Ingredients

  • 1 medium red onion thinly sliced
  • ¾ cup water
  • ⅔ cup apple cider vinegar
  • 3 tablespoons granulated sugar
  • 1 ½ teaspoons kosher salt

Instructions

    Cup of Yum
  1. Very thinly slice the onion.
  2. Optional: If your onion is very strong, place in a strainer and rinse under hot water 1 minute, tossing as you rinse.
  3. Bring water, cider vinegar, sugar, and salt to a boil. Add onion and boil 1 minute.
  4. Remove from heat and cover with a lid. Let sit 20 minutes.
  5. Place into jars and refrigerate at least 24 hours or up to 1 month.

Notes

  • Ensure you use kosher salt or coarse salt, the grains are larger. If you use table salt, reduce the amount or the onions will be too salty.
  • Short on jars? Put those old marinara sauce jars to good use and store your pickled onions in there!
  • Use the Liquid When the pickled red onions are gone, add some olive oil to the pickling liquid and whisk or blend for a zippy house-made salad dressing or add to your favorite marinade in place of vinegar!
  • Store pickled onions in a jar in the fridge for up to 1 month.
