Imagine a life where you can crack open a jar of home-canned potatoes and suddenly, 50% of your dinner is prepped and ready to go. Stop dreaming. That time is now.
Do Potatoes Have to be Pressure Canned?
Yes, they do. I have to reinforce this point: you cannot safely can potatoes in a water bath canner.
Potatoes, like all low-acid vegetables, must be preserved using a pressure canner.
Once you master your pressure canner, use it for things like Canning Chicken Broth, Canning Beets, Canning Peas, Canning Green Beans, Canning Corn, Canning Pumpkin, and Canning Carrots. This is the pressure canner I have had for a decade and I love it.
If you don’t have a pressure canner, check out my tutorials on dehydrating potatoes and how to freeze potatoes.
What Potatoes Are Best For Canning?
You’ll want potatoes that are waxy and great for boiling. In most cases, red potatoes work best. Russets and Yukon golds are better left for baked potatoes, Instant Pot Potato Salad, or making mashed potatoes (like Boursin Mashed Potatoes, Wasabi Mashed Potatoes, Instant Pot Mashed Potatoes, and Fluffy Mashed Potatoes).
Can Potatoes be Canned Raw?
No. Potatoes must be pre-cooked before they’re placed into jars and canned. Unlike when canning peaches or canning pears, you can’t raw pack potatoes. See the recipe card at the bottom of the post for cooking times and details.
Do You Have to Peel Potatoes Before Canning?
Yes. I know, bummer because it is extra work. But the canning Jedis over at the National Center for Home Food Preservation stress that the potatoes must be peeled. And so, I peel!
Root crops can harbor soil-borne microbes and peeling is an extra insurance policy to keep your food safe.
CANNING SUPPLIES FOR Canning Potatoes
Check out this in-depth post for a complete list of canning supplies.
You’ll need:
- Potatoes
- Pressure Canner
- Large saucepan (I use my enameled dutch oven)
- Canning funnel
- Pint or quart canning jars (thrift stores are my favorite sources for these!)
- New canning lids and clean rings
- Jar lifter
- Ball Blue Book of Home Preserving
- Cutting board
- Sharp knife
- Vegetable peeler (this one is my favorite – I actually have two!)
- Comfy shoes
How to Use Canned Potatoes
Quickly cook some organic grass-fed beef and stock in the Instant Pot (ala Whole30 Beef Stew) and add in a jar of canned potatoes and a jar of canned carrots when it is done cooking.
You can also use them in Instant Pot Potato Soup, throw some in these Green Beans and Tomato Sauce to make Fasolakia, or even Instant Pot Lentil Soup.
HOW MANY PotatoeS DO YOU NEED FOR CANNING?
Overall you’ll need about 2.5 pounds (peeled) per quart jar.
For seven quarts, you’ll need about 20 pounds. For nine pints, you’ll need 13 pounds. A US bushel is 50 pounds and will net you 18-22 quarts.
HOW TO CAN Potatoes
*I’ll walk you through it here with photos, and a detailed and printable recipe card is available at the bottom of this post.
Wash and clean your jars. It is no longer necessary to sterilize jars before canning (hurray!) but you should make sure they are preheated enough to not crack when placed in hot water.
You can put them in a clean dishwasher and run them through a quick wash cycle, or place them in a large pan with some water in a low-heat oven (my lowest temp is 170 degrees) until you need them. I’ve even just put hot tap water in them before and left them on the counter.
Wash your lids with hot soapy water. Rinse and place them in a clean bowl for now.
Rinse and scrub your potatoes. Peel, and rinse again.
For canning diced potatoes – cut peeled spuds into 1/2 inch cubes and rinse. Cook in boiling water for 2 minutes and drain.
For canning whole (baby) potatoes – choose spuds that are 1-2 inches in diameter. Cook peeled potatoes in boiling water for 10 minutes and drain.
Add 3 quarts of water to your pressure canner and put it on a burner set to high. Make sure there is a canning rack in the bottom of the canner.
Add the potatoes to the jars. Pro tip: wiggle the jar often as you add them to allow them to settle and make room for more.
Using a canning funnel, carefully and slowly add clean boiling water (do not use the same water you used to cook the potatoes), leaving 1-inch of headspace. Headspace is the distance between the top of the food and the top of the jar.
Using a long utensil (I prefer a plastic chopstick), remove all the air bubbles from the jar.
Clean the rim of the jar very well with a hot damp rag. Any food debris left on the rim may impact the seal of the lid in the canner.
Place a clean lid on the jar. Add a ring, and tighten to fingertip tight.
Using canning tongs, gently place the jars in the canner. Lock the lid. Soon, steam will start coming through the vent pipe (I call it the steam chimney). Allow the steam to pass through for about 10 minutes. Then put the pressure regulator (I call it the chimney cap) on top.
Pretty soon, the air vent will pop up. That is a sign that you’re starting to build pressure inside the canner (get excited. This is happening!).
Under normal conditions, potatoes need to be pressure canned at 11 pounds of pressure for 35 minutes for pints and 40 minutes for quarts. See the chart below for any changes to processing times.
When the dial gauge reaches 11 pounds of pressure, reduce the burner temp to medium, and start your timer. The pressure must stay at 11 or (a little bit) above for the duration of the cooking time. You’ll likely need to adjust the temp on the burner a few times depending on your stove.
