Sumac Onions

By Lee Jackson ↣ Published on: October 19, 2019

Sometimes the simplest salads pack the most flavour. This easy sumac onions recipe is bright, tangy and slightly sweet — a perfect accompaniment for bread, grilled meats, fish and many Mediterranean dishes. It’s quick to make and refreshes richer plates beautifully.

Part salad and part condiment, red onion tossed with sumac is a staple on Turkish, Middle Eastern and Mediterranean tables. Its sharp, citrusy notes cut through rich meats and oily fish, giving dishes a clean, lively finish. Think of it as a fresher, quicker cousin to pickled onions.

This recipe celebrates fresh ingredients and bright regional flavours, perfect alongside grilled meats, kebabs and roasted vegetables.

For me, it brings back memories of Istanbul, where I spooned it over everything from mackerel to kofta and grilled lamb. It’s unfussy, versatile and incredibly easy to make at home.

What’s Ahead?

What is Sumac?

Sumac is a tangy, aromatic spice made from dried, crushed sumac berries. It adds a bright, lemony acidity to dishes and is common in Turkish, Middle Eastern and Mediterranean cooking. Use it to season salads, marinades and roasted meats for a citrusy lift.

Why it works?

Freshness: The sharp, citrusy notes of sumac brighten onions and lift heavier dishes like lamb or oily fish.

Speed: This salad takes about 15 minutes to prepare — quick, simple and effective.

Stuff You’ll Need

Only a handful of ingredients are required to make sumac onions. Here’s a concise list:

• Red onion — mild and slightly sweet, it works best thinly sliced.
• Sumac — the key spice; its tangy, lemony flavour defines the salad.
• Lemon — juice adds freshness and a pickling brightness.
• Garlic — a small clove, minced to add depth.
• Extra virgin olive oil — a splash of good oil brings everything together.
• Parsley & mint — finely chopped, they add a fresh, aromatic finish.

Step by Step

This recipe is straightforward. Salting the onions and then rinsing them mellows their bite, while using your hands to mix helps the sumac colour and flavour the slices evenly.

1. Step 1 — Peel the onion, halve it and slice into thin half-moons. Sprinkle with 1 tsp salt, toss and leave in a colander for about 10 minutes. Rinse well, then pat dry with paper towels.
2. Step 2 — Combine the drained onion with 2 tbsp sumac, the juice of 1 lemon, 1 small minced garlic clove, 1 tbsp extra virgin olive oil and the chopped parsley and mint. Use your hands or a spoon to mix gently until everything is evenly coated.

Let the mixture rest for at least 15 minutes to let the flavours meld before serving.

Serving & Storage Suggestions

• Serving — Offer as a small salad or condiment alongside grilled meats, kebabs, roasted vegetables or fish. It works well in flatbreads or as a bright garnish on richer plates.
• Storage — Store in a covered container in the refrigerator for 4–5 days. The salad does not freeze well.
