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.

While this post is specific to white or baby potatoes, if you’re looking for a tutorial on canning sweet potatoes, check out our post on how to can sweet potatoes.

CANNING SUPPLIES FOR Canning Potatoes

Canning Prep

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˚F 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.

Preparing Potatoes for Canning

Rinse and scrub your potatoes. Peel, and rinse again.

For canning diced potatoes – cut peeled potatoes into 1/2-inch cubes and rinse. Cook in boiling water for 2 minutes and drain. 

For canning whole (baby) potatoes – choose small potatoes 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. Fill a medium to large saucepan with clean water and bring to a boil.

Add the hot potatoes to the jars. Pro tip: wiggle the jar often as you add them to allow them to settle and make room for more. You can also gently tap the jar on the counter as you fill them.

Using a canning funnel, carefully and slowly add the 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 them to fingertip tight.

How to Pressure Can Potatoes

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!).

4 steps in pressure canning

Processing times will vary based on altitude. See the chart below.

Processing Time for White Potatoes in a Weighted-Gauge Pressure Canner

Canner Pressure (PSI) at Altitudes of:
Style of Pack Jar Size Processing Time 0-1,000 ft Above 1,001 ft
Hot Pints 35 min 10 lb 15 lb
Quarts 40 min 10 lb 15 lb
*Source: National Center For Home Food Preservation

When the dial gauge reaches the appropriate PSI, reduce the burner temp to medium, and start your timer. The pressure must stay at the PSI 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 of the canner. (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 carefully lift them out with canning tongsPro 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.

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.

WHAT IF MY JARS DON’T SEAL?

If you’ve correctly processed the potatoes, and the lids still didn’t seal, you can reprocess them.

Double-check to make sure there are no:

  • Chips in the rim of the jar
  • Dried bits of potato on the rim (anything between the rim and the lid may prevent a seal.

Best practices would involve using brand-new lids for reprocessing. Set aside the old lids to use for dry storage (related: Pantry Essentials for the Home Cook).

If the jars don’t seal on the second attempt, you likely have a bad batch of lids, or your canning process has a step missing. Email me and we’ll try to troubleshoot what is going on.

HELP! WHY ARE MY JARS LEAKING Water?

If you find that water has leaked out after they have sealed, you have experienced a common canning issue called siphoning. It happens to the best of us!

Siphoning is typically caused by not allowing the jars to rest in the canner after they have finished processing. In the directions, you’ll see that I recommend you remove the canner from the burner, remove the lid, and let it sit for 5 minutes.

This is important as it allows the jars time to rest before being allowed to cool on the counter. Doing this process will significantly cut down on siphoning.

IF YOU HAVE SIPHONING IN YOUR JARS, FOLLOW THESE STEPS:

  • Check – are the lids still sealed?
  • Look – have you lost less than half of the amount of liquid in the jar?
  • Examine – do the potatoes look fresh with bright colors?

If the answer to the above three steps is “yes!”, then they are safe to eat. If you lost quite a bit of liquid, the uncovered potatoes will turn color more quickly. Plan to eat those jars first.

STORAGE FOR HOME CANNED Potatoes

Once the jars have sealed, remove the rings. Label and store sealed jars in a cool (best results are 50-70˚F) dark place for up to 12-18 months.

If you have the space available, do not stack the jars on top of each other more than two jars high.

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.

HOW MANY POTATOES DO YOU NEED FOR CANNING?

Overall you’ll need about 2.5 pounds of potatoes (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.

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. 

Do You Have to Blanch Potatoes Before Canning?

Nope! Blanching involves par-cooking and then placing the produce into frozen water to stop the cooking process. This is necessary for freezing potatoes but not canning them.

Instead, you’re cooking the potatoes and then placing them in the jars while they’re still hot.

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.

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.

Pro Tips/Recipes Notes

  • As you prep your potatoes, add them to a large bowl of ice water to keep them from browning. 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.

  • Allow the steam to pass through for about 10 minutes. Then put the pressure regulator on top.
  • Pretty soon, the air vent will pop up.
  • In a dial-gauge pressure canner, process pints and quarts based on the elevation guide below (see processing chart in post for additional altitude adjustments):
    *0-2,000f ft {PSI: 11 lbs of pressure} = Pints 35 min, Quarts 40 min
    *2,001-4,000k ft {PSI: 12 lbs of pressure} = Pints 35 min, Quarts 40 min
    *4,001-6,000k ft {PSI 13 lbs of pressure} = Pints 35 min, Quarts 40 min
    *6,001-8,000k {PSI 14 lbs of pressure} = Pints 35 min, Quarts 40 min
  • When the dial gauge reaches the appropriate PSI, reduce the burner temp to medium, and start your timer. The pressure must stay at the PSI or (a little bit) above for the duration of the cooking time.
  • 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 of the canner (Pro tip: use oven mitts to 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.
  • Place on a thick clean towel 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.

Notes

  1. Store in a cool dark place for 12-18 months.
  2. 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.

  1. I’m doing my taters now, using your tips. Warning, 20 lbs did 7 quarts and 8 pints. With almost 5 lbs leftover. Chopped small for hashbrowns.
    Also I have been referring to my Bernardin book as your process times don’t match with there’s for altitude. So I used your tips and their method. Hopefully they turn out well.
    I have been pressure canning for 13 years. So I am aware of the process. I appreciate the tips.4 stars

    1. Hi Dee, what year is the publication date on that book? The sources I use are a university extension that is pretty deep into canning education. I just double-checked and their times were reviewed in 2018. Would be interesting to see the differences in the times/publication date.

  2. I am confused, I put the canner on the stove to high and boil the water. Is there a certain amount to put in? Once it is boiling do I use that water to put in jars? And how much water to put in the canner for the jars? Is it the same water that was boiling, did I add to it, did I replace it? And once that is all answered, I put the lid on the canner while boiling the water with the jars in and leave it on high? It’s on high with lid on and no weight, does it get to pressure then lower the heat and add the weight ?
    Sorry if it’s a dumb question. 

    1. Hi Uncle, the answers to all of your questions are actually in the printable recipe card in the post. I’m going to copy and paste them below, so it might look a bit jumbled. Bear with me on this!

      Q: Is there a certain amount to put in?
      A: (step 6 in the recipe card): 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.

      Q: Once it is boiling do I use that water to put in jars?
      A: (step 8 in the recipe card): 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. (note: in this instance you can use a separate pot of clean water, an electric kettle, etc.)

      Q: And once that is all answered, I put the lid on the canner while boiling the water with the jars in and leave it on high? It’s on high with lid on and no weight, does it get to pressure then lower the heat and add the weight ?
      A: (these are answered in multiple parts of the recipe card so I’m going to copy and paste them all below for clarity):
      (step 12 in the recipe card): Using canning tongs, gently place the jars in the canner. Lock the lid. Soon, steam will start coming through the vent pipe.
      (step 13 in the recipe card): Allow the steam to pass through for about 10 minutes. Then put the pressure regulator on top. (the pressure regulator is essentially what you’re calling the weight)
      (step 16 in the recipe card): When the dial gauge reaches the appropriate PSI, reduce the burner temp to medium, and start your timer. The pressure must stay at the PSI or (a little bit) above for the duration of the cooking time.

      I hope that clarifies it a bit. If not, please feel free to email me directly at sarah@sustainablecooks.com. Maybe send me a photo of your canner and I can be more specific to your exact model.
