How to Make Mediterranean Chicken Casserole

Preheat the oven to 180 degrees C (355 F). This sets the perfect cooking environment for our delightful casserole.
Prepare the chicken thighs by trimming excess fat. Cut them into roughly 3 cm (1-inch cubes), then pat them dry and season with sea salt and freshly ground black pepper to enhance the flavor.
Heat the olive oil in a large, heavy-based Dutch oven or saucepan over high heat until shimmering. Add half the chicken and brown for several minutes on all sides, then transfer to a plate. Repeat with the remaining chicken.
Sauté the onion over low heat for about 2 minutes until soft, then stir in the garlic and cook for another minute, ensuring it doesn’t burn for that lovely aromatic base.
Combine the cooked chicken with any juices in the pan. Add the crushed tomatoes, chicken stock, oregano, basil, and chilli flakes (if you’re using them). Stir well to de-glaze the pan, and bring to a simmer.
Mix in the zucchini and capsicum, stir well to combine, cover, and place in the preheated oven. Cook for 30-40 minutes until the chicken is tender and vegetables are cooked through.
Garnish the dish by removing it from the oven. Add the olives and chopped parsley, checking the seasoning, and adjust with salt, pepper, or extra chilli flakes if needed.
Serve the casserole warm, either in a dish or directly from the pan. Don’t forget to sprinkle some extra chopped parsley and crumbled feta on top just before serving for that delightful finishing touch!

Optional: Garnish with a drizzle of olive oil for added richness.

Mediterranean Chicken Casserole Recipe FAQs

How do I select the best chicken thighs for my casserole?
Absolutely! When choosing chicken thighs, look for ones that are skinless and boneless, preferably with a bright pink color and no dark spots. The fresher they are, the more tender and flavorful your casserole will be!

What’s the best way to store leftovers of the Mediterranean Chicken Casserole?
For sure! Store any leftover casserole in an airtight container in the fridge for up to 3 days. Make sure it has cooled to room temperature before sealing, as this helps keep it fresh and safe to eat.

Can I freeze Mediterranean Chicken Casserole, and how?
Yes, you can! To freeze, let the casserole cool completely. Then, portion it into individual servings or place it in one large airtight container. Label with the date and freeze for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge before reheating.

What if my casserole is too watery after baking?
Very! If you find your casserole a bit too watery, it may be due to excess moisture from the vegetables. Next time, try letting the zucchini and capsicum drain on a paper towel before adding them. Alternatively, you can simmer the casserole uncovered for the last 10 minutes, helping it to thicken up before serving.

Are there any dietary considerations I should be aware of?
Of course! This casserole contains chicken and feta, so it’s not suitable for those with a dairy allergy or lactose intolerance. For a dairy-free option, you can omit the feta or use a dairy-free alternative. Always check labels on canned products for potential allergens, especially if serving to guests.

How can I make this Mediterranean Chicken Casserole more flavorful?
Great question! For an extra flavor boost, consider marinating the chicken in olive oil, garlic, and herbs for a few hours before cooking. You can also add some lemon zest or a splash of balsamic vinegar to enhance the flavors. The more, the merrier!
