I love making pickled red onions at home because they add a perfect burst of flavor and color to so many dishes—from salads and tacos to sandwiches and grilled meats. What’s great about this recipe is its simplicity and quick prep time. I usually slice a large red onion very thinly to ensure it soaks up the vinegar brine well. One tip I found helpful is to use a combination of white vinegar or apple cider vinegar, depending on the flavor profile you prefer. Apple cider vinegar gives a slightly fruity tang, while white vinegar keeps it sharp and classic. Dissolving one tablespoon each of salt and sugar in hot water before adding the vinegar ensures the flavors blend smoothly and helps maintain a nice balance between sweet and sour. After filling the jar with sliced onions and pouring the warm brine over them, I leave the jar out on the counter until it cools to room temperature. Then I store it in the fridge where the onions turn a beautiful bright pink color in just a few hours. They keep well for about 3 to 4 weeks if refrigerated and are perfect for meal prepping. This easy recipe is budget-friendly and perfect for those who want to make condiments from scratch without complicated ingredients. It’s also a fun way to reduce food waste—using fresh, crunchy red onions sourced locally whenever possible. Plus, having a jar of homemade pickled onions always elevates any dish, making it a staple in my kitchen that I highly recommend everyone tries at least once.
