Preparation Time

Preparation Time: 25 minutes

Cooking Time: 35 minutes

Total Time: About 1 hour

Servings: 6 to 8

Ingredients

For the Chicken:

2 pounds boneless, skinless chicken breasts, cut into bite-sized pieces

1 teaspoon salt

1 teaspoon black pepper

1 teaspoon garlic powder

1 teaspoon onion powder

1 teaspoon Italian seasoning

2 tablespoons olive oil

For the Pasta:

12 ounces fettuccine, penne, or rotini pasta

Water for boiling

1 tablespoon salt for the pasta water

For the Alfredo Sauce:

4 tablespoons butter

4 cloves garlic, finely minced

3 cups heavy cream

1 cup whole milk

1 teaspoon salt

½ teaspoon black pepper

½ teaspoon Italian seasoning

1½ cups freshly grated Parmesan cheese

1 cup shredded mozzarella cheese

For Assembly:

1 cup shredded mozzarella cheese

½ cup grated Parmesan cheese

2 tablespoons chopped fresh parsley

Instructions

Begin by preheating your oven to 375 degrees Fahrenheit. Lightly grease a large baking dish with butter or cooking spray and set it aside.

Bring a large pot of water to a rolling boil. Add the tablespoon of salt and then the pasta. Cook the pasta until it is just shy of al dente. Because the pasta will continue cooking in the oven, slightly undercooking it helps maintain the perfect texture. Drain the pasta and set it aside.

While the pasta cooks, prepare the chicken. Place the chicken pieces in a bowl and season them with salt, pepper, garlic powder, onion powder, and Italian seasoning. Toss everything together until the chicken is evenly coated.

Heat the olive oil in a large skillet over medium-high heat. Add the chicken pieces in a single layer. Cook for several minutes, stirring occasionally, until the chicken is golden and fully cooked through. Remove the chicken from the pan and set it aside.

Using the same skillet, lower the heat to medium and add the butter. Once the butter melts, add the minced garlic and cook for about one minute. Stir constantly to prevent the garlic from browning.

Slowly pour in the heavy cream and milk. Stir continuously until the liquids are combined and gently simmering. Add the salt, pepper, and Italian seasoning. Let the sauce cook for several minutes until it begins to thicken slightly.

Reduce the heat to low and gradually add the Parmesan cheese. Stir continuously until the cheese completely melts and the sauce becomes smooth and creamy. Add the mozzarella cheese and continue stirring until fully incorporated.

Add the cooked chicken to the Alfredo sauce and stir gently. Then add the cooked pasta and carefully fold everything together until every piece of pasta is coated in the creamy sauce.

Transfer the mixture into the prepared baking dish. Spread it evenly so the ingredients are distributed throughout the dish.

Sprinkle the remaining mozzarella cheese over the top, followed by the Parmesan cheese. The cheese topping will melt beautifully and create a lightly golden crust during baking.

Place the dish into the preheated oven and bake for approximately 25 to 30 minutes, or until the casserole is hot and bubbling around the edges and the cheese on top is melted and lightly browned.

Remove the baking dish from the oven and allow it to rest for about 10 minutes before serving. Resting gives the sauce time to settle and makes serving easier.

Sprinkle freshly chopped parsley over the top just before serving.

Tips for the Best Creamy Chicken Alfredo Bake

Using freshly grated Parmesan cheese rather than pre-shredded cheese produces a smoother and richer sauce because it melts more evenly.

Do not overcook the pasta during boiling. Slightly undercooked pasta absorbs some of the sauce during baking and finishes with a perfect texture.

Heavy cream creates a luxurious Alfredo sauce with exceptional richness. If you want a lighter dish, you can replace some of the heavy cream with additional milk, although the sauce will be less rich.

Cook the chicken only until done. Overcooked chicken can become dry during baking.

Allowing the casserole to rest before serving helps the sauce thicken slightly and prevents it from becoming too loose on the plate.

Variations

For extra flavor, sauté sliced mushrooms and add them to the pasta mixture before baking.

Steamed broccoli makes a wonderful addition and brings freshness and color to the dish.

Cooked bacon pieces can be stirred into the sauce for a smoky and savory flavor.

A pinch of crushed red pepper flakes adds gentle heat that complements the creamy sauce beautifully.

You can replace the chicken with cooked shrimp for a seafood version of this recipe.

Storage Instructions

Allow leftovers to cool completely before storing. Transfer the casserole to an airtight container and refrigerate for up to four days.

To freeze, place portions in freezer-safe containers and freeze for up to three months. Thaw overnight in the refrigerator before reheating.

Reheat individual servings in the microwave until hot. Larger portions can be reheated in the oven at 350 degrees Fahrenheit, covered with foil, until warmed through. Adding a splash of milk or cream before reheating helps restore the creamy consistency.
