Preparing the Onions:
The first step is to get your red onions ready for pickling. You’ll want to peel them, which is usually a simple process. Trim off the very top root end and the stem end. Then, slice each onion in half from pole to pole (through the root and stem ends). This direction of slicing is important because it helps the onion rings hold their shape better once they are sliced and submerged in the brine. After halving, peel away the papery outer skin. It might take a little effort to get it all off, but try to remove as much as possible. Next, you’ll thinly slice each onion half. A mandoline slicer is fantastic for achieving uniform, thin slices, which will ensure even pickling. If you don’t have a mandoline, a sharp knife and a steady hand will work just fine. Aim for slices that are about 1/8-inch thick. The thinner the slices, the quicker they will pickle and the more tender they will become. Place all your sliced onions into a heatproof bowl.
Making the Pickling Brine:
While your onions are waiting, it’s time to create the magical pickling brine. In a small saucepan, combine the water, white vinegar, sugar, and sea salt. If you’re opting for a little heat, now is also the time to add your red pepper flakes. You can adjust the amount of red pepper flakes to your personal preference – a little goes a long way for a subtle warmth, while more will deliver a noticeable kick. Place the saucepan over medium heat on your stovetop. Stir the mixture frequently, ensuring that the sugar and salt dissolve completely. You don’t need to bring the mixture to a rolling boil, just heat it until it’s hot enough that all the solids have dissolved and the liquid is steaming. This usually takes just a few minutes. The heat helps to infuse the flavors and, importantly, it will help to slightly wilt the onions as it’s poured over them.
Combining and Brining:
Once the brine is hot and the salt and sugar are fully dissolved, carefully remove the saucepan from the heat. It’s crucial to pour this hot brine over the sliced red onions immediately. Be careful, as the liquid will be hot. Pour the entire contents of the saucepan – brine and any dissolved spices – over the onions in the bowl. Make sure that all the onion slices are submerged in the liquid. You might need to gently press them down with a spoon or spatula to ensure they are fully covered. This step is where the magic really begin extracts. The heat from the brine will start to soften the onions and draw out their natural sharpness, replacing it with the tangy, sweet, and slightly spicy flavors of the pickling liquid.
Cooling and Infusing:
After you’ve poured the hot brine over the onions and ensured they’re submerged, the next step is to let them cool down. You can leave the bowl on your countertop at room temperature for about 30 minutes to an hour. During this time, the onions will continue to soften and absorb the flavors of the brine. You’ll notice the color of the onions starting to deepen and become more translucent as they pickle. The liquid will also start to take on a beautiful pink hue from the red onions. Once they have cooled sufficiently, it’s time to transfer them to a clean jar for storage. I prefer glass jars with airtight lids, such as mason jars. Carefully spoon the pickled onions and their brine into the jar. Make sure you get all the brine in there – it’s packed with flavor!
Storage and Enjoyment:
Seal the jar tightly with its lid. The pickled red onions are technically safe to eat immediately, but they will develop their best flavor and texture after at least a few hours in the refrigerator. For optimal results, I recommend letting them sit in the fridge for at least 24 hours. This allows the flavors to meld and the onions to become perfectly tender-crisp. They will last for several weeks in the refrigerator, making them a fantastic long-lasting condiment. To use them, simply drain off any excess brine if you prefer a less vinegary bite, or add them directly to your dish along with some of the pickling liquid. They are wonderful on tacos, burgers, sandwiches, salads, grain bowls, or even as a garnish for grilled meats and fish. Experiment and find your favorite ways to enjoy them!
Notes on Sugar: I like using granulated sugar as it’s readily available and works perfectly. However, you can also experiment with other sweeteners like honey or maple syrup for a slightly different flavor profile. If using honey or maple syrup, you might want to reduce the quantity slightly as they can be sweeter than granulated sugar.
Conclusion:
And there you have it – the simple yet transformative power of pickled red onions! This recipe is a true game-changer because it elevates almost any dish with a burst of tangy, slightly sweet, and vibrant flavor. It’s incredibly easy to make, requires minimal ingredients, and offers a beautiful pop of color that makes your meals more appealing. The bright pink hue is absolutely gorgeous, and the taste is simply addictive.

These delightful pickled red onions are incredibly versatile. I love them piled high on tacos, smashed avocado toast, burgers, salads, and even in sandwiches.

If you’re feeling adventurous, consider adding a pinch of chili flakes for a spicy kick, a bay leaf for subtle herbal notes, or even a few peppercorns for extra depth. The possibilities are endless. I truly encourage you to give this recipe a try. You’ll be amazed at how a simple jar of pickled red onions can transform your everyday cooking into something extraordinary.
Frequently Asked Questions:
How long do pickled red onions last?
When stored properly in an airtight container in the refrigerator, your pickled red onions should stay fresh and delicious for about 2 to 3 weeks. The longer they sit, the more mellow the flavor becomes, which can be a nice change for some!
Can I use a different type of onion?
While red onions are ideal for their color and slightly sweeter flavor, you can technically pickle other onions like white or yellow onions. However, they won’t achieve the vibrant pink hue and might have a sharper taste.
What if I don’t have apple cider vinegar?
White vinegar or rice vinegar are excellent substitutes for apple cider vinegar. They will still provide the necessary acidity to pickle the onions effectively, though the flavor profile might be slightly different. Red grape juice vinegar can also work, but it might impart a deeper color and a more pronounced grape juice flavor.
