Ingredients
To make this flavorful tray bake, here’s what you’ll need:
For the chicken and vegetables:
- 1.5 lbs (700g) chicken breast or thighs, cut into bite-sized pieces
- 2 bell peppers, diced (use a mix of colors for vibrancy)
- 1 red onion, cut into chunks
- 3 tbsp olive oil
- 1 cup cherry tomatoes
- 2 tsp dried oregano
- 1 tsp smoked paprika
- 1/2 tsp ground cumin
- 3 garlic cloves, minced
- Juice of 1 lemon
- Salt and pepper, to taste
For the tzatziki sauce:
- 1 cup Greek yogurt
- 1/2 cucumber, grated and squeezed to remove excess liquid
- 1 garlic clove, minced
- 1 tbsp olive oil
- 1 tbsp fresh dill or parsley, finely chopped
- Juice of 1/2 lemon
- Salt, to taste
To serve:
- Flatbreads, warmed
- Fresh parsley, chopped, for garnish
Instructions
- Marinate the chicken:
In a large bowl, combine the chicken pieces, olive oil, oregano, smoked paprika, cumin, garlic, lemon juice, salt, and pepper. Mix well to coat the chicken evenly. Let it marinate for at least 20 minutes (or up to overnight in the fridge for maximum flavor). - Prepare the vegetables:
Toss the bell peppers, red onion, and cherry tomatoes with a drizzle of olive oil, a pinch of salt, and some dried oregano. - Assemble the tray bake:
Preheat your oven to 400°F (200°C). Spread the marinated chicken and prepared vegetables evenly across a large baking dish or tray. - Roast to perfection:
Bake for 25–30 minutes, stirring halfway through, until the chicken is cooked through and the vegetables are tender and slightly caramelized. - Make the tzatziki:
While the tray bake is cooking, prepare the tzatziki. In a bowl, mix the Greek yogurt, grated cucumber, garlic, olive oil, lemon juice, and fresh dill or parsley. Season with salt to taste. Refrigerate until ready to serve. - Serve and garnish:
Remove the tray bake from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley. Serve warm with flatbreads and a generous dollop of tzatziki on the side.
