Chicken Shawarma Skewers with Toum and Sumac Onions

Chicken skewers might be the most underrated thing you can put on the grill. Not when they turn out dry, pale and sad, of course, because then they’re mostly a reminder of why people lose patience with poultry. But when they’re made with boneless thighs, get a generous coating of spices and are grilled with a bit of feel for heat zones, they suddenly become exactly the kind of food you want to eat with your hands while the next batch is still sitting on the grate.

This version heads in a shawarma direction with cumin, paprika, cinnamon, lemon and garlic, but it still feels completely at home on Swedish grilling ground. Toum, that is fluffy garlic cream, brings coolness and a bite at the same time, while the sumac onions add tangy freshness. The result is a recipe that feels generous, a little messy in the good way and very hard to stop at just one portion.

The Recipe in Brief

This is a chicken skewer recipe where the flavor comes from a yogurt-based shawarma marinade, but the juiciness comes from using boneless chicken thighs instead of breast. Thighs handle the grill better, stay juicier and get a nicer surface once the sugar in the marinade starts to take on color.

The idea is to serve it as a whole meal: skewers, toum, sumac onions and preferably warm bread or flatbread from the grill. It’s exactly the kind of recipe that works just as well on a weeknight with a bit of ambition as on a weekend when you want to put out something people will actually talk about while they eat.

Why You Should Try This Recipe

• Boneless chicken thighs make juicier skewers than chicken breast.
• The marinade gives deep spiciness without turning heavy or sugary.
• Toum and sumac onions make the whole dish feel finished, not just grilled protein on a stick.
• The two-zone method makes it easier to get color without burning the marinade.
• The recipe is easy to scale up if you’re grilling for a crowd.

Ingredients

For the chicken skewers

• 2 lb boneless chicken thighs
• ¾ cup + 1½ tbsp Greek yogurt
• 2 tbsp olive oil
• 2 garlic cloves, finely grated
• 1 ½ tbsp lemon juice
• 2 tsp ground cumin
• 2 tsp paprika
• 1 tsp ground coriander
• 1 tsp onion powder
• ½ tsp ground cinnamon
• ½ tsp chili flakes
• 1 ½ tsp salt
• ½ tsp black pepper

For the toum (simplified garlic cream)

• 1 egg white
• 2 garlic cloves
• 1 tbsp lemon juice
• 1 tsp cold water
• ¾ cup + 1½ tbsp neutral oil
• ¼ tsp salt

For the sumac onions

• 1 red onion, thinly sliced
• 1 tbsp lemon juice
• 1 tsp sumac
• ¼ tsp salt

For serving

• 0 thin pita or lavash breads
• 1 small cucumber, diced
• 2 tomatoes, diced
• 1 handful of parsley, coarsely chopped

Instructions

1. Cut the boneless chicken thighs into pieces that are a good size for skewers, roughly 4 x 1 ½ in. Trim off any larger clumps of fat, but it's fine to leave a little for juiciness.
2. Mix the yogurt, olive oil, garlic, lemon juice and all the spices into the marinade. Fold in the chicken and let it sit for at least 2 h, preferably overnight.
3. Mix the red onion with lemon juice, sumac and salt. Massage lightly with your hands and let it sit while you prepare the rest.
4. Make the toum by blending the egg white, garlic, lemon juice, water and salt. Add the oil in a thin stream until you get a white, fluffy and fairly firm cream. Chill it.
5. Thread the chicken onto metal skewers or soaked wooden skewers. Shake off excess marinade so it doesn't drip too much over the coals.
6. Light the grill for two-zone grilling with a hot direct zone and a cooler zone next to it. Aim for medium-high to high heat over the direct part.
7. Place the skewers over direct heat first and grill 2 min–3 min per side until they get clear color. Then move them to the cooler zone if they need to finish cooking without darkening too much.
8. Grill until the chicken has reached 162°F in the thickest part. Warm the bread briefly on the grill during the last minute.
9. Serve the skewers right away with toum, sumac onions, cucumber, tomato, parsley and warm bread.

Grilling Method: How to Get It Right on the Grill

Chicken skewers are a perfect example of why two heat zones are such a good habit. The marinade contains yogurt, spices and a little acid. That’s great for flavor and surface, but not for sitting long over brutal glowing coals. So start with color over direct heat, then give the skewers some calmer residual heat if they need a few more minutes.

On a Weber 57 or another kettle grill, you pile the coals on one side. On a gas grill, you light two burners and leave one cooler area. Keep the lid closed between turns and you get more even heat around the whole skewer. It also lowers the risk of panic-flipping the chicken every thirty seconds just because it looks dramatic.

