Ingredients

Units Scale

Optional additions:

  • garlic cloves, cut in half
  • Bay leaves
  • Fresh or dried herbs (oregano, cilantro, scallions, curry leaves, dill)
  • Jalapeno slices

Instructions

  1. Thinly slice red onion (you’ll need one cup)
  2. Place the vinegar, water, salt, sugar and whole spices in a small pot on the stove and bring to a simmer. Add the onions, and simmer for 30-60 seconds, stirring. Turn off the heat.  Stir in any of the optional additions above. Let this cool completely.
  3. Place in a clean jar and store in the fridge for up to 3 weeks.

Notes

Vinegar:  White vinegar is more concentrated than other kinds of vinegar.  If subbing other vinegar like rice wine viniegar, apple cider vinegar or red wine vinegar, and you plan on keeping this for 3 weeks in the fridge, I would lower the water by 2 tablespoons. White vinegar will also ensure the clearest-looking pickling liquid and amplify the red onion’s color.

Pickled Onion Variations:

  1. Mexican pickled red onions: add sliced jalapeno and whole cumin seeds and coriander seeds, 1-2 whole clove seeds, garlic, plus Mexican oregano to the pickling liquid.
  2. Scandinavian pickled red onions: add fresh dill, caraway and peppercorns.
  3.  Indian pickled red onions: add fennel seeds, coriander seeds and either fenugreek, cilantro or curry leaves.

  1. Absolutely fabulous. I don’t even like vinegar but my husband does. I’m trying to get more used to it as so many low fat vegan options use it so thought I’d try your recipe as I’ve loved your recipes for a long time. Can’t believe it. I love the pickled red onions. I used white wine vinegar as I thought plain white would be too harsh. Perfect. Thank you






  2. I made these for a salad topping and it was SO delicious! You get such a great bite of flavor without the lingering pungency of the raw onion.






  3. These are now a staple in our fridge, we eat them with absolutely everything! Another fantastic, easy yummy recipe, thank you!!
