Pickled Red Onions

Do you love pickled red onions? Unlike their raw, crunchy, and often spicy, counterparts, pickled red onions are deliciously tangy, crisp, and fresh. If you’ve never tried pickled red onions, or you’re not a huge fan of raw onions, I highly recommend this super easy method for making your very own right at home.

Some of you have asked where to buy pickled red onions? Fortunately, pickled onions are super easy to find at your local supermarket by the olives and other pickled vegetables. You can also order pickled red onions online.

How to Make Pickled Red Onions

This recipe is for quick-cook pickled red onions and not intended for canning.

For the full list and amounts of ingredients, scroll down to the recipe card at the bottom of the page.

Helpful tools and equipment

  • Sharp Knife or Mandoline slicer
  • Fine Mesh Strainer
  • Glass jars – I especially love my Weck Jars or Mason Jars with screw-on lids.
  • Saucepot

Optional pickling additions

Before I walk you through how to make pickled red onions, let’s quickly chat about pickling additions. What are pickling additions? They’re any ingredient other than the main four (red onion, vinegar, sugar, and salt) that enhance or change the flavor of your onions.

These “optional additions” are completely optional. If you don’t want to go through the hassle of adding additional flavors or spices to your pickled red onions, then don’t. Really. Seriously. Full transparency, I don’t think the add-ins do a WHOLE LOT to really change or alter the flavor. However, it is fun to play around with different things to see what happens.

Here are some of the most popular:

  • Whole peppercorns
  • Citrus peel- in this recipe I used orange peel
  • Whole garlic cloves
  • Dried chilis
  • Fresh herbs- rosemary, thyme, oregano, bay leaves
  • Whole star anise
  • Sliced habanero peppers
  • Spices- cumin or allspice

How to pickle red onions

  1. Slice your onions. Grab 1-2 small red onions. Peel and slice your onions nice and thin. I like my onions extra thin and equally sized, so the Mandoline slicer is my go-to. If you prefer somewhat thicker onions, a sharp chef’s knife should do the trick just as well. Keep in mind, however, that thicker onions will require a longer initial rest in the vinegar before they are ready to eat.
  2. Prepare jars. Thoroughly wash and dry your jars so they’re nice and clean. Add the salt, sugar, and any optional pickling additions to your jar(s). Fill each jar half-way with vinegar (I used plain rice vinegar), mix well to combine and set aside.
  3. Boil water and blanch the onions. Transfer your sliced onions to a colander or a fine mesh strainer resting over a large bowl. Bring approximately 4-5 cups water to a rolling boil in a medium saucepot over high heat. Once boiling, immediately remove from heat and slowly pour the water over the onions, mixing the onions as needed to ensure that they all “feel” the shock of the boiling water.
  4. Combine. Immediately transfer the blanched red onions to the prepared jar with the vinegar mixture. Fill the jar with additional vinegar (or boiling water), if needed. Stir well to combine.
  5. Pickle. Allow your onions to set for at least 30 minutes. After 30 minutes – BOOM! Serve on all your favorite recipes

What Vinegar Should be Used for Pickling Red Onions?

From what I understand, there is no hard and fast rule here. Some people use apple cider vinegar, others use white vinegar. My advice?

  • Use a clear vinegar (aka, no balsamic vinegar here, folks).
  • Avoid super harsh big-bottle white vinegar. You know, the kind of vinegar you would use in making your own homemade house cleaners.

What vinegar did I use in this recipe? I used plain rice vinegar. Of course, you don’t have to use this same type of vinegar. Other delicious vinegar options include,

  • apple cider vinegar
  • white wine vinegar

Try Pickled Red Onions On,

Everything! Ok, just kidding. Maybe not everything. But, almost…

Pickled onions taste fantastic on a variety of different recipes with different flavors and textures. They are especially welcome on dishes needed a tangy or crunchy kick.

  • Sandwiches – any and all kinds of burgers, wraps, or sandwiches including this bbq chicken sandwich, Mediterranean grilled turkey burgers, or my favorite herbed goat cheese and avocado sandwich.
  • Mexican favs – nearly all Mexican food loves a little pickled red onion. Add to your favorite beef tacos, tostadas, chilaquiles, or chicken mole.
  • Salad – Of course there may be a few exceptions here, but almost any salad with a creamy dressing will benefit from a few tangy pickled red onions. A couple of ideas to get you started include my chickpea tomato salad with creamy yogurt dressing or this mango avocado salad. Of course, let’s not forget creamy egg salad or chicken salad which always loves a little added crunch!
  • Breakfast food – specifically eggs (pan-fried, poached, hard-boiled eggs), avocado toast, eggs on top of avocado toast…
