Ingredients
Scale
- 10 pounds potatoes (Russets or Yukon Golds preferred)
- 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)
- Substitutions:
- Use white vinegar instead of lemon juice if preferred
- Try dried rosemary, thyme, or bay leaves for flavor
- Red or fingerling potatoes may be used, though texture softens slightly
Instructions
- Sanitize all jars, lids, and bands by boiling or running through the dishwasher’s sanitize cycle.
- Wash and peel potatoes, removing any eyes or blemishes. Cut into 1–2 inch uniform pieces.
- Bring a large pot of water to a rolling boil and blanch potatoes for 2–5 minutes until slightly tender but firm.
- Drain and cool slightly, patting dry to remove excess moisture.
- Add 1 teaspoon canning salt, 1 tablespoon lemon juice, and optional seasonings to each quart jar.
- Pack blanched potatoes into jars, leaving 1 inch headspace for proper sealing.
- Pour fresh boiling water over potatoes to cover, maintaining 1 inch headspace. Remove air bubbles.
- Wipe rims clean, apply lids, and tighten bands fingertip-tight.
- Place jars in a pressure canner and process pints for 35 minutes or quarts for 40 minutes at 10 lbs pressure (adjust for altitude).
- Allow canner to cool naturally before removing jars. Do not force-cool.
- Let jars cool undisturbed for 12–24 hours. Check seals and label with contents and date.
- Store sealed jars in a cool, dark place for up to 12–18 months.
Notes
Always use a pressure canner for potatoes—never a water bath. Ensure jars have 1 inch headspace and are properly sealed. Store between 50–70°F for best quality. Once opened, refrigerate and use within 3–4 days.
