This pickled red onion recipe is easy and quick to make! It’s frugal and it goes great with many dishes such as my best burger recipe and Instant Pot beef brisket. Don’t forget about breakfast, this serves as a tasty topping for scrambled eggs! You will also learn tips and how to customize this delicious side dish.


  • 1 large red onion, peeled sliced very thin
  • 3/4 cup apple cider vinegar
  • 1/4 cup water
  • 1 teaspoon salt
  • 12 tablespoons sweetener (such as maple syrup, honey, sugar, etc.) – optional


  1. Combine the pickling mixture in a small saucepan on the stove and bring it JUST to a simmer. You don’t need to cook anything, but this lets the sweetener and additional seasonings dissolve and blend. (You can also do this in the microwave).
  2. While the mixture is on the stove, slice the onions. I use a chef’s knife, but a mandolin would be perfect here. The thinner the better!
  3. Combine the pickling mixture and the onions in glass pint jars and shake gently.
  4. Let the onions rest for 30 minutes and then serve!


Try different onions. Red onions have a natural bite to them, but yellow or white onions would be good too!
