Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or similar casserole dish to prevent sticking.

2. Add the Rice

Pour the uncooked white rice into the prepared baking dish and spread it evenly across the bottom.

3. Add the Broth

Carefully pour the chicken broth over the rice, making sure the rice is fully submerged. This ensures even cooking and tender texture.

4. Add the Chicken

Evenly distribute the cooked chicken over the rice layer. Spread it out so every portion gets balanced protein.

5. Layer the Vegetables

Scatter the diced cucumber, chopped red onion, halved grape tomatoes, and sliced Kalamata olives evenly over the chicken.

6. Mix the Sauce

In a bowl, combine the tzatziki sauce, garlic powder, dried oregano, salt, and pepper. Stir until smooth and well mixed.

7. Add the Sauce

Spread the tzatziki mixture evenly over the vegetables and chicken, ensuring everything is lightly coated.

8. Add the Feta

Sprinkle the crumbled feta cheese evenly across the top of the casserole.

9. Cover and Bake

Cover the dish tightly with aluminum foil and bake for 45 minutes, or until the rice is cooked and the chicken is heated through.

10. Uncover and Finish Baking

Remove the foil and return the dish to the oven. Bake for an additional 10 minutes, until the feta cheese is slightly golden.

11. Rest and Garnish

Remove the casserole from the oven and allow it to rest for 5 minutes. Garnish with fresh chopped parsley before serving.
