Step‑by‑Step Instructions for Greek Chicken Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to ensure it’s warm and ready for your Greek Chicken Casserole. This temperature will help the dish cook evenly, allowing the flavors to blend perfectly during baking.

Step 2: Brown the Chicken
In a large, oven-safe skillet, heat 1 tablespoon of olive oil over medium-high heat. Season your chicken breasts with salt and pepper, then add them to the skillet. Brown the chicken for about 5-6 minutes on each side, until golden and cooked through. Once done, remove the chicken from the skillet and set it aside.

Step 3: Sauté the Onions
Add the remaining tablespoon of olive oil to the skillet and reduce the heat to medium. Sauté the diced onion for 2-3 minutes until it becomes translucent and fragrant. This step lays the foundation for the rich flavors that will blossom in your Greek Chicken Casserole.

Step 4: Add Garlic and Vegetables
Stir in the minced garlic, diced red bell pepper, and zucchini. Continue cooking for 3-4 minutes, stirring occasionally, until the vegetables soften and color beautifully. This mixture will provide both texture and a burst of color to your casserole.

Step 5: Incorporate Spinach and Herbs
Next, add the fresh spinach, dried oregano, dried thyme, and crushed red pepper flakes (if using). Cook for another 1-2 minutes, until the spinach wilts down significantly. The herbs will infuse the vegetables with Mediterranean essence, making your dish all the more delightful.

Step 6: Mix in Orzo and Liquid Ingredients
Fold in the uncooked orzo, chicken broth, and freshly squeezed lemon juice. Stir the mixture well to ensure everything is combined and the orzo is evenly distributed. This creates a creamy base that will absorb all the flavors during baking.

Step 7: Return Chicken to the Skillet
Carefully place the browned chicken back into the skillet, laying it evenly over the orzo mixture. Make sure the chicken is nestled comfortably in the blend of vegetables and orzo, allowing the juices to flow into the casserole as it cooks.

Step 8: Bake the Casserole
Cover the skillet with a lid or aluminum foil and transfer it to the preheated oven. Bake for 25-30 minutes, or until the orzo is tender and has absorbed most of the liquid. You’ll know it’s done when the orzo has plumped up significantly and the dish looks invitingly creamy.

Step 9: Add Toppings and Finish Baking
Remove the cover and generously sprinkle the top of the casserole with crumbled feta cheese, fresh parsley, and any Kalamata olives you desire. Return the skillet to the oven and bake for an additional 5 minutes, just until the feta softens and begins to melt slightly, adding lusciousness to the dish.

Step 10: Serve and Enjoy
Once the Greek Chicken Casserole is ready, take it out of the oven and let it rest for a few minutes. This allows the flavors to meld together beautifully. Serve warm, and savor the robust Mediterranean flavors with each hearty bite!
