This fuss-free dump-and-bake chicken tzatziki casserole combines Greek flavors with the convenience of a one-dish meal. The rice cooks perfectly underneath tender chicken pieces while absorbing a creamy tzatziki-inspired sauce for a dinner that tastes like you spent hours in the kitchen.
I first created this recipe during a particularly chaotic week when I needed something that would practically cook itself. Now it appears on our dinner table at least twice a month when I need something comforting that doesn't require constant attention.
Ingredients
- Boneless chicken breasts or thighs: Provide protein and work perfectly in this gentle baking method
- Long grain white rice: Creates the perfect fluffy base that cooks evenly
- Greek yogurt: Forms the creamy tzatziki sauce while adding protein and tanginess
- Grated cucumber: Brings authentic tzatziki flavor and refreshing texture
- Fresh garlic: Adds essential aromatic flavor to both the rice and sauce
- Dried dill and oregano: Provide classic Greek herbal notes without requiring fresh herbs
- Ground cumin: Adds subtle warmth and depth that enhances the Mediterranean profile
- Lemon juice: Brightens all the flavors and cuts through the creaminess
- Feta cheese: Offers salty richness and authenticates the Greek inspiration
Step-by-Step Instructions
- Preheat Oven:
- Warm your oven to 375°F and lightly grease a 9x13 baking dish. This moderate temperature allows the rice to cook thoroughly without drying out the chicken.
- Create Flavor Base:
- Combine uncooked rice with broth, olive oil, garlic, and all dried herbs and spices directly in the baking dish. This creates a flavor foundation that will infuse into every grain of rice as it cooks.
- Prepare Tzatziki Layer:
- Arrange raw chicken pieces over the seasoned rice mixture. Then whisk together Greek yogurt, grated cucumber and lemon juice until smooth. Pour this mixture over everything, ensuring it covers the chicken and seeps into the rice below.
- Gentle Baking:
- Cover the dish tightly with foil to trap steam and moisture. This creates the perfect environment for cooking rice and chicken simultaneously without drying out either component. Bake for about 40 minutes until rice is tender and chicken reaches 165°F.
- Add Finishing Touches:
- Remove foil and sprinkle feta cheese over the top. Return to oven briefly to warm the cheese without fully melting it. The slight melt creates a beautiful texture contrast against the creamy sauce.
- Rest Before Serving:
- Allow the casserole to rest for 5 minutes after baking. This crucial step lets the sauce settle and the flavors meld together while making the dish easier to serve in neat portions.

The grated cucumber is truly the secret ingredient here. I discovered its importance when I once skipped it thinking the dish would be fine without it. The flavor dimension it adds cannot be replicated and the slight crunch it maintains even after baking provides wonderful textural contrast.
Storage Solutions
This casserole keeps beautifully in the refrigerator for up to 4 days. Store in airtight containers for best freshness. The flavors actually develop further overnight making leftovers sometimes even better than the original meal. For easy lunches portion into individual containers directly after cooking.
Simple Substitutions
If you prefer a heartier texture substitute brown rice but increase liquid by ½ cup and extend cooking time by 15 minutes. Quinoa works beautifully for a protein boost while remaining glutenfree. If fresh dill is available use 1 tablespoon chopped in place of dried for brighter flavor. Vegetarians can omit chicken and add 1 can drained chickpeas plus 1 cup diced zucchini for a satisfying meatfree version.
Serving Suggestions
This casserole pairs perfectly with a simple Greek salad of cucumbers, tomatoes, and red onion dressed with olive oil and red wine vinegar. Warm pita bread makes an excellent accompaniment for scooping up the creamy sauce. For a more substantial spread, add a side of kalamata olives and hummus. A chilled glass of Assyrtiko white wine or sparkling water with lemon completes the Mediterranean experience.
Making It Your Own
The basic formula here is wonderfully adaptable. Try adding spinach or chopped roasted red peppers to the yogurt mixture for color and extra nutrition. Artichoke hearts work beautifully when added before baking. For spice lovers a sprinkle of red pepper flakes or a few tablespoons of hot pepper rings adds pleasant heat that balances the creamy elements.
Recipe FAQs
- → Can I use brown rice instead of white rice?
Yes, you can substitute brown rice, but you'll need to increase the cooking time to approximately 50 minutes and may need to add about ¼ cup more liquid. Check for doneness before serving—the rice should be tender and all liquid absorbed.
- → Can I prepare this dish ahead of time?
Absolutely! Prepare everything up to the baking step, cover, and refrigerate for up to 12 hours. When ready to cook, remove from refrigerator about 30 minutes before baking and possibly add an extra 5-10 minutes to the cooking time since the dish will be cold.
- → What can I serve with this chicken tzatziki bake?
This one-pan meal pairs perfectly with a crisp Greek salad, warm pita bread, roasted vegetables, or a simple cucumber and tomato side dish. The refreshing flavors complement Mediterranean-style sides beautifully.
- → Can I use store-bought tzatziki instead of making it?
Yes, you can use about 1½ cups of store-bought tzatziki sauce to save time. You may want to thin it slightly with a little lemon juice or water before spreading over the chicken and rice for better coverage during baking.
- → Is there a way to make this dairy-free?
For a dairy-free version, substitute the Greek yogurt with dairy-free yogurt alternatives (like coconut or almond-based yogurt) and omit the feta cheese. You'll still get delicious Mediterranean flavors, though the texture may be slightly different.
- → What's the best way to store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in the microwave until warmed through or in a 350°F oven covered with foil for about 15-20 minutes. Add a splash of broth if the rice seems dry.
