Ingredients for Chicken Alfredo Casserole

Here’s what you need to make this delicious casserole:

• 12 oz penne pasta (or any short pasta)
• 2 cups cooked chicken, shredded or diced
• 3 cups Alfredo sauce (homemade or store-bought)
• 1 ½ cups mozzarella cheese, shredded
• ½ cup cheddar cheese, shredded
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon Italian seasoning

Essential Kitchen Tools for Oven-Baked Chicken Alfredo Casserole

You won’t need complicated equipment to prepare this dish. Here’s what you’ll need:

• Large pot for boiling pasta
• Strainer
• Mixing bowl
• Casserole dish (9×13 recommended)
• Spatula or spoon
• Aluminum foil
• Oven

These simple tools make this recipe accessible for cooks of all skill levels.

How to Make Chicken Alfredo Casserole Step-by-Step

1. Cook the Pasta

Boil the penne pasta according to the package directions, but slightly undercook it by 1–2 minutes. This ensures the pasta doesn’t become mushy during baking.

2. Mix the Ingredients

In a large bowl, combine the cooked pasta, shredded chicken, and Alfredo sauce. Add garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix until fully coated.

3. Assemble the Casserole

Transfer the mixture into a greased casserole dish. Spread evenly, then sprinkle cheddar cheese and most of the mozzarella on top.

4. Add Extra Mozzarella for the Crust

Add a final thick layer of mozzarella cheese. This forms the golden, bubbly crust everyone loves.

5. Bake

Cover loosely with foil and bake at 350°F (175°C) for 20 minutes. Then remove the foil and bake for an additional 10–15 minutes, or until the cheese is browned and bubbling.

6. Let it Rest

Let the casserole rest for 5–10 minutes before serving. This prevents it from falling apart when sliced.
