How to Can Potatoes Safely: Complete USDA Guide for Home Preservation 2025


  • Total Time: 90 minutes
  • Yield: 8-10 jars 1x

Description

Learn how to safely can potatoes at home with USDA-approved pressure canning methods. Preserve your harvest for up to 12 months while retaining nutrients, texture, and flavor for easy, ready-to-use meals year-round.


Ingredients

Scale
  • 10 pounds potatoes (Russets or Yukon Golds recommended)
  • 4 cups filtered water (per quart jar)
  • 1 teaspoon canning salt (per quart jar)
  • 1 tablespoon lemon juice (per quart jar)
  • Optional: 1/4 teaspoon garlic powder per jar
  • Optional: 1/4 teaspoon black pepper per jar
  • Substitution Tips:
  • Use pure sea salt without additives
  • Fresh lemon juice may replace bottled if strained
  • Avoid table salt with anti-caking agents

Instructions

  1. Sanitize jars and lids using boiling water or the dishwasher’s sanitize cycle.
  2. Wash, peel, and cut potatoes into 1–2 inch pieces. Submerge in cool water to prevent discoloration.
  3. Blanch cubed potatoes in boiling water for 2–5 minutes (10 minutes for whole). Drain well.
  4. Cool slightly to prevent thermal shock during packing.
  5. Add 1 teaspoon salt and 1 tablespoon lemon juice to each quart jar.
  6. Pack hot potatoes into jars, leaving 1 inch headspace.
  7. Pour in fresh boiling water to cover, maintaining 1 inch headspace. Do not use blanching water.
  8. Wipe jar rims clean and secure lids fingertip-tight.
  9. Process jars in a pressure canner at 10 lbs pressure (11 lbs dial gauge), adjusting for altitude.
  10. Process pints for 35 minutes and quarts for 40 minutes following manufacturer guidelines.
  11. Allow pressure canner to cool naturally. Remove jars and cool 12–24 hours.
  12. Check seals, label jars with date, and store in a cool, dark place for up to 12 months.

Notes

Always peel potatoes before canning to ensure safety. Never water bath can potatoes—they require pressure canning. Store sealed jars between 50–70°F for best quality. Once opened, refrigerate and use within 3–4 days.
