Fermented Onions

A delicious and flavourful fermented onion recipe.


  • 1 Litre Glass Jar


  • 2 Large onions (Any colour)
  • 1 litre Water (No chlorine)
  • Salt


  • Peel and cut the onions into strips (julienne cut).
  • Add 30 grams of salt to the litre of water (3% brine).
  • Put the onion that has been cut into julienne strips in the jar.
  • Cover the jar with brine. It is important that the liquid from the brine completely covers the onions.
  • Cut a round piece of a big onion and put it on the top, to make some kind of lid. The weight will help the onions stay at the bottom of the jar.
  • Let the onions ferment for 3-7 days, in a place where they are not in direct sunlight. Make a note of the date when you started fermenting them.
  • After 3-4 days, you can taste them and if they are to your liking, you can put them in the fridge.
