Ingredients

2 cups cooked chicken, shredded or diced
1 cup uncooked white rice

2 cups chicken broth
1 cup cucumber, diced

1/2 cup red onion, finely chopped
1 cup grape tomatoes, halved

1/2 cup Kalamata olives, pitted and sliced
1 cup Greek-style tzatziki sauce
1 teaspoon garlic powder

1 teaspoon dried oregano
Salt and pepper, to taste
1 cup feta cheese, crumbled

2 tablespoons fresh parsley, chopped for garnish

Instructions

Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or similar casserole dish.
Step 2: In the prepared dish, add the uncooked rice and spread it evenly across the bottom.

Step 3: Pour the chicken broth over the rice, ensuring that the rice is submerged.
Step 4: Evenly distribute the cooked chicken over the rice.
Step 5: Scatter the diced cucumber, chopped red onion, halved grape tomatoes, and sliced Kalamata olives on top of the chicken layer.

Step 6: In a bowl, mix the tzatziki sauce with garlic powder, dried oregano, salt, and pepper.
Step 7: Spread the tzatziki sauce mixture evenly over the vegetables and chicken, ensuring everything is covered.
Step 8: Sprinkle the crumbled feta cheese across the top.

Step 9: Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes, or until the rice is cooked and the chicken is heated through.
Step 10: Remove the foil and bake for an additional 10 minutes, or until the feta cheese is slightly golden.
Step 11: Let the casserole cool for a few minutes, then garnish with chopped fresh parsley before serving.

Tips & Variations

Use rotisserie chicken to save time and add extra flavor.
Substitute quinoa for rice for a higher-protein alternative.
Add a handful of spinach or chopped fresh dill to the vegetable layer for extra freshness.

Serve with warm pita bread or a simple side salad to round out the meal.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm them in the oven at 350°F (175°C) until heated through. For longer storage, freeze portions for up to 2 months and thaw overnight in the refrigerator before reheating.

How to Serve

The image shows a white round dish filled with a baked casserole that has a golden-brown, slightly crispy top layer with some slightly burnt edges. The base layer is creamy and light yellow, likely made of rice or a similar grain. On top, there is a layer of white creamy sauce scattered with chopped bright green parsley, small cubes of pale green cucumber, halves of shiny red cherry tomatoes, dark purple olives, and thin slices of purple onion. The ingredients are spread evenly across the top, creating a colorful and fresh look against the golden casserole beneath. The dish is placed on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use brown rice instead of white rice?

Yes, you can use brown rice, but it will require a longer baking time and more liquid. Adjust cooking time accordingly and consider pre-cooking the brown rice slightly before assembling the casserole.

Is it necessary to cover the casserole with foil during baking?

Covering the casserole with foil helps the rice cook evenly and keeps the moisture in. Removing the foil toward the end allows the feta cheese to brown and adds a nice texture.
