How to Make Pickled Banana Peppers in Canada (Bernardin Method)

Banana peppers are the friendliest pepper to pickle. The sweet ones carry no real heat, so a jar goes on sandwiches, submarine buns, pizza, and salads without scaring anyone off — and the hot (Hungarian wax) type pickles exactly the same way when you want some warmth. They’re cheap by the basket at Ontario and Prairie farmers’ markets from late July through September (growing peppers in Canada).

This page follows Bernardin’s Pickled Sweet Peppers, which is the recipe that covers banana peppers — their own headnote names sweet, banana, Hungarian and Italian peppers together, with jalapeños as an optional accent. Every quantity, time and temperature below is transcribed from that page. Where we explain why a step works, or suggest something Bernardin does not (the sugar-versus-vinegar note, the optional Pickle Crisp, the refrigerator ring variation), it is marked as ours.

Corrected 31 Aug 2026: this page previously gave a 1:1 brine — 3 cups vinegar to 3 cups water, packed the peppers as sliced rings, put 2 tbsp pickling salt in the brine, published a processing time for 1 L jars, and carried an invented “never drop below” vinegar floor of our own. None of that was Bernardin’s. Their tested recipe is a 5:1 brine — 10 cups vinegar to 2 cups water — on whole slit peppers after a 12–18 hour salt soak, with no salt in the brine, in 500 mL jars only. Our old brine was substantially more dilute than the tested one: about 2.5% acetic acid against roughly 4.2%, before their 15-minute uncovered boil concentrates it further. On a low-acid vegetable the vinegar is the only barrier, so the ratio is the safety figure. The invented vinegar floor is gone; it was our number sitting under a Bernardin attribution.

What you need

For about 8 × 500 mL jars:

• 1 × 4 qt (4 L) basket banana peppers — sweet, hot, or a mix
• 1½ cups (375 mL) pickling salt — for the soak, and thrown away with it
• 16 cups (4 L) water — for the soak
• 10 cups (2500 mL) white vinegar (5% acidity — do not substitute a weaker vinegar)
• 2 cups (500 mL) water — for the brine
• 4 tbsp (60 mL) granulated sugar
• 2 tbsp (30 mL) prepared horseradish
• 2 garlic cloves — boiled in the brine, then removed
• Bernardin 500 mL jars, fresh SNAP lids, bands
• Standard canning kit — jar lifter, headspace tool, funnel, water-bath canner, ladle

There is no salt in the brine and no firming agent in the jar. Both jobs are done by the soak.

The acidity rule comes first

Banana peppers — like all peppers — are a low-acid vegetable. They are only safe in a water-bath canner because the vinegar brine drops the whole jar well below the pH 4.6 line where Clostridium botulinum can grow. That means two non-negotiables:

• Use Bernardin’s ratio — 10 cups vinegar to 2 cups water — with 5% vinegar. Five parts vinegar to one part water is the tested balance, and it is not a ratio to adjust for taste. The ratio is theirs; the 5% strength is this site’s convention, since Bernardin specifies white vinegar without stating a percentage. Shifting it toward water dilutes the only thing keeping the jar safe.
• Never water-bath plain (unpickled) peppers. Peppers with no vinegar must be pressure canned — see the pressure-canning pillar. This recipe is safe because it’s a pickle.

Method

Step 1: The salt soak (start the day before)

Bernardin’s recipe is a two-day recipe. The soak is the whole first day, and skipping it is not a shortcut — it is a different recipe.

1. Wash the banana peppers thoroughly under cool running water; drain.
2. Cut two small slits in each pepper. They stay whole — do not slice them into rings. (See ring-cut peppers below for why.)
3. Place them in a large stainless steel or glass container — not aluminum.
4. Dissolve 1½ cups (375 mL) pickling salt in 16 cups (4 L) water. Pour it over the peppers.
5. Let stand 12 to 18 hours in a cool place.
6. Next day: drain, rinse in cool running water, and drain thoroughly.

The soak is thrown away — none of that salt reaches the jar. It draws water out of the pepper wall, which is what keeps the finished pickle firm. That is also why Bernardin’s brine contains no salt at all, and why the recipe needs no added firming agent.

If you’re using hot banana peppers, wear gloves from the slitting step onward — capsaicin transfers to skin.

Step 2: Heat the jars

1. Place 8 clean 500 mL jars on a rack in the water-bath canner, cover them with water, and heat to a simmer at 82 °C. Keep them hot until you fill them.
2. Do not preheat the SNAP lids — Bernardin advises against it. Wash them in hot soapy water, dry, and set aside.

Step 3: Make the brine (five parts vinegar to one part water)

In a large stainless steel saucepan, combine:

• 2 cups (500 mL) water
• 10 cups (2500 mL) white vinegar (5% acidity)
• 4 tbsp (60 mL) granulated sugar
• 2 tbsp (30 mL) prepared horseradish
• 2 garlic cloves

Bring to a boil, then reduce the heat and boil gently, uncovered, 15 minutes. Remove the garlic cloves before filling.

Look at the ratio: 10 cups vinegar to 2 cups water — five parts vinegar to one. Banana peppers are a low-acid vegetable, and the vinegar is the only thing making the jar shelf-safe. This is not a ratio to adjust for taste. Our note, not Bernardin’s: if the result is sharper than you want, the lever is the sugar, not the vinegar.