Don’t wipe off too much of the marinade, but don’t let big clumps hang on either. They’ll drip into the coals and give you sooty bitterness instead of a good grilled surface.

If you want to feel more confident about moving the skewers between the hot and the cool zone on the grill, BBQLovers’ guide to grilling methods is a good next step.

Temperature, Time and Signs That It’s Done

• Grill temperature: medium-high to high direct heat with a cool zone next to it
• Time over direct heat: about 6 min–8 min in total
• Any extra time over indirect heat or a cooler zone: 3 min–5 min
• Target temperature in the chicken: 162°F

The chicken is done when the meat is cooked through but still juicy and the surface has clear dark edges without being burnt. The juices should run clear, but you’re still best off working with a thermometer. It’s cheap insurance against both dry chicken and unnecessary uncertainty.

Which Grill Works Best?

A regular kettle grill is almost ideal here because the skewers get nice color quickly and you can easily slide them a few centimeters to the side when you want to calm the heat down. A gas grill is also very rewarding, especially if you’re making lots of skewers and want to keep an even pace. A kamado works well but can feel like a bit too much machinery for this kind of quick, lively grilling.

Whichever grill you use, the same basic rule applies: build a hot side and a safe side. That’s where the juiciness is saved.

Serving Suggestions

I think these skewers are at their best when you put everything in the middle of the table and let people build their own. Put the skewers on a platter, dollop toum into a bowl, pile on the sumac onions and set out warm bread together with tomato, cucumber and parsley. That gives you both the grill feel and that slightly sloppy, generous mood this food deserves.

If you want to make it more filling, you can add grilled pointed cabbage, roasted potatoes or a simple bulgur salad. But don’t be afraid of simplicity either. When the skewers are juicy and the toum has the right bite, it doesn’t take much more to make it feel complete.

If you’re craving even more chicken from the grill in a completely different style, BBQLovers’ recipe for pulled chicken is also well worth trying.

Björn’s Tips

• Boneless chicken thighs beat breast on a skewer every time if you want some margin for error on the grill.
• Let the skewers lie still a bit longer than you think before the first turn. That’s how the surface gets time to set.
• Make the toum well in advance. It only gets better from standing cold for a while.

Common Mistakes

• Using chicken breast and then being surprised that the skewers feel dry.
• Letting too much marinade drip into the coals so the chicken gets a bitter, sooty surface.
• Running full heat the whole way instead of moving the skewers when needed.
• Not measuring the temperature in the thickest skewer.
• Forgetting something cold and tangy for serving, which makes the flavor feel heavier than it has to.

Variations and Adjustments

If you want more heat, you can increase the chili flakes or add a little Aleppo pepper. For an even clearer grilled flavor, you can give the skewers a light brush of melted butter just as they come off the grill. You can also swap the pita bread for lettuce leaves if you want a lighter serving, or add grilled bell pepper for more sweetness.

If you don’t want to make toum, you can serve a cold yogurt-based garlic sauce instead, but it’s really the fluffy garlic cream that does a lot for the whole dish. It’s strong, creamy and very kind to grilled chicken.

Why This Recipe Works

Boneless chicken thigh contains more fat and connective tissue than breast, which means it stays juicier when exposed to hard grill heat. The yogurt in the marinade helps the spices stick and adds a mild acidity that rounds off the flavor without making the meat mushy. The spice mix builds warmth, sweetness and earthiness, but still leaves room for the grill flavor itself.

Toum and sumac onions provide two important contrasts. Toum contributes fat, coolness and aggressive garlic in a wonderful way, while the sumac gives a tangy fruitiness that cuts through both the chicken and the cream. When the skewers first get color and then finish more gently, you get both a Maillard crust and a juicy center. That combination is what makes the recipe feel well thought out, not just heavily spiced.

FAQ

Can I use chicken breast instead of boneless thighs?

You can, but you get a much smaller margin for error. Breast gets dry faster and needs more careful grilling.

How long should the chicken marinate?

At least 2 h is good, but overnight gives even more flavor and a more even result.

What internal temperature should chicken skewers reach?

Aim for 162°F in the thickest piece on the skewer.

Can I make the skewers ahead of time?

Yes, you can thread them a few hours ahead and keep them cold. It makes the grilling itself a lot calmer.

What goes well with the skewers if I don’t want bread?

Grilled vegetables, bulgur, roasted potatoes or just a fresh salad of cucumber and tomato all work well.

These are the kind of skewers that disappear faster than you can say the next batch will be ready soon. Quite a good verdict in itself.
