Ingredients

• Cooked chicken shredded or diced: adds protein and saves cook time, leftover rotisserie chicken works great
• Uncooked white rice: the comfort base that absorbs all the flavors
• Chicken broth: infuses the rice with savory goodness, pick low sodium for control
• Cucumber diced: brings crunch and coolness against the warm layers
• Red onion finely chopped: adds a gentle sharpness balancing the creaminess
• Grape tomatoes halved: bursts of sweetness
• Kalamata olives sliced and pitted: introduce a briny depth, pick firm and plump ones for best taste
• Greek-style tzatziki sauce: the star creamy sauce packed with garlic and herbs
• Garlic powder: enhances the garlic flavor gently
• Dried oregano: earthy Mediterranean aroma
• Salt and pepper: essential seasoning
• Feta cheese crumbled: lends a salty tang and melts slightly as it bakes
• Fresh parsley chopped for garnish: adds a pop of color and freshness

Step-by-Step Instructions

Preheat the oven:

Set your oven to 375 degrees Fahrenheit or 190 degrees Celsius. Grease a 9x13-inch or similar sized baking dish to prevent sticking and make serving easier.

Layer the rice:

Pour the uncooked rice into the baking dish and spread it evenly to create the base layer. This will absorb all the delicious liquids and spices as it cooks.

Add the broth:

Pour the chicken broth over the rice carefully, making sure it covers the rice completely. This will cook the rice evenly and infuse it with flavor.

Place the chicken:

Evenly spread the prepared cooked chicken over the rice and broth mixture. This ensures each bite will have tender protein throughout.

Add the vegetables:

Scatter diced cucumber, chopped red onion, halved grape tomatoes, and sliced Kalamata olives evenly on top of the chicken. This adds fresh texture and balanced savory notes.

Mix the sauce:

In a separate bowl, stir the tzatziki sauce with garlic powder, dried oregano, salt, and pepper until well combined. This herby sauce layers in creamy flavor.

Spread the sauce:

Evenly smear the tzatziki mixture on top of the vegetables and chicken, making sure everything is well covered for maximum flavor and moisture.

Top with feta:

Sprinkle crumbled feta cheese across the entire dish, allowing it to melt slightly and add a salty tang to each bite.

Bake covered:

Cover the casserole with foil to lock in moisture. Bake in the preheated oven for 45 minutes until the rice is tender and chicken is warmed through.

Finish baking uncovered:

Remove the foil and continue baking for another 10 minutes so the feta cheese gets lightly golden and adds a bit of texture.

Rest and garnish:

Let the casserole cool for about 5 minutes outside the oven. Sprinkle with fresh chopped parsley for an herbaceous finish before serving.

Pin it

I love how the Kalamata olives bring a subtle salty bite that contrasts perfectly with the cool, creamy tzatziki. My family always perks up when they see that tangy sauce layered on top – it makes this dish feel special yet approachable.

Storage tips

Store leftovers in an airtight container in the refrigerator for up to four days. Reheat gently in the oven or microwave to retain moisture. For longer storage, freeze in portions and thaw overnight in the fridge before reheating.

Ingredient substitutions

Swap white rice for brown rice or quinoa for a whole grain twist though cooking times may vary. Chicken broth can be replaced with vegetable broth if you prefer a lighter flavor or have dietary restrictions. If you don’t have tzatziki, plain Greek yogurt mixed with cucumber and garlic can work in a pinch.

Serving suggestions

Serve this casserole alongside a simple green salad or warm flatbread to round out the Mediterranean vibe. A squeeze of fresh lemon over the top brightens the dish beautifully. Leftover tzatziki makes a great dipping sauce or topping.

Frequently Asked Questions

→ Can I use brown rice instead of white rice?

Yes, but adjust the baking time and broth amount since brown rice takes longer to cook and absorbs more liquid.

→ How can I make this dish spicier?

Adding a pinch of crushed red pepper flakes to the tzatziki mix or sprinkling some cayenne over the top before baking will give it a gentle heat.

→ What can I substitute for Kalamata olives?

Green olives or even capers offer a similar salty and briny flavor if Kalamata olives are unavailable.

→ Can I prepare this casserole in advance?

Yes, assemble everything ahead of time, cover tightly, and refrigerate. Bake when ready, adding a few extra minutes if chilled.

→ Is it necessary to cover the dish with foil while baking?

Covering helps steam the rice and keep the chicken moist. Removing the foil near the end lets the feta brown nicely.
