Bring authentic Greek street-food flavors to your kitchen with Sheet Pan Chicken Souvlaki with Red Onion. Tender chicken pieces are marinated in extra virgin olive oil, lemon juice, garlic, and wild oregano, then roasted alongside thick wedges of red onion and cherry tomatoes until charred and bursting with flavor.
The secret to juicy souvlaki with crispy edges is Roasting at High Heat (425°F / 220°C) and Cutting the Red Onion into Thick Wedges. Leaving the onion root intact keeps the wedges together so they sweeten and char on the edges without turning to mush alongside the chicken.

Step-by-Step Instructions
1.Prep Oven & Sheet Pan:3 min.
Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper or heavy-duty aluminum foil.
2.Whisk Marinade & Coat Chicken:5 min.
In a bowl, whisk together ¼ cup olive oil, lemon juice, lemon zest, garlic, oregano, red wine vinegar, salt, and pepper. Add 1½ lbs diced chicken thighs and toss until well coated (marinate for 15 minutes if time permits).
3.Arrange Sheet Pan:3 min.
Spread the marinated chicken, red onion wedges, and cherry tomatoes evenly across the prepared sheet pan in a single layer. Drizzle any remaining marinade from the bowl over the onions and tomatoes.
4.High-Heat Roast:18 min.
Roast at 425°F (220°C) for 15 to 18 minutes until the chicken reaches an internal temperature of 165°F (74°C) and the red onions are sweet with charred edges. (Optional: Broil for 2 minutes at the end for extra browning).
5.Garnish & Serve Warm:1 min.
Remove from the oven, squeeze fresh lemon juice over the top, and sprinkle with fresh parsley and crumbled feta. Serve immediately with warm pitas and tzatziki!
Expert Tips for Success
- Prefer Thighs over Breasts: Chicken thighs stay far juicier at high oven temperatures than chicken breasts, mimicking the succulence of traditional grilled souvlaki.
- Keep Onion Wedges Thick: Cutting red onions into ½-inch wedges keeps them structurally intact so they caramelize and char rather than burn.
- High Heat is Essential: Roasting at 425°F (220°C) ensures the chicken cooks through quickly without drying out, while giving the tomatoes and onions great color.
