How to Customize Pickled Onions

There are endless options to customize pickled red onions to your taste or for your cuisine. One thing is for certain, even if you do not prefer onions (like my daughter), these pickled onions will change your mind! The sharp flavor is replaced with a tangy fermented zip.

Choose rice vinegar if your primary use is in asian cuisine. Add cumin, coriander and Mexican oregano for Spanish flare. Add jalapeno or cayenne to spice it up. Apple cider vinegar has great nutritional benefits but also provides the most intense vinegar taste. Sugar is optional and I’ve not found significant flavor difference if using maple syrup vs honey or granulated sugar vs. leaving it out completely.

  • Cut onions in half then slice as thinly as possible into half-circle slices.
  • A sharp knife or mandoline for 1/8 inch thick slices.
  • A mason jar with a secure lid works best for storing.
  • Pickled onions are ready to eat when they are bright pink and tender. This could take anywhere from 1-4 hours depending on thickness of onion slices.
