Creating this Dump-and-Bake Chicken Tzatziki with Rice is easy when you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare the Baking Dish: Lightly grease a large baking dish with cooking spray or olive oil.
3. Layer the Chicken: Place the boneless, skinless chicken breasts in the center of the baking dish. Season with salt, pepper, garlic powder, onion powder, and paprika.
4. Add Rice: Sprinkle the basmati rice evenly around the chicken in the dish.
5. Pour in Broth: Carefully pour the chicken broth over the rice and chicken, ensuring the rice is submerged.
6. Cover with Foil: Tightly cover the baking dish with aluminum foil to trap moisture.
7. Bake: Place the dish in the preheated oven and bake for 25-30 minutes.
8. Prepare Tzatziki: While the chicken and rice are baking, mix the Greek yogurt, diced cucumber, chopped dill, and a pinch of salt in a bowl to create your tzatziki sauce.
9. Check for Doneness: After 30 minutes, remove the foil and check if the chicken is cooked through. If needed, bake for an additional 5-10 minutes until the chicken reaches an internal temperature of 165°F (75°C).
10. Rest and Fluff: Once cooked, let the dish rest for about 5 minutes. Fluff the rice with a fork and mix it with the juices from the chicken.
11. Serve with Tzatziki: Serve the chicken and rice hot, topped with a generous dollop of tzatziki sauce.
