Exactly How To Make Homemade Peanut Oil

What Is Peanut Oil?

A vegetable-based cooking oil, peanut oil is very popular because of its high smoke point. Edible peanut seeds are collected and used to make the oil, which is made up of around 50% monounsaturated fat, 32% polyunsaturated fat and 17% saturated fat. That means most of the fats in peanut oil are considered “healthy fats.”

There are several different types of peanut oil you can find, including cold-press peanut oil, gourmet peanut oil and refined peanut oil. Refined peanut oil is awesome for deep frying as it boasts a smoke point of around 450 degrees Fahrenheit. Depending on the kind of peanut oil you make or buy, there will be a bit of a nutty taste associated with it.

You’ll find that there are other benefits to peanut oil, not just being a great cooking tool. It is linked to a bevvy of health benefits, including alleviating constipation and helping with joint pain and heart disease.

And if you see groundnut oil or arachis oil, it’s the same thing as peanut oil.

  • 3 cup of Peanuts


  1. Prepare the peanuts: Once you've picked some peanuts up from the grocery store, start by de-shelling them. Next, remove the fine skin layer of each peanut. This will take some time and a bit of dexterity, but no worries, it's worth it in the end!
  2. Wash them: Afer you've done that, wash the peanuts in cold water, and then warm water.
  3. Let the peanuts soak: You've just finished washing them, and now it's time to let them soak in warm water, which will soften them up. This will take around 15 minutes.
  4. Make a peanut paste: After the peanuts have finished soaking, drain the water and place the peanuts into a blender. Blend the peanuts until they become a buttery-like smooth paste. If the blender is having a difficult time making the paste, you can add a few tablespoons of warm water, but be mindful you don't add too much water as that could change the consistency of your paste.
  5. Seal and refrigerate the peanut paste: After you've made the paste, place it into either a clean glass or plastic container and seal it well. Then, put the paste in the fridge where you'll leave it for around 24 hours. Make sure you don't touch or move the peanut paste while it's in the fridge, as that could disturb the process.
  6. Remove the oil from the container: After waiting the day, you'll see that the peanut oil has risen to the top of the paste. Take the container out of the fridge and use a strainer, which is one of the best ways for how to extract peanut oil at home.
  7. Use and store the peanut oil: You now have a peanut oil! You can use it right away or simply store it. And we'll cover storing your homemade peanut oil later in this blog.


To make more or less peanut oil, simply adjust the amount of peanuts. You need three times the amount of peanuts as oil you want to produce.

How To Make Peanut Oil At Home With A Peanut Oil Press

Another viable option for making peanut oil at home is to use a peanut oil press. There are two main types of oil presses, automatic and manual. Automatic ones will use a motor to press the peanuts, whereas manual ones will require you to do it yourself. Automatic presses are more expensive than manual ones.

To make peanut oil at home using a press, follow these steps:

  1. Follow the preparation steps above: De-shell, de-skin, wash and soak your peanuts. Then, allow your peanuts to fully dry.
  2. Pre-heat the press: For both automatic and manual presses, you’ll need to pre-heat the cage for around 10 minutes.
  3. Put peanuts in press: Once the peanuts have dried and the press has pre-heated, place the peanuts into the press’ cage.
  4. Use the press: You will then either flick the pressing switch on your automated press (button names vary depending on the machine) or start using the press’ crank, if its a manual one. Keep the pressing going until the peanuts have all gone through the machine.
  5. Store for 24 hours and then extract: Once you’ve finished, you’ll need to allow the substance to sit for 24 hours at room temperature. Keep it in the container and in a dark place. Once 24 hours are up, you can extract the peanut oil from the top and put it into a new, clean container.

How To Store Your DIY Peanut Oil

You’ve just made your very own peanut oil with or without a press, and you’re now wondering how to store it. Well, it’s quite simple. Once the oil is in either a clean glass or plastic container, you can decide between three options.

The most basic rules of storing peanut oil, like many other vegetable-based oils, are to ensure it’s sealed well and you keep it in a cool, dark area, away from any kind of heat source.

So, here are your three options:

Store It in a Pantry or Cupboard

Likely the most popular option for storing peanut oil is by putting it into a pantry or cupboard. They are typically cool and dark, and aren’t right by a heat source. Assuming you have other vegetable-based oils at your home, they are likely in a cupboard or pantry as well, so just store your peanut oil with them.

Put It In the Fridge

Another good way to store your freshly-made peanut oil is to keep it in the fridge. By doing so, you’ll extend its shelf life even more. It will thicken up in the fridget though, so remember when you go to use it, you’ll have to let it warm up to room temperature before it becomes runny again.

Freeze Your Peanut Oil

Lastly, you can always freeze your peanut oil. This method is recommended if you made a large batch of oil and you don’t plan on using all of it for a long time. A key thing to remember, however, is that if the peanut oil is frozen for too long, it could end up losing some of its nutty taste.

And if you make multiple peanut oil recipes, follow these guidelines for each and every one.
