Here's how to make your own natural homemade peanut butter from fresh or roasted peanuts.  There are many reasons to do so: taste, nutrition and safety.  Almost all of the commercial peanut butters contain added sugar, salt, oils, and often preservatives. Home-made peanut butter is not only healthier, is also tastes much better!  You can make it smooth, chunky or in between!  You can use peanuts, cashews, pecans, hazelnuts, almonds, pistachios, or other nuts, including a mixture.

You won't need to worry about your homemade peanut butter being contaminated with Salmonella nor cancer-causing alfatoxins (see this page for more information about aflatoxins). If you need a reminder that you shouldn't trust your health to corporate processed foods, just read about the many recalls of contaminated peanut butter:

  • 2012, October: Sunland, Also see this page for the US Government page about the peanut butter recall (A total of 35 persons infected with the outbreak strain of Salmonella Bredeney have been reported from 19 states. Eight ill persons have been hospitalized, and no deaths have been reported. 63% percent of ill persons are children under the age of 10 years.)
  • January 2009 outbreak of illnesses caused by Salmonella Typhimurium from peanut butter and peanut paste produced by the Peanut Corporation of America (PCA) at its Blakely, Georgia processing plant.
  • 2007 recall of Peter Pan peanut butter

So let's see how easy it is to make your own peanut butter! Here's how to do it, complete instructions in easy steps and completely illustrated.

Prepared this way, the jars have a refrigerator shelf life of 3 or 4 months  and indefinitely in the freezer. Unfortunately, it is not considered to be safe to "can" peanut and other nut butters at home.

Directions for Making Peanut Butter

Makes about 1 quart of peanut butter


  • 1 bag of unshelled peanuts  or 1 can (2 cups or 1 lb) of shelled, raw or roasted peanuts (I think unsalted is healthier - you can always add salt, if you want to)
  • Vegetable oil (just a small amount, 1 or 2 tablespoons).  I prefer peanut oil, but corn, sunflower, safflower, etc,. all work.  I would not use olive oil because it would adversely affect the taste.


  • Blender or Food processor (a blender or fine food grinder seems to work best)

  • Bowl

  • Spatula

Recipe and Directions

Step 1 - Shell the peanuts

Unless you bought shelled peanuts, you will obviously need to shell them and discard the shells (they make great mulch in the garden or add to your compost).  I just quickly shell them by hand, and don't bother much with the thin read skins.  When I have the peanuts shelled, I take them outside and just blow into the bowl while stirring it.  The skins float away!

Step 2 - Assemble your blender or food processor and ingredients

Set up your blender or food processor with the metal food processor blade attached, and add 2 cups of raw or roasted shelled peanuts into it.

Step 3 - Get chopping!

Cover the bowl with the blender's lid and chop up the peanuts continuously for 2 to 3 minutes or until the mixture starts to clump up and is finely chopped.

Step 4 - Scrape and finish chopping

Scrape down the food processor bowl to mix back the peanuts that are pushed to the outside where they won't get chopped.  Process until you get the consistency you like (chunky or smooth).

Step 5 - Add the vegetable oil

Most peanuts don't contain enough oil naturally to make a smooth butter. You only need to add about 1 and 1/2 teaspoons of vegetable oil (peanut oil is best, obviously, but any neutral flavored oil, like sunflower or canola oil works). Just mix it in with a fork.  Your blender may not be powerful enough to do this without sticking, so you may want to mix the oil in, in a separate bowl.

Step 6 - Tasting

Taste the peanut butter and add a touch of salt, if you like! For those that prefer a sweet peanut butter, you can add 1 tablespoon of  honey, brown sugar or, if you are diabetic, Stevia (in a prepared form like Truvia, it measures same as sugar; if you use another form, you will need do your own conversion) - or Splenda, if you prefer, or other artificial sweetener.



Step 7 - Eat or store

Just spoon peanut butter into a jar and seal. Store it in the refrigerator until you use it.  It should keep for a month or two. You can also freeze it.  It will keep indefinitely in the freezer. In both cases, you may need to stir the peanut butter to mix the oils back in (the oil tends to separate over time). And no, you cannot "can" the peanut butter - it is too low acid to safely can with home equipment.
