Ingredients

  • 2
    medium red onions, thinly sliced
  • 1 cup (240 mL)
    boiling water

    white vinegar
  • ¼ cup (60 mL)
  • 2 tsp (10 mL)
  • 1 tsp (6 g)
    coarse sea salt

Directions

  1. Add the sliced onions to a large heat-proof jar*.
  2. Next, pour in the water, vinegars, agave, and salt. Seal the jar tightly and give it a few gentle shakes. Transfer to the fridge.
  3. It's best to leave the onions to pickle overnight, but they're still very tasty after just 1 - 2 hours. Enjoy on your favourite sandwiches, salads, or nourish bowls!

Notes

  • * If using 2 medium onions, a 32 oz (1 litre) mason jar should be the correct size. If using more or fewer onions, scale the size of the jar up or down accordingly.

Storage

  • Keep the sealed jar in the fridge for up to 2 - 3 weeks.

This is a very tasty and simple recipe. Other recipes I have found call for much larger quantities of vinegar, sugar and salt and it seems like such an unnecessary waste to me! Because of this I hadn’t found a recipe for pickled onions that I felt compelled to make more than once, until now! This will be my go to from now on! Thanks!

PUL Team - March 29, 2022, 8:50 p.m.

Aw we're so happy to hear, April, it means so much!

I read this recipe and said What? Just a gift that keeps on giving!!!! Thank you so much!!! A check off my list of new ingredients to try!!!

PUL Team - Feb. 14, 2022, 3:06 a.m.

We hope you enjoy it, Pamela!

Hi, thank you for this recipe! Is it possible to use cooled down boiled water (~60C) instead of 100C boiling water? I've had my jars breaking before when using boiling water :/
Thank you!

PUL Team - Feb. 6, 2022, 9:35 p.m.

Hey Clem! The hot water helps to blanch the onions. We suspect that slightly cooled boiling water will work fine, although wouldn't recommend allowing it to cool too much, such as below 50°C (122°F) if possible. Some jars are heat-proof as well which may help in case you're interested. We hope this helps for now 😃

Clem - Feb. 7, 2022, 11:42 a.m.

Thanks for the reply! I ended up mixing everything in a clean saucepan, and transferring to the jar a few minutes later, when the water had cooled down a little bit. I hope this works as well :) Looking forward to taste them tonight!

Thank you Sadia for the great recipes. I got inspired to eat vegan food!!
Can we use the same recipe for Pickled cabbage and beetroots.

PUL Team - Jan. 31, 2022, 8:10 p.m.

Aw thanks for the kind words, Monica! Yes, you can use other vegetables instead of onion if desired. We've tried cabbage, carrots, and cucumber with success 😃


Ashwini - Jan. 6, 2022, 11:54 p.m.

Hi Sadia,

Thanks for all the recipes, so much love for creating this wealth of information, it has really helped me improve my relation with food by enjoying what I cook and even just cooking.

Can I reuse any leftover pickled juice (without onions) after a month for another batch or do you advise throwing it away?

PUL Team - Jan. 7, 2022, 5:27 a.m.

Hi Ashwini, thanks for taking the time to share the very kind words! It means so much. We'd recommend using fresh brine each time for optimal food safety and flavour. The onions will absorb the vinegar and salt from the brine so if reused, the juice won't be as effective. We hope this helps for now✨

You are awesome, i really enjoy watching your videos. Lots of love , “watandar”😁

PUL Team - Jan. 4, 2022, 5:01 p.m.

Awe thank you, Najia!


Mutant_Lola - Dec. 24, 2021, 12:31 p.m.

Easy recipe and very useful for a single household, because its difficult to finish up the onions (for me at least). The pickled onions is a nice topping ready at hand. Thank you

PUL Team - Dec. 25, 2021, 5:41 p.m.

So happy to hear, Mutant_Lola, thank you for the review!

Hi
can agave be substituted for something else?

PUL Team - Dec. 24, 2021, 5:21 a.m.

Hi vt, a lovely question 🙂 The agave can be substituted with sugar or another syrup if desired. We hope you enjoy the recipe if you're able to give it a try!

I've learned that white vinegar was not healthy at all. Is it ok to use just apple vinegar? Thanks for your racepies, they always give me a piece of inspiration :)

PUL Team - Dec. 24, 2021, 5:15 a.m.

Hi there, I.B, thanks for the question. We personally enjoy the flavour that the combination of vinegar creates. Feel free to use all apple cider vinegar if desired though. The end result may be a tad sweeter but should still be delicious 🙂
