How to Make Chicken Alfredo Casserole Recipe
Step 1: Preheat Oven and Prepare Your Baking Dish
Start by preheating your oven to 350°F and generously spraying a 9×13-inch baking dish with nonstick cooking spray. This sets the stage for your casserole to come together smoothly without sticking.
Step 2: Cook the Penne Pasta
Cook the penne pasta according to the package instructions until it’s al dente—firm but tender. Drain it well to avoid a soggy casserole and set it aside for later mixing with the sauce and chicken.
Step 3: Brown the Chicken
Heat olive oil in a skillet over medium heat and add the cubed chicken breasts, seasoning them with salt and pepper. Cook until they’re golden on the outside and fully cooked through, about 7-10 minutes. Once done, remove the chicken from heat and set it aside.
Step 4: Whip Up the Creamy Alfredo Sauce
In a large bowl, combine the Alfredo sauce, softened cream cheese, whole milk, minced garlic, Italian seasoning, salt, and black pepper. Stir everything together until the sauce is luxuriously smooth and creamy, building layers of flavor.
Step 5: Mix Pasta, Chicken, and Sauce
Add the cooked pasta and chicken into the creamy sauce, folding until every piece is beautifully coated. Then, stir in half of the shredded mozzarella and half of the grated Parmesan to infuse the mixture with gooey, cheesy goodness.
Step 6: Assemble and Bake the Casserole
Spoon the mixture into your prepared baking dish, spreading it evenly. Sprinkle the remaining mozzarella and Parmesan cheese across the top for that irresistible golden crust. Cover with foil and bake for 25 minutes. Remove the foil and bake uncovered for an additional 10 minutes, or until the cheese is melted, bubbly, and slightly browned.
Step 7: Garnish and Enjoy
Once baked, sprinkle with chopped fresh or dried parsley to add a fresh touch of color and flavor. Serve this creamy, cheesy Chicken Alfredo Casserole Recipe hot for the ultimate comforting meal.
How to Serve Chicken Alfredo Casserole Recipe

Garnishes
A sprinkle of fresh parsley or even some cracked black pepper on top not only brightens the dish but also adds a lovely contrast to that rich creaminess. Feel free to add a pinch of red pepper flakes if you want to bring a little heat to every bite.
Side Dishes
This casserole pairs wonderfully with crisp green salads, steamed broccoli, or roasted asparagus to add freshness and balance out the indulgence. A crusty garlic bread or warm dinner rolls are fantastic options to scoop up every last bit of sauce.
Creative Ways to Present
For dinner parties or special occasions, serve the casserole in individual ramekins for a personalized touch. You can also layer it with some sun-dried tomatoes or sautéed mushrooms to surprise your guests with delightful variations on this beloved Chicken Alfredo Casserole Recipe.
Make Ahead and Storage
Storing Leftovers
After enjoying your meal, place leftovers in an airtight container and store them in the refrigerator. They will keep well for about 3 to 4 days, preserving all the cheesy richness and tender chicken you love.
Freezing
This casserole freezes beautifully! Wrap it tightly or transfer leftovers to a freezer-safe container. It can be frozen for up to 2 months without any loss in texture or flavor, making it perfect for meal planning or last-minute meals.
Reheating
To reheat, defrost overnight in the fridge (if frozen) and warm in the oven at 350°F until bubbly and heated through, about 20 minutes. Alternatively, microwave individual portions until hot, stirring occasionally to ensure even warming.
FAQs
Can I use a different type of pasta?
Absolutely! While penne works great because it holds sauce well, you can substitute with rigatoni, fusilli, or even shells. Just be sure to cook the pasta al dente to avoid mushiness in the casserole.
Is it possible to make this dish vegetarian?
Yes! Simply omit the chicken and consider adding vegetables like mushrooms, spinach, or artichokes to maintain hearty texture and flavor in the Chicken Alfredo Casserole Recipe.
Can I prepare this casserole ahead of time?
Definitely. You can assemble the casserole a day before baking, cover tightly, and refrigerate it. When ready, bake as instructed, adding a few extra minutes if baking straight from the fridge.
What if I don’t have cream cheese?
While cream cheese lends extra creaminess, you can substitute with an equal amount of mascarpone or even ricotta cheese. The texture will be just as luscious, though mascarpone offers a slightly sweeter note.
How do I know when the casserole is done?
You’ll see the cheese bubbling vigorously around the edges, and the top will have a golden, slightly browned crust. This is the perfect signal that your Chicken Alfredo Casserole Recipe is ready to enjoy.
