Description

Dump-and-Bake Chicken Tzatziki Casserole is an easy, one-pan Mediterranean-inspired dish with tender chicken, creamy tzatziki, vegetables, and rice baked together for a flavorful and comforting meal.


Ingredients

  • 1.5 lbs boneless, skinless chicken breast or thighs, cut into chunks
  • 1 cup uncooked white rice
  • 1.75 cups chicken broth or water
  • 1 cup cherry tomatoes, halved
  • 1/2 red onion, thinly sliced
  • 1 zucchini or cucumber, chopped (remove seeds if using cucumber)
  • 1 tsp garlic powder
  • 1 tsp dried oregano
  • Salt and pepper to taste
  • 1.25 cups tzatziki sauce, divided
  • 1/2 cup crumbled feta cheese
  • Fresh dill or parsley for garnish (optional)

Instructions

  1. Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
  2. In the dish, mix uncooked rice with chicken broth, garlic powder, oregano, salt, and pepper.
  3. Add chicken, cherry tomatoes, red onion, and zucchini (or cucumber) and stir to combine.
  4. Add half of the tzatziki sauce and mix everything directly in the baking dish.
  5. Cover tightly with foil and bake for 45–50 minutes, until chicken is cooked and rice is tender.
  6. Remove foil, dollop or spread remaining tzatziki sauce on top, and sprinkle with crumbled feta.
  7. Bake uncovered for another 5–10 minutes until bubbly and lightly golden.
  8. Garnish with chopped dill or parsley before serving, if desired.

Notes

  • Use thick tzatziki sauce for best texture.
  • Cucumber works but zucchini holds up better in the oven.
  • Swap rice for orzo, quinoa, or cauliflower rice (adjust liquid accordingly).
  • Add olives or spinach for extra Mediterranean flavor.
  • Add a splash of broth when reheating if the casserole looks dry.
