Ingredients

  • 1 red onion
  • 1 pinch salt
  • ½ teaspoon oregano
  • ½ teaspoon garlic powder note 1
  • ¼ cup apple cider vinegar

Instructions

  • Slice- Slice onion in half through the root. Place cut side down and chop off the root and tip of bulb, peel skin off. Work slowly with a sharp knife to create the thinnest slices you can across the middle of the onion.

Notes

  1. swap garlic powder for 3-4 cloves fresh minced garlic if you'd like
  2. you can skip the microwave step and refrigerate onions overnight instead
  3. this recipe makes roughly 1 cup of pickled onions
Storage
  • Fridge - store in an airtight container in the fridge for up to 2 weeks
  • Freeze - we have never tried freezing these quick pickled red onions, but they would probably freeze/ thaw just fine. It might work well to portion out and freeze them in ice cube trays, too!
