I love pickled onions. I love pickled anything, really – beets, peppers, pickles. All are delicious in my book.

I always thought the process of pickling things took forever or was overly complicated. It’s actually so easy. If you’re pickled veggie-obsessed like I am, you’ll be ready to pickle everything after you see how easy it really is. There’s no long brining time or canning process required!

Ingredients for Quick Pickled Red Onions:

Here are some notes on what you’ll need to make this recipe. Check out the recipe at the bottom of this post for the full details and measurements.

  • Red Onions: You’ll want to thinly slice them so they can absorb all that vinegar quickly. I usually hand-slice them, but if you have a mandoline handy, even better!)
  • Vinegar: I use white wine vinegar (not regular white vinegar – it’s too harsh) but you can also use red wine vinegar, apple cider vinegar or rice wine vinegar. Not sure what to use? Check out this Guide to Vinegars.
  • Sugar: Your standard white sugar is perfect here. You can also use honey, maple syrup or another sweetener if you prefer.
  • Salt: Salt helps enhance flavors, so adding a little bit will really bring out the flavor here.
