1. Chicken Alfredo Casserole Recipe ( Yield: 8 Servings )

Ingredients

• 16 ounce box penne pasta
• 2 tbsp olive oil
• 3 cups cubed chicken breasts
• salt and pepper, to taste
• 2 cups of alfredo sauce
• 8 ounce block cream cheese, softened to room temperature
• 1 cup whole milk
• 3 cloves garlic, minced
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 cups shredded mozzarella cheese (divided use)
• 1 cup grated parmesan cheese (divided use)
• chopped fresh parsley or dried parsley (for garnish, optional)

Instructions

Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish with cooking spray or a small amount of olive oil. Set the dish aside while preparing the casserole ingredients.

Bring a large pot of salted water to a boil. Add the penne pasta and cook according to the package instructions until al dente. The pasta should still have a slight bite because it will continue cooking in the oven later. Drain the pasta well and set it aside.

While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Add the cubed chicken breasts and season with salt and pepper to taste. Cook the chicken for about 6 to 8 minutes, stirring occasionally, until fully cooked and lightly golden on the outside. Remove the skillet from the heat once the chicken reaches an internal temperature of 165°F.

In a large mixing bowl, combine the Alfredo sauce, softened cream cheese, whole milk, minced garlic, Italian seasoning, salt, and black pepper. Stir everything together until the mixture becomes smooth and creamy. The softened cream cheese helps create a rich and velvety sauce that coats the pasta beautifully.

Add the cooked pasta and cooked chicken to the sauce mixture. Stir gently until every piece of pasta and chicken is evenly coated in the creamy Alfredo sauce. Add 1 cup of shredded mozzarella cheese and ½ cup of grated parmesan cheese to the bowl, then mix again until combined.

Transfer the pasta mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining mozzarella cheese and parmesan cheese evenly over the top. The cheese layer creates a delicious golden and bubbly crust during baking.

Place the casserole into the preheated oven and bake uncovered for 20 to 25 minutes, or until the cheese is melted and bubbling around the edges. If you prefer a slightly golden top, broil the casserole for an additional 2 to 3 minutes at the end of baking while watching carefully to prevent burning.

Remove the casserole from the oven and let it rest for about 5 minutes before serving. Garnish with chopped fresh parsley or dried parsley if desired. Serve warm and enjoy the creamy, cheesy flavors in every bite.

2. Tips for Perfect Chicken Alfredo Casserole

Use freshly shredded mozzarella cheese whenever possible. Pre-shredded cheese contains anti-caking ingredients that can affect how smoothly the cheese melts.

Cook the pasta just until al dente. Overcooked pasta may become too soft after baking in the casserole.

Allow the cream cheese to soften completely before mixing it into the sauce. This helps create a smooth and creamy texture without lumps.

Season the chicken well before cooking. Proper seasoning adds more flavor throughout the casserole.

For extra flavor, add cooked broccoli, spinach, mushrooms, or crispy bacon to the casserole mixture before baking.

If the casserole seems too thick before baking, stir in a small splash of milk to loosen the sauce slightly.

Let the casserole rest after baking. This helps the sauce thicken slightly and makes serving easier.

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven with a splash of milk to maintain creaminess.

3. Frequently Asked Questions

Can I use rotisserie chicken instead of chicken breasts?

Yes, rotisserie chicken works very well in this recipe and saves time. Simply shred or cube the cooked chicken and mix it into the casserole before baking.

Can I freeze Chicken Alfredo Casserole?

Yes, this casserole freezes well. Allow it to cool completely, then cover tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

What pasta works best for this casserole?

Penne pasta is a great choice because the sauce clings nicely to the pasta shape. Rigatoni, ziti, or rotini also work well.

How can I make the casserole lighter?

You can use reduced-fat cream cheese, low-fat milk, and a lighter Alfredo sauce. Adding vegetables like broccoli or spinach also balances the richness.

Why did my Alfredo sauce become oily after baking?

This can happen if the casserole is baked too long or at too high of a temperature. Baking at 375°F and avoiding overbaking helps keep the sauce creamy and smooth.
