How to Make Garlic Parmesan Chicken Pasta Casserole

Step 1: Prepare the Pasta and Chicken

Begin by cooking your pasta just shy of al dente according to package instructions; this prevents it from becoming mushy in the casserole. Meanwhile, season the chicken breasts with salt, pepper, and Italian seasoning before cooking in a skillet over medium heat until golden and cooked through. Set aside to cool slightly, then chop into bite-sized pieces.

Step 2: Sauté the Garlic and Make the Sauce

In the same skillet, melt butter and sauté freshly minced garlic until fragrant but not browned—this step unlocks the vibrant garlicky flavor. Slowly whisk in the heavy cream, stirring constantly, then add the Parmesan cheese. Continue stirring until the sauce thickens slightly and becomes rich and creamy.

Step 3: Combine Chicken, Pasta, and Sauce

Transfer the cooked pasta and chicken pieces into a large mixing bowl. Pour the creamy garlic Parmesan sauce over them, then add mozzarella cheese and mix gently until everything is evenly coated.

Step 4: Assemble and Bake

Pour the combined mixture into a greased casserole dish and spread it out evenly. Sprinkle additional mozzarella and Parmesan cheese on top for a beautifully melted, golden crust. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes until bubbly and golden on top.

Step 5: Rest and Serve

Allow the casserole to rest for 5 minutes so it sets slightly, making it easier to portion. Garnish with chopped fresh parsley if you like, then dig in!

Pro Tips for Making Garlic Parmesan Chicken Pasta Casserole

• Perfect pasta texture: Slightly undercook pasta to maintain firmness after baking.
• Garlic flavor balance: Don’t overcook garlic or it becomes bitter—light sautéing preserves flavor.
• Cheese layering: Mix cheese into the pasta and sauce, then top the casserole with extra for melty, golden results.
• Cream choice: Half-and-half makes a lighter sauce but heavy cream gives a richer, silkier texture.
• Rest before serving: Letting the casserole rest ensures clean, neat slices and deeper flavors.

How to Serve Garlic Parmesan Chicken Pasta Casserole

Garnishes

Fresh parsley or basil sprinkled over the top adds brightness and a touch of color, enhancing both flavor and presentation. You can also add a sprinkle of freshly cracked black pepper or a few extra shavings of Parmesan cheese for an elegant finish.

Side Dishes

This Garlic Parmesan Chicken Pasta Casserole pairs perfectly with a crisp green salad dressed lightly in lemon vinaigrette or a side of steamed broccoli to add a fresh, healthy balance. Crusty garlic bread or warm dinner rolls are also fantastic accompaniments to soak up any leftover creamy sauce.

Creative Ways to Present

For entertaining, serve the casserole in individual ramekins topped with fresh herbs and a light dusting of Parmesan. You can also layer additional veggies or even caramelized onions on top before baking for an elevated touch that makes it look restaurant-worthy but stays simple in preparation.

Make Ahead and Storage

Storing Leftovers

Store any leftovers covered tightly in an airtight container in the refrigerator for up to 3-4 days. This allows the flavors to meld even further and makes for a quick, tasty lunch or dinner the next day.

Freezing

This Garlic Parmesan Chicken Pasta Casserole freezes nicely for up to 2 months. Freeze it before baking by assembling the casserole, covering tightly with plastic wrap and foil, then baking straight from frozen, adding extra baking time.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly, about 15-20 minutes, or microwave individual servings until hot. Adding a splash of cream or milk when reheating can help restore creamy texture.
