Ingredients You’ll Need
Gathering the right ingredients is the secret to making this Chicken Alfredo Casserole Recipe shine. Each component plays an essential role, from the creamy Alfredo sauce that coats the pasta to the golden mozzarella topping that gives it that irresistible finish.
- 2 cups cooked chicken: Shredded or diced, this adds protein and heartiness to the dish.
- 12 oz pasta (penne or rotini recommended): These shapes hold the sauce beautifully and offer great texture.
- 2 cups Alfredo sauce: Creamy and dreamy, homemade or store-bought both work wonders.
- 1 cup mozzarella cheese, shredded: Creates a gooey, melty layer on top.
- 1/2 cup Parmesan cheese, grated: Adds a sharp, nutty flavor that complements the creaminess.
- 1 cup frozen peas (optional): For a pop of color and a subtle sweetness that balances the richness.
- 1 tbsp olive oil: Helps sauté the garlic and chicken, infusing flavor.
- 1 clove garlic, minced: Infuses the dish with fragrant warmth.
- 1/2 tsp salt: Enhances all the natural flavors.
- 1/4 tsp black pepper: Adds a gentle, spicy kick.
- 1/4 tsp Italian seasoning: Brings a herbaceous, Mediterranean flair.
- 1/4 cup fresh parsley, chopped (optional garnish): Brightens up the casserole visually and adds fresh herbal notes.
How to Make Chicken Alfredo Casserole Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. This prep lets you jump straight into assembling the casserole without scrambling later.
Step 2: Cook the Pasta
Boil your pasta until it’s al dente according to the package directions. Drain it well and set it aside so it’s ready to absorb all the creamy goodness to come.
Step 3: Sauté the Garlic
Warm olive oil in a skillet over medium heat, then toss in minced garlic and sauté for about a minute until it’s fragrant and golden, which lays the flavor foundation for the whole casserole.
Step 4: Cook the Chicken with Seasoning
Add the cooked chicken, salt, black pepper, and Italian seasoning to the skillet. Stir it around for about two minutes to let the flavors meld and the chicken heat through.
Step 5: Combine Everything
In a large mixing bowl, gently fold together the cooked pasta, Alfredo sauce, the chicken mixture, and the peas if you’re using them. This ensures every piece is coated in creamy, flavorful sauce.
Step 6: Assemble the Casserole
Transfer your mixture into the baking dish, spreading it out evenly. Then sprinkle the shredded mozzarella and grated Parmesan cheeses generously on top—these create that irresistible cheesy crust.
Step 7: Bake Until Bubbly
Pop the dish into the oven and bake for 25 to 30 minutes until the cheese is melted and bubbly, turning a beautiful golden brown that signals it’s ready.
Step 8: Cool and Garnish
Let the casserole rest for about five minutes after baking so it sets up for perfect slicing. Sprinkle freshly chopped parsley on top for a fresh burst of color and flavor just before serving.
How to Serve Chicken Alfredo Casserole Recipe

Garnishes
Fresh parsley does wonders to lift this decadent dish with its herbaceous brightness. A light drizzle of olive oil or a few twists of black pepper can add an extra inviting touch right before serving.
Side Dishes
Since the casserole is rich and filling, pairing it with crisp green salads or roasted vegetables balances the plate nicely. Garlic bread or a warm baguette also makes a perfect companion to scoop up every delicious bit.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for personal portions or layer it with spinach or mushrooms for added texture and nutrients. You can even sprinkle some red pepper flakes if you like a bit of heat.
Make Ahead and Storage
Storing Leftovers
Store any leftover Chicken Alfredo Casserole Recipe in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making for even tastier leftovers.
Freezing
This casserole freezes beautifully. Just let it cool completely, cover tightly with foil or plastic wrap, then place it in the freezer for up to 2 months. Thaw overnight before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through to maintain that gooey, baked texture. Alternatively, microwave in shorter bursts to avoid drying out, covering the dish to keep moisture in.
FAQs
Can I use a different type of pasta?
Absolutely! While penne and rotini hold the sauce nicely, feel free to use any pasta shape you love or have on hand. Just be sure to cook it al dente to avoid mushiness after baking.
Is homemade Alfredo sauce better than store-bought?
Homemade Alfredo sauce can add a personal touch with fresh ingredients and adjustable seasoning, but good quality store-bought sauce also works well for convenience without sacrificing flavor.
Can I add vegetables to the casserole?
Yes! Frozen peas are a great choice, but you can also try broccoli, spinach, or mushrooms. Just sauté them lightly before mixing to get rid of excess moisture.
What should I do if I don’t have mozzarella?
If mozzarella isn’t available, mild provolone, Monterey Jack, or even a sharp cheddar can be delicious substitutes to get that melty cheesy topping.
How spicy is this dish?
This Chicken Alfredo Casserole Recipe is mild and creamy, perfect for all palates. You can always add red pepper flakes or cayenne pepper if you prefer a spicy kick!
