Best Types Of Potatoes For Canning
The best type of potatoes for canning are mostly the red, thin skinned white, and gold varieties.

These types are often called “waxy” or “boiling” potatoes, and tend to be lower in starch.
Small new potatoes are also a good option because of their firm flesh and thin skin.
Preparing Potatoes For Canning
Preparing potatoes for canning is simple. First, wash and peel them, then cut them into 2” cubes. If you prefer, you could leave them whole if they’re 2” around or smaller.
As you chop them up, place the pieces into a pot of cold water. This encourages more of the starches to leach out, as well as preserves the color.
Once you’re done, use a colander to drain and rinse them. Next, par-boil them for about 10 minutes. Then, reduce the heat, and keep them warm until you’re ready to place them into the jars.

Processing Canned Potatoes
Since they are a low acidic food, the only safe way to process potatoes is using a pressure canner.
The water bath method is not safe because it can’t get them hot enough to kill all of the harmful bacteria.

How To Store Canned Potatoes
Check the seal of your canned potatoes before storing them. You can do this by pressing the center of the lid to ensure each one has a proper seal. If it moves at all, that means it did not seal.
In that case, you just need to put them into the fridge, and use those up first.
Otherwise, store them somewhere cool and dark. Places like the pantry, a cupboard, or your basement are all great choices.

You should not can potatoes with the skins on, due to the risk of bacteria contamination. Modern food safety standards require them to be peeled before canning.
Can you water bath canned potatoes?
You can’t safely water bath canned potatoes because of their low acidity levels. They must be processed at a much higher temperature, which can only be achieved using a pressure canner.

How To Can Potatoes
Canning fresh potatoes is easier than you might think, and doesn’t take much time. Follow the step by step instructions below to learn exactly how to hot pack and process them.
Ingredients
- 9 pounds potatoes (about 18 medium)
- 5 cups water
Instructions
- Prepare your pressure canner - Place the rack into the pressure canner, then fill the bottom with 2-3” of boiling water, or per your canners user manual. Different models may vary.Pack the jars - Add your hot potatoes into each canning jar, taking care not to squish them as you pack them in, and leaving a 1 ½“ headspace on top.Add boiling water - Use your funnel and ladle to pour boiling water over the potatoes to fill each jar, keeping 1” of headspace on top.Remove air bubbles - Use a bubble popping tool or wooden skewer to remove any air bubbles present in the jar. Don’t use anything metal for this, as it can damage the glass.Place the lids and rings on - Wipe the rim of each jar with a warm damp paper towel. Then place a new lid and ring on top, and twist just enough to secure them, while not over tightening.Place the jars into the pressure canner - Use your lifting tool to carefully place the jars into the canner right after filling them, so they don’t have a chance to cool down.Put the lid on the canner - Once all of the jars are inside, place the lid on your pressure canner, lock it into place, and bring it to a boil on high heat.Process the jars - Let the canner vent for 10 minutes before closing it. Continue heating to reach 11 PSI for a dial gauge, and 10 PSI for a weighted gauge. Then process the jars for 35 minutes.Remove the jars - Turn off the heat and allow the canner to cool completely before opening it and removing the jars. Don’t take the bands off until the jars are room temperature. This can take 30 minutes.Cool and label them - Let the jars sit until they reach room temperature, then remove the bands and label them. You can either write on the tops with a permanent marker, or use dissolvable labels.
