  • 1 medium-large red onion
  • 6 tbsp apple cider vinegar
  • 6 tbsp white vinegar
  • 3/4 cup water
  • 1/2 tsp whole cumin seeds
  • 1/2 tsp whole coriander seeds
  • 1/4 tsp hot pepper flakes, optional
  • 1 tsp sea salt
  • 2 tbsp sugar, brown or white, or honey


  • Thinly slice onions using a mandoline or sharp chef's knife
  • Pack into a jar or other glass container with a lid
  • Add cumin and coriander seeds and hot pepper flakes if using.
  • Place vinegars, water, salt and sugar in a pot and bring to a boil. Turn down the heat and simmer for one minute or until salt and sugar are dissolved.
  • Pour over onions and spices, press down onions so they are submerged in the pickling solution. Let sit, with lid off, until cooled.
  • Cover and refrigerate. Pickled onions will last in the fridge for 3-4 weeks.


Pickled onions are ready to eat after 30 minutes of being in the pickling liquid and will last in the fridge up to a month.
When you are done a jar of pickled onions, reuse the pickling liquid by placing more sliced onions in and letting sit overnight. 
Use on salads, tacos, burgers, burrito bowls, with eggs, and pasta
