Pickled Red Onion with Thyme

Paula D'Elia


Tangy and sweet, pickled red onions give sandwiches, salads, bowls, tacos and more a burst of bright flavor and color. They’re easy to make and, if you slice them super thin, require only the briefest amount of time in the brine to achieve pickled perfection. Want to infuse the onions with a little more of a bite? Add a few slices of jalapeño to the jar for a bit of heat.
