Quick pickled red onions can be effortlessly prepared with only a few simple ingredients.

Quick pickled red onions are easy to prepare since they quickly absorb their flavor soaking in a sweet and tangy vinegar solution. The pungent heat from the sliced red onion dissipates overnight into a sweet crunch and a vibrant pink color. Its flavor is as bright as its appearance.

Quick Pickled Red Onion Ingredients

  • Red onions - You can also make refrigerator pickled onions with any other raw onions, like yellow onion or sweet onions.
  • Apple cider vinegar - Red wine vinegar, rice vinegar, or white vinegar can also be used.
  • Granulatedsugar - Sugar takes the bite off the vinegar, but it can be left out if you want a more astringent flavor. You can even substitute a different sweetener such as brown sugar, honey, or maple syrup.
  • Kosher salt - You can substitute pickling salt or table salt too, but cut the amount back to 2 teaspoons.
  • Customize this recipe - You can add different flavors with seasonings and fresh herbs. Suggestions include black peppercorns, crushed red pepper flakes, and garlic cloves.

How to make it

To cut an onion for this quick pickled red onion recipe, you want thin slices. Begin by slicing the onion in half through the stem with a sharp knife. Remove the dry outer leaves and then lay them cut side down on a cutting board. The onion can now be thinly sliced.

The vinegar, water, sugar, and salt are briefly boiled on the stovetop in a small saucepan to combine the sugar and salt. Once the sugar and salt have dissolved let the pickling solution cool. Then add your sliced onions to a quart jar (or similar glass jar) and fully submerge the slices with the brine. Place the onions in the refrigerator for at least one hour to pickle, but for the best flavor overnight is better.

How Long do Pickled Red Onions Last?

When stored properly in the refrigerator in an airtight container your pickled red onions will last about 2 weeks. I find the flavor and texture to be best the second day, as the color will slowly bleed out and the red onion slices will begin to soften over time.

      Sure, it will change the flavor a bit, but it will still work.

    I slice my onions on a mandolin. Makes super thin slices and no crying cause I leave the root intact. I love how uniform the slices are which give such a nice presentation. Since I cannot slice bread straight, it’s too much to expect nicely sliced onions.

    Can I use table salt or sea salt. I don’t have kosher salt

    Reply

    • Fox Valley Foodie

      You can, but the quantities will be different because of the different grain sizes. Table salt also has iodine which will discolor the brine if you let it sit for a long time, but it won't affect the taste.

    Do you think I could use this same recipe except for carrots instead of red onions?

    I'm trying this recipe today. I noticed on other recipes the instructions were to heat the ingredients first then pour over onions. This recipe doesn't say that. So, do I need to heat the ingredients first? Thanks!

    Reply

    • Fox Valley Foodie

      Heating can help the sugar and salt dissolve, but it isn't needed if you whisk good enough. You can heat the ingredients, but you will need to cool it off completely before pouring it over the onions so you do not cook them.

    I cannot tolerate sugar. It gives me dumping syndrome, if you know what that is, then you know it's miserable and painful. Can I substitute a sugar replacement such as Dplenda or Truvia for the sugar in this?

      Give it a try. I never use the stuff, so I can't really say. It would be a worthwhile experiment. Let me know how it turns out!

    The recipe says it makes one quart. Is this correct? ONE onion makes a quart of pickles?

    Reply

    • Fox Valley Foodie

      Yes, you can see I used a quart jar in the pictures too. When sliced the onions take up more space.

    When you say it keeps for a long time, how long exctly? I was hoping to make a lot and keep jars of them in the pantry.

    Reply

    • Fox Valley Foodie

      This recipe is meant to be kept in the refrigerator. Though the recipe is high in vinegar and sugar, I don't recommend storing it in your pantry as you could risk food poisoning. Even if you canned it I wouldn't recommend it because the heat from canning would degrade the texture of the onions. Regardless, even though they keep in the fridge for a couple weeks, I find the texture of the onions is best if enjoyed within a few days anyhow.

    Do you think you could sub honey or maple syrup? I don't use sugar. This looks so yummy!

    Reply

    • Fox Valley Foodie

      I would use honey over maple syrup. Heat the honey and vinegar together in a saucepan and stir to dissolve and let cool before adding the onions. I suspect it would work just fine.

    Your pickled onions look lovely! Since I wear contact lenses the onions don't even faze my eye, but you are right, a good knife is an essential tool. I also have the wustof chef knife. Love it!

      The eyes only water when cutting Onions, if you cut them wrong! Don't cut off the Top part, then it won't release the oils that causes you pain! 🙂
