Step‑by‑Step Instructions for Sumac Onions
Step 1: Prepare the Onions
Begin by peeling and slicing two medium red onions into thin rings. A sharp knife will make this process easier. Aim for slices that are around 1/8 inch thick for optimal marinating. Once sliced, transfer the onions to a large mixing bowl, where their vibrant color will start to transform your kitchen.
Step 2: Add the Fresh Ingredients
Chop a handful of fresh parsley and add it to the mixing bowl with the onions. This herbaceous note is essential in balancing the sharpness of the onions. Next, sprinkle in about two tablespoons of sumac, which gives the Sumac Onions their signature tangy flavor, making them truly special.
Step 3: Mix the Marinade
Pour in three tablespoons of red wine vinegar and three tablespoons of extra virgin olive oil. As you drizzle the ingredients, envision how the acidity of the vinegar and richness of the oil will meld together to enhance the onions’ flavor. Using your hands, gently massage the mixture for a few minutes, ensuring all onion slices are well-coated and separated.
Step 4: Season to Taste
Sprinkle a pinch of kosher salt over the mixture, adjusting according to your taste preferences. Salt not only enhances the flavors but also helps draw out moisture from the onions. After seasoning, continue to massage the mixture briefly until everything is evenly combined and the onions start to soften slightly.
Step 5: Marinate and Rest
Let the Sumac Onions sit at room temperature for about 20 minutes. This resting period is crucial as it allows the flavors to meld beautifully while the onions become slightly translucent. You’ll see how the colors brighten as they absorb the tangy marinade, transforming into a vibrant, zesty condiment.
Step 6: Serve and Enjoy
After marinating, give the mixture one final gentle toss to ensure even distribution of flavors. Your Sumac Onions are now ready to be served! These zesty marinated onions make an exquisite topping for grilled meats or can be enjoyed as a refreshing side salad, brightening up any meal with their citrusy essence.

Make Ahead Options
These Sumac Onions are perfect for meal prep enthusiasts! You can slice the onions and prepare the marinade (parsley, sumac, red wine vinegar, olive oil, and salt) up to 24 hours in advance. Simply refrigerate the mixed marinade in an airtight container, and when you’re ready to serve, mix in the onions and allow them to marinate for about 20 minutes. This method lets the flavors develop beautifully while ensuring the onions remain crunchy. If marinated longer than 24 hours, the onions may become too soft, so it’s best to add them right before serving for just as delicious results!
