The Quick and Easy Process
Making your own pickled red onions is a wonderfully satisfying endeavor. The beauty of this recipe lies in its simplicity; you don’t need any fancy equipment or obscure ingredients. The key is to create a brine that will gently “cook” and infuse the thinly sliced onions, transforming them from sharp and pungent to tender and delightfully tangy. Let’s get started!
Prepare the Onion:
The first step is to get your red onion ready for pickling. You’ll want to peel the onion, and then slice it as thinly as possible. A mandoline slicer is your best friend here for achieving uniform, paper-thin slices. If you don’t have a mandoline, a very sharp knife will work, but take your time to ensure consistency. The thinner the slices, the more quickly they will pickle and the more tender they will become. Aim for slices that are almost translucent. Once sliced, place the onion rings into a clean glass jar or a heatproof bowl. I like to use a wide-mouth mason jar for easy access later.
Create the Brine:
Now, let’s make the magic happen with the brine. In a small saucepan, combine the white vinegar, water, sugar, and kosher salt. Place the saucepan over medium heat. Stir the mixture gently until the sugar and salt have completely dissolved. You don’t need to bring this to a rolling boil; just heat it enough to dissolve the solids. The vinegar provides the acidity for pickling, while the water dilutes it slightly to a more palatable level. The sugar adds a touch of sweetness to balance the tartness of the vinegar, and the salt is crucial for flavor and also plays a role in the pickling process. If you’re watching your sugar intake, feel free to omit it or use a sugar substitute like stevia or erythritol. Just be mindful that omitting sugar will result in a tarter pickle.
Combine and Infuse:
Once the sugar and salt are dissolved in the brine, carefully pour the hot liquid over the sliced red onions in your jar or bowl. Make sure that all the onion slices are fully submerged in the brine. If they aren’t, you can gently press them down with a spoon or add a little more water and vinegar in equal parts if needed. You want every piece of onion to be exposed to the pickling liquid for even flavor penetration. The hot brine will immediately begin extract to work its magic, softening the onions and starting the transformation process. You’ll notice the color of the onions begin extract to intensify and the brine taking on a beautiful pink hue as they release their natural pigments.
The Waiting Game (Patience is a Virtue!):
This is arguably the most crucial step, and it requires a little bit of patience, but the results are well worth it. Allow the onions to steep in the brine at room temperature for at least 30 minutes. During this time, the onions will continue to soften, absorb the flavors of the brine, and turn that gorgeous vibrant pink. The longer you leave them, the more pickled they will become. For a milder pickle, 30-60 minutes is usually sufficient. If you prefer a tangier, more deeply flavored onion, you can let them sit for a couple of hours, or even overnight at room temperature before refrigerating. However, for food safety, it’s best to refrigerate them after a few hours at most.
Chill and Store:
After the initial resting period at room temperature, it’s time to move your pickled red onions to the refrigerator. Seal the jar tightly (if using a jar) and place it in the fridge. The onions will continue to pickle and develop in flavor as they chill. They are typically best after at least an hour or two in the refrigerator, but they really shine after a day or two. The cold further slows down the pickling process and allows the flavors to meld beautifully. These pickled red onions will keep in the refrigerator for up to 2-3 weeks, making them a fantastic make-ahead condiment. Just remember to use a clean utensil every time you reach into the jar to avoid introducing any contaminants.
