Follow these simple steps to create your Dump and Bake Chicken Tzatziki Rice:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare the Baking Dish: Lightly grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking.
3. Arrange the Chicken: Place the boneless chicken breasts in a single layer at the bottom of the prepared dish.
4. Add Seasonings: Sprinkle the garlic powder, onion powder, oregano, salt, and black pepper evenly over the chicken.
5. Combine Rice and Broth: In a separate bowl, mix the uncooked rice and chicken broth. Pour this mixture over the chicken in the baking dish.
6. Add Tzatziki Sauce: Spread the tzatziki sauce evenly over the chicken and rice mixture.
7. Cover the Dish: Cover the baking dish tightly with aluminum foil to create steam while cooking.
8. Bake: Place the covered dish in the preheated oven and bake for 40-45 minutes or until the chicken is cooked through and the rice is tender.
9. Check Doneness: Ensure the chicken reaches an internal temperature of 165°F (75°C). If not, return it to the oven for additional time.
10. Garnish and Serve: Once done, remove the foil, garnish with chopped cucumber and parsley, and serve with lemon wedges on the side.

With these clear instructions, you’ll find that making Dump and Bake Chicken Tzatziki Rice is incredibly straightforward, even for beginner cooks.
