Ingredients:
Preparing the Onions
The first step in creating our delicious pickled red onions is to prepare the star ingredient: the red onions. You’ll want to peel the outer papery skins from your onions. This is usually quite simple. Once peeled, trim off the root end and the stem end. For the best results, and to ensure even pickling, I like to slice the onions thinly. A mandoline slicer is fantastic for this, as it will give you uniformly thin slices, but a sharp knife and a steady hand will work just as well. Aim for slices that are about 1/8 to 1/4 inch thick. The thinner the slices, the faster they will pickle and the more pliable they will be in your final dish. I usually aim to slice them into half-moons, following the natural curve of the onion. Don’t worry if some of the rings break apart; it’s all good. Place your beautifully sliced onions into a heatproof jar or a large bowl. I highly recommend using a glass jar with a lid for storage, as it’s non-reactive and keeps the onions fresh. A mason jar is perfect for this purpose.
Crafting the Brine
Now, let’s move on to creating the pickling brine, which is where all the magic happens. This mixture of liquids and seasonings is what will transform our humble red onions into their tangy, vibrant selves. In a medium saucepan, combine the water, white vinegar, sugar, and sea salt. If you’re feeling a bit adventurous and want a subtle hint of heat, now is the time to add your red pepper flakes. I usually start with 1/4 teaspoon and can always add more if I want a spicier batch. Stir everything together to help dissolve the sugar and salt. Place the saucepan over medium heat on your stovetop. We need to bring this mixture to a simmer, but it doesn’t need to come to a rolling boil. You’ll see small bubbles forming around the edges of the pan and steam rising. This gentle simmering helps to meld the flavors and ensures that the sugar and salt are fully dissolved.
The Transformation Begin extracts
Once the brine has reached a simmer, carefully remove it from the heat. Now for the exciting part! Gently pour the hot brine over the sliced red onions in your jar or bowl. Make sure that all the onion slices are completely submerged in the liquid. You might need to give them a gentle push down with a spoon to ensure they are fully covered. The hot brine will immediately start to work its magic on the onions. You’ll notice the onions begin extract to soften slightly and their vibrant color will start to deepen and spread into the brine, turning it a beautiful pink. This visual cue is incredibly satisfying!
Cooling and Infusing
This is where patience truly pays off. Allow the onions and brine mixture to cool down to room temperature. This typically takes about 1 to 2 hours, depending on how hot your kitchen is. As it cools, the onions will continue to absorb the flavors of the brine and become even more tender. Once the mixture has completely cooled, you can cover your jar or bowl. If you’re using a jar, simply screw on the lid. If you used a bowl, you can cover it tightly with plastic wrap. Now, it’s time for the onions to do their best work in the refrigerator.
Storage and Enjoyment
For the best flavor and texture, I recommend letting the pickled red onions chill in the refrigerator for at least 30 minutes to an hour before using them. However, they truly shine after a few hours or even overnight. The longer they sit, the more the flavors will meld and the more tender and tangy the onions will become. Once they’ve reached your desired level of pickling, they are ready to be enjoyed! These pickled red onions will keep in an airtight container in the refrigerator for at least 2 to 3 weeks, and often longer. The acidity of the vinegar acts as a natural preservative. You can use them as a topping for tacos, burgers, sandwiches, avocado toast, salads, or even stirred into dips and sauces. They add a delightful pop of color and a refreshing, slightly sweet, and tangy counterpoint to richer flavors. Enjoy experimenting with all the ways you can incorporate these delicious pickled red onions into your meals!
