How to Make Canning Sweet Potatoes
Experience the satisfaction of transforming fresh sweet potatoes into a shelf-stable delight. This simple canning process preserves their natural sweetness and tender texture, making them an effortless addition to weeknight meals. With a preparation time of approximately 1 hour for canning, this recipe is your gateway to a consistently delicious pantry.
Step-by-Step Instructions
1. Prepare the Sweet Potatoes:
Begin by selecting firm, unblemished sweet potatoes. Wash them thoroughly under running water to remove any dirt. You can choose to peel the sweet potatoes or leave the skins on, depending on your preference. For easier handling during the peeling and cutting process, you can semi-cook the sweet potatoes. Place them in a large pot of water and boil until they are just tender enough to pierce with a fork but not mushy. This usually takes about 20-30 minutes for medium-sized potatoes. Once slightly cooled, peel them if desired, and cut them into uniform chunks or slices, approximately 1 inch in size. Uniformity is key to even cooking during the canning process.
2. Prepare the Jars and Equipment:
While the sweet potatoes are cooling, sterilize your canning jars, lids, and bands. You can do this by washing them in hot, soapy water and then placing them in a boiling water bath for at least 10 minutes, or by running them through a dishwasher cycle on a hot setting. Keep the jars hot until you are ready to fill them to prevent breakage. Prepare your canner or large stockpot by filling it with enough water to cover the jars by at least 1 inch. Bring this water to a simmer. Have your jar lifter, funnel, ladle, and damp cloth ready for use.
3. Pack the Jars:
Carefully place the prepared sweet potato chunks into the hot, sterilized canning jars. Pack them firmly but avoid smashing them. Leave about 1 inch of headspace at the top of each jar – this is the space between the food and the rim of the jar. If you are using lemon juice to help maintain the sweet potatoes’ color (it helps prevent them from turning brown in the jar), add 1 tablespoon of lemon juice to each pint jar.
4. Add Hot Water and Remove Air Bubbles:
Ladle boiling water over the sweet potatoes in the jars, ensuring all pieces are submerged and maintaining the 1-inch headspace. Use a non-metallic utensil, such as a plastic spatula or chopstick, to gently run around the inside of the jars. This helps release any trapped air bubbles and ensures a good seal. Add more boiling water if necessary to maintain the 1-inch headspace after removing air bubbles.
5. Wipe Rims and Seal Jars:
Using a damp cloth, carefully wipe the rim of each jar to remove any food particles or residue. This is crucial for a proper seal. Place a new, warm lid onto each jar and screw a band on fingertip-tight. Do not overtighten the bands, as air needs to escape during processing.
6. Process the Jars:
Using the jar lifter, carefully place the sealed jars onto the rack in your simmering canner. Ensure the jars are not touching one another. Once all jars are in the canner, add more hot water if needed to ensure the jars are covered by at least 1 inch of water. Bring the water to a rolling boil. Once the water is boiling vigorously, begin the processing time according to your altitude:
* 0-1,000 feet: Process pint jars for 1 hour and 30 minutes.
* 1,000-3,000 feet: Process pint jars for 1 hour and 45 minutes.
* 3,000-6,000 feet: Process pint jars for 2 hours.
* Above 6,000 feet: Process pint jars for 2 hours and 15 minutes.
Note: Quart jars require an additional 15 minutes of processing time for each altitude level.
7. Cool Jars:
When the processing time is complete, turn off the heat and remove the canner lid. Let the jars sit in the hot water for another 5 minutes before carefully removing them with the jar lifter. Place the hot jars upright on a towel-lined counter or cooling rack, ensuring there is space between them to allow for air circulation. Let them cool undisturbed for 12-24 hours. You will hear popping sounds as the lids seal.
8. Check Seals and Store:
After the cooling period, check each lid to ensure it has sealed. Press down on the center of the lid; it should not flex or pop. If a lid has not sealed, refrigerate the jar and use its contents within a few days, or reprocess the jar with a new lid. Remove the bands from the sealed jars, as this can cause them to rust. Wipe the jars clean and store them in a cool, dark, dry place.

Storing and Reheating Tips
Properly stored, your canned sweet potatoes will remain fresh and delicious for up to 12-18 months. It is essential to store the sealed jars in a cool (ideally between 50-70°F), dark, and dry place. Avoid extreme temperature fluctuations, which can compromise the seal. Before storing, ensure the bands are removed from the jars to prevent rust and allow for easy detection of any failed seals.
To reheat your canned sweet potatoes, simply open a jar and drain any liquid. You can gently heat them in a saucepan over low heat, adding a splash of water, broth, or a touch of butter if desired, until warmed through. Alternatively, they can be transferred to a microwave-safe dish and heated in the microwave. For best results and optimal flavor, it’s recommended to consume visually appealing and well-sealed jars within the recommended timeframe. If any jar shows signs of spoilage, such as a bulging lid or off odor, discard its contents immediately.
