The vibrant mix of sumac-infused red onions creates a lively, cool salad through a basic but wonder-working prep method. This classic Turkish offering turns ordinary onions into a tangy topping that adds life to any meal with its ideal mix of lemony sumac, garden-fresh herbs, and soft onions. Every mouthful gives you an explosion of taste that turns this into much more than onion salad - it's a must-have companion for your mezze table or barbecue dinner.

I first tasted this while wandering around Istanbul and have made it tons of times since. What really won me over was seeing my daughter, who usually avoids spicy stuff, go back for more and say these onions were 'really tasty!'

Key Components and Shopping Advice

  • Red Onions: Go for solid, weighty ones with snug, glossy skin for top results. Red onions offer gorgeous color and just the right mix of sweet and sharp.
  • Sumac: Try to find fresh, vivid wine-colored sumac with a citrusy aroma. You'll usually get the most aromatic kinds at Middle Eastern stores.
  • Fresh Parsley: Pick flat-leaf parsley with bright green leaves and firm stems. Its bold taste works perfectly against the onions.
  • Extra Virgin Olive Oil: Grab a good quality olive oil with a sweet, gentle taste for the best outcome.

Step-by-Step Cooking Guide

Onion Preparation:
Grab a sharp knife or mandoline to cut onions super thin, so they soak up flavor evenly. Slice with the grain for the prettiest look.
Sumac Massage:
Dust sliced onions well with sumac and a tiny bit of salt. Rub softly for 2-3 minutes to soften them up and let the flavor sink in.
Resting Period:
Set the onions aside for 10-15 minutes. They'll release their juices and get a nice tender feel during this time.
Final Seasoning:
Pour olive oil and fresh lemon juice over onions, then mix softly to cover everything. Toss in freshly cut parsley right before you serve.

Once during a hot night, I watched as my Turkish friend made this salad for her family get-together. She taught me that onions should be just see-through enough to read through - now that's how I always check if I've cut them right.

Smart Cooking Tricks

  • Drop onion slices in icy water for 10 minutes before adding seasoning to cut down on their bite while keeping them crisp.
  • Try mixing in other fresh herbs like mint for a cool feeling or dill for more aroma.
  • Don't throw away the onion juice that gathers at the bowl bottom - it works great in salad dressings.

This sumac onion mix shows how careful handling can turn basic stuff into something amazing. Whether it's part of your mezze spread or topping your grilled meats, this dish brings strong, fresh flavors that wake up your taste buds and make any meal extra special.

Ingredients

→ Core Ingredients

01 1 tablespoon fresh parsley, finely chopped
02 1 large red onion, sliced thin
03 1 tablespoon extra virgin olive oil
04 1 tablespoon red wine vinegar or lemon juice
05 1/2 teaspoon salt
06 2 teaspoons sumac

Instructions

Step 01

In a mixing bowl, toss the thin onion slices with salt and sumac. Now it’s time to get your hands in there! Gently press and rub the spices into the onions for just under a minute until fully coated.

Step 02

Drizzle in olive oil and vinegar, then mix in the chopped parsley. Stir it up, cover it, and let it sit for at least 20 minutes so everything blends nicely.

Step 03

These tangy onions are good to go! Pair them with your favorite sandwiches, wraps, burgers, or salads. Planning to save some? Keep them fresh in a sealed container in the fridge for up to four days.

Notes

  1. As time passes, the onions will soften more. If there's extra liquid, drain it before serving.
  2. Want to switch it up? Use fresh mint or cilantro instead of parsley.
  3. Yellow or white onions can work too, but add a tiny bit of sugar since they’re not naturally as sweet as red onions.

Tools You'll Need

  • A medium-sized bowl for mixing
  • Sealable container for refrigeration
