How to Pressure Can Dried Beans in Canada (Bernardin Method)

Pressure-canned beans are the cheapest protein in a Canadian pantry. A 1 kg bag of dried navy beans is ~$4 at any Canadian grocer; soaked, cooked, and canned, that bag becomes 8-10 × 500 mL jars worth about $35 of equivalent commercial canned beans. The math is unbeatable.

This guide covers the Bernardin method for plain pressure-canned beans (the kind that replace a tin of Aylmer or Heinz beans). For bean-and-tomato or bean-and-pork preserves see Bernardin’s specific recipes — those have different processing rules.

What you need

For 6-8 × 500 mL jars:

• 500 g dried beans (about 2.5 cups dry) — navy, kidney, pinto, black, romano, or great northern
• Water for soaking — about 4 L
• Water for cooking — about 4 L
• Boiling water for jarring — about 1 L fresh boiling water
• Optional: pickling salt — ½ tsp per 500 mL jar, 1 tsp per 1 L
• Bernardin 500 mL OR 1 L jars — wide-mouth preferred for ease of packing
• Fresh SNAP lids and bands
• Pressure canner (Presto 23-quart or All American 921)
• Standard canning kit plus large pot for the soak and cook

Pick your beans

Most Canadian-available dried beans work for pressure canning:

• Navy beans — small white beans; the Heinz beans-and-pork bean. Ontario is a major North American producer.
• Great northern — larger white beans; good for soup and casseroles
• Kidney beans (light red, dark red, white kidney/cannellini) — chili, salads
• Pinto — refried beans, Tex-Mex
• Black beans — Latin and Caribbean cuisines
• Romano (cranberry beans) — Italian-style, beautiful speckled appearance fades during canning
• Pink beans — Latin cuisines
• Saskatchewan dry beans — high-quality Canadian-grown; look for Saskatchewan Pulse Growers branding

Skip for pressure canning:

• Lentils — too small; cook too fast; not safe with the 90-minute pressure protocol
• Mung beans — different cook times
• Adzuki — different cook times
• Soybeans — Bernardin doesn’t have a tested plain-soybean recipe
• Lima beans — special Bernardin recipe with shorter processing; check the book

For a starter batch, navy or kidney beans are the safest, most-used Canadian options.

Method

Step 1: Overnight soak (or quick-soak)

Option A — Overnight soak (preferred):

1. Rinse beans in a colander. Remove any stones or shrivelled beans.
2. Place in a large bowl, cover with cold water by at least 5 cm.
3. Soak 8-12 hours (or overnight at room temperature).
4. Drain and rinse.

Option B — Quick-soak:

1. Rinse beans.
2. Place in a large pot, cover with water by 5 cm.
3. Bring to a boil. Boil 2 minutes.
4. Remove from heat. Cover. Let stand 1 hour.
5. Drain and rinse.

Both methods produce the same result. Overnight is easier; quick-soak is faster.

Step 2: Pre-cook the beans

1. Place drained soaked beans in a large pot.
2. Cover with fresh water by 5 cm.
3. Bring to a boil.
4. Boil 30 minutes, skimming any foam. The beans will be partially cooked but still firm.
5. Drain.

Why pre-cook? The boil partially hydrates the bean centres so heat penetration during pressure canning is even. Skipping this step risks unsafely under-processed beans.

Step 3: Pack the jars

1. Have the pressure canner with 7-8 cm of hot water and the rack inside, ready.
2. Have hot 500 mL or 1 L jars on the counter.
3. Pack hot beans loosely into jars to 75% full — about 1 cup of beans per 500 mL jar, 2 cups per 1 L jar.
   • Don’t over-pack — beans expand further during processing and need room.
4. Optional: add 1 tsp pickling salt per 1 L jar (½ tsp per 500 mL).
5. Optional: add 1 small garlic clove and/or 1 bay leaf to each jar.
6. Pour fresh boiling water over beans to cover, leaving 2.5 cm (1 inch) headspace.
7. Run the headspace tool down the inside of each jar to release air bubbles. Top up water if needed.
8. Wipe rims with a clean damp cloth.
9. Apply fresh SNAP lids fingertip-tight.

Step 4: Process

1. Lower jars into the canner. Water should be at 7-8 cm — not covering jars.
2. Lock the lid. Heat on high.
3. Vent for 10 full minutes. Critical safety step.
4. Apply the regulator. Bring to 10 PSI at sea level.
5. Process:
   • 1 L jars: 90 minutes at 10 PSI
   • 500 mL jars: 75 minutes at 10 PSI
6. Maintain pressure throughout. If it drops, restart the timer.

Step 5: Cool and check

1. Turn off heat. Don’t move the canner.
2. Let depressurize naturally — 45-60 minutes. Never force-cool.
3. Once at zero PSI, remove the weight, wait 10 minutes, unlock the lid.
4. Lift jars with the jar lifter. Cool 12-24 hours undisturbed on a towel.
5. Check seals. Label, store.

