Instructions:
1. Prepare the Onion: The first step is to get your red onion ready. For the best results and uniform pickling, I like to slice the onion very thinly. You can achieve this by using a sharp chef’s knife and a steady hand, or for even thinner and more consistent slices, a mandoline slicer is your best friend here. Remember to be careful if using a mandoline; they are sharp! Peel the red onion, cut it in half from root to stem, and then lay the flat side down on your cutting board. Slice thinly, aiming for rounds or half-moons, depending on your preference. The thinner the slices, the quicker they will pickle and the more tender they will be. You’ll notice how beautifully vibrant the raw onion is; this color will deepen and transform during the pickling process. Place these prepared onion slices into a clean glass jar or a heat-proof bowl. I recommend using a jar because it makes storing them super easy later. Make sure the jar is large enough to hold the onion slices comfortably and leave some room for the pickling liquid.
2. Create the Pickling Brine: Now, let’s get to the flavorful brine that will work its magic on those onions. In a small saucepan, combine the white vinegar, water, sugar, and kosher salt. Place the saucepan over medium heat on your stovetop. Stir the mixture gently until the sugar and salt are completely dissolved. You don’t need to bring it to a rolling boil, but you do want it to be hot enough to ensure everything is well incorporated. This simple brine is the heart of the pickling process, providing the acidity from the vinegar and the subtle sweetness from the sugar that balances the sharp onion flavor. The salt also plays a crucial role in drawing out moisture from the onions and helping to preserve them. Taste a tiny bit of the brine (carefully, it’s hot!) to adjust sweetness or saltiness if you like, though this ratio is a fantastic starting point.
3. Combine and Submerge: Once the sugar and salt have dissolved, carefully remove the saucepan from the heat. It’s time to bring the onion and brine together. Pour the hot pickling liquid directly over the sliced red onions in your jar or bowl. Ensure that all the onion slices are fully submerged in the liquid. If they aren’t completely covered, you can add a tiny bit more water and vinegar in equal parts until they are. Gently press down on the onions with a spoon if needed to help them sink beneath the surface. This even submersion is key to ensuring all parts of the onion pickle uniformly and absorb the flavors of the brine.
4. Cool and Chill: This is where the transformation begin extracts! Let the jar or bowl of onions and brine sit at room temperature for about 30 minutes to an hour. During this time, you’ll start to see the onions begin extract to soften and their color change from a deep purple-red to a more vibrant, translucent pink. After this initial cooling period, tightly cover the jar (if you used one) and place it in the refrigerator. The pickling process will continue in the fridge, and the flavors will meld beautifully. The longer they sit, the more pronounced the pickling will be.
5. Allow to Pickle and Enjoy: For the best flavor, I recommend letting the pickled red onions sit in the refrigerator for at least a few hours before diving in. Overnight is even better, as the onions will become more tender and absorb even more of the tangy, slightly sweet brine. You’ll notice a dramatic change in color; they’ll turn a beautiful, jewel-toned pink. Once they’ve had sufficient time to pickle, they are ready to be used! Drain them lightly before serving, or use them directly from the jar with a little bit of their brine. They will keep in the refrigerator for several weeks, making them an excellent make-ahead condiment for all your culinary creations. I love adding them to avocado toast, topping grilled burgers, mixing them into tuna salad, or even scattering them over roasted vegetables. The possibilities are truly endless, and the bright, zesty flavor they bring is addictive!
