I’m always on the lookout for hearty, comforting dinners that come together with minimal fuss, and this Quick Mediterranean Chicken Casserole has quickly become one of my weeknight staples. It’s packed with flavor, combining juicy chicken, vibrant vegetables, creamy orzo, and a touch of Mediterranean flair from herbs, garlic, and olive oil. The best part? It’s all made in one dish—easy prep and even easier cleanup.

There’s something so satisfying about a casserole that feels both nourishing and indulgent. With just a handful of simple ingredients, this dish brings warmth and richness to the table in under an hour. It’s the kind of meal that makes you feel like you’ve cooked something truly special without needing to spend hours in the kitchen.

Why You’ll Love This Quick Mediterranean Chicken Casserole

This casserole is a true time-saver, perfect for busy evenings or when you’re feeding a hungry crowd. The chicken stays tender and juicy thanks to a quick pan-sear and finishing in the oven, while the orzo soaks up all the savory juices. The Mediterranean flavors—think roasted peppers, onions, oregano, and garlic—create a depth that feels both refreshing and comforting. Plus, it’s easy to adapt to what you have on hand.

What Kind of Chicken Should I Use?

For this recipe, I prefer using boneless, skinless chicken thighs. They hold up beautifully in the oven, stay juicy, and develop a delicious golden crust when seared. However, boneless chicken breasts will work just fine if that’s what you have—they may just require a bit less time in the oven to avoid drying out. If you’re using bone-in cuts, add a bit more baking time to ensure they cook through.

Options for Substitutions

This casserole is wonderfully flexible. Not a fan of orzo? Try rice, couscous, or even quinoa. You can swap the chicken for turkey or even chickpeas for a vegetarian twist. Don’t have bell peppers or red onion? Zucchini, spinach, cherry tomatoes, or olives make great additions. And if you’re dairy-free, skip the cheese or opt for a plant-based alternative. The beauty of this dish lies in its adaptability to whatever’s in your fridge.

Ingredients for This Quick Mediterranean Chicken Casserole

• Chicken thighs (boneless, skinless): These are the star of the dish—juicy, flavorful, and cook evenly without drying out.
• Orzo pasta: A rice-shaped pasta that absorbs all the savory juices from the chicken and vegetables, giving a creamy, risotto-like texture.
• Red and green bell peppers: These add a sweet, slightly smoky flavor and vibrant color.
• Red onion: Offers a touch of sweetness and depth that balances the savory elements.
• Garlic cloves: Essential for Mediterranean flavor—adds aroma and a warm, earthy bite.
• Olive oil: Used for sautéing and bringing a rich, fruity base to the dish.
• Chicken broth: Provides moisture for the orzo and depth of flavor.
• Mozzarella or feta cheese: Melts into the dish, adding creamy, tangy richness.
• Fresh parsley: For a fresh finish and a burst of color.
• Oregano (dried or fresh): A key Mediterranean herb that brings a peppery, herbal lift.
• Salt and black pepper: Essential seasoning to balance and enhance the ingredients.

Step 1: Sear the Chicken

Start by patting your chicken thighs dry and seasoning both sides generously with salt, pepper, and oregano. Heat a bit of olive oil in a large oven-safe skillet or casserole dish over medium-high heat. Sear the chicken thighs for about 3–4 minutes per side, until golden brown. Remove them from the pan and set aside.

Step 2: Sauté the Vegetables

In the same skillet, add a touch more olive oil if needed. Toss in the diced bell peppers, red onion, and minced garlic. Cook for 5–6 minutes, stirring occasionally, until the vegetables are softened and fragrant.

Step 3: Add Orzo and Broth

Stir in the orzo pasta and toast it lightly for 1–2 minutes, which helps build flavor and keeps it from getting mushy. Then pour in the chicken broth, scraping up any browned bits from the bottom of the pan to enrich the base.

Step 4: Nestle Chicken and Bake

Place the seared chicken thighs back into the skillet, nestling them into the orzo and vegetables. Sprinkle with shredded mozzarella or crumbled feta, then transfer the skillet to a preheated oven at 375°F (190°C). Bake uncovered for 20–25 minutes, or until the chicken is fully cooked and the orzo has absorbed most of the liquid.

Step 5: Garnish and Serve

Once out of the oven, let the dish rest for 5 minutes. Sprinkle with freshly chopped parsley for a bright, herbaceous finish. Serve warm, straight from the pan, with lemon wedges on the side if desired.

How Long to Prepare the Quick Mediterranean Chicken Casserole

Prep Time: Most of the prep is simple—chopping vegetables, seasoning the chicken, and preheating the oven. This takes about 15 minutes. Since it’s a one-pan dish, you won’t have a pile of dishes afterward either.

Cook Time: Once prepped, the searing and sautéing take another 10–15 minutes on the stovetop, followed by a 20–25 minute bake in the oven. In total, you’re looking at 45–50 minutes from start to finish for a satisfying homemade meal.

Tips for Perfect Quick Mediterranean Chicken Casserole

• Sear the chicken well: Don’t skip the searing step—it locks in juices and adds a beautiful golden crust that deepens the flavor.
• Use hot broth: Adding warm or hot chicken broth helps maintain the cooking temperature and reduces oven time.
• Toast the orzo: This step adds a nutty depth and keeps the pasta from becoming overly soft.
• Don’t overbake: Keep an eye on the oven around the 20-minute mark. Overcooking can dry out both the chicken and orzo.
• Finish with fresh herbs: Parsley or even fresh basil can brighten the dish and balance the rich flavors.

Watch Out for These Mistakes While Cooking

• Using cold chicken straight from the fridge: Let it sit out for 10 minutes before searing to ensure even cooking.
• Skipping the deglazing: Be sure to scrape up the browned bits in the pan after sautéing—they add essential flavor.
• Adding too much broth: Orzo should absorb the liquid but not swim in it. Stick to the recommended amount.
• Covering during baking: This traps steam and can make the orzo soggy. Bake uncovered for the best texture.
• Neglecting to rest: Resting the dish for 5 minutes helps the orzo set and flavors meld.

Storage Instructions

Refrigeration: Let the casserole cool completely, then transfer leftovers to an airtight container. It keeps well in the fridge for up to 4 days. The orzo may continue to absorb moisture, so add a splash of broth or water when reheating to loosen it up.

Freezing: For longer storage, portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating: Reheat in the oven at 350°F (175°C) covered with foil for 15–20 minutes, or microwave individual portions with a bit of added liquid for 2–3 minutes.
