Ingredients You’ll Need
These ingredients are simple yet crucial, combining to create that luscious texture and rich flavor that makes the Chicken Alfredo Casserole Recipe so special. Each component plays an essential role, from the tender chicken to the velvety sauce and the melty cheese layers.
- Boneless, skinless chicken breasts: Using bite-sized pieces ensures every forkful has tender protein that absorbs the flavors beautifully.
- Red onion: Adds a subtle sweetness and slight crunch when cooked with the chicken.
- Garlic cloves: Minced garlic infuses a robust aroma and depth to the sauce and chicken mixture.
- Penne pasta: A sturdy pasta shape that holds the creamy sauce perfectly without getting mushy.
- Alfredo sauce: The foundation of the casserole’s creaminess, bringing all the ingredients together.
- Shredded mozzarella cheese: Melts beautifully to create a gooey, stretchy topping and adds creaminess inside.
- Milk: Lightens the Alfredo sauce slightly for perfect consistency.
- Shredded cheddar cheese: Adds a sharper cheesy flavor and a stunning golden crust when baked.
- Salt and freshly ground black pepper: Essential for seasoning and bringing out each ingredient’s natural taste.
- Fresh parsley (optional): A burst of color and freshness to finish the dish.
How to Make Chicken Alfredo Casserole Recipe
Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish. This helps ensure your cheesy masterpiece doesn’t stick and will be easy to serve once baked.
Step 2: Cook the Chicken with Onion and Garlic
In a skillet over medium heat, cook the bite-sized chicken pieces until they are no longer pink, about 5 to 7 minutes. Season them with salt and freshly ground black pepper as they cook to develop flavor. Next, add the chopped red onion and minced garlic, sautéing for another 2 to 3 minutes until fragrant and softened. Then, remove the pan from heat to let those delicious aromas meld.
Step 3: Cook the Pasta Al Dente
While the chicken mixture cools slightly, bring a large pot of salted water to a boil. Cook the penne pasta according to package directions until al dente, so it maintains a slight bite and doesn’t get mushy when baked. Drain the pasta thoroughly to avoid excess water diluting the sauce.
Step 4: Combine Everything for the Casserole
In a large mixing bowl, combine the cooked chicken mixture, drained pasta, Alfredo sauce, one cup of shredded mozzarella cheese, and the milk. Stir everything until evenly coated and creamy, ensuring that every bite will have that indulgent cheesy flavor with succulent chicken and pasta.
Step 5: Assemble and Bake the Casserole
Spread the combined mixture evenly into the prepared casserole dish. Next, sprinkle the remaining shredded mozzarella and the cheddar cheese on top to create a rich, golden layer that will bubble and melt beautifully in the oven.
Step 6: Bake to Perfection
Bake the casserole at 350°F (175°C) for 25 minutes, or until the cheese topping is melted, bubbly, and starting to turn golden. The aroma coming from the oven will be enough to gather everyone eagerly to the table.
Step 7: Rest and Garnish
Let the casserole cool slightly after baking—this helps it set and makes serving easier. Just before serving, sprinkle some fresh chopped parsley over the top for a pop of color and a fresh taste that perfectly balances the creamy richness.

Garnishes
Fresh chopped parsley is a classic and simple garnish that brings brightness and a lovely green contrast to the creamy, cheesy casserole. You can also add a sprinkle of freshly grated Parmesan or cracked black pepper for an extra touch of indulgence.
Side Dishes
This Chicken Alfredo Casserole stands out on its own, but pairing it with crisp, fresh salads like a Caesar or arugula salad adds a wonderful textural contrast. You might also serve it with garlic bread or roasted vegetables for a more substantial meal that complements the creamy richness.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins or small oven-safe dishes to make single-serving portions. This adds a touch of elegance and makes it perfect for dinner parties. Another idea is to top the casserole with breadcrumbs mixed with herbs before baking for added crunch.
Make Ahead and Storage
Storing Leftovers
After enjoying your Chicken Alfredo Casserole Recipe, simply transfer any leftovers to an airtight container and store them in the refrigerator. It will keep well for up to 3 days, making it a fantastic option for quick lunches or dinners later in the week.
Freezing
You can freeze this casserole either before or after baking. If freezing before, assemble the casserole in a freezer-safe dish, cover tightly, and freeze for up to 2 months. When ready to bake, thaw overnight in the refrigerator and bake as directed. If freezing after baking, make sure it has cooled completely, then wrap well before freezing.
Reheating
To reheat, bake leftovers in a preheated oven at 350°F (175°C) until warmed through and bubbly—this usually takes about 15 to 20 minutes. Alternatively, you can microwave individual portions on medium power, stirring halfway to maintain creaminess.
FAQs
Can I use a different type of pasta for the casserole?
Absolutely! While penne is perfect for holding the sauce, other sturdy pastas like rigatoni, rotini, or shells will work just as well. Just ensure the pasta is cooked al dente so it doesn’t become too soft after baking.
Is it possible to make this casserole dairy-free?
Yes, you can substitute the Alfredo sauce with a dairy-free version and use plant-based cheese alternatives. Keep in mind the flavor and texture might vary slightly, but it remains a delicious option for those with dietary restrictions.
How can I make this recipe spicier?
If you crave a little heat, try adding red pepper flakes or diced jalapeños when cooking the chicken and onions. You can also sprinkle some cayenne pepper into the mixture before baking for a subtle kick.
Can leftovers be reheated more than once?
It’s best to only reheat leftovers once to ensure the best flavor and food safety. If you plan on multiple meals, divide the casserole into smaller portions before storing so you can reheat what you need without repeated heating.
What can I add to make this casserole more vegetable-packed?
Adding steamed broccoli florets, sautéed mushrooms, or chopped spinach to the mix is an excellent way to incorporate veggies. Just be mindful of excess moisture—pre-cook and drain vegetables well to avoid a soggy casserole.
