Creating your Dump-and-Bake Chicken Tzatziki Rice is a breeze when you follow these simple steps:

1. Preheat Your Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Baking Dish: In a large baking dish, spread the uncooked rice evenly across the bottom.
3. Add Chicken Broth: Pour the chicken broth over the rice, ensuring it is evenly distributed.
4. Season the Chicken: In a bowl, season the chicken breasts with garlic powder, onion powder, salt, and black pepper.
5. Arrange the Chicken: Place the seasoned chicken breasts on top of the rice, ensuring they are evenly spaced.
6. Add Tzatziki Sauce: Spoon the tzatziki sauce over the chicken breasts, covering them generously.
7. Optional Vegetables: Scatter the halved cherry tomatoes around the chicken for added flavor and color.
8. Cover and Bake: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 45-50 minutes.
9. Check for Doneness: After 45 minutes, check the chicken for doneness. It should reach an internal temperature of 165°F (74°C).
10. Rest the Dish: Once cooked, remove the dish from the oven and let it rest, covered, for 5-10 minutes to allow the rice to absorb the flavors.
11. Garnish: Before serving, garnish with diced cucumber and fresh dill or parsley for a refreshing touch.

These straightforward steps ensure that your Dump-and-Bake Chicken Tzatziki Rice comes out perfectly every time.
