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.

If you’re feeling creative, you can also add peppercorns, garlic, jalapeños or fresh or dried herbs to the mix to give your pickled onions a new flavor.

How to Pickle Onions:

Did I mention how easy pickling onions is? Here’s the general process:

  1. Prep the vinegar. Bring the vinegar, sugar and salt to simmer on the stove.
  2. Slice, slice, baby. Thinly slice those onions and place them in a mason jar or airtight container.
  3. Add the liquid. Pour the vinegar on top. Screw on the lid and give it a gentle shake to coat everything.
  4. Marinate. Place in the refrigerator and let sit at least 30 minutes before enjoying.

Once you have your pickled onions ready to go, the possibilities are endless. Top off tacos, burgers, salads and more with these tangy, tasty onions. They’ll keep in the refrigerator for up to 2 weeks so you can enjoy them on just about everything!
