Quick pickled red onions are a fast, colorful condiment that adds crunch, acidity, and a lightly sweet flavor to everyday meals. This simple recipe uses a hot brine to soften raw red onion slices just enough while keeping their crisp bite. In about 15 minutes, you will have a versatile topping ready for tacos, grain bowls, salads, sandwiches, burgers, grilled meats, and roasted vegetables. The flavor improves as they rest, but they are already delicious soon after cooling.
