Sheet-Pan Chicken Souvlaki with Peppers and Onion

Jump to Recipe

Sheet-pan chicken souvlaki takes the classic Greek skewers and turns them into one easy pan of roasted chicken, peppers, and onion. No skewers, no grill, just a hot oven and a good lemon-garlic marinade.

The chicken comes out juicy with charred edges from the high oven heat. The peppers and onion roast alongside and pick up the same marinade, so every bite has that garlicky, lemony flavor.

I like this recipe for weeknights because the prep is short and the pan does most of the work. Marinate the chicken while you chop the vegetables, then let the oven finish dinner.

Serve it with warm pita, a scoop of tzatziki, and a squeeze of fresh lemon. It’s simple food that doesn’t need much fuss.

Why You’ll Love This Recipe

  • One sheet pan means less cleanup than skewers on a grill
  • Marinade doubles as flavor for the chicken and vegetables
  • Ready in about an hour including marinating time
  • Leftovers reheat well for lunch the next day

Ingredient Notes

  • chicken thighs: Boneless, skinless thighs stay juicy at high heat. Chicken breast works too, but cut it a little smaller so it cooks through at the same rate as the thighs.
  • lemon juice: Use fresh lemon, not bottled. It gives the marinade a brighter, less sharp taste.
  • dried oregano: Greek oregano has a stronger, slightly minty flavor. Regular dried oregano from the spice aisle works fine too.
  • red wine vinegar: Adds tang on top of the lemon. You can leave it out if you don’t have it, the lemon juice still does most of the work.
  • bell peppers: I use one red and one yellow for color, but any color works. Cut them the same size as the chicken so they cook evenly.
  • red onion: Cut into wedges so the layers stay together on the pan instead of falling apart into thin rings.
  • cherry tomatoes: Optional, but they add a juicy pop. Add them in the last 5 minutes so they don’t turn mushy.

Ingredients
  

Marinade
  • 3 tbsp olive oil
  • 3 tbsp lemon juice about 1 large lemon
  • 4 garlic cloves minced
  • 2 tsp dried oregano
  • 1 tbsp red wine vinegar
  • 1 tsp salt
  • 1/2 tsp black pepper
Sheet Pan
  • 700 g chicken thighs, boneless skinless cut into 1.5-inch cubes
  • 2 bell peppers cut into 1.5-inch pieces
  • 1 red onion large; cut into wedges
  • 1 cup cherry tomatoes optional
  • 1 tbsp olive oil for tossing vegetables
To Serve
  • 4 pita bread warmed
  • 1 cup tzatziki
  • 2 tbsp fresh parsley chopped
  • 4 lemon wedges

Method
 

Marinate the Chicken
  1. In a large mixing bowl, whisk the olive oil, lemon juice, garlic, oregano, red wine vinegar, salt, and pepper until combined.
  2. Add the chicken cubes and toss until every piece is coated. Cover and marinate in the fridge for at least 30 minutes, up to 4 hours.
Roast
  1. Heat the oven to 220C / 425F and line a sheet pan 33 x 46 cm / 13 x 18 inch with parchment paper.
  2. Toss the bell peppers and red onion with 1 tbsp olive oil and a pinch of salt directly on the pan.
  3. Lift the chicken from the marinade and arrange it among the vegetables in a single layer, leaving space between pieces so everything roasts instead of steams. Discard the leftover marinade.
  4. Roast for 15 minutes, then stir everything and flip the chicken pieces.
  5. If using cherry tomatoes, scatter them over the pan now. Continue roasting for 5 to 10 minutes, until the chicken reaches 165F / 74C on an instant-read thermometer and the vegetables have charred edges.
Finish and Serve
  1. Remove the pan from the oven and squeeze fresh lemon juice over the chicken and vegetables.
  2. Sprinkle with chopped parsley and serve straight from the pan with warm pita, tzatziki, and extra lemon wedges.

