Ingredients:

• Dry rotini pasta
• Alfredo sauce (use your favorite brand)

• Seasonings: Italian seasoning, chili powder, garlic powder, kosher salt, black pepper
• Shredded mozzarella or Italian blend cheese

How to prep chicken for casserole bake.

Unlike our chicken and rice casserole recipe, the chicken in this dish must be cooked and shredded prior to adding to the alfredo bake. You can quickly pressure cook chicken for meals like this, or to save time, buy a pre-cooked Rotisserie chicken and pull off and shred chicken.

How to Make Chicken Alfredo Casserole

First things first, preheat your oven to 425°F and grease a 9×13-inch baking dish with nonstick spray. You don’t want any of that cheese sticking to your pan!

In the prepared dish, add your uncooked pasta, Alfredo sauce, chicken broth, shredded chicken, and all the seasonings. Stir everything together so that the pasta is well-coated and the chicken is evenly distributed.

Cover the dish tightly with foil and bake for about 30-40 minutes. You’ll know it’s ready when the pasta is tender and everything is bubbling hot.

Once the casserole is baked, remove the foil and discard it. Sprinkle a generous amount of shredded cheese over the top. Pop the dish back in the oven for another 5-8 minutes until the cheese is perfectly melted. For a golden brown top, you can broil for a couple of minutes (but keep a close eye on it!).

Serve immediately while the casserole is hot and cheesy. I love pairing it with a light side, like roasted broccoli or a fresh corn salad. It’s also great with a sprinkle of shredded Parmesan and fresh parsley for a bit of color and flavor.

Expert Tips for Baked Alfredo Pasta

• Make it your own: Use any small pasta shape you like, or swap the mozzarella for cheddar or a cheese blend.
• Leftover chicken works best: Rotisserie chicken is perfect for this. It’s already cooked, shredded, and full of seasonings.
• Storage and Reheating: Store leftovers in an airtight container in the fridge. If the casserole dries out when reheating, just stir in a bit of extra Alfredo sauce, heavy whipping cream, or milk.
• Broil for a golden top: To get that restaurant-style golden cheese on top, turn on the broiler for the last minute or two—but watch it closely to avoid burning!

Frequently Asked Questions

No, the timing for this recipe requires that the chicken is cooked before adding it to the casserole. If you’re short on time, rotisserie chicken works perfectly.

Nope! That’s the beauty of a dump-and-bake recipe. The dry pasta cooks right in the Alfredo sauce and chicken broth while it bakes, making this a true one-dish meal.
