctly, and this product will serve you very long.

Hey everyone! I have an issue with my peanut oil. I fried on it to make french fries and I have pretty much left. Do you have to refrigerate peanut oil after use? Does anyone know? Thanks.
Hello. Yes, chilling is a must, otherwise, the product will spoil pretty soon.
How long does open peanut oil last? Where is it better to stock it in this case?
An opened bottle of oil is best to be stocked ina pantry tightly closed and away from the bright light and heat.
Good afternoon! Is there anyone here who knows about peanut oil? I need a hint. How can you tell if peanut oil has gone bad? I recently noticed some cloudiness in mine. Is it bad?
Hey! I’m afraid yes, your oil has turned bad. If it changes color or becomes cloudy, it’s the sign of spoilage 100%.
How expensive is peanut oil? Does a high price mean it is more qualitative?
Hello! Well, normally the price is between 22 to 25 dollars as far as I remember. At least, mine always costs like that. But I know it’s possible to find more expensive bottles. Don’t know about the quality but I heard that the expensive oils are indeed better.
Hey! Please give me a hand guys! What can you do with old peanut oil? It’s not reused, it’s just a bit rancid. Thanks!
Hey there!
My guess is that you just have to dispose of it. Screw the bottle firmly and throw it to the trash.
And I’d not recommend cooking on it, of course!
How long can you reuse peanut oil for frying? Are two-three times ok? Please, give me any ideas! Thanks.
Hello.
I know for sure that 3-4 times is the optimal number of times it can be reused. After that, the oil may (and it most likely will) become harmful.
Does anyone know how to store peanut oil after deep frying? I have pretty much of it left and I’d like to save it for the next time. How to make it not go rancid?
I’d recommend you keep it tightly sealed and refrigerated. It always works, but of course, it doesn’t mean you can store it for months like this! The faster you make use of it, the better since oil tends to spoil anyway, especially if it was already used.
I’d like to know how to store and reuse peanut oil for frying. Does anyone have approved recommendations for that? I’m asking because I could not find anything clear on the internet, and none of my friends use this oil for cooking!
Hi! Yes, peanut oil can be reused. As for the storage, feel free to keep it the same way you would store any other vegetable oil, for instance, sunflower oil. Just keep it tightly closed in your pantry.
As for reusing it, it can be reused two or three times, but after that, it will become unsafe to consume! So while it is still usable, filter it after the first use. I use a fine strainer and a fine cheesecloth for this. And then simply cover it tightly and refrigerate!
Is it allowed to store peanut oil in the refrigerator? Will it not get rancid? I have never used this type of oil before so I’m not familiar with its storage nuances. Ill be happy if somebody could give me a hint!
Normally, this oil is stored in a pantry. Just like any other vegetable oil. But if it’s getting closer to its expiration date, then, of course, you can transfer the bottle into the fridge. Only be ready that it will turn cloudy and solidify!
I tried to substitute sunflower oil for peanut oil recently, but I don’t know how to store it properly. Should peanut oil be refrigerated after opening?
Well, usually it should not be chilled. You don’t refrigerate your linseed oil, do you? So it’s the same with this one. Besides, if you put it into the fridge, it will most likely solidify and will surely get cloudy. So better keep it in a pantry or in a kitchen cabinet away from heat, moisture, and light.
Can somebody tell me how to reuse peanut oil and whether it is possible at all? I heard it can be used for deep frying, but is it ok if I save it afterward?
It’s totally fine if you save it after deep frying. Moreover, peanut oil can be used up to four times for this way of cooking! To reuse it later, you need to let it cool down after the first use. Then, filter the oil using a fine cheesecloth and a strainer, seal tightly in a container, and refrigerate.
Are there any tips on how to store extra peanut oil so that it lasts longer? I have two extra bottles that are not opened, but I will definitely not use them soon enough! It would be a pity if I had to throw it away because it was spoiled. Maybe, there is a way to save it somehow?
Since it is not opened, I’d say you could store it in your pantry or at least in your kitchen cabinet. Only then, make sure that your oil is away from heat, moisture, and light, otherwise, it will get rancid!
There is another option you can opt for, and it’s your fridge. If you store the oil in it, you will significantly prolong its lifespan. However, it may turn cloudy because of the cold!
Hi! Could you please recommend the best peanut oil storage containers? The container the oil was initially in has cracked, so I have to find another one. I thought o plastic. Will it be ok?
Hello. We recommend you use a glass jar to store peanut oil. Glass jars are air-tight, besides, they can be reused many times. As an option (and if you’re afraid to break the jar by accident), you can use a metal jar instead.
How many times can you reuse peanut oil? If I use it for cooking, and there’s some oil left on the frying pan, can I use that leftover oil later?
I’m not sure any oil can be reused like that. I remember that once you cook with any oil, that oil should not be reused since it can be harmful for your health. I don’t know though, maybe, peanut oil is different.
Hello. Could you please explain how to store used peanut oil for reuse?
Hello. If you have glass air-tight jars, those would be the best storage containers for your oil. As an alternative container type, opt for metal jars. ALso, store your oil in the fridge to ensure it lasts longer. It might thicken, but it’s absolutely normal.
I bought fresh peanut oil last month and now there’s still pretty much of it left. But I sniffed it today and it seemed to me it smells not quite good. How to tell if peanut oil has gone bad?
Taste it. You can tell that your oil has gone rancid if it tastes sharp or bitter. The smell may also change, making your oil to give off a putrid or chemical-like odor. But its taste is the most obvious sign since it changes significantly when the oil gets bad!
What does rancid peanut oil smell like?
Rancid peanut oil will have an unpleasant odor that reminds you of chemicals. Also, the odor might sense putrid.
Can you freeze peanut oil to make it last longer? I remember I read somewhere that some oils can be frozen to extend their shelf life. Can I do that with peanut oil?
Yes, freezing peanut oil is possible! I do it all the time! In fact, freeizng extends the oil’s shelf life, making it possible to store the oil for at least a year extra if it hasn’t been used before. If you want to freeze used peanut oil, it can be frozen for up to six weeks before being discarded. However, note that freezing might alter the oil’s aroma and flavor!
Hi! I need your advice, folks. Can old peanut oil make you sick? Mine was stored correctly, and it smells/tastes ok, but I’m still worried!
