About my homemade Quick picked red onions recipe
As always my recipes are super easy and takes only 5 minutes to make! I know you will also love my pickled jalapenos recipe too.
Once you mix everything together, the onions rest in the jar for an hour or more, soaking up all the delicious flavours. I recommend giving them at least an hour before serving to get the best taste. And the good news is that you can store them in mason jars or any airtight container in the fridge for up to a month!
I love serving these pickled onions with my vegan chickpea tikka masala and homemade naan - they make such a terrific combo! But, they're also amazing on my vegan Buddha bowls. Trust me, you'll love them!
Ingredients for pickling Red Onion

If you're looking for an easy and flavourful way to add some zing to your dishes, pickled red onions are a great option. And the best part is, all the ingredients needed are likely already in your pantry!
- Onions: I prefer Red onions, but you can also use white onions or a combination of both.
- Vinegar:Apple cider vinegar adds a subtle sweetness. Alternatively you can also use white vinegar, white wine vinegar or distilled vinegar. The acidity helps to preserve the onions.
- Salt: Essential in pickling as it draws out moisture and intensifies flavor.
- Maple syrup, Honey or sugar: Either of them works as a sweetener in the recipe and balances the acidity. Adjust the amount based on preference. I prefer to use Maple syrup over honey, as its naturally vegan and always available in my fridge.
- Hot water: Preferred over warm water to speed up the pickling process and help dissolve the salt and sugar. Just use boiling hot water from the kettle.
Variations
Feel free to add garlic cloves, red pepper flakes, black pepper corn, mustard seeds or fresh herbs like dill, thyme or organo to the brine for added flavours.
