Ingredients

Scale

Ingredients

  • 1 large red onion, thinly sliced
  • 2 teaspoons sumac
  • 1/2 teaspoon salt
  • 1 tablespoon red wine vinegar or lemon juice
  • 1 tablespoon extra virgin olive oil
  • 1 tablespoon fresh parsley, chopped

Instructions

  1. Massage Onions: Add the thinly sliced red onions, sumac, and salt to a medium bowl. Use your hands to gently massage the salt and sumac into the onions for about 30-60 seconds to soften the onions and infuse the flavors.
  2. Add Remaining Ingredients: Add the red wine vinegar or lemon juice, extra virgin olive oil, and chopped fresh parsley to the bowl. Mix everything together thoroughly to combine.
  3. Marinate: Cover the bowl and set aside to marinate for at least 20 minutes. This allows the flavors to meld and the onions to mellow. You can also store the mixture in an airtight container for up to four days.
  4. Serve: Serve the sumac onions as a simple side salad or as a flavorful condiment. They’re perfect to add to burgers, sandwiches, wraps, salads, or any dish that needs a zesty onion kick.

Notes

  • Use either red wine vinegar or fresh lemon juice based on your preference or availability.
  • Marinating longer enhances the onion flavor while softening their bite.
  • Store in the refrigerator in an airtight container for up to 4 days.
  • Sumac adds a unique tangy and slightly lemony flavor, but if unavailable, a small pinch of lemon zest can be a substitute.
  • This recipe is naturally vegan and gluten free.
