How to Make Dump-and-Bake Chicken Alfredo Rice Casserole Recipe
Step 1: Preheat and Prepare
First, set your oven to 350°F (175°C) to get it ready for cooking this one-dish wonder. Lightly grease a 9×13-inch baking dish with olive oil or cooking spray—this keeps everything from sticking and adds a subtle richness to the casserole base.
Step 2: Mix the Creamy Base
In a large bowl, combine the uncooked long grain white rice, chicken broth, heavy cream, minced garlic, salt, black pepper, and Italian seasoning. Stir everything gently but thoroughly until all those flavors start blending together, creating a luscious, creamy mixture that will soak into the rice during baking.
Step 3: Layer the Ingredients
Pour the creamy rice mixture into your prepared baking dish, spreading it out evenly to ensure consistent cooking. Then, distribute the diced or shredded cooked chicken over the top, followed by an even scatter of fresh broccoli florets and chopped sun-dried tomatoes. These layers not only create delicious texture but also bring bursts of flavor and color to the dish.
Step 4: Top with Cheese
Sprinkle the shredded mozzarella and grated Parmesan cheeses evenly over the entire casserole. The cheese will melt into a golden, bubbly crust that’s impossible to resist—making this part so satisfying as you peek through the oven door.
Step 5: Bake Covered
Cover the baking dish tightly with aluminum foil and pop it in the oven. Bake for 40 minutes to allow the rice to absorb the liquid and the chicken and vegetables to heat through. This step lets the flavors meld beautifully while keeping the moisture locked in.
Step 6: Uncover and Finish Baking
After those 40 minutes, remove the foil and bake for an additional 15 to 20 minutes. This final stretch lets the cheese brown and bubble to perfection, while the rice becomes tender and the casserole develops that iconic golden top.
Step 7: Rest and Garnish
Once baked, let the casserole rest for about 5 minutes before serving. This short pause helps everything set up, making it easier to scoop and enhancing the flavors. If you love a fresh, herbaceous note, sprinkle chopped parsley on top for a gorgeous finishing touch.
How to Serve Dump-and-Bake Chicken Alfredo Rice Casserole Recipe

Garnishes
Fresh parsley is a classic choice that adds a pop of green and a hint of brightness against the creamy richness of the casserole. If you want a bit more zing, a light drizzle of balsamic glaze or some crushed red pepper flakes can elevate the dish further without overpowering it.
Side Dishes
This casserole is a full meal on its own, but pairing it with a crisp green salad or some roasted veggies adds freshness and balance. Garlic bread or crusty rolls also complement the creamy textures perfectly, giving you options to suit the occasion or your mood.
Creative Ways to Present
Serve the casserole straight from the baking dish for family-style comfort. For a fancier touch, portion it onto individual plates and garnish each with a little extra cheese and fresh herbs. You can also turn it into a potluck hit by baking it in a decorative casserole dish and bringing it to share with friends—the Dump-and-Bake Chicken Alfredo Rice Casserole Recipe always impresses!
Make Ahead and Storage
Storing Leftovers
Once cooled, cover leftovers tightly with plastic wrap or transfer to an airtight container and refrigerate for up to 3 days. The flavors tend to deepen overnight, making for a delicious next-day meal.
Freezing
This casserole freezes beautifully. Prepare and bake it as directed, then let it cool completely before wrapping it well in foil or transferring to a freezer-safe container. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating.
Reheating
To reheat, warm individual servings in the microwave or reheat the whole casserole covered with foil in a 350°F oven until heated through, about 20-25 minutes. Adding a splash of chicken broth or cream before reheating can help maintain that creamy texture.
FAQs
Can I use brown rice instead of white rice?
Yes, you can substitute brown rice, but keep in mind it requires a longer cooking time and more liquid. It’s best to pre-cook the brown rice before assembling the casserole to ensure it’s tender.
Is it possible to make this recipe vegetarian?
Absolutely! Simply replace the chicken with extra vegetables like mushrooms or zucchini and use vegetable broth instead of chicken broth to keep it flavorful while vegetarian-friendly.
Can I use uncooked chicken instead of cooked chicken?
You can, but it requires adjusting the cooking time and possibly more liquid. For guaranteed tenderness and ease, cooked chicken is recommended, especially shredded rotisserie chicken for convenience.
What can I substitute for heavy cream?
If you want a lighter option, half-and-half can work, though the casserole will be less rich. For dairy-free versions, try coconut cream or a creamy plant-based milk blend, but flavor and texture may vary slightly.
How do I know when the casserole is fully cooked?
The rice should be tender and fully cooked through, which usually happens after the covered baking time plus the uncovered baking. The cheese will be golden and bubbly, and the casserole should be hot and bubbly in the center when it’s done.
