Canning AsparagusOne of my favorite things about spring is watching the tops of the asparagus poke up through the soil. Because I know that means that I’m not too far away from eating that asparagus that is poking up through the soil. Grilled asparagus, bacon wrapped asparagus, asparagus with Hollandaise sauce, Steamed Asparagus with Balsamic Vinaigrette, pickled asparagus…the list could go on for days.

And while I prefer to eat my asparagus fresh in the spring, it’s nice to have some available for other times of the year. We typically serve it canned at Thanksgiving and Christmas as a special treat and at other times when cravings hit, so I don’t can huge amounts of asparagus like I do, say, tomatoes for instance. 🙂 So today, I thought I’d teach you how to can asparagus.

Canning Asparagus|How to Can Asparagus

For canning asparagus, you need to have about 2-ish pounds per pint jar. You can either buy it all at once from your local farmers’ market, or you can harvest your own as you get it. Fresh asparagus from your garden will keep for 10-14 days in the fridge if you put it upright in a glass of water. If you get it at the store it will last about 5-7 days.

Because we like the tall spears, I use 1 ½ pint jars so I don’t have to cut so much off of the ends. 1 ½ pints are the same size around as the pint jars, they’re just taller. So they use the same amount poundage wise as the pints.

If you are new to canning, or need a refresher, you can learn all about canning here.

Here’s What You Need for Canning Asparagus

Fresh asparagus spears
Canning jars (pints, 1 ½ pints, or quarts)
New lids (If you are using the Tattler reusable lids, make sure you follow the directions that came with them.)
Rings
Boiling water
Sea salt (optional)

To prepare the asparagus, wash them in a sink of cold water by swishing them back and forth. Now, bend the spears near the bottom until they snap in two. This separates the “woody” part of the stem from the tender part. Don’t throw those ends out, though. Toss them in the freezer for later.

hold the ends and bend

it’s a snap!

You need to measure the height of the jars you will be using. You need a 1 inch headspace, so your spears need to be an inch shorter than the jars. So put the spears on a cutting board and measure them. Cut the stem off so they are the correct length. You can add those pieces to the ends you snapped off in the step above. Use them later to make Creamy Asparagus Soup.

measure twice, cut once

You can raw pack or hot pack your asparagus spears. I prefer the raw pack method for canning asparagus.

Here’s how you raw pack asparagus

Before you begin, make sure your jars are clean and hot, and your lids are prepared according to the manufacturer’s directions.

Pack the spears into the clean, hot jars as tightly as you can. The spears will shrink up dramatically, so really pack ‘em in there. If you are canning asparagus pieces pack them as tightly as you can leaving 1 inch of headspace.

it’s easier to pack it in the jar when it’s sideways

Now fill the jar with boiling water, again leaving 1 inch of headspace. Add salt if desired, using ½ tsp for pints and 1 ½ pints, and 1 tsp for quarts.

fill with boiling water

Wipe the rim with a clean, dry cloth. Now seat the lid and put on the ring, tightening just until finger tight. Fill and close the remaining jars. Place the jars in the canner, adding the amount of hot water appropriate for your canner.

in the canner they go!

Secure the canner lid, turn on the heat, and vent for the amount of time specified for your canner. Place the weight on the vent and bring up to pressure. If you are using a dial gauge canner, process at 11 pounds pressure for 30 minutes for pints; 40 minutes for 1 ½ pints and quarts. If you are using a weighted gauge canner, use the 10 pound weight and process for the same length of time. Don’t forget to adjust for your altitude if necessary.

After processing allow the canner to cool down. Remove the jars and put them on towels in a draft free location to cool. After a minimum of 12 hours, check the seals, make a cool label with the contents and the date, and put them in your pantry. Now stand back and admire your handiwork!

all sealed and ready to go on the shelf!

Blessings!

    • Sharon, unfortunately, it does make them mushy. I don’t think it’s as bad as the stuff you can buy at the store, but it’s possible that I’m biased. 🙂

  1. The first time I had asparagus was when I was in the Army, I’m not really a picky eater and am open to trying just about any food as long as it looks interesting, smells good and if it tastes good to me, with only a few things I’ve tried in my 64 years that I don’t like asparagus was one at that point, it tasted nasty and smelt bad, here to find out they cooked it to death and it sat for a long time a big no-no for asparagus, for years I wouldn’t even think of eating asparagus until a friend and I were camping and came across some wild asparagus, he talked me into trying it again but first raw, to my surprise there was a nutty beautiful flavor I had to have more of, we had our dinner that night in the woods made up of wild foraged edibles and I couldn’t get enough even after it was cooked, my friend being a professional chief at the time explained that over cooking turns asparagus into something terrible and I agree that is why I only eat it fresh and why I think I will not try to can it and why I only buy fresh, my wife and I do a lot of canning but I cannot convince her to try asparagus since she had a similar experience and is a very picky eater.

    • I have never seen it growing wild! That’s pretty cool. My favorite way to eat it is actually grilled, but still crisp. 🙂 But I totally understand not liking it canned. Thanks for your comment!

    • Sarah, I put it in a small saucepan with the liquid from the jar and just heat it up. It’s already been cooked through the canning process, so heating is all that’s necessary. 🙂 Thanks for stopping by!