There is no salt in the brine. All the salt in this recipe is in the soak, and the soak goes down the drain.

Step 4: Pack, fill and process

1. Pack the whole peppers into a hot jar to within 2 cm (¾ inch) of the top. That is the solids level, not the headspace.
2. Add hot brine to cover the peppers to within 1 cm (½ inch) of the top. That 1 cm is the headspace.
3. Remove air bubbles with a nonmetallic utensil and adjust the headspace by adding more peppers and brine if needed.
4. Wipe the rim, centre a hot sealing disc, and screw the band down until resistance is met, then to fingertip tight.
5. Check the water covers the jars by at least 2.5 cm. Cover the canner and bring it to a full rolling boil before you start timing.
6. Process 10 minutes at altitudes up to 1000 ft (305 m), in 500 mL jars. Bernardin publishes no 1 L time for this recipe — do not size up.
7. Adjust for altitude per our Canadian altitude-adjustments guide — required above 305 m.
8. Remove the canner lid, wait 5 minutes, then lift the jars out without tilting. Cool upright and undisturbed 24 hours, then check the seals. Do not retighten the bands.

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

Ring-cut peppers: refrigerator only

Bernardin states the rule themselves, in the headnote to their Seasoned Tomato Sauce — a tested recipe is safe because its acidity and its processing time were established together:

“Even though onions are added to this tomato sauce, it can still be processed safely in a boiling water canner. This is because its acidity and a safe processing time have been scientifically determined. Do not alter ingredients as this may result in an unsafe product.”

That sentence is about a tomato sauce, not about peppers — but the rule it states is general, and it is why everything below belongs in the refrigerator rather than on the shelf.

Sliced rings are what most people picture, and they are what this page used to describe. They are not the pack Bernardin tested. The 10 minutes above was tested on whole peppers with two slits in them; slicing changes how heat moves through a packed jar, so that time does not carry over. We will not publish a processing time for a pack nobody has tested.

You can still make them — just not for the shelf. This is our variation, not Bernardin’s:

1. Slice the peppers into 1 cm rings. No soak needed for this version.
2. Pack into clean jars with a garlic clove and ½ tsp mustard seeds if you like.
3. Bring the same brine to a boil and pour it over, covering the rings completely.
4. Cool, lid, and refrigerate.
5. Use within about 2–3 months. This window is ours, not a specification — no authority we could find publishes a keeping time for a home-made refrigerator pickle. Past the window, Québec’s rule is the one to follow: “When in doubt, throw it out!” A normal smell and a normal look are not evidence that a jar is still good — they only ever condemn, never clear.

Never store these at room temperature, and never treat them as shelf-stable. They are a fridge pickle. If you want jars for the pantry, do the whole-pepper recipe above.

Wait 2 weeks before eating

Freshly canned banana peppers taste raw and sharp. Give them time:

• Week 1: brine still harsh, peppers taste under-pickled
• Week 2: properly pickled — good to open
• Week 4+: peak flavour, mellow and balanced

Storage

• Store in a cool, dark, dry place at room temperature. Remove the screw bands; wipe and dry the bands and jars before storing.
• Best quality 12 months sealed. — Bernardin’s guidance is to use home-canned food within one year. That is a quality window, not an expiry: the jar is as safe as the process made it. Colour, flavour and texture fade.
• After opening, refrigerate and use within one week — HealthLink BC’s published guidance for any opened home-canned container.
• Inspect before opening — fading colour is normal; an off smell, fizzing, or fuzzy mould means discard without tasting.

Sweet, hot, or mixed

Bernardin’s recipe covers all of these in one method — same soak, same brine, same time:

• Sweet banana peppers — the classic mild sandwich pepper. Pale yellow, tangy, no heat.
• Hot banana peppers (Hungarian hot wax) — jalapeño-level heat, same method. Label the jars clearly.
• Jalapeños as an accent — Bernardin’s own headnote: omit them for mild pickled peppers, increase the number per jar for hotter ones.
• Sweet green, red or orange peppers, and Italian peppers — also named in the same recipe.

How to use pickled banana peppers

• Submarine and deli sandwiches — the canonical use
• Pizza — scattered on top before or after baking
• Greek and antipasto salads
• Burgers and hot dogs
• Cream cheese dip — chopped and folded in
• Straight from the jar as a snack

Common problems

• Peppers went soft. Usually a skipped or shortened soak, or limp peppers to start. Give them the full 12–18 hours and use fresh, firm fruit. Never reduce the vinegar to compensate.
• Brine turned cloudy. Often just hard water or the horseradish — harmless. Cloudy with an off smell means spoilage; discard without tasting.
• Peppers lost their bright colour. Normal. Vinegar mutes the yellow over time. Cosmetic only.
• Too sour for your taste. Balance it with sugar, never by cutting the vinegar. The 5:1 ratio is the safety figure in this recipe.
• A jar didn’t seal. The 24-hour rule.

Yield expectations

• 1 × 4 qt (4 L) basket → about 8 × 500 mL jars, which is Bernardin’s stated yield.
• Budget two days, not one: the soak runs 12–18 hours before you start.
