Creating Greek Chicken Casserole involves a few simple steps that ensure delicious results. Follow these instructions for a delightful experience:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).

2. Prepare Chicken: Cut the chicken breasts into bite-sized pieces. Season them with salt, pepper, oregano, and thyme.

3. Sauté Vegetables: In a large skillet over medium heat, add olive oil. Stir in the onions and garlic, sautéing until fragrant, about 2-3 minutes.

4. Cook Chicken: Add the seasoned chicken pieces to the skillet and cook until they are browned and cooked through, roughly 6-8 minutes.

5. Combine Ingredients: In a large mixing bowl, combine the cooked orzo, diced tomatoes, bell pepper, feta cheese, olives, and the chicken mixture. Stir until everything is well incorporated.

6. Add Chicken Broth: Pour in the chicken broth and mix again, ensuring the ingredients are evenly coated with the broth.

7. Transfer to Casserole Dish: Grease a 9×13 inch baking dish and transfer the combined mixture into the dish. Spread it evenly across the surface.

8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until heated through and the top is slightly golden.

9. Garnish: Once baked, remove from the oven and let it rest for a few minutes. Garnish with fresh parsley or basil before serving.

10. Serve and Enjoy: Dish out portions, making sure to include a generous serving of the casserole’s hearty mixture.
