- 2 cups whole milk: A key to achieving that silky, creamy sauce without overpowering the other ingredients.
- 1 cup heavy cream: Elevates the sauce’s richness, making every bite decadently smooth.

How to Make Chicken Alfredo Bake Recipe
Step 1: Preheat and Prepare
Set your oven to 375°F (190°C) to get it ready while you prep the dish. Grease a 3-quart baking dish—this little step ensures your beautiful creation won’t stick and is easy to serve once baked.
Step 2: Cook the Pasta
Boil the penne pasta in salted water until just al dente—you want it to have a little bite since it will continue cooking in the oven. Then, drain and set aside. This is the foundation for your bake and pivotal for the perfect texture.
Step 3: Make the Alfredo Sauce
In a large saucepan over medium heat, melt the butter and add the minced garlic, letting it sauté for 30 seconds to release its glorious fragrance. Whisk in the flour and cook for about a minute to form a smooth roux. Gradually whisk in the whole milk and heavy cream, stirring constantly until the sauce thickens beautifully. Stir in the Parmesan cheese and half a cup of mozzarella until melted and creamy. Season with salt and pepper to elevate the flavors.
Step 4: Combine the Ingredients
In a large bowl, toss together the cooked pasta, diced chicken, and your dreamy Alfredo sauce until everything is luxuriously coated. This mixture is what turns simple ingredients into a sumptuous, comforting dish.
Step 5: Assemble and Bake
Transfer your Alfredo-coated pasta and chicken into the greased baking dish. Sprinkle the remaining 1½ cups of mozzarella cheese evenly over the top to create that irresistible cheese blanket. Bake for 20 minutes, letting the cheese melt and bubble to perfection. For an extra special golden crust, broil it for 2 to 3 minutes at the end—watch closely to avoid burning!
Step 6: Serve and Garnish
Once out of the oven, sprinkle chopped fresh parsley over the hot bake to add a vibrant splash of color and fresh flavor. Serve warm and prepare for compliments on this creamy, cheesy, house-favorite recipe.
How to Serve Chicken Alfredo Bake Recipe

Garnishes
Fresh parsley is classic, but you can also add a sprinkle of freshly cracked black pepper or even a dash of red pepper flakes for a little heat. A light drizzle of high-quality olive oil can also add a silky finish that complements the richness of the dish.
Side Dishes
This Chicken Alfredo Bake pairs wonderfully with crisp, green side salads for balance. Think simple arugula with lemon vinaigrette or a fresh Caesar salad. Steamed or roasted vegetables such as broccoli, asparagus, or green beans also provide great color and texture contrasts.
Creative Ways to Present
For family dinners, bake it in a shallow glass dish so everyone can admire the oozy melted cheese and golden top. For gatherings, consider scooping the bake into individual ramekins or mini cast iron skillets to serve personal portions that look as special as they taste.
Make Ahead and Storage
Storing Leftovers
Let the Chicken Alfredo Bake cool before transferring to an airtight container. Store in the refrigerator for up to 3 days. It’s perfect for quick reheats and still tastes wonderfully creamy and comforting after a day or two.
Freezing
You can freeze this dish either before baking or after it has cooled post-baking. Wrap tightly with foil and place in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until hot and bubbly. To retain creaminess, cover the dish with foil during reheating and remove the foil in the last few minutes to refresh the cheesy crust. Microwaving works too but may make the dish a bit less creamy.
FAQs
Can I use other types of pasta for this Chicken Alfredo Bake Recipe?
Absolutely! Penne is great for holding the sauce, but rigatoni, rotini, or shells are fantastic alternatives thanks to their shape and texture.
What if I don’t have heavy cream?
If heavy cream isn’t on hand, you can substitute with additional whole milk and some cream cheese or a bit of sour cream for richness, though the sauce won’t be quite as velvety.
Is it possible to make this recipe vegetarian?
Yes! Simply omit the chicken and add sautéed mushrooms, spinach, or broccoli to maintain the heartiness and flavor profile of the dish.
How can I make this dish lighter?
To lighten it up, try using half-and-half or whole milk instead of heavy cream, reduce the amount of cheese slightly, and opt for grilled chicken breast without extra added fats.
Can I prepare the entire Chicken Alfredo Bake Recipe ahead of time?
Definitely! You can assemble the dish up to the baking step, cover it tightly, and refrigerate for up to 24 hours before baking. This makes it a perfect meal prep or dinner party time-saver.