If a jar doesn’t seal: the 24-hour rule applies.

Altitude adjustments

Altitude	Weighted gauge	Dial gauge
0 – 305 m	10 PSI	11 PSI
305 – 610 m	15 PSI	12 PSI
610 – 1,220 m	15 PSI	13 PSI
1,220+ m	15 PSI	14 PSI

Times stay 90/75 minutes; PSI changes. See the Canadian altitude table.

Storage and use

• Cool, dark, dry place at room temperature
• Best quality 12-18 months
• After opening: refrigerate, use within 5-7 days
• Inspect every jar before opening — bulging lid means discard

To use

A 500 mL jar of pressure-canned beans is equivalent to a standard 540 mL commercial can. Drain and rinse (or don’t — the liquid is bean broth and can be used) and use anywhere you’d use canned beans:

• Chili — add directly to the chili pot
• Bean soup — straight in
• Baked beans — drain, combine with maple syrup, brown sugar, mustard, ketchup; bake or simmer
• Refried beans — drain, mash, fry with onion and garlic
• Salads — drain, rinse, toss with vinaigrette
• Bean burgers — drain, mash, mix with breadcrumb and seasoning, pan-fry
• Dips — bean dip, white bean dip, black bean dip
• Three-bean salad — three different bean varieties + vinaigrette
• Hummus alternative (white bean) — blend with garlic, lemon, olive oil
• Pasta and beans (pasta e fagioli) — open jar, drop in
• Burritos and quesadillas — drain, mash slightly, fill

Variations

Beans with garlic and herbs

Add 1 small garlic clove + 1 bay leaf per jar. Very mild seasoning; safe under Bernardin protocol.

Spiced black beans

Add 1 small garlic clove + ½ tsp ground cumin per 500 mL jar. The cumin survives the long cycle better than fresh herbs.

Mixed bean medley

Soak and cook 3 varieties separately (different bean types absorb water differently). Pack mixed in jars.

Bean broth save

The liquid that beans pre-cook in is delicious. Strain it after the 30-minute boil; can it separately in 500 mL jars at 25 minutes / 10 PSI as a soup base. Or use the bean broth in place of plain water in the jars.

Refried beans (separate Bernardin recipe)

If you specifically want refried beans canned, follow Bernardin’s tested refried-bean recipe — it has different fat and seasoning rules and slightly different processing. Don’t substitute “refried” for “plain beans” in this protocol.

Common problems

• Beans floated to top. Normal — beans expand and the lighter ones rise. Cosmetic only.
• Beans split open. Some bean varieties split more than others; over-soaking can cause it. Cosmetic only.
• Cloudy liquid. Bean starch in the canning liquid; harmless.
• Beans hard at the centre. Soaked too briefly or skipped the 30-minute pre-cook. Beans should be soft after canning — if they’re crunchy, the process didn’t work. Re-soak and re-pre-cook before canning next batch.
• Liquid siphoned out (jar partially empty). Common with starchy foods. As long as seal is intact and most liquid remains, safe.
• Beans turned grey or dark. Hard water in canner can react with bean pigment. Use bottled or filtered water for the canning liquid. Cosmetic only.
• Jar didn’t seal. The 24-hour rule. Low-acid window is shorter.
• Bulging lid later. Discard immediately. Don’t open, don’t taste. Botulism warning sign.

Yield expectations

• 500 g dried beans → 6-8 × 500 mL jars OR 3-4 × 1 L jars
• A typical bean-canning session uses 1.5-2 kg dried beans (3-4 bags from the grocery) and yields 18-24 × 500 mL jars
• 24 × 500 mL jars at the rate of 2 jars per week = a 12-week supply

A 1 kg bag of dried navy beans at $4 → 12-16 jars worth ~$50 of commercial-equivalent beans. The math is dramatic.

Why home-canned beans are worth the time

• Cheapest protein you can put on the shelf — dried beans are the lowest-cost-per-gram protein at any Canadian grocer
• Better than commercial — you control salt, no preservatives, no BPA from can liners
• Convenience — same speed as opening commercial canned beans
• Pantry essential — base for chili, soup, refried beans, salads
• Heritage Canadian preserve — Saskatchewan farmstead and prairie homesteading tradition; pulses are a major Canadian agricultural export

Bean math (the case for canning)

Item	Cost	Yield equivalent
1 kg dried navy beans	$4	10-12 × 500 mL jars equivalent
1 × 540 mL commercial canned beans	$1.50-2.50	1 can
10 × commercial canned beans	$15-25	Same as 1 kg dried
Home-canning equipment one-time	$200-400	Lifetime

A pressure canner pays for itself in about 100-200 jars of home-canned beans alone — never mind the meat, soup, and stew it also enables. Most Canadian home canners hit the break-even point in 2-3 fall canning sessions.
