How To Make the Quick Mediterranean Chicken Casserole

Step 1: Sear the Chicken

Heat olive oil in a large oven-safe skillet over medium-high heat. Season chicken thighs with salt, pepper, paprika, and oregano. Sear skin-side down for 5–6 minutes until golden brown. Flip and cook another 2 minutes. Remove and set aside.

Step 2: Sauté the Vegetables

In the same skillet, add sliced onions and red peppers. Sauté for 4–5 minutes until softened. Add minced garlic and cook for another minute until fragrant.

Step 3: Build the Flavor Base

Stir in olives and lemon zest. Arrange the seared chicken back into the skillet, nestling it among the vegetables. Squeeze lemon juice over everything and sprinkle with crumbled feta.

Step 4: Bake to Perfection

Transfer the skillet to a preheated oven at 375°F (190°C). Bake for 25–30 minutes until the chicken is fully cooked and juices run clear.

Step 5: Garnish and Serve

Remove from the oven and let rest for 5 minutes. Sprinkle with fresh chopped parsley before serving for a burst of color and freshness.

Serving & Storing This Casserole

This dish is incredibly versatile when it comes to serving. Spoon generous portions over fluffy couscous, rice pilaf, or even crusty bread to soak up the flavorful juices. It also pairs well with a crisp green salad or a side of roasted vegetables.

Leftovers? Even better the next day. Store in an airtight container in the fridge for up to 4 days. To reheat, place in a covered dish in the oven at 350°F or microwave individual portions for 2–3 minutes until warmed through.

Frequently Asked Questions

How do I make this dish spicier?

Add a pinch of crushed red pepper flakes while sautéing the garlic, or stir in a spoonful of harissa paste for a bolder kick.

Can I use chicken breasts instead of thighs?

Yes, but thighs remain juicier and more flavorful. If using breasts, be careful not to overbake as they dry out more easily.

Is this casserole freezer-friendly?

Definitely! Allow the casserole to cool completely, then store in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
