It’s a one-pan wonder filled with vibrant Mediterranean ingredients like juicy chicken, olives, cherry tomatoes, garlic, and a warm blend of herbs.

Why You’ll Love This Quick Mediterranean Chicken Casserole

This casserole isn’t just quick, it’s crave-worthy. It brings together lean protein, fresh vegetables, and pantry staples in a way that feels both rustic and nourishing. The layered Mediterranean flavors develop beautifully in the oven, creating a dish that tastes like it’s been simmering all day, even though it takes under an hour from start to finish.

There’s no need to make a separate side dish either—it’s a complete meal in one. And since it’s baked, the hands-on time is minimal, giving you more moments to relax or prep for the next day.

What Kind of Chicken Should I Use?

Boneless, skinless chicken thighs or breasts both work wonderfully in this recipe. Thighs will give a bit more richness and tenderness, while breasts are leaner and soak up the herby, garlicky sauce beautifully. If you’re in a hurry, pre-cooked shredded rotisserie chicken can also be folded in toward the end and baked just long enough to heat through and mingle with the sauce.

Ingredients for the Quick Mediterranean Chicken Casserole

For this recipe, you’ll rely on a mix of fresh and pantry ingredients that bring depth and brightness. The key is using flavorful components that don’t require much fuss. Here’s what you’ll need:

• Chicken thighs or breasts
  These are the protein backbone of the dish. They absorb all the savory Mediterranean flavors.

  These salty, briny olives add that signature Mediterranean flair and balance the sweetness of the tomatoes.
• Red onion
  Provides a mellow bite and gorgeous color as it softens during baking.
• Garlic cloves
  Essential for aromatic depth—garlic brings everything together.
• Dried oregano and thyme
  These earthy herbs pair perfectly with the rest of the ingredients and amplify the savory flavors.
• Olive oil
  Helps everything roast evenly and adds richness.
• Feta cheese (optional)
  Adds creamy, tangy contrast if you choose to sprinkle some on before serving.
• Salt and pepper
  Simple seasonings that enhance and tie everything together.

How To Make the Quick Mediterranean Chicken Casserole

Step 1: Prep the Chicken

Preheat your oven to 400°F (200°C). Season your chicken thighs or breasts with salt, pepper, oregano, and thyme on both sides. Set them aside while you prep the rest.

Step 2: Assemble the Casserole

In a large baking dish, toss the cherry tomatoes, sliced red onion, garlic cloves, and Kalamata olives with a drizzle of olive oil. Nestle the chicken into the mixture, spooning some of the veggies around and on top of each piece.

Step 3: Bake to Perfection

Bake uncovered for about 30–35 minutes, or until the chicken is fully cooked and the tomatoes have burst into a juicy, aromatic sauce. You’ll notice the edges caramelizing just slightly—that’s flavor gold.

Step 4: Garnish and Serve

Once out of the oven, sprinkle with crumbled feta if using, and a few extra olives or fresh herbs like parsley or basil for added freshness.

How to Serve and Store Your Mediterranean Chicken Casserole

This recipe feeds about 4 people generously, though it’s easy to double if you’re feeding a crowd. It’s best served hot, right out of the oven, with a spoon to catch all that juicy tomato and olive goodness.

If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or on the stovetop, adding a splash of broth or water if needed to rehydrate the sauce.
