How to Make Dump-and-Bake Chicken Tzatziki Casserole

Creating this casserole is simple. Follow these straightforward steps to whip it up effortlessly:

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Assemble the Base: Spread the uncooked long-grain white rice evenly across the bottom of the baking dish. Pour in the chicken broth, ensuring the rice is adequately submerged.
  3. Add the Chicken: Distribute the bite-sized chicken pieces evenly over the rice. This allows the flavors to meld while cooking.
  4. Sprinkle with Spices: Evenly sprinkle the garlic powder, onion powder, dried oregano, and paprika over the chicken for a delicious flavor boost.
  5. Top with Tzatziki Sauce: Generously spoon the tzatziki sauce over the chicken, gently spreading it to coat. This keeps the chicken moist and adds creaminess.
  6. Bake: Cover the dish tightly with aluminum foil and bake for 35-40 minutes, or until the chicken is cooked through and the rice is tender. If a drier texture is desired, remove the foil for the last 5-10 minutes.
  7. Finish with Garnishes: Once cooked, let it sit for about 5 minutes before garnishing with crumbled feta, fresh herbs, and cucumber slices.

Once finished, serve this gorgeous casserole warm, and savor every flavorful bite. Not only does it look appealing, but it also fills your kitchen with tantalizing Mediterranean aromas.
