Prep Time
10 minutes
Yield
1 cup
1½ cups boiling water
1 cup thinly sliced red onion (from 1 small onion)
1 tablespoon kosher salt, plus more to taste
3 tablespoons fresh lime juice (from 1 lime)
1½ tablespoons fresh orange juice
1½ tablespoons fresh grapefruit juice
Soften the Onions
In a medium heatproof bowl, combine the boiling water, sliced red onion, and kosher salt. Stir gently and allow the onions to soak for about 5 minutes, or until they become slightly translucent.
Cool the Onions
Drain the onions and rinse under cold water until completely cooled. This helps maintain their crisp texture while reducing some of the onion’s sharpness.
Marinate in Citrus
Transfer the onions to a small bowl or glass jar. Pour in the lime juice, orange juice, and grapefruit juice. Stir well to coat the onions evenly in the citrus mixture.
Season and Rest
Taste and add additional salt if desired. Allow the onions to marinate for at least 15 minutes before serving. For even better flavor, refrigerate them for 1 to 2 hours.
Serve
Enjoy these citrus pickled onions on tacos, burgers, sandwiches, grain bowls, avocado toast, grilled meats, seafood, or fresh salads.
Fresh citrus juice provides the best flavor and creates a brighter, more vibrant pickle.
