So, let’s dive into the world of Greek-inspired comfort food and discover why Chicken Tzatziki Casserole deserves a spot in your recipe collection.
What is Chicken Tzatziki Casserole?
Chicken Tzatziki Casserole is a baked one-pan dish that layers chicken breast, long-grain rice, zucchini, and tomatoes with a fragrant seasoning blend. The dish is baked until the rice absorbs all the savory chicken broth and the chicken turns tender. It’s then topped with fresh tzatziki sauce, tangy pickled onions, and creamy feta cheese—a combination that creates both depth and brightness in every bite.
The roots of this recipe lie in the marriage between classic casserole-style cooking and the flavor profile of Greek cuisine. Tzatziki, a traditional Greek yogurt-based sauce with cucumber, garlic, and dill, is usually served as a dip or accompaniment to grilled meats. Incorporating it into a baked casserole offers a creative twist that elevates the dish while keeping it balanced and refreshing.
Unlike heavier casseroles that rely on cream, butter, or condensed soup, this Mediterranean version is naturally lighter. The rice provides comfort, while the vegetables add nutrition and freshness. The addition of lemon and pickled onions cuts through richness, ensuring the dish never feels too heavy.
In many ways, this casserole represents the best of both worlds:
- The heartiness and convenience of a casserole.
- The lightness and vibrancy of Greek flavors.
That’s why Chicken Tzatziki Casserole is not just dinner—it’s an experience of Mediterranean comfort food at its finest.

Essential Ingredients and Their Role
The magic of this dish lies in how simple ingredients come together to create a symphony of flavors. Let’s break down the key players:
🥩 Chicken
- The foundation of the dish. Chicken breast or thighs both work, though breasts are leaner and cook quickly.
- Provides high-quality protein and absorbs Mediterranean spices beautifully.
Substitute: Tofu, chickpeas, or lentils for a vegetarian version.
🍚 Rice
- Long-grain rice like basmati is ideal—it stays fluffy and absorbs flavors without becoming sticky.
- Provides a comforting starch base for the casserole.
Substitute: Cauliflower rice for a low-carb option.
🥒 Zucchini
- Adds moisture, nutrients, and a mild sweetness that balances the dish.
- Zucchini is rich in antioxidants and fiber, making it both nutritious and filling.
🍅 Grape Tomatoes
- Their natural sweetness bursts during baking, enhancing flavor.
- Adds juiciness and freshness, preventing the dish from feeling heavy.
🧅 Onions
- Yellow onion for depth, and red onion (pickled) for tanginess and crunch.
🍋 Lemon
- Lemon wedges baked with the casserole infuse brightness and acidity.
- Fresh juice squeezed over before serving enhances freshness.
🧂 Seasonings
- Greek seasoning: A blend of oregano, garlic powder, onion powder, thyme, and basil.
- Paprika mix: Smoked paprika, cayenne, turmeric, and seasoning salt for warmth and color.
🧀 Feta Cheese
- A salty, tangy contrast to the richness of chicken and rice.
- Use sparingly as a topping or generously for extra creaminess.
Substitute: Dairy-free feta alternatives.
🥛 Tzatziki Sauce
- The star topping that transforms the dish. Cool, garlicky, and refreshing, it ties all flavors together.
- Can be homemade or store-bought.
Substitute: Dairy-free tzatziki made with coconut yogurt or cashew yogurt.
Step-by-Step Recipe Instructions
Cooking this casserole may seem elaborate, but it’s incredibly straightforward once broken into steps:
Step 1: Prepare the Seasoning Mix

- This mix ensures the chicken and rice bake with layers of smoky warmth.
Step 2: Pickle the Red Onions
- In a small bowl, mix red wine vinegar, sugar, and salt.
- Add thinly sliced red onions and let them soak.
- These will act as a tangy topping later.
Step 3: Assemble the Casserole
- Preheat oven to 375°F (190°C).
- In a 9×13-inch casserole dish, add diced chicken and coat with half the seasoning mix.
- Layer uncooked rice evenly.
- Top with zucchini and grape tomatoes.
- In another bowl, whisk chicken stock with remaining seasoning and Greek herbs.
- Pour over the casserole and finish with lemon wedges and feta crumbles.
Step 4: Bake
- Cover tightly with foil and bake for 40 minutes.
- Remove foil and bake another 10–20 minutes, until rice is fluffy and liquid is absorbed.
Step 5: Garnish and Serve
- Fluff the rice gently.
- Remove lemon wedges if desired.
- Top with feta, pickled onions, fresh parsley, and a generous dollop of tzatziki.
- Serve warm with pita bread.
Common Mistakes and How to Avoid Them
