If you enjoy asparagus, canning it is an easy way to have it all year round. In this article, I’ll show you how to do it with easy to follow instructions.
You’ll be surprised just how easy it is, and it’s a great way to use up your crop from the garden, or stock up from the farmer’s market or grocery store.
Canned asparagus is delicious right out of the jar, or as a quick heat-and-serve side dish. It’s also great in recipes like soups, stews, and omelets.
Below, I’ll show you everything you need to know about how to can asparagus, including some useful tips for the best success.
Best Types Of Asparagus For Canning
Some of the best asparagus varieties to use for canning are Jersey Giant, Jersey Knight, and Purple Passion, but you really could use any kind.
Just make sure it’s as fresh as possible, straight out of the garden is best. The crisper it is, the better the texture will be after canning.
Preparing Asparagus For Canning
To prepare your asparagus for canning, first give it a quick rinse to remove any dirt or debris.
Then, trim off the hard end of the stems and cut the spears into about 4-6 inch pieces, or to the length that fits best in the size of the jars you use.
Be sure to wash and sterilize your jars and keep them hot and ready until it’s time to fill them.
Methods For Canning Asparagus
There are two ways you can pack asparagus into your jars for canning: either hot or raw.
The one you choose depends on the amount of time you have and your personal preference. Try both methods to see which one works best for you.
Hot packing means that you place the spears in boiling water for 2-5 minutes, and then put them into the jar right after.
This can help preserve the quality of your canned asparagus while it’s stored, but it does add more time to the process.
Raw packing is the simplest and quickest option because all you do is place the spears into the jars, then add the hot water or brine.
The downside is that the asparagus tends to float when you pour liquid into the jar, which can be frustrating. The workaround is to pack the spears tightly to prevent them from floating.

Pressure Canning Asparagus
Because it is a low-acid vegetable, the only safe way to can asparagus at home is by using a pressure canner.
The high heat is essential to kill all of the potentially harmful bacteria, and this cannot be achieved in a hot water bath.

How To Store Canned Asparagus
It is important to store your canned asparagus in a cool, dry, and dark place such as your pantry or kitchen cabinet.
Before storing it, remove the bands and make sure that all of the lids have a tight seal. Check them by pressing on the center of the lid to ensure they don’t move.
If you have any that didn’t seal, put them in the fridge and consume them within 3 to 4 days.
How Long Does Canned Asparagus Last?
When stored properly, canned asparagus will last for about 3 to 5 years. Always check that each one still has a tight seal before eating it.
Below are my answers to some of the most common questions I get asked about canning asparagus.
Do you need to blanch asparagus before canning?
No, you do not need to blanch asparagus before canning it, especially in plain water. If you want to use a brine, then it is often nice to blanch it first as it softens the spears slightly to better absorb the flavors from the brine.
Can you can asparagus without pickling it?
Yes, you can can asparagus without pickling it, as long as you use a pressure canner.
Is home canned asparagus mushy?
Home canned asparagus is not mushy as long as you process it correctly, though it will be softer than it is when it’s raw. If yours is mushy it’s usually a result of overcooking.
Does asparagus need to be pressure canned?
Yes, asparagus does need to be pressure canned because it’s a low-acid food. This is the only safe method to use at home, as a boiling water bath can’t get hot enough.
Can asparagus be water bath canned?
No, asparagus cannot be water bath canned, as it is not naturally acidic. A boiling water bath will not get it hot enough to kill all of the harmful bacteria.
