It will last months in your fridge in a tight fitting jar- making it a perfect way to preserve red onions in the tastiest of ways.
If it’s summer and you like to eat seasonally, stock up and make a big batch of this.

Pickled Red Onions is a very basic recipe that you can make with what you have in your pantry right now.
Yet, it is primed for your personalization and customization.

Making these onions is very simple, simply boil water, pour over your sliced onions, let sit, drain, then put it in your brine, jar it up- Bam!
That’s it!

The customization you can do with this is endless, you could add in cloves of garlic, chunks of ginger, slices of red pepper, swap out the type of vinegar, swap the type of sweetener, or play with different spices.

Here are a few ideas for you to customize your pickled red onions

  • Asian inspired with rice vinegar, chunks of ginger, red pepper flakes/ powder, and lemon grass (or try adding a tsp of red thai curry paste), then sweetened with 50/50 mirin and sugar
  • Meditarian inspired with balsamic vinegar, cloves of garlic, and red pepper
  • Herb infused with rosemary and thyme
  • Sweet apple with apple cider vinegar and vegan apple honey
  • Make it smokey with a little smoked salt, smoked paprika, or a few drops of liquid smoke
  • Make it spicy with a tsp of sriacha, gochujang, red pepper flakes/powder, fresh chilis, or fresh jalapenos
  • Try other sweeteners like dark maple syrup, brown sugar, coconut sugar, date sugar, apple honey, dandelion honey, agave, xylitol

Just because there are endless ways to customize it to your personal preference don’t be afraid to try the basic recipe!
This basic recipe is extremely versatile for topping burgers, salads, burritos, or as a side to your characterize board.
Over flavoring them with your customization could potentially limit you on how you can use these onions.
Consider this, if you make a huge batch of these pickled onions and add red thai curry paste, ginger, and garlic- you might not want to use that to top your bbq burger or in your southwest style burrito. (But imagine how amazing it would be paired with kimchi!!!)

What I love about this recipe is that you can easy reuse your brine to make tasty, quick, and healthy salad dressings.

When I make my basic pickled onion recipe I’ll make it into a dressing by adding some toasted sesame oil, coconut amnions, garlic powder, and sriracha-
creating a sweet, spicy, nutty, yet tangy dressing perfect for my Buddha Bowls or Salads.

Do not skip the step on letting your onions soak in boiled water- this helps remove that raw onion bite, creating a sweeter overall flavor.

Do not replace red onions for white or yellow onions, even when you soak them in boiling water, they do not loose that sharp bite.
