Let’s dive in and learn how to create this pantry staple!
Ingredients:
Preparing the Onions
The first step in creating these beautiful pickled onions is to prepare your star ingredient: the red onions. For the best results, you’ll want to slice them thinly. This allows the brine to penetrate the onion slices effectively, leading to quicker pickling and a more pleasant texture. I prefer to slice them into thin half-moons, about 1/8-inch thick. You can achieve this using a sharp knife and a steady hand, or for absolute uniformity and speed, a mandoline slicer is a fantastic tool. Just be sure to use the safety guard! Once sliced, place the onion rings into a heatproof jar or a bowl. I like to use a glass jar with a tight-fitting lid, as this will be where they marinate and can be stored in the refrigerator.
Making the Brine
While your onions are waiting, it’s time to whip up the pickling brine. This is where all the flavor magic happens. In a medium saucepan, combine the water and white vinegar. The vinegar provides the essential acidity for pickling, and white vinegar offers a clean, neutral tang that lets the onion flavor shine. Next, add your sugar. I generally use granulated sugar, but feel free to experiment with other sweeteners like honey or maple syrup for a slightly different flavor profile (just be mindful that these can sometimes affect the color slightly). Whichever sugar you choose, the sweetness balances the acidity of the vinegar, creating a harmonious blend. Finally, add the sea salt. I recommend sea salt for its mineral content and clean taste, but any good quality salt will work. If you enjoy a little heat, now is the time to stir in the red pepper flakes. This is completely optional, but it adds a lovely subtle warmth that complements the onions beautifully.
Heating and Infusing the Brine
With all the brine ingredients in the saucepan, place it 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 heat it enough to ensure everything is dissolved. Once dissolved, remove the saucepan from the heat. This hot brine is crucial for softening the onions slightly and kick-starting the pickling process. The heat helps to draw out some of the onion’s natural sharpness and makes them more receptive to the pickling flavors.
The Brining Process
Now, it’s time to bring it all together. Carefully pour the hot brine over the sliced red onions in your jar or bowl. Make sure the onions are fully submerged in the liquid. If they’re not quite covered, you can add a splash more water and vinegar in equal parts, or even just a little more plain water if you’re worried about over-vining them. Gently press down on the onions to ensure they are all getting a good soak. This is where the beautiful color transformation begin extracts to occur. You’ll notice the onions starting to deepen in color as they sit in the brine.
Cooling and Marinating
Once the onions are submerged, let the mixture cool down at room temperature for about 30 minutes to an hour. This allows the initial heat to dissnon-alcoholic ipate before you seal the jar. After this initial cooling period, securely cover the jar with its lid and transfer it to the refrigerator. This is where the real pickling happens. The cold temperature slows down the enzymatic processes in the onions and allows the flavors of the brine to fully infuse them. You’ll want to let them marinate for at least an hour before using them, but they are truly at their best after several hours or even overnight. The longer they sit, the more tender and flavorful they become. You can store them in the refrigerator for up to two weeks, and they often taste even better a few days in as the flavors continue to meld. Enjoy the vibrant, tangy addition to your meals!

How long do pickled red onions last?
When stored in an airtight container in the refrigerator, your pickled red onions should stay fresh and delicious for at least 2 to 3 weeks, though many find they taste even better after a few days as the flavors meld.
Can I use other types of onions?
While red onions are ideal due to their vibrant color and slightly milder flavor when pickled, you can experiment with white or yellow onions. They might not turn as pink, and the flavor profile will be slightly different, but they will still be delicious!

If you find the brine too intense, you can dilute it slightly with a little more water or sugar. For future batches, you can also adjust the ratio of vinegar to water to suit your preference for tangin extractess.
