Ingredients You’ll Need (and Why They Work So Well Together)

Let’s break down the simple, no-fuss ingredients that come together in this magic casserole:

• 2 cups cooked, shredded chicken – Use rotisserie chicken for convenience or leftover baked chicken for less waste. Either way, you get tender, flavorful protein with zero extra work.
• 1 (16 oz) box uncooked rotini pasta – Rotini’s corkscrew shape holds onto the sauce beautifully, making each bite creamy and satisfying.
• 1 (22 oz) jar Alfredo sauce (or 1½ 15 oz jars) – Store-bought Alfredo works perfectly here, especially when you’re short on time. If you’re feeling fancy, you can make your own (more on that later).
• 3 cups chicken broth – This helps cook the pasta while infusing it with deep, savory flavor.
• 2 cups shredded mozzarella cheese – For that gooey, golden topping that makes this dish truly irresistible.
• 2 teaspoons minced garlic – A little garlic adds a huge boost of flavor and plays perfectly with the Alfredo sauce.

You might already have most of these in your pantry or fridge, which means you can whip this up on a whim. That’s part of the beauty of this Dump-and-Bake Chicken Alfredo Casserole—it’s easy, affordable, and customizable.

Step-by-Step Instructions: How to Make Dump-and-Bake Chicken Alfredo Casserole

Let’s get cooking! Here’s a closer look at how simple this really is.

Step 1: Preheat the Oven

Preheat your oven to 425°F. You want it nice and hot to ensure the pasta cooks evenly and the cheese gets golden and bubbly.

Step 2: Combine Ingredients

In a 9×13-inch baking dish, dump in the uncooked rotini, shredded chicken, Alfredo sauce, chicken broth, and minced garlic. Give it a good stir until everything is well mixed.

Step 3: Cover and Bake

Cover the dish tightly with aluminum foil—this traps steam and ensures the pasta cooks properly. Bake for 30 minutes.

Step 4: Add Cheese and Finish Baking

Remove the foil, stir the pasta again (just to make sure it’s cooking evenly), and sprinkle the mozzarella cheese over the top. Return the dish to the oven, uncovered, and bake for another 8–10 minutes, until the cheese is melted and bubbly.

Step 5: Rest and Serve

Let it sit for 5 minutes before serving. This helps the sauce thicken slightly and makes the dish easier to serve.
