Ingredients
- Cooked Chicken (2 cups): Shredded or diced chicken adds lean protein and a hearty base for the casserole.
- Cherry Tomatoes (1 cup): Halved for bursts of natural sweetness and juiciness in every bite.
- Black Olives (1/2 cup): Sliced olives contribute a salty, briny depth characteristic of Greek cuisine.
- Feta Cheese (1/2 cup): Crumbled tangy and creamy feta enhances the Mediterranean flavor profile.
- Heavy Cream (1 cup): Adds richness and a luscious, creamy texture to bind the casserole.
- Dried Oregano (1 teaspoon): Earthy herb that infuses classic Greek seasoning throughout the dish.
- Garlic Powder (1 teaspoon): Provides warm, savory undertones without overpowering.
- Salt and Pepper: To taste, for seasoning and balancing flavors.
- Olive Oil: Used for greasing the baking dish to prevent sticking and add subtle flavor.
Instructions
- Preheat the Oven to 375°F (190°C)
-
Set your oven to the correct temperature to ensure even cooking and that the casserole heats through perfectly. Preheating is essential for avoiding uneven textures.
- Combine All Ingredients Thoroughly
-
In a large mixing bowl, add the shredded chicken, halved cherry tomatoes, sliced black olives, crumbled feta cheese, heavy cream, dried oregano, garlic powder, salt, and pepper. Stir carefully until evenly combined, allowing flavors to meld before baking.
- Prepare the Baking Dish
-
Grease a 9×9-inch baking dish generously with olive oil to prevent sticking and add a subtle richness to the base. This step makes cleanup easier and helps with browning.
- Transfer the Mixture to the Dish
-
Pour the well-mixed casserole ingredients into the prepared baking dish. Spread it out evenly to promote consistent cooking and ensure every serving has a perfect mix.
- Bake the Casserole
-
Bake uncovered for 25 to 30 minutes, or until the casserole is heated through and bubbly on top. This baking step allows the cream to thicken and flavors to develop fully.
- Let the Dish Rest
-
Allow the casserole to cool slightly for about 5 minutes before serving. This resting period helps the layers set so slices hold together and flavors deepen.
- Use cooked chicken from rotisserie or leftovers to save prep time.
- Substitute heavy cream with full-fat coconut milk for a dairy-free version.
- Adjust the level of salt carefully because feta and olives are naturally salty.
Storage Tips
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven to maintain creaminess and prevent drying out.
Serving Suggestions
This casserole pairs well with a fresh green salad or roasted vegetables for a complete low-carb meal. Garnish with extra oregano or lemon zest for added brightness and aroma.
- Use fresh herbs alongside dried oregano for enhanced flavor complexity.
- For added texture, sprinkle some toasted pine nuts on top before serving.
- Ensure heavy cream is at room temperature to blend more smoothly into the mixture.
