- 1.5 lbs (about 700g) boneless, skinless chicken breasts or thighs, cut into 1-inch chunks
- 1 tablespoon olive oil

- 1 teaspoon dried Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the Garlic Butter Sauce:
- ½ cup (1 stick or 115g) unsalted butter
- 1 whole head of garlic, cloves minced (about 2 tablespoons) – yes, a whole head!

- ⅓ cup (40g) all-purpose flour
- 2 cups (480ml) chicken broth
- 1 cup (240ml) heavy cream or half-and-half for a lighter option
- 1 cup (240ml) whole milk
- 1 teaspoon chicken bouillon powder (optional, for extra depth)
- ½ teaspoon salt, or to taste
- ¼ teaspoon black pepper
For the Casserole Assembly:
- 1 ½ cups (300g) long-grain white rice (like Jasmine or Basmati), uncooked – DO NOT use instant rice

- 1 cup (100g) freshly grated Parmesan cheese, divided
- Fresh parsley or chives, finely chopped for garnish
Step-by-Step Instructions for the Perfect Casserole
Follow these detailed steps for a flawless result every time. We’ll walk you through the process from stovetop to oven.
Step 1: Prepare and Season the Chicken
- Pat the chicken pieces completely dry with paper towels. This is crucial for getting a good sear.
- In a medium bowl, toss the chicken pieces with olive oil, paprika, Italian seasoning, salt, and black pepper. Ensure each piece is evenly coated. Set aside to marinate while you prep the other ingredients.
Step 2: Create the Magnificent Garlic Butter Sauce
This sauce is the heart and soul of the dish.
- Preheat your oven to 375°F (190°C).
- In a large, deep oven-safe skillet or Dutch oven (at least 12 inches in diameter), melt the butter over medium heat.
- Add the diced onion and cook for 3-4 minutes until it begins to soften.
- Add the minced garlic and cook for just 1 minute until fragrant. Be careful not to burn it.
- Sprinkle the flour over the butter, onion, and garlic. Whisk constantly for about 2 minutes. This cooks the raw flour taste out and creates your roux, which will thicken the sauce.
Step 3: Build the Creamy Base
- Gradually pour in the chicken broth while whisking vigorously to prevent any lumps from forming.
- Whisk in the heavy cream and milk until the mixture is smooth.
- Add the optional chicken bouillon powder, salt, and pepper. Bring the sauce to a gentle simmer. It will thicken noticeably as it heats. Let it simmer for 2-3 minutes, then remove from heat.
Step 4: Sear the Chicken & Assemble the Bake
- In a separate large skillet, heat a drizzle of oil over medium-high heat. Add the seasoned chicken in a single layer, working in batches if needed. Sear for 2-3 minutes per side until golden brown. The chicken does not need to be cooked through, as it will finish in the oven. This step adds incredible flavor.
- To the creamy garlic butter sauce in your oven-safe dish, stir in the uncooked white rice.
- Gently fold in the seared chicken pieces and any juices from the pan.
- Stir in 1 cup of the mozzarella cheese and ½ cup of the Parmesan cheese.
Step 5: Bake to Golden-Brown Perfection
- Cover the skillet or Dutch oven tightly with a lid or aluminum foil.
- Carefully transfer it to the preheated oven. Bake covered for 30 minutes.
- After 30 minutes, carefully remove the dish from the oven. The rice should be tender and have absorbed most of the liquid.
- Remove the foil and sprinkle the remaining ½ cup of mozzarella and ½ cup of Parmesan cheese evenly over the top.
- Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is melted, bubbly, and starting to turn golden in spots.
- For an extra-golden top, you can broil for the last 1-2 minutes, but watch it closely!
Step 6: Rest, Garnish, and Serve!
- Once out of the oven, let the casserole rest for 5-10 minutes. This allows the sauce to set slightly, making it easier to serve.
- Garnish generously with freshly chopped parsley or chives.
- Serve hot directly from the dish, and enjoy the rave reviews!
Pro Tips & Helpful Variations for Your Casserole
- The Rice Matters: Always use regular long-grain white rice. Instant or minute rice will turn to mush during the long bake. Rinsing the rice can help prevent excess starchiness, but it’s not strictly necessary for this recipe.
- Chicken Choice: Chicken thighs are more forgiving and will stay juicier, but breasts work perfectly if not overcooked. Ensure pieces are uniform in size for even cooking.
- Garlic Lovers Unite: For an even more intense flavor, add ½ teaspoon of garlic powder to the sauce along with the fresh garlic.
- Add Vegetables: Make this a complete meal by adding 1-2 cups of frozen peas, broccoli florets, or spinach when you stir in the chicken. For softer veggies like mushrooms or bell peppers, sauté them with the onions.
- Storage & Reheating: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave with a splash of broth or milk, or cover and warm in a 300°F (150°C) oven until heated through.
- Make-Ahead Magic: You can assemble the entire casserole (up to the point of the final cheese topping) the night before. Cover and refrigerate. When ready to bake, let it sit at room temperature for 20-30 minutes, then bake covered as directed, adding an extra 5-10 minutes to the covered bake time since it’s starting cold. Add the final cheese and bake uncovered as usual.
