It’s been difficult to get myself interested in canning this season. Last summer I was much more zealous, with recipes like my Golden Apricot Jam and Last Harvest Garden Salsa.

Small Batch Canned Pickled Red Onions
This quick and easy canning recipe is a perfect way to add some zing to everything from salads to sandwiches!
Ingredients
- 2 large red onions, thinly sliced
- 1 C apple cider vinegar
- 2/3 C organic cane sugar
- 1 Tbsp pickling salt
- 8 peppercorns
- 8 allspice berries
- 4 thyme sprigs
Instructions
- Before beginning a canning project, it's important make sure that you have a clean work space and that you have everything set up and ready to go. Place your jars in your dishwasher on the high heat setting, without soap, in order to sterilize them. If you don't have a dishwasher, you can sterilize them by placing them in a large pot of boiling water for 5 minutes.
- Fill a large pot ¾ of the way full with water and begin to bring to a boil over high heat. This will be your hot water bath for canning your onions.
- Cut onions into 1/4 inch slices.
- Dissolve the vinegar, sugar and salt in a saucepan and bring to a simmer.
- Add the onions to the saucepan and simmer on low for 5 minutes uncovered. In the last minute, add the thyme.
- Sterilize a pair of tongs by dipping the ends in boiling water for a minute. Use them to pack the onions and one sprig of thyme each into two 12 oz sterilized canning jars. Add 4 peppercorns and 4 allspice berries into each jar.
- Using a ladle, fill the space around the onions with the pickling juice, leaving 1/2 inch of head space.
- Place your canning lids and rings into a small saucepan with water and bring the water up to scalding temperature (just before boiling) in order to sterilize them. Don't boil, as this may damage your seals. Dip a clean paper towel in the boiling water of your large pot and use it to wipe the rims of your jars. Using a canning lid magnet, grab the lids and place them on your jars. Screw the rings onto your jars until you first meet resistance and then unscrew them a millimeter or two. This is important for creating a seal.
- Process for 10 minutes submerged in a boiling water bath. After removing the jars from the water, allow them to sit undisturbed for 24 hours before handling. Store in a cool, dry, dark place for up to 1 year with the rings removed. Once opened, store in the refrigerator for up to a month.
Notes
If you decide not to can this recipe, the onions have a refrigerator shelf life of 2 weeks if not processed in a hot water bath canner. Allow them to pickle for at least 1 hour before using.
Double or triple the recipe as desired to can larger batches.

You don’t have to convince me – I love the idea of pickled red onions. In fact, I’ve just finished making small batch spicy sweet pickles using Kirby cucumbers and they are my new favorite condiment. Would love to try these.
Mmmm… I love Kirby cucumbers. They have an extra crispness to them. I’m 6 months pregnant at the moment, and not to be cliche, but your pickles sound amazing! I would totally trade you a jar for a jar!
I can’t wait to try this! I’ve made pickled red onions for the refrigerator before, but I wanted a recipe specifically for canning – I just got into doing it this year and I’m loving how much easier it is than I ever thought it would be. Thank you for sharing this!
I love canning! Not to mention having all kinds of tasty condiments on hand! When it comes to pickled red onions I like both the refrigerator and the canned versions. Because of the method of heating the onions to preserve them I think that you’ll find this recipe has an entirely different flavor and that it’s much sweeter.
This recipe is really good and tasty, but the pre-cooking of the onions is one part I can’t quite wrap my head around. I have never cooked any veggies before canning them. My thought was always that the pre-cooking occurs while the canning liquid and raw onions are immersed in the canning bath. Seems redundant. Is there a reason why you prefer to include this step?
Hey scott! Pre cooking the onions candies them a little bit. For this particular recipe it was purposeful.
Precooking the onions also makes it easier to fit the onions in the smaller canning jars without having to break them up…well, at least for me it did.
Do the onions get mushy at all after some time?
What is the approximate poundage for 2 large onions? This sounds delicous. Thanks!
Hey Rachel,
When you say a “sprig of thyme”, how big is that? Two inches, or is a 6 inch spring better?
You have several recipes I am going to try, but this pickled red onion I want to try right away1
Thank you and hope you feel great throughout your pregnancy!
