Ingredients You’ll Need
This Chicken Alfredo Casserole Recipe works its magic with simple, familiar ingredients that create irresistible flavor and comfort. Each element brings something special, from the gooey cheese to the aromatic garlic, resulting in a dish that’s so much more than the sum of its parts.
- Chicken: Use 3 cups of cooked, shredded or diced chicken for heartiness and easy prep—rotisserie chicken is a time-saver!
- Pasta: 12 ounces of penne or rotini gives the casserole great texture and holds onto all that creamy sauce.
- Alfredo Sauce: 3 cups, homemade or store-bought, lend creaminess and luscious flavor to every bite.
- Mozzarella Cheese: 1 ½ cups, shredded, melts beautifully on top for that classic cheese pull.
- Parmesan Cheese: ½ cup grated, adds a deep, savory flavor and helps the topping brown.
- Broccoli Florets: 1 cup steamed (optional), sneaks in extra veggies while pairing perfectly with chicken and cheese.
- Garlic: 2 cloves, minced for vibrant, aromatic depth.
- Italian Seasoning: 1 teaspoon for classic herby notes that tie all the flavors together.
- Salt: ½ teaspoon to enhance all the other ingredients.
- Black Pepper: ¼ teaspoon for just a touch of warmth.
- Olive Oil: 1 tablespoon helps sauté the garlic and prevents sticking.
- Chopped Parsley: For garnish (optional), offers a pop of color and freshness at the end.
How to Make Chicken Alfredo Casserole Recipe
Step 1: Prep Your Oven and Baking Dish
Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a little olive oil or nonstick spray. This prevents sticking and sets the stage for an effortlessly creamy casserole.
Step 2: Cook the Pasta Perfectly
Bring a large pot of salted water to a boil and cook your penne or rotini until al dente. You want the pasta to be firm to the bite so it won’t become mushy after baking. Drain it well and set aside—it’s about to get enveloped in a creamy dream.
Step 3: Sauté and Build Flavor
Heat olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about a minute, just until fragrant. Now toss in the cooked chicken, steamed broccoli (if you’re including it), salt, pepper, and Italian seasoning. Give everything a quick stir to warm through. Pour in the Alfredo sauce and let it simmer for 2 to 3 minutes, so those flavors meld beautifully.
Step 4: Combine and Assemble
In a large mixing bowl, combine the cooked pasta with your creamy sauce mixture. Stir gently until every noodle is coated and every piece of chicken is tucked into that cheesy sauce. Pour the whole glorious mixture into your prepared baking dish and spread it into an even layer.
Step 5: Cheese and Bake
Sprinkle the mozzarella and Parmesan cheeses evenly over the top. Cover the casserole tightly with foil and bake for 20 minutes. Then, remove the foil and bake for another 10 to 15 minutes until the cheese is bubbly and gloriously golden-brown. Your kitchen will smell incredible!
Step 6: Garnish and Serve
Once out of the oven, let the casserole cool for just a few minutes, then shower it with chopped parsley if you like. That little burst of green adds freshness and flair to your finished dish.

Garnishes
Fresh parsley is a classic choice to sprinkle over your Chicken Alfredo Casserole Recipe, lending color and a hit of freshness. For an extra touch, a sprinkle of additional Parmesan or a light dusting of cracked black pepper can elevate each serving. If you want to get fancy, a drizzle of extra-virgin olive oil across the top just before serving really seals the deal on flavor.
Side Dishes
This hearty casserole is delicious enough to stand alone, but pairing it with simple sides takes your dinner to restaurant-worthy levels. Think crisp Caesar salad, a platter of roasted vegetables, or a basket of warm garlic bread. Each side blends seamlessly with the rich flavors while offering a bit of contrast in texture and taste.
Creative Ways to Present
The Chicken Alfredo Casserole Recipe is versatile enough for every occasion. Spoon it into individual ramekins for dinner parties or serve straight from the baking dish for a cozy family meal. If you’re feeling festive, top each serving with a little extra cheese and pop it under the broiler for a five-star finishing touch.
Make Ahead and Storage
Storing Leftovers
Leftovers of this casserole keep beautifully. Transfer any remaining Chicken Alfredo Casserole Recipe to an airtight container and store it in the refrigerator for up to 3 days. The flavors meld even more overnight, so don’t be surprised if everyone’s eyeing those leftovers for lunch!
Freezing
You can absolutely freeze this casserole for ultimate convenience. Simply assemble the dish right up to the baking stage, cover tightly, and freeze for up to 2 months. Thaw overnight in the fridge before baking as directed. For best results, wait to add the cheese topping until just before baking.
Reheating
To reheat, cover the dish with foil and warm it in a 350°F oven until hot throughout (about 20 minutes). Individual portions can be microwaved in a covered dish—just add a splash of milk or cream to revive that creamy texture. The cheese will melt again, and your casserole will taste freshly made.
FAQs
Can I make the Chicken Alfredo Casserole Recipe ahead of time?
Absolutely! Assemble the casserole right up to the point before baking, cover and refrigerate. When you’re ready, just bake as directed—add a few extra minutes if it’s coming straight from the fridge.
What type Main Course
Any cooked chicken will do, but rotisserie chicken is a lifesaver on busy nights. Grilled, baked, or even leftover roasted chicken all work wonderfully and add a variety of flavors to your casserole.
Can I add other vegetables?
Definitely! While broccoli is classic, feel free to stir in sautéed mushrooms, cooked spinach, or even peas. This Chicken Alfredo Casserole Recipe is flexible enough to handle your favorite additions.
Is it possible to use a different cheese?
Yes, if you’re looking to mix things up, try a blend of mozzarella with fontina or provolone for even gooier results. Just be sure to include enough Parmesan for that signature umami kick.
How can I make this dish lighter?
Swap in a lighter Alfredo sauce or use part-skim cheeses. Adding extra veggies and using whole-wheat or chickpea pasta are other great ways to up the nutrition while keeping every bite delicious.
