Ingredients You’ll Need
This Chicken Alfredo Rice Casserole Recipe relies on simple but crucial ingredients, each thoughtfully chosen to create layers of flavor and texture. From tender chicken to creamy sauce and hearty rice, these components come together beautifully, giving you a dish that’s as visually inviting as it is delicious.
- Boneless, skinless chicken breasts: The star protein, delivering juicy bites that soak up the creamy sauce perfectly.
- Olive oil: For coating the chicken, adding subtle richness and aiding in browning.
- Garlic powder: Infuses a mild, comforting garlicky warmth into the chicken seasoning.
- Onion powder: Adds a hint of savory depth that complements the garlic beautifully.
- Dried oregano: Brings an herbal brightness that livens the chicken’s flavor.
- Salt and black pepper: Essential seasonings to enhance every element.
- Butter: Used twice—once for cooking rice and once for the Alfredo sauce, lending richness and silkiness.
- Long-grain white rice: Fluffy and light, it soaks up all the creamy goodness just right.
- Chicken broth: Adds savory depth to cook the rice, making it far from bland.
- Minced garlic: Fresh garlic adds an aromatic pop to the Alfredo sauce.
- Heavy cream: Creates the luscious, velvety base of the sauce that hugs every bite.
- Grated Parmesan cheese: Essential for that signature nutty, salty flavor in Alfredo sauce and for topping.
- Nutmeg (optional): A subtle, warm spice that elevates the sauce without overpowering.
- Frozen peas: For color, sweetness, and a pop of fresh green in every forkful.
- Shredded mozzarella cheese: Melts beautifully on top for that bubbly, golden finish.
- Fresh parsley: Adds a fresh, bright garnish that cuts through the richness.
How to Make Chicken Alfredo Rice Casserole Recipe
Step 1: Prepare the Chicken
Start by preheating your oven to 375°F (190°C). If you like, cut your chicken breasts into bite-sized pieces to ensure every forkful includes tender chicken. Toss the chicken in olive oil and a blend of garlic powder, onion powder, dried oregano, salt, and black pepper to build a fragrant, well-rounded base flavor. Bake the chicken until it’s cooked through and juicy, then shred or dice it to create the perfect texture for the casserole.
Step 2: Cook the Rice
While the chicken bakes, melt butter in a medium saucepan over medium heat. Add the uncooked rice and stir it for a couple of minutes to lightly toast the grains—it enhances the texture and flavor. Pour in chicken broth and bring to a boil, then reduce to low, cover, and simmer patiently until the rice is tender and all the liquid has disappeared. Fluff the cooked rice with a fork to keep it light and airy.
Step 3: Make the Alfredo Sauce
Next up is the creamy Alfredo sauce, which is the heart of this Chicken Alfredo Rice Casserole Recipe. Melt butter in a large saucepan, then sauté freshly minced garlic just until fragrant, filling your kitchen with that irresistible aroma. Slowly add heavy cream and let it simmer until thickened to a luscious consistency. Stir in Parmesan cheese, salt, black pepper, and that pinch of nutmeg (if you’re using it) to create a smooth, velvety sauce. Taste and tweak the seasoning to your liking—it’s worth taking the time.
Step 4: Assemble and Bake
Preheat your oven to 350°F (175°C). Combine the baked chicken, cooked rice, Alfredo sauce, and thawed peas in a large bowl, mixing everything together so every bit is coated in creamy goodness. Transfer this mixture to a greased 9×13 inch baking dish, then sprinkle the shredded mozzarella cheese evenly on top. Bake for 20 to 25 minutes until the cheese melts into a bubbly, golden crown and the casserole is heated through. Let it sit for a few minutes before serving so the flavors meld perfectly.
How to Serve Chicken Alfredo Rice Casserole Recipe

