This Mediterranean Greek Chicken Casserole transforms simple ingredients into a restaurant-worthy dish with minimal effort. The combination of tender orzo pasta, succulent shredded chicken, and classic Greek flavors creates a comforting meal that feels both familiar and exciting.
I first created this casserole when hosting my Greek friend for dinner. She closed her eyes with the first bite and said it reminded her of summers in Santorini. Now it's my go-to dish whenever I want to impress guests without spending hours in the kitchen.

How To Make Greek Chicken Casserole
- Prep the base
- Start by preheating your oven to 400°F and placing your diced red onion in a 9x13 baking dish. Drizzle with olive oil and roast for just 5 minutes. This brief roasting softens the onion and releases its natural sweetness without requiring a separate pan for sautéing.
- Combine ingredients
- Remove the dish from the oven and add uncooked orzo pasta minced garlic sundried tomatoes chopped spinach olives if using dried oregano olive oil and salt. Stir until everything is evenly distributed. The heat from the dish will begin to wake up the garlic and oregano releasing their aromatic oils.
- Add proteins and brightness
- Fold in your shredded chicken crumbled feta cheese fresh lemon juice and zest. The lemon instantly brightens the mixture while the feta begins to slightly soften around the edges creating pockets of creamy saltiness throughout the casserole.
- Add liquid and bake
- Pour chicken broth over the mixture ensuring the orzo is mostly submerged. Cover tightly with foil and bake for 15 minutes. This initial covered baking allows the orzo to begin absorbing the flavorful liquid without drying out the top.
- Finish uncovered
- Remove the foil stir everything well and return to the oven uncovered for another 15-20 minutes. This final uncovered bake allows excess moisture to evaporate leaving you with perfectly tender orzo while creating delicious crispy edges around the perimeter of the dish.
- Rest and serve
- Allow the casserole to rest for 5 minutes before serving. This critical resting period allows the remaining liquid to be fully absorbed and flavors to settle. Garnish with additional feta and fresh parsley for a professional finishing touch.
My absolute favorite part of this dish is how the sundried tomatoes plump up during baking absorbing some of the broth while simultaneously releasing their intense flavor throughout the casserole. My mother who claims to dislike sundried tomatoes always picks them out first in this dish.
Make It Your Own
This Greek chicken casserole welcomes adaptations based on what you have available. For a vegetarian version replace the chicken with 2 cans of drained chickpeas and use vegetable broth instead of chicken broth. The protein content remains high while the Mediterranean flavors shine even brighter against the nutty backdrop of chickpeas.
If you're watching carbs consider swapping half the orzo for riced cauliflower. Add the cauliflower during the last 10 minutes of baking to prevent it from becoming too soft. This modification reduces the carbohydrate content while maintaining the satisfying texture and volume of the original recipe.
Storage and Reheating
The flavors in this casserole actually improve overnight as the ingredients have time to meld together. Store leftovers in an airtight container in the refrigerator for up to 5 days. For best reheating results add a splash of water or broth to prevent dryness then cover and microwave until just heated through about 2 minutes for a single serving.
For freezing portion the cooled casserole into individual servings in freezer safe containers. This allows for quick single serving meals without defrosting the entire batch. Thaw overnight in the refrigerator before reheating for best texture results.

Serving Suggestions
This versatile casserole can stand alone as a complete meal but pairs beautifully with simple sides for a more elaborate dinner. A crisp Greek salad with cucumbers tomatoes and a simple vinaigrette offers textural contrast to the soft hearty casserole. Warm pita bread brushed with olive oil and sprinkled with oregano provides the perfect vehicle for scooping up every last morsel from your plate.
For a truly authentic Greek experience serve with a side of tzatziki sauce. The cool cucumber yogurt combination cuts through the richness of the casserole while complementing the Mediterranean flavor profile. Just a small dollop alongside each portion elevates the entire dining experience.
