- Cooked white or brown rice (2 cups): This forms the base, soaking up all that creamy sauce and adding satisfying texture.

- Frozen peas (1 cup): Adds color, sweetness, and a little pop to every bite.
- Shredded mozzarella cheese (1 cup): Melts into gooey goodness and helps bind the casserole.
- Grated Parmesan cheese (½ cup): For a sharp, savory finish and that irresistible cheesy crust.
- Garlic powder (1 teaspoon): Brings a subtle depth and warmth without overpowering the sauce.
- Black pepper (½ teaspoon): Adds gentle heat and balances the creaminess.
- Salt (¼ teaspoon, optional): Taste first—sometimes the Alfredo and cheeses provide plenty!
- Italian seasoning (½ teaspoon): Infuses the casserole with classic herb flavor and a hint of nostalgia.
- Milk (½ cup): Loosens the sauce and keeps everything extra creamy as it bakes.
- Butter (1 tablespoon): For greasing the dish—helps prevent sticking and adds flavor around the edges.
- Chopped fresh parsley (optional): Sprinkled on top for a fresh, vibrant finish.
How to Make Chicken Alfredo Rice Casserole: The Ultimate Comfort Food Recipe
Step 1: Preheat and Prep
Start by heating your oven to 375°F. Take a moment to lightly grease your baking dish with butter—this not only prevents sticking but also gives the edges of your casserole a subtle richness. A 9×9-inch dish works perfectly, but any similar-size pan will do.
Step 2: Mix the Casserole Base
Grab your largest mixing bowl and combine the cooked rice, chicken, Alfredo sauce, frozen peas, mozzarella, Parmesan, garlic powder, black pepper, Italian seasoning, and milk. Stir gently but thoroughly, making sure every grain of rice and piece of chicken is enveloped in that creamy, cheesy goodness. Taste the mixture and add salt if needed—remember, your cheeses and sauce might already be salty.
Step 3: Assemble in the Baking Dish
Pour the mixture into your prepared baking dish, spreading it out evenly with a spatula. For extra decadence, sprinkle a little more mozzarella and Parmesan over the top. This step guarantees a golden, bubbly crust that’s everyone’s favorite part!
Step 4: Bake to Perfection
Slide the casserole into the oven and let it bake for 25 to 30 minutes. You’ll know it’s ready when the top is golden brown, the edges are bubbly, and your kitchen smells absolutely amazing. Don’t forget to let it rest for five minutes before serving—this helps everything set and makes it easier to scoop.
Step 5: Garnish and Serve
Just before serving, sprinkle over some chopped fresh parsley for a burst of color and freshness. Then, dig in and enjoy the magic of Chicken Alfredo Rice Casserole: The Ultimate Comfort Food Recipe!
