Ingredients:
Preparing the Onions
The first step in creating your perfect pickled red onions is preparing the star ingredient: the onions themselves. You want to slice them thinly and evenly. This is crucial because it allows the brine to penetrate the onion slices effectively and also ensures that you get a consistent texture in your finished pickles. I find that a mandoline slicer is your best friend here, as it creates uniform, paper-thin slices in a flash. If you don’t have a mandoline, a sharp knife and a steady hand will do the trick. Aim for slices that are about 1/16th to 1/8th of an inch thick. You can either trim off the root end and peel the onions before slicing, or you can slice them in half from root to stem and then slice thinly from there, peeling off the outer layers once they are sliced. Whichever method you choose, make sure to discard the tough outer skins.
Creating the Brine
Next, we’ll create the magical brine that will transform our raw onions into tangy delights. In a medium saucepan, combine the water, white vinegar, sugar, and sea salt. If you’re feeling a little adventurous and want a hint of warmth, now is the time to add your red pepper flakes. The amount of red pepper flakes is entirely up to your spice preference. Start with 1/4 teaspoon if you’re unsure, and you can always add more next time. Place the saucepan over medium heat. Stir the mixture frequently to ensure that the sugar and salt dissolve completely. You don’t want to bring this mixture to a rolling boil; just heat it until the sugar and salt have dissolved and the liquid is hot. This usually takes just a few minutes. Once everything is dissolved, remove the saucepan from the heat.
Assembling and Infusing
Now comes the fun part: combining the onions and the brine. You’ll need a clean glass jar or container that can hold all of your sliced onions and the brine. A wide-mouth mason jar is ideal for this purpose. Pack the thinly sliced red onions snugly into your jar. Don’t be afraid to really fill it up, as they will shrink down a bit once they are submerged in the brine. Once the onions are in the jar, carefully pour the hot brine over them. Make sure that the onions are completely submerged in the liquid. If your jar is a bit too full, you might need to gently press down on the onions to submerge them. This ensures that every surface of the onion gets exposed to the pickling liquid.
The Waiting Game and Storage
Once the onions are covered in brine, let the jar sit at room temperature for about 30 minutes to an hour. This initial period at room temperature helps to further soften the onions and begin extract the pickling process. After this initial cooling period, tightly screw the lid onto your jar and transfer it to the refrigerator. This is where the magic really happens. The onions will continue to pickle and develop their flavor in the cold environment. While you can technically eat them after an hour or two, I find that they are best after at least 4 hours in the refrigerator. For the most developed flavor, allowing them to pickle overnight is ideal. You’ll notice the onions will become more vibrant in color and soften considerably. They will keep in the refrigerator for about 2-3 weeks, making them a perfect make-ahead condiment.
Tips and Variations for Perfect Pickles
A note on the sugar: I’ve suggested “sugar of choice” because while granulated white sugar is standard, you can experiment. Brown sugar will add a subtle molasses note, and maple syrup can lend a delicate sweetness with a hint of earthiness. Just be sure to adjust the liquid amount slightly if using something less granular than white sugar. You can also play with the vinegar. Apple cider vinegar will impart a fruitier tang, and red grape juice vinegar will add a deeper, more complex flavor profile. If you love garlic, throw in a smashed clove or two into the brine before heating. Similarly, peppercorns, bay leaves, or a sprig of fresh dill can add wonderful aromatic complexity. The key is to start with the basic recipe and then feel free to customize it to your heart’s content. These pickled red onions are truly a gateway to a world of flavorful possibilities.

Frequently Asked Questions:
How long do pickled red onions last?
Properly stored in an airtight container in the refrigerator, these pickled red onions can last for up to 2-3 weeks. The acidity in the brine acts as a preservative.
Can I use a different type of onion?
While red onions are ideal for their color and slightly milder flavor when pickled, you can certainly use white or yellow onions. However, they won’t have the same beautiful pink hue and may have a stronger, more pungent taste.
What if I don’t have apple cider vinegar?
You can substitute with white vinegar or red grape juice vinegar. Apple cider vinegar provides a nice balance of sweetness and tang, but other vinegars will still yield delicious results.
