Chicken Alfredo Bake Ingredients

• 12 ounces penne or rotini pasta
• 2 cups cooked chicken, chopped or shredded
• 2 cups Alfredo sauce
• 1 cup shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• ½ cup milk
• 2 tablespoons butter
• 2 cloves garlic, minced
• ½ teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ cup cooked broccoli, optional
• 2 tablespoons chopped fresh parsley, optional

How to Make Chicken Alfredo Bake

Step 1: Cook the Pasta

Preheat the oven to 375°F (190°C). Cook the pasta in a large pot of salted boiling water until it is just slightly firm. Drain it well and set it aside. Avoid overcooking because the pasta will soften more while it bakes.

Step 2: Prepare the Chicken

Cut the cooked chicken into small bite-sized pieces or shred it with two forks. If you are using rotisserie or leftover chicken, this step is very quick. Make sure the chicken is fully cooked before adding it to the casserole.

Step 3: Mix the Alfredo Sauce

In a large mixing bowl, combine the Alfredo sauce, milk, melted butter, garlic, Italian seasoning, salt, and black pepper. Stir until everything is smooth and well combined. The milk helps make the sauce easy to mix with the pasta.

Step 4: Combine the Ingredients

Add the cooked pasta and chicken to the bowl with the Alfredo sauce. Add cooked broccoli if desired. Gently stir everything together until the pasta and chicken are completely covered with the creamy sauce.

Step 5: Add Cheese and Bake

Transfer the mixture to a greased 9×13-inch baking dish and spread it evenly. Sprinkle the mozzarella and Parmesan cheese over the top. Bake for 20–25 minutes, or until the casserole is hot, bubbling, and the cheese is melted and lightly golden.

Step 6: Rest and Serve

Remove the Chicken Alfredo Bake from the oven and let it rest for about 5 minutes. This gives the sauce a chance to settle and makes serving easier. Sprinkle with fresh parsley if desired, then scoop onto plates and enjoy while warm.
