Before You Begin
Before you start cooking, make sure you have all your ingredients prepped and ready to go. This will make the cooking process smoother and more enjoyable. Also, preheat your oven to 375°F (190°C) to ensure it’s ready when you are.
Ingredients You’ll Need
| Ingredient | Quantity |
|---|---|
| Cooked chicken, shredded or diced | 2 cups |
| Uncooked white rice | 1 cup |
| Chicken broth | 2 cups |
| Cucumber, diced | 1 cup |
| Red onion, finely chopped | 1/2 cup |
| Grape tomatoes, halved | 1 cup |
| Kalamata olives, pitted and sliced | 1/2 cup |
| Greek-style tzatziki sauce | 1 cup |
| Garlic powder | 1 teaspoon |
| Dried oregano | 1 teaspoon |
| Salt and pepper, to taste | |
| Feta cheese, crumbled | 1 cup |
| Fresh parsley, chopped for garnish | 2 tablespoons |
Step-by-Step Guide
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or similar casserole dish.
- In the prepared dish, add the uncooked rice and spread it evenly across the bottom.
- Pour the chicken broth over the rice, ensuring that the rice is submerged.
- Evenly distribute the cooked chicken over the rice.
- Scatter the diced cucumber, chopped red onion, halved grape tomatoes, and sliced Kalamata olives on top of the chicken layer.
- In a bowl, mix the tzatziki sauce with garlic powder, dried oregano, salt, and pepper.
- Spread the tzatziki sauce mixture evenly over the vegetables and chicken, ensuring everything is covered.
- Sprinkle the crumbled feta cheese across the top.
- 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.
- Remove the foil and bake for an additional 10 minutes, or until the feta cheese is slightly golden.
- Let the casserole cool for a few minutes, then garnish with chopped fresh parsley before serving.
Pointers for Perfection & How to Store
For an extra burst of flavor, marinate the chicken beforehand with lemon juice, olive oil, and oregano. Use brown rice as a healthier alternative but increase the cooking time accordingly. Substitute Greek yogurt for tzatziki sauce if desired, but add extra cucumber and dill to mimic its flavors. Pair the casserole with a side of warm pita bread for a complete meal. This dish can be prepped a night before and stored in the refrigerator, then baked fresh when needed.

Chicken Tzatziki Casserole
- Total Time: 45
- Yield: 6 servings 1x
- Diet: Gluten Free
Description
This Chicken Tzatziki Casserole is a fresh, Mediterranean-inspired twist on the classic weeknight bake. Juicy chunks of chicken and tender zucchini are baked in a rich, savory garlic-dill yogurt sauce, then topped with crumbled feta and crisp fresh cucumbers just before serving. It captures the cool, refreshing flavors of tzatziki in a warm, comforting, and naturally gluten-free dish.
Ingredients
— The Base —
1.5 lbs (700g) boneless, skinless chicken breasts, cut into 1-inch cubes
2 medium zucchini, halved lengthwise and sliced into half-moons
1 tablespoon olive oil
1 teaspoon dried oregano
½ teaspoon salt and ¼ teaspoon black pepper
— The Creamy Garlic-Dill Sauce —
1 cup plain Greek yogurt (full-fat is essential for baking)
¼ cup mayonnaise (helps stabilize the yogurt so it doesn’t split)
3 cloves garlic, minced
1 tablespoon fresh lemon juice
1 tablespoon cornstarch (thickener)
2 tablespoons fresh dill, chopped (plus extra for garnish)
— The Toppings —
½ cup crumbled feta cheese
1 cup English cucumber, diced (add AFTER baking)
Lemon wedges for serving
Instructions
1. Preheat Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish.
2. Prep Chicken & Veggies: In a large bowl, toss the cubed chicken and sliced zucchini with the olive oil, dried oregano, salt, and pepper. Spread this mixture evenly into the prepared casserole dish.
3. Make the Sauce: In a medium bowl, whisk together the full-fat Greek yogurt, mayonnaise, minced garlic, lemon juice, cornstarch, and chopped fresh dill until smooth and creamy.
4. Assemble: Pour the yogurt sauce evenly over the chicken and zucchini. Use a spatula to spread it out so everything is coated.
5. Bake: Bake for 25–30 minutes, or until the chicken is fully cooked (165°F) and the sauce is bubbly and slightly set.
6. Add Cheese: Remove from the oven and immediately sprinkle the crumbled feta cheese over the hot casserole.
7. Finish (The Tzatziki Twist): Let the casserole cool for about 5–10 minutes. Just before serving, scatter the cool, diced fresh cucumber and extra fresh dill on top. This temperature contrast creates the signature tzatziki experience.
8. Serve: Serve warm with a side of lemon wedges and gluten-free pita or rice.
Notes
Yogurt Tip: You must use full-fat Greek yogurt. Low-fat or non-fat yogurts have high water content and will separate/curdle when baked.
Why Mayonnaise?: Adding a small amount of mayonnaise helps stabilize the yogurt sauce, ensuring it stays creamy under heat rather than grainy.
Cucumber: Do not bake the cucumber! Adding it fresh at the end provides the necessary crunch and freshness that makes this dish taste like tzatziki.
Carbs: This dish is low-carb on its own. Serve over cauliflower rice for keto, or with roasted potatoes for a heartier meal.
