Pickled Red Onions

Pickled Red Onions - Easy Pickle Recipe with Canning Instructions

How beautiful are these? A sweet and salty vinegar brine, peppercorns and bay leaves are really all you need to turn sliced red onions into crave-worthy pickles. I’ve never been a fan of raw onions… I know, I’m sorry, it’s just one of those things… but these tender sweet-and-tart pickles are totally my speed. They’re a lovely and tasty topping for salads. I also love them on sandwiches, on burgers and sliders, in pitas and tacos, or cooked in omelets and other egg dishes. Really, you can add them to pretty much any savory dish for a pickled burst of flavor. They are super easy to make. If you process them using the boiling water canning method (instructions linked below) they’ll last in your pantry for years. As time passes the onions take on a pretty purplish-pink hue in the jar. These pickles would make a fun and unique homemade gift for the gourmand in your circle of friends. Or you can keep them all to yourself, if you’re feeling indulgent. It’s all good!

  1. i have never canned with raw veggies im new to canningwhen u can with raw you water bath after you put every thing in jar and then in boiling water for 10min thanks in advanced lol

    1. Hi Mike! No problem. You can cut the recipe in half or thirds if you like. Just pour the brine over the onions while the brine is still hot. Let the jars return to room temperature, put the lids on, and store in the refrigerator for up to two weeks. The longer they sit the more they’ll pickle. I should add those instructions to the post. Off to do that now! :)

  2. How do I proceed, if I do not want to “can” these. Just make and eat…. Which step sould I stop at? Do I need to boil? Help!

    1. Hi Yelena! Easy– just pour the brine over the onions while it is still hot. Let the jars return to room temperature, put the lids on, and store in the refrigerator for up to two weeks. The longer they sit the more they’ll pickle. :)

  3. Salsa Criolla. Quick Peruvian pickled red onions. Usually served with meat. I like them on a salad. You can make a small quantity – enough for just one person – or go big. Keep them in the fridge. Use within a week.

  4. I have made something similar in the past by just putting the red onions in a jar and covering with Italian dressing they taste great on a rueben

  5. Just made these. I’ve been on a homemade condiment kick these days and these fit right in. Also did some Romanian Pickled Peppers today. Question…. What is in the jar with the red filling? Thanks

  6. Hi Tory. Found you over a year ago and really enjoy your blog. I am so excited about these pickled onions. Going to check out how you make sauerkraut. Thanks

  7. Yum! Why does the brine need to be boiling if you use it straight away?

    Also, does the onion ferment in there at all or just soften? I love fermenting but miss the vinegar of pickles. Hoping I can combine the two somehow!

    1. Hi T’lia– the brine is boiled to dissolve the salt and sugar and to kill any bad bacteria that might be present when bottling. Vinegar pickles and fermented pickles are two separate things; vinegar generally takes the place of lactic acid fermentation, and vice versa. This is a vinegar pickle recipe, not a fermented one. However, if you like the flavor of vinegar and want to add it to a fermented pickle recipe, you can add a little pasteurized vinegar at the end of fermentation to capture the vinegar flavor without affecting the fermentation process.

  8. Hi, Tori.

    I made these at the beginning of March, and I opened the first jar today. I noticed that the brine had thickened and was kind of syrupy. Is that okay?

    I was also surprised that the onion had become very soft. Other pickles I’ve made have retained their crunch. Is this normal for these onions?

    Thank you very much. I’m a big fan of your blog.

    1. Hi Brian, thank you for writing and asking about this. I’m afraid this doesn’t seem right. Are all of the jars like this? Did you can the pickles using a sterile canning process, or did you make them as refrigerator pickles? Was there a funky smell? My only guess is that maybe this particular jar didn’t seal properly and perhaps went bad. Even after sterile canning it is important to store the jars in a cool, dark place away from direct sunlight. I’m sorry that this happened and unfortunately it’s difficult to pinpoint what may have gone wrong. If pickled properly these onions will be slightly soft, but should still retain some crunch. I would suggest opening another jar to see if it looks the same.

  9. I used the boiling-water method to can these. The seals were all good, but the other two jars were the same — syrupy brine and soft onions. No funky smell.

    I had them in a cabinet out of sunlight, and my kitchen is not that warm. I’m not sure what went wrong, so I’ve erred on the side of caution and dumped the pickles. I’ll try again, but this time I won’t be watching the Academy Awards when I do.

    Thanks for your help.

    -Brian
