Notes about this recipe

  • Store the final product in a Mason Jar. Takes up less space in your fridge.
  • Use a funnel to drain the vinegar mixture into the mason jar.
  • Use tongs to put the onion in the jar.
  • Simmer the onion along with the vinegar for about 5 minutes to soften the onion a bit.
  • As the onion sits, the flavor intensifies. For best results, allow to marinate overnight!

Tips for slicing the red onion

  • We like our onion slices in half moons, so I slice the top and bottom off of the onion and toss the outer layer of crunchy skin.
  • Then, I slice the onion in half from top to bottom.
  • Then, cut side down, I slice each half in ¼ inch pieces.

How long do pickled red onions last?

Pickled red onions will keep up to a month in the refrigerator. We find these so addictive they never last that long!

Variations (pickling other veggies)

You can also use this recipe to “quick pickle” other veggies like cucumbers, okra, peppers, etc. with one small change…

Instead of red wine vinegar, use regular vinegar. Otherwise, the “red” in the red wine vinegar adds a pink-ish color to the veggies.


Yield: 1 onion
