Peanuts, Boiled, Canned
Prep 3 hours soaking
Cook 45-50 minutes at pressure
Serves 6 quarts
Level Medium

🔴 Corrected 2026-07-30 — this recipe used to say 90 minutes. The tested process is 50 minutes for quarts, 45 for pints. See the notes; the short version is that it was over-processing by forty minutes, which is a texture problem rather than a safety one.

Shelf-stable boiled peanuts in a jar — the thing I have been buying at the Piggly Wiggly for thirty years, made at home. ⭐ Worth knowing how unusual this is: the National Center for Home Food Preservation has withdrawn its procedures for canning nut meats generally, and green peanuts are the single exception they still publish.

🔴 Low-acid food. PRESSURE CANNER ONLY. A boiling-water bath cannot reach the temperature required and an Instant Pot is a pressure cooker, not a pressure canner.

Ingredients

  • 6 lb fully mature GREEN peanuts in the shell — about 1 lb per quart jar
  • 1 cup canning or pickling salt per gallon of water, for the brine
  • 6 tsp Cajun seasoning, optional — 1 tsp per quart jar
  • Water

Directions

Key ingredients

Salt

  1. 🔴 Read this first — Boiled peanuts are a wet, low-acid, cooked food with no acid and no ferment. They must be pressure canned. A boiling-water bath tops out at 212°F, which does not destroy Clostridium botulinum spores, and a sealed jar of low-acid food at room temperature is exactly where those spores germinate. An Instant Pot or electric multicooker is a pressure COOKER and is not approved for canning low-acid foods.
  2. Use fully mature GREEN peanuts — Both halves matter: full-size and developed, but undried. Not immature, and not dried-raw.
  3. Soak three times, fresh water each time — Wash the peanuts. Soak in fresh water 1 hour, discard. Fresh water, 1 hour, discard. Fresh water, 1 hour, discard. Three hours total. This is not about flavour — peanuts carry field soil and surface starch, and three changes of water is how the tested process deals with that before the jars are sealed.
  4. Parboil 10 minutes — In fresh water. Drain.
  5. Sterilise the jars and lids — Jars in boiling water 10 minutes; lids per the manufacturer.
  6. Make the brine — 1 cup of salt per gallon of water, heated and held just below a boil so it does not reduce while you work.
  7. Pack hot — Hot peanuts into hot jars, 1/2 inch headspace. Fill to 1/2 inch from the top with the boiling brine. Add the Cajun seasoning now if using. Remove air bubbles, wipe the rims, adjust the lids.
  8. 🔴 Process — the corrected times — DIAL GAUGE: pints 45 minutes, quarts 50 minutes at 11 lb (0-2,000 ft), 12 lb (2-4,000), 13 lb (4-6,000), 14 lb (6-8,000).
  9. WEIGHTED GAUGE: pints 45 minutes, quarts 50 minutes at 10 lb below 1,000 ft and 15 lb above 1,000 ft.
  10. 🔴 Check your own elevation — the difference between 10 and 15 lb is the difference between a safe jar and an unsafe one.
  11. Vent, then time — Let the canner vent steam 10 minutes to purge the airspace before adding the weight. Start the timer only once the gauge reaches pressure, and hold it there.
  12. Cool without hurrying it — Turn off the heat and let the pressure fall to zero on its own before opening. Lift the jars out and cool on a towel without bumping them. Check the seals the next day.

🔴 WHAT CHANGED, AND WHY I AM SAYING SO RATHER THAN QUIETLY EDITING IT. This recipe previously specified 10 lb of pressure for 90 minutes. Everything else in it — the three soaks, the ten-minute parboil, the 1/2 inch headspace, the one-cup-per-gallon brine — matches the tested NCHFP process exactly, so the 90 was the one number that had drifted.

It is not a safety error. Ninety minutes at 10 lb comfortably exceeds the lethality the process requires; jars canned that way are fine, and erring long is the safe direction to err. But it is forty extra minutes of retort-temperature cooking on a food whose entire virtue is texture — peanuts that go into the jar creamy come out closer to paste. I had been wondering for years why my home-canned ones never matched the jarred ones from the store.

⚠ The general lesson: if a canning recipe’s times do not match the tested process, work out which direction the discrepancy runs before doing anything. Longer than tested is a quality problem. Shorter than tested is a botulism problem. They are not symmetrical.

If you would rather not can them, freeze them — for home use freezing preserves the texture better than canning does, needs no special equipment, and carries none of the risk. Canning earns its place when you specifically want a shelf-stable jar.

Keeping them. Boiled peanuts are a wet, cooked, LOW-ACID food with no acid and no ferment — they are not a pickle and nothing in them preserves them. Refrigerate within two hours of the pot coming off the heat and eat within about four days, stored in their brine. They freeze extremely well in their liquid. To can them you need a PRESSURE canner and the tested process — never a boiling-water bath, and never an Instant Pot, which is a pressure cooker and not a pressure canner.
