Instructions

Preheat Oven and Prepare Casserole Dish

Set your oven to 190°C (375°F) and grease a 23×33 cm casserole dish with olive oil or butter. Preheating ensures even cooking, while greasing prevents sticking and easy serving.

Sauté Onion and Bell Pepper

Heat a drizzle of olive oil in a large skillet over medium heat. Add the finely chopped onion and diced red bell pepper, cooking for about 4 to 5 minutes until they soften and become fragrant. This step mellows the vegetables and deepens their flavor.

Add Garlic and Cook Briefly

Stir in the minced garlic, cooking for an additional minute until it becomes aromatic. Avoid burning garlic to prevent bitterness and maintain the dish’s savory balance.

Wilt the Spinach

Add the roughly chopped baby spinach to the skillet and cook just until wilted, about 1 to 2 minutes. This keeps the spinach vibrant and preserves its nutrients, contributing freshness to the casserole.

Combine Chicken, Rice, and Vegetables

In a large mixing bowl, combine the shredded cooked chicken, uncooked rice, sautéed vegetable mixture, crumbled feta, shredded mozzarella, dried oregano, thyme, salt, and black pepper. Thoroughly mixing the ingredients ensures every bite is flavorful and balanced.

Mix Dairy and Broth

In a separate bowl, whisk together the whole milk, sour cream, and chicken broth until smooth. Pour this creamy mixture over the chicken and rice blend, then stir to combine completely. This liquid cooks the rice while infusing creaminess into the casserole.

Transfer Mixture and Level Surface

Pour the combined casserole mixture into the prepared dish and spread it evenly using a spatula. Leveling the surface helps the casserole cook consistently and present nicely after baking.

Add Optional Breadcrumb Topping

If you choose, mix the breadcrumbs with olive oil to create a crispy topping and sprinkle it evenly over the casserole. This adds a delightful crunch that contrasts with the creamy interior.

Bake Covered and Then Uncovered

Cover the casserole snugly with aluminium foil and bake for 30 minutes. Then remove the foil and bake another 15 minutes until bubbling and golden brown on top. The covered phase steams the rice perfectly, while uncovering ensures a beautifully browned crust.

Rest Before Serving

Allow the casserole to rest for 5 to 10 minutes after baking. This helps it set for easy serving and lets the flavors meld further for optimal taste.

You Must Know

  • Shredded cooked chicken works best for even distribution and tender bites.
  • Uncooked rice cooks through during baking, absorbing flavors and liquid perfectly.
  • You can customize vegetables, swapping spinach or peppers based on preference.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain the creamy texture and flavors.

Serving Suggestions

This casserole pairs beautifully with a crisp green salad or roasted Mediterranean vegetables. A side of warm crusty bread or garlic pita can also complete the meal perfectly.

Professional Tips

  • Use freshly crumbled feta for the best tangy flavor and crumbly texture.
  • Cover the casserole tightly during the first baking stage to ensure rice cooks evenly and absorbs all the juices.
  • For extra moisture, you can substitute part of the whole milk with cream or add a splash of white wine for more depth.

FAQs

Can I use brown rice instead of white rice?

Yes, but brown rice will require a longer bake time or pre-cooking as it takes more time to cook through than white rice.

Is this dish freezer friendly?

Yes, you can freeze leftovers for up to 2 months. Thaw overnight in the fridge before reheating thoroughly.

Can I make this casserole vegetarian?

Absolutely. Replace chicken with roasted vegetables or plant-based protein and use vegetable broth instead of chicken broth.

What cheese alternatives can I use?

Feta is key for authentic flavor, but goat cheese or ricotta can be substituted for a different creamy tang.

How do I know when the rice is fully cooked?

The casserole should be bubbling and the rice tender when tested with a fork after baking. If needed, cover and bake longer with extra broth.

Can I prepare this recipe ahead of time?

You can assemble the casserole a few hours ahead and refrigerate before baking to save time on the day of serving.
