Ingredients You’ll Need

Base Ingredients

3 large red onions, thinly sliced into wedges – Provide crunch, sweetness, and the salad’s vibrant color.
3 tablespoons sumac powder – Adds acidity, color, and a distinctive lemony flavor without sharp sourness.

Seasoning & Dressing

2 tablespoons extra virgin olive oil – Softens the onions and carries the flavor of the spices.
1 tablespoon fresh lemon juice – Enhances brightness and reinforces the citrus notes of the sumac.
1 teaspoon sea salt – Draws out moisture from the onions and balances acidity.
½ teaspoon freshly ground black pepper – Adds gentle heat and depth.

Fresh Herbs

¼ cup fresh parsley, finely chopped – Brings freshness, herbal aroma, and color contrast.

Step-by-Step Instructions

Prepare the Onions
Peel the red onions, halve them lengthwise, and slice into thin wedges approximately ¼ inch thick. Separate the layers gently in a large mixing bowl to increase surface area for seasoning.

Coat with Sumac
Sprinkle the sumac evenly over the onions and toss gently using clean hands or a large spoon. Allow the sumac to cling to the onion surfaces as it begins drawing out moisture.

Season and Dress
Add the sea salt, black pepper, olive oil, and lemon juice. Toss thoroughly until the onions are evenly coated and glossy.

Add Fresh Herbs
Fold in the chopped parsley with a gentle toss, ensuring even distribution without bruising the herbs.

Rest and Serve
Transfer to a serving bowl and let rest at room temperature for 5–10 minutes. This allows the onions to soften slightly and the flavors to fully integrate before serving.

Recipe Notes & Tips

Onion Mellowing Technique – Soaking sliced onions in cold water for 10 minutes reduces sharpness while preserving crunch.
Sumac Intensity Control – Different brands vary in acidity; start with 2 tablespoons and adjust as needed.
Proper Slicing Matters – Uniform thin wedges ensure even seasoning and a pleasant texture.
Resting Is Essential – A short rest improves flavor integration and softens raw onion bite.
Parsley Timing – Add herbs just before serving if preparing ahead to maintain color and aroma.
Oil Quality Counts – Use high-quality extra virgin olive oil for optimal mouthfeel and flavor.

Creative Variations to Try

Citrus Twist – Replace lemon juice with pomegranate molasses for deeper acidity.

Troubleshooting Common Issues

Too Sharp in Flavor – Soak onions briefly in cold water before seasoning.
Uneven Color Coating – Toss onions thoroughly before adding oil to help sumac adhere.
Watery Salad – Use fresh, firm onions and avoid over-salting early.
Muted Flavor – Add an extra pinch of sumac or a splash of lemon just before serving.

Why This Recipe Works

This recipe relies on controlled maceration rather than cooking to transform raw onions. Salt and sumac draw out moisture, softening the onions while concentrating flavor, while olive oil coats the fibers to create a smoother mouthfeel. The combination of natural onion sugars, citrus acidity, and aromatic herbs produces balance without heaviness. At roughly 120 calories per serving, it delivers intense flavor with minimal energy density.

It’s quick, nutritious, and adaptable, making it a staple for both everyday meals and special occasions.
