Ingredients

For the Pasta and Chicken

• 1 pound (450 g) penne pasta, rigatoni, or rotini
• 2 tablespoons olive oil
• 2 large boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning

For the Alfredo Sauce

• 6 tablespoons unsalted butter
• 6 cloves garlic, finely minced
• 3 tablespoons all-purpose flour
• 3 cups whole milk
• 1 cup heavy cream
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon onion powder
• ¼ teaspoon nutmeg (optional)
• 2 cups freshly grated Parmesan cheese

For the Topping

• 2 cups shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• 2 tablespoons chopped fresh parsley

Equipment Needed

• Large pot
• Colander
• Large skillet or sauté pan
• Whisk
• Mixing spoon
• 9 x 13-inch baking dish
• Aluminum foil

Step 1: Prepare the Pasta

Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook until just al dente according to the package instructions. Since the pasta will continue cooking in the oven, avoid overcooking it at this stage.

Drain the pasta thoroughly and set aside. If desired, toss it with a small amount of olive oil to prevent sticking while you prepare the remaining ingredients.

Step 2: Cook the Chicken

Heat the olive oil in a large skillet over medium-high heat. Add the diced chicken pieces and season with salt, black pepper, garlic powder, and Italian seasoning.

Cook for 6 to 8 minutes, stirring occasionally, until the chicken is lightly golden and fully cooked through. Remove the chicken from the skillet and set aside.

Step 3: Make the Alfredo Sauce

Using the same skillet, reduce the heat to medium and melt the butter. Add the minced garlic and cook for 30 to 60 seconds until fragrant.

Sprinkle the flour over the butter and garlic mixture. Whisk continuously for 1 to 2 minutes to create a smooth roux and eliminate the raw flour taste.

Gradually pour in the milk while whisking constantly. Add the heavy cream and continue whisking until smooth.

Season with salt, black pepper, onion powder, and nutmeg if using. Allow the mixture to simmer gently for 4 to 6 minutes, stirring frequently, until it begins to thicken.

Reduce the heat to low and gradually add the Parmesan cheese, whisking after each addition until fully melted. Continue stirring until the sauce becomes rich, creamy, and smooth.

Step 4: Combine Everything

Return the cooked chicken to the Alfredo sauce and stir well to coat every piece.

Add the cooked pasta and gently fold everything together until the sauce evenly coats the pasta and chicken. Ensure every piece is covered with the creamy sauce for the best texture and flavor.

Step 5: Assemble the Bake

Preheat the oven to 375°F (190°C).

Lightly grease a 9 x 13-inch baking dish. Transfer the pasta mixture into the dish and spread it into an even layer.

Sprinkle the mozzarella cheese evenly over the top, followed by the remaining Parmesan cheese.

Step 6: Bake

Cover the baking dish loosely with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for an additional 10 to 15 minutes, or until the cheese is melted, bubbly, and lightly golden on top.

For a deeper golden crust, place the dish under the broiler for 2 to 3 minutes at the end of baking, watching carefully to prevent burning.

Step 7: Rest and Serve

Remove the casserole from the oven and let it rest for 5 to 10 minutes before serving. This allows the sauce to settle and makes the casserole easier to serve.

Sprinkle with freshly chopped parsley and serve warm.

Tips for the Best Creamy Chicken Alfredo Bake

Use Freshly Grated Parmesan

Fresh Parmesan melts more smoothly and creates a richer, more authentic Alfredo flavor.

Do Not Overcook the Pasta

Cook the pasta just until al dente so it retains the perfect texture after baking.

Season Every Layer

Seasoning both the chicken and the sauce creates a more balanced and flavorful final dish.

Avoid High Heat

Keep the sauce at a gentle simmer. Boiling can cause dairy-based sauces to separate and become grainy.

Let It Rest

A short resting period improves texture and helps the sauce remain thick and creamy.

Variations

Broccoli Chicken Alfredo Bake

Add 2 cups of lightly steamed broccoli florets before baking for extra nutrition and color.

Bacon Alfredo Bake

Mix in 8 slices of cooked and crumbled bacon for a smoky, savory flavor.

Mushroom Alfredo Bake

Add 8 ounces of sautéed mushrooms to the pasta mixture before transferring it to the baking dish.

Spinach Alfredo Bake

Fold in 3 cups of fresh spinach before baking. The spinach will wilt beautifully in the oven.

Spicy Alfredo Bake

Add ½ teaspoon crushed red pepper flakes and ¼ teaspoon cayenne pepper to the sauce for a subtle kick.

Storage Instructions

Refrigeration

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Freezing

Allow the casserole to cool completely before wrapping tightly and freezing for up to 3 months.

Reheating

Reheat in a 350°F (175°C) oven until heated through. Add a splash of milk or cream if needed to restore creaminess.
