Creating Dump and Bake Chicken Tzatziki Rice is simple and enjoyable. Just follow these easy steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Baking Dish: In a large baking dish, spread the uncooked rice evenly across the bottom.
3. Season Chicken: In a small bowl, combine garlic powder, onion powder, oregano, paprika, salt, and black pepper. Rub this spice mixture generously over the chicken breasts.
4. Arrange Chicken: Place the seasoned chicken breasts on top of the rice in the baking dish.
5. Add Liquid: Pour the chicken broth over the rice and chicken, ensuring the rice is submerged.
6. Cover and Bake: Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45-50 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
7. Prepare Tzatziki: While the chicken bakes, mix together the diced cucumber, Greek yogurt, lemon juice, and dill in a small bowl for the tzatziki sauce. Add salt to taste.
8. Rest and Fluff: Once the chicken is fully cooked, remove it from the oven and let it rest, covered, for 5 minutes. Fluff the rice with a fork before serving.
9. Serve Chicken: Serve the baked chicken on top of the fluffy rice along with a generous dollop of tzatziki sauce.
