Yes, you can pressure can celery, but it has to be done the right way.
Celery is a low-acid vegetable, so it can’t just be tossed into a water bath canner and left on the shelf.
It needs the high heat of a pressure canner to be safely preserved.
So if you’ve been wondering if you can pressure can celery at home, the answer is absolutely yes, and it’s a great way to keep this crunchy staple on hand.
In this post, we’ll look at why you can pressure can celery, how to do it safely, and a few tips so your jars turn out perfect every time.
Let’s get into it.
Why You Can Pressure Can Celery
You can pressure can celery because it’s a low-acid food that needs a pressure canner to reach safe temperatures.
Here’s why that matters.
1. Celery Is a Low-Acid Vegetable
Celery has a pH level that puts it firmly in the low-acid category.
That means harmful bacteria like Clostridium botulinum can survive in it if it’s not processed correctly.
A boiling water bath simply can’t get hot enough to kill those spores.
Only a pressure canner can reach the 240°F needed to make celery safe for long-term storage.
That’s the main reason you can pressure can celery but not water bath can it.
2. Pressure Canning Reaches the Right Temperature
A pressure canner builds up steam and pressure inside the pot.
This raises the boiling point of water way above what you get in a normal pot.
At 10 pounds of pressure, the temperature inside hits 240°F.
That’s hot enough to destroy botulism spores and other dangerous pathogens.
So when you pressure can celery, you’re not just cooking it, you’re making it shelf-stable and safe.
3. Celery Holds Up Well When Canned
Some vegetables turn to mush when canned, but celery actually does fine.
It keeps a bit of its crunch if you don’t overcook it, and it’s great for soups, stews, and casseroles later.
You can pressure can celery on its own or mix it with other veggies like carrots and onions.
Either way, it’s a handy ingredient to have in your pantry.
How to Pressure Can Celery Safely
If you want to pressure can celery at home, follow these steps so you don’t run into trouble.
1. Start With Fresh, Crisp Celery
Pick celery that’s firm and bright green, not limp or brown.
Wash it well and cut off the leaves and the base.
Then chop it into pieces that fit your jars, usually about one-inch chunks or slices.
You can leave them a bit larger if you plan to use them in soups later.
2. Pack the Jars and Add Hot Water
Fill clean, hot jars with your chopped celery, leaving about an inch of headspace.
Then pour boiling water over the celery, still keeping that one-inch headspace.
You can add a pinch of salt if you like, but it’s optional.
Wipe the rims, put on the lids, and tighten the bands fingertip-tight.
3. Process in a Pressure Canner
Put the jars in your pressure canner with the right amount of water according to your manual.
Seal the canner and let it vent steam for 10 minutes before you put the weight on.
Then bring it up to pressure, usually 10 pounds for a dial gauge or 15 for a weighted gauge, depending on your altitude.
For pint jars of celery, process for about 30 minutes.
For quarts, go with 35 minutes.
Always check your canner’s manual or the latest USDA guidelines for exact times.
4. Let the Canner Cool Down Naturally
Once the time is up, turn off the heat and let the pressure drop on its own.
Don’t rush it by running cold water over the canner.
That can cause the jars to crack or the liquid to boil out.
When the pressure is back to zero, open the lid and let the jars sit for a few minutes.
Then take them out and let them cool on a towel.
Common Mistakes to Avoid When You Pressure Can Celery
Even though you can pressure can celery, a few missteps can ruin your batch or make it unsafe.
1. Skipping the Pressure Canner
Never try to water bath can celery.
It’s not safe because the temperature doesn’t get high enough to kill botulism spores.
If you see a recipe that says you can water bath can celery, ignore it.
Always use a pressure canner.
2. Overcooking the Celery
If you process it too long, celery turns to mush.
Stick to the recommended times and don’t guess.
Also, use fresh celery, not old limp stalks, because they’ll fall apart even faster.
3. Not Adjusting for Altitude
If you live above 1,000 feet, you need to increase the pressure.
At higher altitudes, water boils at a lower temperature, so you need more pressure to reach 240°F.
Check your altitude and follow a trusted chart so your celery is safe to eat.
So, Can You Pressure Can Celery?
Yes, you can pressure can celery, and it’s a smart way to preserve this crunchy veggie for months.
Just remember it’s a low-acid food, so a pressure canner is a must.
Follow the right steps, use fresh celery, and adjust for your altitude.
That way you can pressure can celery safely and enjoy it in soups, stews, and more all year long.
Now you know you can pressure can celery and how to do it right.