Garnishes
Sprinkle fresh chopped parsley over the casserole before serving to add a fresh pop of color and brightness that balances the rich, creamy flavors. A light grating of extra Parmesan on top adds an extra layer of savory indulgence, making each bite even more appealing.
Side Dishes
The creamy, hearty nature of this Chicken Alfredo Rice Casserole Recipe pairs beautifully with lighter sides. Consider a crisp garden salad with a tangy vinaigrette, roasted seasonal vegetables, or even garlic bread to soak up any leftovers of the delicious sauce. These sides complement without competing, letting your casserole shine.
Creative Ways to Present
For a fun twist, serve the casserole in small individual ramekins for a personal touch, perfect for dinner parties or meal prepping. You could also layer it in a transparent baking dish to showcase the colorful peas and melted cheese on top. Adding a sprinkle of toasted breadcrumbs before baking gives an exciting crispy contrast to the creamy middle.
Make Ahead and Storage
Storing Leftovers
This Chicken Alfredo Rice Casserole Recipe reheats beautifully, making it an ideal make-ahead meal. Store your leftovers in an airtight container in the refrigerator for up to 3 to 4 days to maintain freshness and flavor.
Freezing
You can freeze the casserole either before or after baking. If frozen before baking, assemble as usual and cover tightly with foil and plastic wrap to protect against freezer burn. It will keep well for up to 2 months. Thaw overnight in the fridge before baking. If freezing after baking, cool completely and store in a freezer-safe container with a secure lid.
Reheating
To reheat, cover the casserole with foil and warm it in a 350°F (175°C) oven for about 20 minutes or until heated through. For quicker reheating, individual portions can be microwaved, but be sure to stir halfway for even warmth and a creamy finish.
FAQs
Can I use brown rice instead of white rice?
Absolutely! Just keep in mind that brown rice takes longer to cook and requires more liquid. You may want to precook the brown rice before assembling the casserole to ensure an even texture.
Is it possible to make this casserole dairy-free?
Yes, substitute heavy cream with coconut cream or a non-dairy cream alternative, and use dairy-free butter and cheese substitutes. The flavors will vary slightly but still produce a creamy, satisfying result.
Can I add other vegetables to the casserole?
Definitely! Frozen or fresh vegetables like mushrooms, spinach, or broccoli work wonderfully. Just be sure to adjust cooking times so everything is tender and the casserole isn’t too watery.
What can I do if I don’t have nutmeg?
Nutmeg is optional but recommended for warm depth. If you’re out, a tiny pinch of ground white pepper or a touch of ground cinnamon can offer a subtle alternative without overwhelming the dish.
How can I make this recipe spicier?
Try adding a pinch of red pepper flakes to the chicken seasoning or a dash of cayenne to the Alfredo sauce. Just add gradually to keep the heat balanced with the rich creaminess.

Additional Ingredients

Instructions
- Prepare the Chicken: Preheat the oven to 375°F (190°C). Cut the chicken breasts into bite-sized pieces if desired for easier eating.
- Season the Chicken: In a medium bowl, toss the chicken pieces with olive oil, garlic powder, onion powder, dried oregano, salt, and black pepper to evenly coat.
- Bake the Chicken: Place the seasoned chicken in a baking dish and bake for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C). If baked whole, shred or dice the chicken once done.
- Cook the Rice: In a medium saucepan, melt 1 tablespoon of butter over medium heat. Add the uncooked rice and stir constantly for 1-2 minutes to toast slightly.
- Add Broth and Simmer: Pour in the chicken broth and bring it to a boil. Reduce heat to low, cover the pan, and simmer for 18-20 minutes until the rice is tender and the liquid is absorbed. Fluff the rice with a fork and set aside.
- Make the Alfredo Sauce: In a large saucepan, melt 4 tablespoons of butter over medium heat. Add the minced garlic and cook for about 1 minute until fragrant.
- Simmer the Cream: Pour in the heavy cream and bring to a gentle simmer. Reduce heat to low and simmer for 5-7 minutes, stirring occasionally, until the sauce thickens slightly.

Notes

- If you prefer a lighter version, use half-and-half instead of heavy cream, but the sauce may be less rich.
- Use freshly grated Parmesan cheese for better flavor and smoother melting.
- Let the casserole sit for a few minutes after baking to allow it to set for easier serving.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated covered to retain moisture.
