Preparation is Key
The first step in creating these beautiful pickled onions is to prepare your star ingredient: the red onion. Start by peeling the outer papery skin off the entire onion. Once peeled, you’ll want to trim off the very top stem end, but leave the root end intact for now. This will help keep the onion slices together as you cut them. Next, slice the onion as thinly as possible. The thinner the slices, the quicker they will pickle and the more tender they will become. A mandoline slicer is ideal for achieving uniform, paper-thin slices, but a sharp knife and a steady hand will also do the trick. Aim for slices that are almost translucent. As you slice, you can discard the root end if it becomes difficult to handle. Once all your onion is sliced, you can gently separate the rings if they are sticking together. These delicate rings are now ready for their flavorful bath.
Crafting the Brine
While your onion slices are ready, it’s time to make the pickling brine that will infuse them with incredible flavor. In a small saucepan, combine the white vinegar and water. White vinegar is a classic choice for pickling as its clean, sharp flavor is perfect for this purpose, but you could experiment with apple cider vinegar for a fruitier note. Add the sugar and kosher salt to the liquid. The sugar, as mentioned, adds a touch of sweetness to balance the tang of the vinegar, but it’s entirely optional if you prefer a more purely sour pickle. Kosher salt is preferred for its larger, flakier crystals which dissolve easily and provide a clean salinity without any anti-caking agents that can sometimes cloud pickling liquids. Place the saucepan over medium heat. Stir the mixture gently until the sugar and salt have completely dissolved. You don’t need to bring it to a rolling boil, just a gentle simmer to ensure everything is well incorporated. Once dissolved, remove the saucepan from the heat.
The Magic of the Bath
Now for the most satisfying part: submergin extractg those beautiful red onion slices into their flavorful brine. You will need a clean, heat-proof jar or container. Glass jars with tight-fitting lids are perfect for this, as they allow you to see the pickling process and store the onions effectively. Carefully place all of your thinly sliced red onions into the jar. Make sure they are packed in relatively loosely, allowing the brine to circulate around them. Now, carefully pour the warm brine mixture over the onions. Ensure that the onions are completely submerged in the liquid. If any slices are poking out, gently push them down with a spoon or add a little more water or vinegar mixture if you have it on hand. As the warm brine hits the onions, you’ll immediately notice a change in their color. They will begin extract to transform from their raw, vibrant red to a stunning, translucent pink. This is the magic of pickling happening before your eyes!
The Waiting Game (And the Rewarding Outcome)
Once the onions are submerged in the brine, secure the lid on your jar tightly. Now comes the patience part! For the quickest results, you can let the jar sit on the counter at room temperature for about 30 minutes. During this time, the onions will soften slightly and absorb the flavors of the brine. You’ll notice the brine itself turning a beautiful pinkish hue as it draws the color from the onions. However, for the best flavor development and texture, I highly recommend refrigerating the pickled onions. Once they have cooled down to room temperature, transfer the jar to the refrigerator. They will continue to pickle and meld in the cool environment. While they are technically edible after 30 minutes, I find that they reach their peak deliciousness after at least a couple of hours, and they are even better after a full day. The longer they sit in the fridge, the more pronounced and well-rounded their flavor will become. They can be stored in the refrigerator for up to two weeks, though they rarely last that long in my house!
Serving Suggestions and Enjoyment

When stored properly in an airtight container in the refrigerator, your pickled red onions should stay delicious for at least 2-3 weeks. The longer they sit, the more the flavors meld and develop, often becoming even more delicious!
Can I adjust the sweetness or tangin extractess?
Absolutely! This recipe is a great starting point. For a sweeter pickle, you can increase the sugar slightly. For a tangier result, add a little more vinegar. Taste as you go and adjust to your personal preference. You can even experiment with different vinegars like apple cider vinegar for a slightly different flavor profile.
What if I don’t have red onions?
While red onions are ideal for their vibrant color and slightly milder flavor when pickled, you can technically pickle other types of onions. White or yellow onions will work, but they won’t have the same visually appealing pink hue. The pickling process will still impart that desirable tangy flavor.
