You can pressure can celery to preserve it for months or even years as long as you follow safe canning guidelines.
Celery is a low-acid vegetable, so it has to be pressure canned instead of water bath canned to kill harmful bacteria like botulism spores.
If you’ve been wondering how to pressure can celery, the process is pretty straightforward once you get the hang of it.
You’ll need fresh celery, clean jars, a reliable pressure canner, and a bit of patience.
In this post, we’ll walk through why pressure canning celery works, how to do it step by step, and a few tips to keep your canned celery safe and tasty.
Let’s dive in.
Why You Should Pressure Can Celery
Celery is a low-acid vegetable with a pH above 4.6, which means boiling water alone won’t make it safe for long-term storage.
That’s why pressure canning celery is the only recommended method for preserving it at home.
Here’s why it works so well:
1. It Eliminates Harmful Bacteria
Pressure canning celery reaches temperatures of 240°F to 250°F, which is hot enough to destroy botulism spores and other dangerous pathogens.
Water bath canning only reaches 212°F, so it can’t kill those spores in low-acid foods like celery.
That’s the main reason you must pressure can celery instead of using a water bath.
2. It Preserves Texture and Flavor
When you pressure can celery properly, it keeps a decent crunch and that fresh, mild flavor you love.
Overcooking can make it mushy, but following the right time and pressure settings helps you avoid that.
Home-canned celery tastes way better than store-bought canned versions because you control the quality.
3. It Saves You Money and Reduces Waste
If you grow celery or buy it in bulk, pressure canning celery lets you stock up without worrying about spoilage.
A big bunch of celery that would normally go limp in your fridge can last for over a year in jars.
That’s a huge win for your budget and your meal prep routine.
4. It’s Great for Soups, Stews, and Stocks
Having jars of pressure canned celery on your shelf means you’re always ready to add instant flavor to soups, stews, and stocks.
You can also use it in casseroles, pot pies, or even as a quick side dish.
The convenience alone makes learning how to pressure can celery totally worth it.
How to Pressure Can Celery Step by Step
Now let’s get into the actual process of how to pressure can celery at home.
Follow these steps carefully to keep everything safe and delicious:
1. Gather Your Equipment and Ingredients
You’ll need a pressure canner (not a pressure cooker), mason jars, lids, rings, a jar lifter, and a clean towel.
For the celery, choose fresh, crisp stalks that are free of blemishes.
You’ll also need salt (optional), boiling water, and a bit of lemon juice if you want to brighten the flavor.
2. Prep the Celery
Wash the celery thoroughly under cold running water to remove dirt and grit.
Trim the leaves and tough ends, then cut the stalks into pieces that fit your jars, usually about 1 to 2 inches long.
You can also dice the celery if you prefer smaller chunks for soups and stews.
3. Prepare Your Jars and Lids
Wash your jars in hot, soapy water and keep them hot until you’re ready to fill them.
Simmer the lids in hot water for a few minutes to soften the rubber seal.
Never use damaged jars or rusty lids because they won’t seal properly.
4. Pack the Jars with Celery
Fill each hot jar with the cut celery, leaving about 1 inch of headspace at the top.
You can add 1/2 teaspoon of salt per pint or 1 teaspoon per quart if you like.
Then pour boiling water over the celery, making sure it covers the pieces and still leaves that 1-inch headspace.
5. Remove Air Bubbles and Wipe the Rims
Use a plastic spatula or bubble remover to slide around the inside of the jar and release trapped air.
Wipe the jar rims with a clean, damp cloth to ensure a good seal.
Place the lids and rings on, tightening them fingertip-tight only.
6. Load the Pressure Canner
Put 2 to 3 inches of hot water in the bottom of your pressure canner.
Place the jars on the rack, making sure they don’t touch each other or the sides of the canner.
Lock the lid and turn the heat to high.
7. Vent and Pressurize
Let steam escape from the vent for a full 10 minutes before you put the weighted gauge or dial gauge on.
Then bring the pressure up to 10 pounds (for dial gauges) or 11 pounds (for weighted gauges) if you’re below 1,000 feet elevation.
Adjust for altitude if you’re higher up.
8. Process for the Right Time
Once you reach the correct pressure, start your timer.
Process pint jars of pressure canned celery for 30 minutes and quart jars for 35 minutes.
Keep the pressure steady the whole time and never let it drop.
9. Cool, Check Seals, and Store
Turn off the heat and let the pressure drop to zero naturally.
Wait 10 more minutes, then open the lid and remove the jars with a jar lifter.
Let them cool for 12 to 24 hours, then press the center of each lid to check the seal.
If the lid doesn’t pop, you’ve successfully pressure canned celery.
Tips for Perfectly Pressure Canned Celery
Here are a few extra pointers to help you master how to pressure can celery:
1. Use Fresh, Crisp Celery
Old, limp celery won’t give you great results, so start with the freshest stalks you can find.
2. Don’t Overpack the Jars
Leave that 1-inch headspace so the liquid can expand without forcing the lids off.
3. Adjust for Altitude
If you live above 1,000 feet, you’ll need to increase the pressure or processing time based on official canning guidelines.
4. Always Acidify if You’re Unsure
Some people add a tablespoon of lemon juice per pint just for extra safety, though it’s not required for pressure canning celery.
So, How Do You Pressure Can Celery?
You pressure can celery by packing fresh cut stalks into hot jars, covering them with boiling water, and processing them in a pressure canner at 10 to 11 pounds of pressure for 30 to 35 minutes.
That’s the simple answer to how to pressure can celery.
It’s a safe, effective way to keep celery on your shelf for a year or more.
And once you get comfortable with the process, you’ll wonder why you didn’t start pressure canning celery sooner.
Give it a try, and enjoy the convenience of home-canned celery whenever you need it.
