What Kind of Alfredo Sauce Should I Use?

A good Alfredo sauce makes or breaks this casserole. Homemade is always a win if you have time, with butter, garlic, heavy cream, and plenty of Parmesan. But store-bought sauces work perfectly too. Look for one with minimal ingredients and real cream for the best flavor.

Ingredients for the Easy Chicken Alfredo Casserole

• Cooked Pasta – Penne or rotini hold the sauce well. Cook al dente so it doesn’t over-soften in the oven.
• Cooked Chicken – Shredded or cubed rotisserie chicken saves time and adds deep flavor.
• Alfredo Sauce – Creamy and garlicky, this is the foundation of your casserole’s richness.
• Mozzarella Cheese – Adds that gooey, melted texture we all crave.
• Parmesan Cheese – Sharp and nutty, it balances the creaminess of the Alfredo.
• Garlic Powder – Enhances the savory depth of the dish.
• Italian Seasoning – For a herby boost that complements the sauce beautifully.
• Parsley (for garnish) – Optional, but it adds freshness and color to the baked dish.
