- 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 pasta (penne, rotini, rigatoni, or fettuccine)
- Water for boiling
- 1 tablespoon salt
For the Alfredo Sauce
- 4 tablespoons butter
- 4 garlic cloves, 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 the Topping
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 tablespoons chopped fresh parsley
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a large baking dish with butter or cooking spray and set it aside. Preparing the dish in advance helps prevent sticking and ensures easy serving later.
Step 2: Cook the Pasta
Bring a large pot of water to a rolling boil. Add the salt and then the pasta. Cook the pasta until it is slightly under al dente, as it will continue cooking while baking. Once cooked, drain the pasta well and set it aside.
Step 3: Season the Chicken
Place the chicken pieces in a large bowl. Add the salt, black pepper, garlic powder, onion powder, and Italian seasoning. Toss everything together until the chicken is evenly coated with the seasonings.
Step 4: Cook the Chicken
Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook for 6 to 8 minutes, stirring occasionally, until the chicken is golden and fully cooked. Remove the chicken from the skillet and set it aside.
Step 5: Start the Alfredo Sauce
Using the same skillet, reduce the heat to medium and add the butter. Once melted, stir in the minced garlic and cook for about 1 minute, stirring constantly until fragrant.
Step 6: Add the Cream and Seasonings
Slowly pour the heavy cream and milk into the skillet, stirring continuously. Add the salt, black pepper, and Italian seasoning. Allow the mixture to simmer gently for 3 to 5 minutes until it begins to thicken slightly.
Step 7: Add the Cheese
Reduce the heat to low and gradually stir in the Parmesan cheese until fully melted. Add the mozzarella cheese and continue stirring until the sauce becomes smooth, creamy, and well combined.
Step 8: Combine the Chicken and Pasta
Return the cooked chicken to the skillet and stir until coated in the Alfredo sauce. Add the cooked pasta and gently mix until every piece is covered with the creamy sauce.
Step 9: Assemble the Casserole
Transfer the chicken and pasta mixture to the prepared baking dish. Spread it evenly across the dish. Sprinkle the mozzarella cheese over the top, followed by the Parmesan cheese to create a flavorful cheesy crust.
Step 10: Bake
Place the baking dish in the preheated oven and bake for 25 to 30 minutes, or until the casserole is bubbling around the edges and the cheese topping is melted and lightly golden.
Step 11: Rest the Casserole
Remove the casserole from the oven and allow it to rest for 10 minutes. This helps the sauce thicken slightly and makes serving easier.
Step 12: Garnish and Serve
Sprinkle the chopped fresh parsley over the top just before serving. Serve warm and enjoy this rich, creamy, and comforting Chicken Alfredo Pasta Bake with your favorite side dishes.
Helpful Tips for Success
Use Freshly Grated Cheese
Freshly grated Parmesan melts more smoothly than packaged shredded cheese and creates a silkier Alfredo sauce.
Don’t Overcook the Pasta
The pasta continues cooking while baking, so slightly undercooking it during boiling helps maintain the ideal texture.
Cook Chicken Just Until Done
Overcooked chicken can become dry after baking. Remove it from the skillet as soon as it reaches a safe internal temperature.
Allow the Dish to Rest
Resting the casserole before serving allows the sauce to settle and thicken, resulting in cleaner servings.
Taste and Adjust
Before assembling the casserole, taste the sauce and adjust the seasoning if needed.
Delicious Variations
Broccoli Alfredo Bake
Add 2 cups of steamed broccoli florets for extra nutrition and color.
Mushroom Chicken Alfredo
Sauté sliced mushrooms and stir them into the sauce before combining with the pasta.
Bacon Alfredo Bake
Mix in crispy bacon pieces for additional smoky flavor.
Spicy Alfredo
Add crushed red pepper flakes or a pinch of cayenne pepper to create a gentle kick.
Seafood Version
Replace the chicken with cooked shrimp for an elegant seafood-inspired meal.
Extra Cheesy Option
Add a blend of mozzarella, provolone, and Parmesan for an even richer cheese layer.
Storage Instructions
Refrigerator
Store leftovers in an airtight container for up to 4 days.
Freezer
Allow the casserole to cool completely before freezing. Store in freezer-safe containers for up to 3 months.
Reheating
For individual portions, microwave until heated through.
For larger amounts, place in a baking dish, cover with foil, and warm in a 350°F (175°C) oven until hot. A splash of milk or cream can help restore the sauce’s creamy texture.
Serving Ideas
This hearty pasta bake pairs wonderfully with:
- Garlic bread
- Caesar salad
- Garden salad with vinaigrette
- Roasted vegetables
- Steamed asparagus
- Dinner rolls
- Garlic green beans
A simple side salad helps balance the richness of the Alfredo sauce while crusty bread is perfect for soaking up every bit of the creamy goodness.
