Description

A bright, no-fuss casserole that layers tender chicken, raw rice, fresh veggies and tangy tzatziki, then bakes into a single, satisfying meal. Perfect for nights when you want flavor without fuss.


Ingredients

Scale
  • 2 cups cooked chicken, shredded or chopped
  • 1 cup uncooked long-grain white rice
  • 2 cups low-sodium chicken broth
  • 1 cup cucumber, small dice
  • 1/2 cup red onion, finely minced
  • 1 cup grape or cherry tomatoes, halved
  • 1/2 cup Kalamata olives, pitted and sliced
  • 1 cup Greek-style tzatziki sauce (store-bought or homemade)
  • 1 tsp garlic powder
  • 1 tsp dried oregano
  • Salt and freshly ground black pepper, to taste
  • 1 cup crumbled feta cheese
  • 2 tbsp fresh parsley, chopped (for finishing)


Instructions

  1. Preheat the oven to 375°F (190°C). Lightly oil or spray a 9×13-inch baking pan.
  2. Pour the uncooked rice into the bottom of the dish and spread it into an even layer.
  3. Pour the chicken broth over the rice so the grains sit submerged. This is the liquid that will cook the rice — don’t skimp. Bold tip: make sure the rice is covered.
  4. Scatter the cooked chicken evenly over the rice so every bite has protein.
  5. Top the chicken with the diced cucumber, chopped red onion, halved tomatoes, and sliced Kalamata olives. Distribute the vegetables so they’re fairly even across the pan.
  6. In a small bowl, stir together the tzatziki, garlic powder, oregano, salt and pepper until smooth.
  7. Spoon and spread the seasoned tzatziki over the vegetables and chicken, covering the surface.
  8. Sprinkle the crumbled feta across the top in an even layer.
  9. Cover the casserole tightly with aluminum foil and bake for 45 minutes, or until the rice has absorbed the liquid and appears tender.
  10. Remove the foil and bake another 8–12 minutes until the feta takes on a light golden color and the edges crisp slightly.
  11. Let the dish sit for 5 minutes, then scatter chopped parsley over the top and serve.

Notes

  • Notes & swaps
    • Marinate option: For more punch, toss the chicken in lemon juice, olive oil and oregano for 15–30 minutes before assembling.
    • Brown rice: Swap for brown rice if you like — add 10–15 minutes and about 1/2 cup extra broth.
    • No tzatziki? Use plain Greek yogurt, grated cucumber (squeeze out excess moisture), garlic and dill to mimic tzatziki.
    • Serving idea: Warm pita or flatbread pairs perfectly for scooping.
    • Make-ahead: Assemble through step 8, cover and refrigerate overnight. Bake straight from the fridge, adding ~5–10 extra minutes.
    • Storage: Refrigerate leftovers up to 4 days or freeze portions for up to 2 months.
  • FYI: If the rice looks underdone when you peek, add a splash of hot broth, re-cover and give it more time.
  • Quick tips for success
    • Use cooked chicken (rotisserie is a great shortcut).
    • Spread rice in one uniform layer to ensure even cooking.
    • Keep the casserole covered while baking so the steam cooks the rice through.
    • Rest briefly before serving so the casserole sets and slices cleanly.
