How to Make Pickled Red Onions

Only 5 basic ingredients needed; red onions, white vinegar, water, sugar, and sea salt.

The onions will be ready to eat once they’ve turned bright pink and become tender. This could take anywhere from one hour to overnight, depending on the thickness of your onions.


  • 2 red onions, thinly sliced
  • 2 cups apple cider vinegar or white vinegar
  • 2 cups water
  • 2-3 tbsp raw sugar (I used coconut sugar)
  • 2 tbsp sea salt

To make:

  1. Slice the red onions as thin as you can. Using a mandolin is helpful.
  2. Fill jars with sliced red onions.
  3. In a medium saucepan over low-medium heat, combine the vinegar, salt, sugar, and water and stir until sugar dissolves. Let cool and pour over the onions, making sure they’re fully immersed in the liquid. Set aside to cool and ferment. Once done, cover and store in the fridge for up to 3 weeks.