When the time is up, remove the canner from the burner and allow it to sit until you hear a distinctive “click” of the air vent dropping. Remove the pressure regulator and carefully remove the lid (Pro tip: I always use oven mitts when I take the lid off because the steam is super hot).
Let the jars sit for 5 minutes in the canner and then lift them out with canning tongs. Pro tip: allowing the jars to sit in the canner with the lid off can help reduce the siphoning of liquid in your jars. Siphoning is when liquid seeps out from under the lids and reduces the overall amount of liquid in the jar.
If just a bit of siphoning has happened and your jars are sealed, your item is still safe to eat but use your best judgment. I tend to quickly use any jar that has experienced siphoning simply because it can discolor the food at the top not covered in the liquid.
Place hot jars on a towel where they can sit undisturbed for 12 hours.
After a few hours, to check for sealing, gently press down in the middle of the lid. If the lid has no give, it’s sealed. If you can press the lid in and it pops a bit, your jars are not sealed.
HOW LONG DO CANNED Potatoes LAST?
If stored in a dark cool place, they will last for 12 months. If you open a jar for use and don’t use it all, you can store it in the fridge for up to three days.
Pro Tips/Recipes Notes
- As you prep your potatoes, add them to a large bowl of ice water to keep them from browning until canned. You can also use a bit of ascorbic acid in the water, but I don’t find that it has been necessary.
- You can add salt to each jar prior to canning it. Use pickling salt and add 1/2 tsp per pint or 1 tsp per quart. Personally, I find the unsalted version easier to use in recipes because it allows me to control the overall sodium.
- Pressure canners can often leave white lines on lids and rings. It’s totally normal and safe. To prevent this, add 1/3 cup of white vinegar to the canner with the 3 quarts of water before processing.
- If you don’t have enough jars to fill the canner, consider Canning Water in a few jars to stock your emergency drinking water supplies.

If I were to water boil for sealing–instead of the pressure cooker
How long on a steady boil do I need to boil the potatoes for
Not a big fan on using pressure cooker
Thank you
You cannot safely water bath can potatoes. You must use a pressure canner.
Can u can russet potatoes?
You can, but they’re not ideal. I’ll copy and paste the info from the post addressing this:
WHAT POTATOES ARE BEST FOR CANNING?
You’ll want potatoes that are waxy and great for boiling. In most cases, red potatoes work best. Russets and Yukon golds are better left for baked potatoes, Instant Pot Potato Salad, or making mashed potatoes (like Boursin Mashed Potatoes, Wasabi Mashed Potatoes, Instant Pot Mashed Potatoes, and Fluffy Mashed Potatoes).
Why do you have to parboil the potatoes when it’s only potatoes but not when in beef stew? Second can we add chicken stock or broth to potatoes in stead of water?
Hi Aileen, I have never canned beef stew before, so I’m honestly not sure. I’m assuming because beef stew would be fully cooked before being canned.
And yes, you can add stock instead of water. Chicken stock only needs to be canned at 11 lbs of pressure for 25 minutes, so it would process even longer with the potatoes, therefore making it safe.
I have tried canning potatoes several times using red potatoes, but the liquid is always so cloudy. I realize this is the starch but yours look so clear and delicious. I am picky about how my canned goods look, and I am wondering if you have any idea why this happens to me. I am a very experience canner. I usually can between 500 nd 600 quarts per year. BTW National Center for Home food Preservation is my canning bible. Thank you.
I LOVE NCHFP!! They are definitely my go-to whenever people have questions about elevation processing adjustment.
Do you follow the steps of rinsing and switching out the water for clean water every step of the way? That seems to get rid of most of the starch for me.
In “The All New Ball Book of Canning and Preserving”, there are several recipes canning uncooked potatoes with seasoning and hot broth. That would not be that different from using water and salt. I peel mine and leave them soaking in cool water until it is time to fill the jars. It works very well and the potatoes taste great. I pressure can them per the approved time and pressure guidelines and size of jars used.
Do you have a publish date for that book so I can look into it?
I had a New Ball Book of Canning that was well over 20 years old. For safety purposes, I only educate my readers on processes that are 1-3 years old to make sure I’m giving them the most current safe practices.
Hi
Could I can sliced potatoes? Peeled and everything.
Thanks!
Melody
Melody, yes you can but they may get mushy given the time needed to safely can them.
Just getting into canning the extras from our garden.
It’s a fantastic way to preserve the bounty!
Potatoes can be raw-packed canned as long as they are kept in cold water up until the point of packing to prevent browning. Also, skins do not need to be removed, especially on red skin potatoes. The end result will be cloudy liquid, but it is harmless. Simply drain and cook potatoes to your liking. I have done both many times with a lot of success and with guidance from the Ball Blue Book of Canning.
Hi Amber, what is the publish date on the Ball Book of Canning that you are using? Every single current source I have read does not list raw pack or leaving the peels on. My Ball book was published in 2006 and specifically says to peel and hot pack. The National Center for Home Food Preservation also requires peeling and a hot pack process.
I do know that canning methods/best practices often change so it would be worth a look at which edition are you are using.
can I use my instapot in place of a pressure canning pot?
Unfortunately no. It is not large enough and not safe for canning.
I do have a tutorial for how to freeze potatoes if you don’t have a pressure cooker: https://www.sustainablecooks.com/can-you-freeze-potatoes/
