Learn how to make easy pickled red onions with simple ingredients and minutes of prep. These quick pickled red onions add tangy crunch and vibrant color to tacos, bowls, and more.
Thinly slice the red onion and place it in a clean jar or airtight container.
In a small bowl or measuring cup, whisk together the water, white vinegar, sugar, and salt until the sugar and salt are fully dissolved.
Pour the vinegar mixture over the sliced onions, making sure the onions are fully submerged. Press them down gently if needed.
Cover and let the onions sit at room temperature for about 30 minutes if you need a quick pickle. They will soften and begin to take on flavor, though there may still be a slight bite to the onion.
For the best flavor and texture, refrigerate the onions for at least 4 hours before serving.
Store the pickled onions in the refrigerator in an airtight container for up to 1 week.
