Step‑by‑Step Instructions for Chicken Alfredo Rice Casserole
Step 1: Prepare Chicken
Preheat your oven to 375°F (190°C). In a large mixing bowl, coat the boneless, skinless chicken breasts with olive oil, garlic powder, onion powder, dried oregano, salt, and black pepper. Spread the seasoned chicken on a baking sheet and bake for 20-25 minutes, or until the internal temperature reaches 165°F (74°C). Once cooked, remove from the oven and shred the chicken using two forks.
Step 2: Cook Rice
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add 1 cup of long-grain white rice and toast it for about 2 minutes, stirring constantly until lightly golden. Pour in 2 cups of chicken broth and bring the mixture to a boil. Reduce the heat to low, cover, and simmer for 15-20 minutes until the liquid is absorbed and the rice is fluffy.
Step 3: Make Alfredo Sauce
In a large skillet, melt another 2 tablespoons of butter over medium heat. Add minced garlic and sauté for about 1 minute, until fragrant. Pour in 1 cup of heavy cream and let it simmer gently for 5-7 minutes, allowing it to thicken slightly. Stir in 1 cup of grated Parmesan cheese, then season with additional salt and pepper to taste, allowing the sauce to fully blend.
Step 4: Assemble Casserole
In a large mixing bowl, combine the shredded chicken, cooked rice, Alfredo sauce, and 1 cup of frozen peas. Mix everything together until evenly coated. Transfer this mixture into a greased 9x13-inch baking dish, spreading it evenly across the bottom.
Step 5: Bake
Sprinkle 1 cup of shredded mozzarella cheese evenly over the top of the casserole. Place the baking dish in the preheated oven and bake at 350°F (175°C) for 20-25 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and lightly golden on top.
Step 6: Serve
Remove the casserole from the oven and let it cool for about 5 minutes. Garnish with fresh chopped parsley for added flavor and color. Serve warm and enjoy the creamy Chicken Alfredo Rice Casserole with your favorite side dishes!

Chicken Alfredo Rice Casserole Recipe FAQs
What type of chicken should I use?
For the best texture and flavor, I recommend using boneless, skinless chicken breasts. They remain tender and juicy throughout the baking process. If you prefer dark meat, boneless chicken thighs can also be a flavorful substitute, but just make sure to adjust the cooking time accordingly.
How should I store leftover Chicken Alfredo Rice Casserole?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Ensure the casserole cools down completely before sealing it to maintain moisture and prevent sogginess. For the ultimate convenience, you can reheat individual portions in the microwave or oven until warm.
Can I freeze the Chicken Alfredo Rice Casserole?
Absolutely! This casserole freezes wonderfully. To freeze, let it cool completely, then tightly wrap it in plastic wrap and aluminum foil, labeling the date. It can be stored in the freezer for up to 3 months. Thaw it in the fridge overnight before baking, or follow the reheating instructions straight from the freezer for a cozy meal on demand!
What if my Alfredo sauce is too thick?
If you find your Alfredo sauce has thickened too much, simply add a splash of chicken broth or milk to loosen it up. Return it to the heat and stir until well combined. If you're starting from scratch, watch your simmering time closely—simmer for less time for a thinner sauce and add more cheese for richness.
Is this casserole suitable for vegetarians?
Yes, it can easily be made vegetarian! Substitute the chicken with plant-based chicken alternatives or vegetables such as sautéed mushrooms and spinach. Use vegetable broth instead of chicken broth and replace the cheese with vegan alternatives. It's a comforting and hearty option everyone can enjoy!
How can I tell when the casserole is done baking?
The casserole is ready when the top is golden and bubbly, generally taking about 20-25 minutes at 350°F (175°C). You can check if the internal temperature reaches at least 165°F (74°C) for safe serving. Let it cool for a few minutes before serving to allow the layers to set beautifully.