Notes

  • Pat the chicken dry before marinating so the marinade coats it better.
  • Don't skip the resting bowl step, tossing everything together evenly matters more than exact timing.
  • Cut vegetables the same size as the chicken cubes for even roasting.
  • Line the sheet pan with parchment for easier cleanup, the marinade can stick and burn on bare metal.

Tips for Success

  • Cut the chicken into even 1.5-inch cubes so every piece cooks through at the same time.
  • Marinate for at least 30 minutes, but don’t go past 4 hours or the lemon starts to make the texture mushy.
  • Spread the chicken and vegetables in a single layer with space between pieces so they roast instead of steam.
  • Check the chicken with an instant-read thermometer at the 20 minute mark, it’s done at 165F/74C.
  • Save a spoonful of raw marinade before adding the chicken if you want extra sauce to drizzle at the end.

Variations

  • Swap the chicken thighs for cubed pork shoulder and add 5 minutes to the roasting time for a pork souvlaki version.
  • Add sliced zucchini or mushrooms to the pan in the last 15 minutes for more roasted vegetables.
  • Skip the pita and serve everything over warm rice or a bed of shredded lettuce for a lighter bowl.

Storage and Reheating

Sheet-pan chicken souvlaki keeps in an airtight container in the fridge for 3 to 4 days. The chicken and vegetables hold their flavor well since everything is already roasted together.

To reheat, spread the chicken and vegetables on a sheet pan and warm in the oven at 175C/350F for 8 to 10 minutes, until heated through. A skillet over medium heat for 4 to 5 minutes works too and keeps some char on the edges.

I don’t recommend the microwave for this one, it makes the peppers go soft and watery. The oven or skillet keeps the texture closer to fresh.

Serving Suggestions

Warm pita bread and a bowl of tzatziki are the easiest way to serve this. Pile the chicken and vegetables into the pita, add a spoonful of tzatziki, and fold it up like a wrap.

A simple Cypriot village salad with fresh halloumi rounds out the plate without much extra cooking. Lemon rice or a pile of creamy lemon orzo with feta also works if you want something more filling.

For a lighter meal, skip the bread and serve the chicken and peppers over shredded romaine with a drizzle of olive oil and extra lemon juice.

FAQ

How do I know when sheet-pan chicken souvlaki is done roasting?

The chicken is done when it hits 165F/74C in the thickest piece and the edges of the peppers and onion look lightly charred. This usually takes 20 to 25 minutes at 220C/425F. Check with an instant-read thermometer in a couple of the larger chicken cubes to be sure, since pan hot spots can cook pieces unevenly.

Can I use chicken breast instead of thighs for this souvlaki?

Yes, chicken breast works fine, just cut it into slightly smaller cubes since breast meat dries out faster than thigh. Check the temperature a few minutes early, breast often reaches 165F/74C closer to the 18 minute mark instead of 20 to 25 minutes.

Can I marinate the chicken overnight before making this souvlaki?

You can marinate up to 4 hours, but I wouldn’t go overnight. The lemon juice and vinegar start to break down the chicken texture after several hours, making it a bit mushy instead of tender. If you need to prep ahead, mix the marinade the night before and add the chicken in the morning.

What goes with sheet-pan chicken souvlaki besides pita?

Lemon rice, orzo, or a simple Greek salad with cucumber and feta all pair well with this dish. Tzatziki is the classic sauce, but a garlicky yogurt dip or plain hummus works too if you don’t have the ingredients for tzatziki on hand.

Is this sheet-pan chicken souvlaki gluten-free?

Yes, the chicken, marinade, and vegetables are all naturally gluten-free on their own. The only thing to watch is the pita bread on the side, so swap in a gluten-free pita or serve the chicken over rice instead if that’s a concern.

What’s the difference between this and traditional skewered souvlaki?

Traditional souvlaki is threaded onto skewers and grilled over an open flame, which gives a smokier char. This sheet-pan version uses the same lemon-garlic marinade but roasts in the oven like this Cypriot chicken and potato tray bake, so it’s less smoky but a lot easier for a weeknight without firing up a grill.
