Instructions:
The beauty of pickled red onions lies in their simplicity. The process involves a quick brine and a short resting period, after which the magic of transformation begin extracts. Let’s get started!
Prepare the Onions:
Start by peeling your red onions. You want to remove the papery outer skin. Then, slice them thinly. A mandoline slicer is your best friend here for achieving uniformly thin, delicate rings, which absorb the brine beautifully and create a lovely texture. If you don’t have a mandoline, a sharp knife will work, just do your best to keep the slices as consistent as possible, about 1/8-inch thick. The thinner the slice, the quicker they will pickle and the more tender they will become. Once sliced, you can either place them directly into your clean jar or a heat-proof bowl. I prefer using a mason jar for storage later, so I often slice them directly into a wide-mouth mason jar. If you find the onion aroma too potent, you can rinse the sliced onions under cold water and pat them dry, but this can slightly dilute their flavor.
Make the Brine:
In a small saucepan, combine the water, white vinegar, sugar, and sea salt. If you’re opting for a little heat, now’s the time to add your red pepper flakes. Stir everything together and place the saucepan over medium heat. We’re not looking for a rolling boil here; we just want to heat the liquid until the sugar and salt have completely dissolved. This usually takes just a few minutes. Stirring occasionally will help speed up the dissolution process. Once you see that all the granules have disappeared and the liquid is clear, remove the saucepan from the heat. The type of sugar you use can subtly affect the flavor and color. Standard granulated sugar is fine, but you can also experiment with coconut sugar for a slightly caramelly note or even maple syrup for a richer sweetness, though this will alter the color more significantly. White vinegar provides a clean, sharp tang that is ideal for pickling, but apple cider vinegar can also be used for a slightly fruitier profile.
Combine and Infuse:
Carefully pour the hot brine over the sliced red onions. Make sure that all the onion slices are submerged in the liquid. If you’re using a jar, this is where you’ll see the color start to change almost immediately. If the onions aren’t fully covered, you can add a splash more water and vinegar in equal parts until they are. Gently stir the onions in the brine to ensure even distribution and to help them start to wilt and soften. You’ll notice the liquid turning a beautiful pinkish-purple as it interacts with the onions. This infusion process is where the flavor really starts to develop. The heat of the brine also helps to slightly “cook” the onions, making them tender and ready to be enjoyed sooner.
Cool and Marinate:
Allow the onions to sit at room temperature in the brine for at least 15 to 30 minutes. This initial resting period allows the flavors to meld and the onions to soften further. You can observe the dramatic color change happening during this time. The longer they sit, the more intense the pickling flavor will become. For a milder pickle, 15 minutes might be sufficient. For a more pronounced tang, let them sit for the full 30 minutes or even a bit longer. Once they’ve reached your desired level of tenderness and tang, you can transfer the onions and their brine into an airtight container, like your clean mason jar. Ensure the onions are fully submerged in the brine. Any remaining liquid from the saucepan can also be poured into the jar. If you plan to store them for longer than a few days, a clean glass jar is the best option.
Chill and Enjoy:
Once the onions are in their storage container, seal it tightly and refrigerate. The real magic of pickling happens as they chill. For the best flavor and texture, I like to let them sit in the refrigerator for at least an hour before using them, but they are usually delicious after just 30 minutes if you’re impatient. Overnight is even better, as the flavors deepen and meld wonderfully. These pickled red onions will keep in the refrigerator for about 2-3 weeks, making them a fantastic make-ahead condiment. Before serving, you can drain them slightly, or use them with a bit of the pickling liquid for extra flavor. They are incredibly versatile and add a welcome burst of acidity and color to so many dishes. Try them on avocado toast, mixed into a potato salad, as a topping for grilled fish, or simply by the forkful!
Enjoy your homemade pickled red onions – they’re a game-changer!
