Preserving the bounty of your garden or taking advantage of a good sale at the farmer’s market isn’t limited to jams, jellies, and tomatoes. One of the most versatile vegetables you can preserve at home, the humble potato, is also a great candidate for home canning. If done correctly, home-canned potatoes can be a convenient, ready-to-use ingredient in many dishes, from hearty stews to comforting homemade potato salads.
Introduction to Canning Potatoes
Canning potatoes at home provides a range of benefits. Not only does this allow you to enjoy this starchy comfort food all year round, but it also proves handy during meal preps by cutting down on cooking time. The act of canning has been around for centuries as a method of food preservation intended to prolong the shelf life of produce and prevent spoilage. Canning potatoes involve a combination of cleaning, preparing, and using proper canning methods.
Some of the key reasons to can potatoes at home include:
- Convenience: Canned potatoes are pre-cooked and ready to use, helping you save time when preparing meals.
- Longevity: Canned potatoes last a lot longer than fresh ones, helping you reduce waste.
- Flavor Preservation: The canning process allows potatoes to retain their flavor and nutritional value.
Pro Tip: When it comes to canning, not all potatoes are created equal. The best types of potatoes for canning are high starch varieties known as ‘mealy’ potatoes. This includes russet and Idaho potatoes, which hold their shape well in high heat and pressure.
Preparing Potatoes for Canning
Just like any process involving food, preparation is the key. Start by thoroughly washing your potatoes to remove any dirt and other impurities. Then, using a peeler, remove the skin as dried potato skins can impact the taste. Cutting the potatoes into uniform cubes or slices helps ensure even cooking and easier packing into canning jars. Finally, soaking them in cold water helps remove excess starch, which can cause the water in the can to become cloudy.
Safety is paramount when preparing potatoes. Always make sure your hands and utensils are clean to avoid any cross-contamination.
Checklist: Materials needed to prepare potatoes
- Sharp knife
- Vegetable peeler
- Bowls
- Cutting board
Best Practices: Always discard any potatoes with green spots or those that are soft, sprouted, or have a strong smell as these are signs of spoilage. Also, be sure to leave about one inch of headspace in the can to allow for expansion during the canning process.
Pressure Canning Potatoes
Pressure canning is often recommended for low-acid foods like potatoes. The process involves placing filled jars into the canner, which is then sealed and heated to a specific temperature. This method kills microorganisms that could cause spoilage, ensuring the food is safe for long-term storage.
Here is a simple step-by-step guide on how to pressure can potatoes:
- Fill your pressure canner with appropriate water level according to your canner’s instruction manual and begin heating.
- Pack your prepared potatoes into clean jars, leaving 1 inch of headspace.
- Wipe the rims of the jars thoroughly, place the lids on top, and tighten the bands.
- Place jars into the canner using a jar lifter, ensuring they don’t touch each other.
- Lock the canner lid and begin heating. Allow the canner to vent for 10 minutes.
- After venting, bring the canner up to the correct pressure (10-15psi depending upon your altitude) and cook for 35-40 minutes.
- Once the canning time is over, turn off the heat and let the pressure drop naturally.
Pro Tip: Always refer to your pressure canner’s manual for instructions regarding the correct amount of headspace, processing time, and pressure level required.

Hot Water Bath Method
Another popular method for canning potatoes is the hot water bath method. This straightforward process involves submerging the filled jars in boiling water to kill off bacteria, yeast, and enzymes that could cause spoilage.
Checklist: Essential materials needed for the hot water bath method
- Large pot with a rack
- Canning jars, lids, and bands
- Jar lifter
- Clean towels
Pro Tip: Unlike pressure canning, the hot water bath method does not reach the higher temperatures necessary to destroy certain bacteria and enzymes. As such, it’s best used for acidic foods. If using this method for potatoes, consider adding an acid, like vinegar or lemon juice, to each jar.
Salt Brine Method
The salt brine method involves immersing potatoes in a salty brine before canning. This type of canning is best used for pickling and it adds a savory flavor to the potatoes, making them a unique addition to certain dishes.
List: Essential materials needed for salt brine method
- Canning jars, lids, and bands
- Large pot
- Salt (pure canning or pickling salt is best)
Pro Tip: A general rule of thumb for the ideal salt-to-water ratio in the brine is 2 tablespoons of salt for every quart of water.
Storing Your Canned Potatoes
Canned potatoes, whether using pressure canning, hot water bath, or salt brine methods, need to be stored properly to ensure their quality remains optimal. Store them in a cool, dark, dry place. The optimal storage temperature is below 70 degrees Fahrenheit.
Checklist: Steps to properly store your canned potatoes
- Allow jars to cool down after processing before storing.
- Label and date the jars.
- Check jars for seals. Any jars that didn’t seal properly during processing should be refrigerated and consumed within a week.
- Store in a cool, dark, and dry place out of direct sunlight.
Best Practices: Check jars periodically for spoilage, indicated by bulging lids, leakage, or any off smell. Never consume food from jars that show signs of spoilage.
Serving and Using Your Canned Potatoes
Canned potatoes are wonderful additions to a multitude of dishes. They’re particularly great for quick meals as they’re pre-cooked and therefore, shorten cooking times significantly.
Checklist: A range of dishes that work well with canned potatoes
- Home-made hash browns
- Potato chowder
- Mashes potatoes
- Curries or hearty stews
Pro Tip: Enhance the flavor of canned potatoes by sauteing them in butter or olive oil with some garlic and herbs before adding them to
