Sumac Onions Recipe

These quick and tangy Sumac Onions are a quick Middle Eastern condiment. Made with thinly sliced red onions, lemon juice, olive oil, and sumac, they add a refreshing, citrusy bite that balances rich dishes like kebabs, shawarma, or grilled fish. Serve as a side, condiment, or salad for a fresh pop of flavor.

  • 1 tablespoon sumac

Notes

  • Yields: This recipe makes ½ to ¾ of sumac onions, which would be ideal for serving 4 adults. The nutritional values below are per serving.
  • Onions: While the traditional recipe is made with red onions, in a pinch, you can use white onions, but keep in mind that the flavor profile will be slightly different.
  • Make Ahead: These onions get even better as they sit. You can prepare them 2-3 days in advance and store them in an airtight container or jar in the fridge.
  • Storage: Store leftovers in the fridge for up to 4 days. Just give them a quick stir before serving to mix the seasonings back in.
  • Freezing: Not recommended, as the onions lose their crisp texture once thawed. For the best flavor and crunch, enjoy them fresh.
