Canning Potatoes : Pressure Canning Potatoes for Food Storage

Updated: Jul 25, 2023


Have you ever wondered how to store potatoes long term? Potatoes hold for a long time in a root cellar or cool dark basement but for best long term storage I like to can my potatoes!


Canning Potatoes is very simple, it just takes some time. Potatoes are a low acid food therefore you must use a pressure canner, you cannot water bath potatoes they will not get hot enough in the center of the jar to kill off all the bacteria. New potatoes make the best for canning due to their thinner peelings and lower eye count.


You want to can smaller potatoes, or cut up larger potatoes into 1-2 inch chucks so that the potatoes in the center of the jar get hot enough to kill off bacteria.

It is not safe to can potatoes with the peeling on. Potatoes are grown in the ground with lots of dirt, removing the peeling decreases your chance of bacteria forming inside the jar once canned.

You're going to love how convenient having canned potatoes in your kitchen is. It is so nice having your potatoes already cooked when you get ready to make mashed potatoes, stewed potatoes, oven roasted potatoes, potatoes for your soups the list goes on and on.

 

Your List of Ingredients

  • Water

  • Salt

  • 10lbs Potatoes

Step 1: Let’s Get Started


Quart jars for canning
Clean Quart Jars

First thing we are going to do is wash all of our jars and get them ready for putting our potatoes in, then go ahead and get your canner on the stove with some water in it, and your pot of boiling water for your lids and rings, so everything is good and sterilized. Get you a pot of boiling water started ( or kettle) this is what we will be pouring into our jars. Lastly, get another pot of water on the stove to boil potatoes in.



Step 2:

Scrub and wash all of your potatoes. If you didn't already scrub all the peeling off go ahead and peel them too.

Be sure to get them really clean, as we do not want any dirt in our jars once we start to can.

Also cut out any eyes you might see, bug bites, and green spots, anything that might cause spoilage in our jars.

Step 3:

Cut the potatoes into 1-2 inch cubes and let them set in a bowl of cold water till you have enough for your first canner, this allows for some of the starch to come out and keeps the potatoes from becoming discolored.


Step 4:


Once you have enough for 7 quarts go ahead and get your first canner going, you can always wash, peel, and cut while your canner is processing.


Once you have enough potatoes cut up for 7 quarts you're going to boil them in a large pot for 5 minutes.

step 5:


Now you're ready to ladle them into your clean sterilized jars. Once you get your potatoes in, put one tsp of salt into each quart jar. Pour your boiling water in your jar leaving once inch headspace. Put your hot lid a ring on and place your jar in the canner.

Step 6:

Once all your jars are in your canner, follow the processing time for your elevation. While your first canner is processing be sure to go back to washing and cutting your potatoes up for your next canner.

step 7:

Once your canner is done and finished releasing all the pressure, your going to get your jars out with your jar lifter and place them on a towel to cool. If you run a lot of fans or your house is really cool you can place a towel over them, so they don't cool too fast and the jars crack.


Step 8:

Last, date your lids and store your canned potatoes in a cool dark place away from sunlight they should hold for a couple of years, the oldest we have ate is 4 years. I try not to can stuff we have a lot of already. Dont worry if your water turns cloudy that is normal potatoes are very starchy.


Enjoy


Enjoy having already cooked potatoes in your pantry. You're going to love how much prep time you save at meal time.
