Ingredients

For the Casserole Base:

• 2 cups cooked chicken, shredded or diced – Provides protein and heartiness.

Vegetables & Mediterranean Flavors:

• 1 cup cucumber, diced – Adds crunch and freshness.
• ½ cup red onion, finely chopped – Provides a subtle bite.
• 1 cup grape tomatoes, halved – Sweetness and juiciness balance the dish.
• ½ cup Kalamata olives, pitted and sliced – Salty, briny flavor.

Tzatziki & Seasoning:

• 1 cup Greek-style tzatziki sauce – Creamy, garlicky base for the casserole.
• 1 tsp garlic powder – Enhances flavor.
• 1 tsp dried oregano – Classic Mediterranean herb.
• Salt and pepper, to taste – Balances flavors.

Toppings & Garnish:

• 1 cup feta cheese, crumbled – Adds tang and creaminess.
• 2 tbsp fresh parsley, chopped – For color and fresh flavor.

Tip: Use pre-cooked rotisserie chicken to save time, and opt for Greek-style tzatziki with authentic ingredients for best flavor.

Preparation Method

Step 1: Preheat and Prepare the Dish

1. Preheat your oven to 375°F (190°C).
2. Grease a 9×13-inch baking dish lightly with olive oil or non-stick spray.

Step 2: Layer the Base

1. Spread uncooked rice evenly at the bottom of the prepared dish.
2. Pour chicken broth over the rice, ensuring it is fully submerged.

Tip: Even coverage ensures the rice cooks evenly and absorbs all the flavors.

Step 3: Add Chicken and Vegetables

1. Evenly distribute the cooked chicken over the rice.
2. Layer the cucumber, red onion, grape tomatoes, and Kalamata olives on top of the chicken.

Tip: Chop vegetables uniformly for even cooking and presentation.

Step 4: Prepare and Add Tzatziki Mixture

1. In a bowl, mix tzatziki sauce with garlic powder, oregano, salt, and pepper.
2. Spread this mixture evenly over the layered casserole.

Tip: Mixing the tzatziki with seasoning enhances its flavor and ensures it penetrates the casserole evenly.

Step 5: Add Feta and Bake

1. Sprinkle crumbled feta cheese over the top of the casserole.
2. Cover the dish with foil and bake for 45 minutes, until rice is tender and cooked through.
3. Remove foil and bake an additional 10 minutes until feta is lightly golden.

Tip: The final uncovered bake step creates a beautiful golden top and slightly crisp edges.

Step 6: Rest and Serve

1. Let the casserole rest for 5 minutes before serving.
2. Garnish with fresh parsley for color and fresh flavor.
3. Serve warm, paired with a side salad, pita bread, or roasted vegetables.

Tips and Tricks for a Perfect Tzatziki Casserole

1. Use Greek-style tzatziki: Authentic tzatziki has yogurt, cucumber, and garlic, giving the casserole a fresh, tangy flavor.
2. Avoid watery vegetables: Pat cucumbers or thawed spinach dry to prevent a soggy casserole.
3. Layering matters: Layer ingredients evenly to ensure balanced flavors in every bite.
4. Adjust seasoning at the end: Taste before serving and add extra salt, pepper, or herbs as needed.
5. Make ahead: Assemble the casserole in advance, cover tightly, and refrigerate for up to 24 hours before baking.

Variations

• Protein Options: Use cooked turkey, shredded rotisserie chicken, or lamb for a Mediterranean twist.
• Grain Substitutes: Substitute white rice with brown rice, quinoa, or cauliflower rice for a healthier option.
• Vegetable Boost: Add roasted bell peppers, zucchini, or eggplant for extra flavor and nutrients.
• Cheese Upgrade: Combine feta with shredded mozzarella or goat cheese for extra creaminess.
