This casserole is all about creamy-meets-crispy. The sauce clings to every noodle, rich and velvety with just the right garlic hit. The chicken is tender, the pasta perfectly cooked, and the topping golden and gooey with mozzarella. Every bite is a symphony of creamy comfort and cheesy pull.

Cooking Tips & Tricks

A few tricks to help you master the bake:

• Double the sauce if you like it extra creamy.
• Use rotisserie chicken to save time on prep.
• Sprinkle breadcrumbs or extra Parmesan for a crispy topping.

What to Avoid

Keep your casserole flawless by steering clear of these:

• Overcooking pasta: It will continue cooking in the oven and can get mushy.
• Using pre-shredded cheese: Often contains anti-caking agents that affect melting.
• Skipping the seasoning: Alfredo needs salt, pepper, and herbs to shine.
• Serving too soon: Letting it rest helps everything meld.
