How to Can Peaches at Home

Canning peaches preserves summer's best fruit for year-round enjoyment. You'll need ripe but firm peaches, sugar syrup or juice, sterilized jars, and a boiling water bath. The process involves peeling peaches, packing them in jars with syrup, and processing in boiling water for 20-30 minutes depending on jar size. Properly canned peaches keep for up to a year in a cool, dark place.

Total time: 1 hr 15 min
Hands-on: 30 min
Difficulty: Medium

Ingredients

2 cups sugar
4 cups water

Step by step

Prepare your equipment. Sterilize canning jars and lids in boiling water for 10 minutes. Set up your boiling water bath canner with enough water to cover jars by 2 inches. Keep jars hot until ready to fill.
Prepare the peaches. Bring a large pot of water to boil. Drop peaches in for 60 seconds, then immediately transfer to ice water. The skins will slip off easily. Cut peaches in half, remove pits, and slice if desired.
Make your syrup. Combine 2 cups sugar with 4 cups water for light syrup, or use fruit juice. Heat until sugar dissolves. Keep hot but not boiling. You can also pack peaches in their own juice without added sweetener.
Pack the jars. Place peach halves cut-side down in hot jars, overlapping slightly. Leave 1/2 inch headspace. Pour hot syrup over peaches, maintaining headspace. Remove air bubbles by sliding a knife around the inside edge.
Seal and process. Wipe jar rims clean, place lids, and screw on bands finger-tight. Process in boiling water bath: 20 minutes for pints, 25 minutes for quarts at sea level. Add 5 minutes for every 3,000 feet of elevation.
Cool and test seals. Remove jars and cool on a towel for 12-24 hours. Check that lids have sealed by pressing the center - they shouldn't pop back. Unsealed jars go in the refrigerator for immediate use.

Tips & troubleshooting

Choose freestone peaches that give slightly to pressure but aren't mushy - they hold their shape better during processing
Add 1/4 teaspoon citric acid or 1 tablespoon lemon juice per quart to maintain color and prevent browning
Work quickly once peaches are peeled to prevent browning, or keep them in water with lemon juice
Don't overtighten jar bands - gases need to escape during processing for proper sealing
Store sealed jars in a cool, dark place and use within one year for best quality

Variations

Spiced Peaches. Add a cinnamon stick, 3 whole cloves, or 1/4 teaspoon ground ginger to each jar before adding syrup for warm, aromatic peaches perfect for winter desserts.
Honey Peaches. Replace sugar syrup with a mixture of 1 cup honey dissolved in 3 cups water. The honey adds floral notes and creates a more complex sweetness.
No-Sugar-Added. Pack peaches in white grape juice, apple juice, or water instead of sugar syrup. The peaches will be less sweet but retain more of their natural flavor.

Questions

Can I use frozen peaches for canning?: Fresh peaches work best because freezing breaks down cell structure, making them mushy after canning. If using frozen, thaw completely and drain excess liquid before packing.
What if my peaches float in the jars?: Floating fruit is common and doesn't affect safety. Choose firmer peaches, pack more tightly, or use a hot pack method where you heat peaches in syrup before jarring.
How do I know if the seal failed?: Check after 24 hours of cooling. A proper seal won't pop back when pressed. You'll also hear a 'ping' sound as jars cool and seal. Failed seals mean refrigerate and use within a week.
Can I reprocess jars that didn't seal?: Yes, within 24 hours. Use a new lid and reprocess for the full time. Or remove the lid, refrigerate, and eat within a week rather than reprocessing.
