  • Slice the onions and pack into a glass mason jar. I used a tall 750ml jar (which is about 25oz for my US friends, or you can divide them between two smaller jars). I used a Vitamix tamper to pack it down, but a spoon works too.
  • Add the rest of the ingredients into a saucepan and bring to a boil. Once the sugar and salt are dissolved, remove from heat and slowly pour into the jar.
  • You'll have some liquid left over, tamper the onions in a little further and add a little more of the brine.
  • Let cool to room temperature (about 30-40 minutes), put a lid on it and serve.


This keeps in the fridge for about a week. Add it to your salads, tacos, burgers, sandwiches, and stir fries!

Container Counts

The full recipe is just 2 greens. So depending on how much you use in your salads, burger toppings, etc is how much it would count for in a serving.
