Instructions:
Preparation is key. The first step to making your own pickled red onions is to prepare the star of the show: the red onion. You’ll want to peel the outer papery skin from your large red onion. Then, you’ll slice it thinly. The best way to achieve uniform slices is to cut the onion in half from root to stem. Lay each half flat on your cutting board and slice it as thinly as you possibly can. A mandoline slicer is ideal for this, as it ensures incredibly consistent, paper-thin slices that pickle beautifully. If you don’t have a mandoline, a sharp knife will work just fine, but take your time to get them as thin as possible. The thinner the slices, the more surface area there is for the pickling liquid to penetrate, resulting in a more evenly flavored and tender onion. Once sliced, you can gently separate the rings.
Create the brine. While you’re busy slicing your onions, it’s time to prepare the pickling brine. In a small saucepan, combine the 1 cup of white vinegar, 1 cup of water, 1 tablespoon of sugar (or your preferred sweetener), and 2 teaspoons of kosher salt. Place the saucepan over medium heat. Stir the mixture frequently until the sugar and salt have completely dissolved. You don’t need to bring the liquid to a rolling boil, just heat it enough to ensure everything is incorporated. This warm brine helps the flavors meld together beautifully and speeds up the pickling process. Once dissolved, remove the saucepan from the heat.
Combine and let the magic happen. Now for the easy part! Take your thinly sliced red onions and place them into a clean, heatproof glass jar or a sturdy bowl. The jar is ideal if you plan to store them in the refrigerator for later, as it’s more airtight. Make sure the jar is large enough to comfortably hold all the onion slices and the brine. Pour the warm pickling brine over the sliced red onions. Ensure that all the onion slices are submerged in the liquid. You might need to gently press them down with a spoon to make sure they’re fully covered. If any stragglers are floating, you can add a little more water to the brine to top it off.
The waiting game (and it’s a short one!). This is where patience, or rather, the lack of it, comes into play. Let the onions sit in the brine at room temperature for at least 30 minutes. During this time, you’ll witness a beautiful transformation. The vibrant pinkish-red of the raw onion will begin extract to deepen and intensify as it absorbs the pickling liquid. The onions will also soften slightly, losing their raw crunch and becoming tender yet still retaining a pleasant bite. The longer they sit, the more pronounced the pickling flavor will become. For a milder tang, 30 minutes is sufficient. For a more assertive pickle, you can let them sit for up to an hour.
Chill and enjoy! After the initial waiting period, it’s time to chill your pickled red onions. If you used a jar, you can simply put the lid on and place the jar directly into the refrigerator. If you used a bowl, transfer the onions and brine into an airtight container or a glass jar. Refrigerate for at least another 30 minutes before serving. This cooling period is crucial for both flavor development and texture. The cold temperature helps to firm up the onions slightly and allows the flavors to fully meld and mature. Once chilled, your pickled red onions are ready to be used! They will continue to develop flavor in the refrigerator for up to two weeks, becoming even more delicious over time. Give them a gentle shake or stir before each use to redistribute the brine.
These pickled red onions are incredibly versatile. Add them to your morning avocado toast for a zesty kick, layer them onto burgers and hot dogs for a gourmet touch, or scatter them over grilled meats and fish. They are also a fantastic addition to grain bowls, grain salads, and even potato salad. Their bright acidity cuts through richness, making them a perfect counterpoint to fattier dishes. Experiment and find your favorite ways to enjoy them!

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 last for at least 2-3 weeks. The longer they sit, the more the flavors will meld and deepen, but they are best enjoyed within that timeframe for optimal freshness and crunch.
Can I use a different type of onion?
While red onions are preferred for their color and slightly milder flavor when pickled, you can technically use other onions like white or yellow. However, they won’t have the same visual appeal, and the flavor profile might be a bit sharper. Red onions are definitely the star of the show for this particular recipe.
What if I don’t have apple cider vinegar?
If apple cider vinegar isn’t available, you can substitute it with white vinegar or red grape juice vinegar. The flavor will be slightly different, but it will still produce delicious pickled onions. Just ensure the vinegar has a similar acidity level for the pickling process to work effectively.
