Ingredients You’ll Need
The beauty of this Chicken Alfredo Casserole Recipe lies in its simple but essential ingredients. Each one plays a crucial role: from the juicy chicken adding protein, to the creamy Alfredo sauce that ties everything together with indulgence, to the blend of cheeses creating that perfect golden crust. These ingredients are easy to find and quick to put together, making this dish both accessible and impressive.
- 3 boneless, skinless chicken breasts: Cut into bite-sized pieces for even cooking and easy bites.
- 1 small red onion: Chopped finely to add a sweet, mild crunch that enhances the flavor.
- 3 cloves garlic: Minced to infuse the dish with aromatic depth and a delicious savory kick.
- 16 oz (450g) penne pasta: Cooked al dente to provide the perfect firm texture that holds the sauce well.
- 15 oz (425g) jar Alfredo sauce: The creamy foundation of the casserole that envelops every element in flavor.
- 1½ cups shredded mozzarella cheese, divided: Blended for both melty interior richness and a stretchy, cheesy topping.
- ¼ cup milk: Added to loosen the sauce slightly and ensure a luscious consistency.
- 1 cup shredded cheddar cheese: Sprinkled on top for a sharp finish and appealing golden color.
- Salt and freshly ground black pepper: To taste, enhancing and balancing all the flavors.
- Fresh parsley, chopped (optional): For a pop of color and fresh herbal brightness as a garnish.
How to Make Chicken Alfredo Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) and lightly greasing a 9×13-inch casserole dish. This prep ensures your casserole cooks evenly and doesn’t stick, setting the stage for the perfect bake.
Step 2: Cook the Chicken Mixture
In a skillet over medium heat, cook the chopped chicken breasts until they lose their pink color, about 5 to 7 minutes. Season generously with salt and freshly ground pepper. Toss in the chopped red onion and minced garlic, cooking for just another 2 to 3 minutes so their flavors meld without overpowering the chicken. Then remove the skillet from heat to let everything rest.
Step 3: Perfect Your Pasta
Bring a large pot of salted water to a boil and cook the penne pasta according to the package instructions until it is just al dente. This means it should be tender but still have a firm bite, so it won’t get mushy after baking. Drain the pasta thoroughly to prevent excess water from diluting your sauce.
Step 4: Combine the Ingredients
In a large mixing bowl, marry together the cooked chicken mixture, the drained penne, the Alfredo sauce, 1 cup of shredded mozzarella, and the milk. Stir everything carefully but thoroughly to ensure every bit of pasta is coated with that rich sauce and every piece of chicken is nestled inside cheesy goodness.
Step 5: Assemble and Top
Spread this creamy chicken and pasta mixture evenly into your prepared casserole dish. Then sprinkle the remaining mozzarella and the cheddar cheese on top in an even layer. This cheese topping will melt and bubble, creating a gorgeous golden crust that’s impossible to resist.
Step 6: Bake to Perfection
Place the filled casserole dish in the preheated oven and bake for about 25 minutes, or until the cheese on top has melted completely and is golden and bubbling. This bake step melds all the flavors and textures, turning your ingredients into a cohesive and decadent dish.
Step 7: Let It Rest and Serve
Once baked, allow the casserole to cool for a few minutes so it sets slightly and is easier to serve. Sprinkle some freshly chopped parsley if you like a fresh herbal contrast and a touch of color. Now your Chicken Alfredo Casserole Recipe is ready to be enjoyed!
How to Serve Chicken Alfredo Casserole Recipe
Garnishes
A sprinkle of fresh parsley is a classic way to brighten the rich flavors and add a lovely pop of green that makes the dish feel fresh. You can also add a little cracked black pepper on top for a hint of spice and visual appeal. For an extra touch, a grating of Parmesan cheese just before serving enhances the cheesy depth even more.
Side Dishes
This casserole is wonderfully filling, but pairing it with crisp, refreshing sides balances the creamy richness. Consider a simple mixed green salad dressed with a tangy vinaigrette or roasted seasonal vegetables such as Brussels sprouts or asparagus to bring freshness and texture contrast to the meal.
Creative Ways to Present
Serve this casserole straight from the baking dish for that comforting, homey feel, or scoop individual portions onto plates garnished with fresh herbs. For a touch of elegance, add a wedge of lemon on the side to brighten each bite with a light citrus burst. If you’re hosting friends, bake in small ramekins for personalized servings that look stunning on the table.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers in an airtight container in the refrigerator. The casserole will stay fresh for up to 3 days, retaining its creamy texture and cheesy flavor, making for an easy next-day meal.
Freezing
This Chicken Alfredo Casserole Recipe freezes beautifully. Assemble the casserole but don’t bake it, then wrap it tightly in plastic wrap followed by foil before freezing. It can be stored frozen for up to 2 months. When ready to eat, thaw overnight in the fridge and bake as directed, adding a few extra minutes to the cooking time if still chilled.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through to preserve that delicious baked texture. You can also microwave individual portions, but be aware the cheese crust might lose some of its crispness. Adding a splash of milk before reheating helps keep the sauce creamy and smooth.
FAQs
Can I use a different type of pasta?
Absolutely! While penne is perfect for holding the sauce, other pasta shapes like rigatoni, rotini, or fusilli work well and offer some variety. Just be sure to cook it al dente so it doesn’t become mushy after baking.
Is it possible to make this recipe vegetarian?
Yes! Simply omit the chicken and add your favorite vegetables like broccoli florets, mushrooms, or spinach. You might want to sauté the veggies first for a richer flavor. This way, you can enjoy the creamy Alfredo goodness without the meat.
Can I use homemade Alfredo sauce?
Definitely! Homemade Alfredo sauce adds a personal touch and can be customized with extra cheese or herbs. Just make sure it’s thick enough to hold its place in the casserole without making it too runny.
How can I make this dish spicier?
For a little heat, add crushed red pepper flakes to the chicken while cooking or mix in some diced jalapeños into the casserole. Alternatively, a dash of hot sauce on top before serving makes a nice spicy kick that contrasts beautifully with the creamy sauce.
What cheese can I substitute if I don’t have mozzarella or cheddar?
Pepper jack, gouda, or Monterey jack are great alternatives that melt well and add delicious flavor. You can experiment with your favorite melting cheeses to find a combination that suits your taste.

This Chicken Alfredo Casserole Recipe is truly a slice of comfort food heaven that’s both easy to prepare and endlessly satisfying.
