Ingredients You’ll Need
- 1 (16-ounce) package uncooked rotini pasta
- 22 oz jar Alfredo sauce (about 2 1/2 cups)
- 3 cups chicken stock (or chicken broth)
- 2 cups diced or shredded rotisserie chicken (or any cooked chicken you have)
- 2 teaspoons minced garlic (about 2 big cloves)
- 2 cups shredded mozzarella cheese (or Italian blend)
- Optional for garnish: Parmesan cheese and chopped fresh herbs (basil, oregano, or parsley)
Pro Tip: Fresh herbs make you look very fancy with basically zero effort. Sprinkle some on and watch everyone’s eyes widen!
How to Make It
- Preheat your oven to 425°F. Grease a 9×13-inch baking dish.
- Dump everything into the dish. (I wasn’t kidding about “dump”!) Stir together the uncooked pasta, Alfredo sauce, chicken stock, rotisserie chicken, and minced garlic right in the dish. Make sure everything’s nice and coated.
- Cover tightly with aluminum foil. We’re creating a mini sauna so the pasta cooks to tender, creamy perfection.
- Bake covered for 30 minutes.
- Uncover, sprinkle the shredded mozzarella cheese evenly on top, and bake for another 10-15 minutes until the cheese is beautifully melted and bubbly.
- Garnish with Parmesan and herbs if you’re feeling fancy (you are).
- Let it rest for about 5 minutes after baking. This helps everything thicken up and gives the pasta time to absorb even more flavor.
Grab a fork. Dinner’s ready — and you barely lifted a finger.
Cooking Tips for the Creamiest Alfredo Bake
- Use a good-quality Alfredo sauce. It’s the backbone of the creamy alfredo bake, so pick one you actually like (or make your own if you’re feeling extra).
- Rotini rocks. The twists catch all that creamy sauce. If you substitute pasta shapes, just aim for something sturdy like penne or rigatoni.
- Don’t skip the cover. Trapping the steam is crucial to cook the pasta properly without drying it out.
- Add-ins are welcome. Want to sneak in some veggies? Toss in some frozen peas, spinach, or even steamed broccoli before baking.
Oh, and don’t stress if you peek in the oven and it looks a little soupy—the pasta will continue to soak up that luscious sauce as it rests.
A Little Story From My Kitchen
This Easy Dump-and-Bake Chicken Alfredo Pasta Casserole earned “legend” status in my house after a chaotic Tuesday when I realized (too late) that I’d promised my son I’d “make something special” for dinner. I threw this together in minutes, and you would’ve thought I’d pulled off a Michelin-star meal by the way my family reacted. The leftovers? Absolutely fought over.

FAQs About Easy Dump-and-Bake Chicken Alfredo Pasta Casserole
Can I substitute a different pasta? Absolutely! Penne or ziti work great. Just stick to similarly sized pasta for even cooking.
How do I store leftovers? Cool the casserole completely, then pop it into an airtight container. It stays happy in the fridge for up to 4 days. Reheat individual portions in the microwave or warm the whole dish in a 350°F oven until heated through.
Can I use homemade Alfredo sauce? Definitely! If you have a favorite homemade version, use about 2 1/2 cups. It adds a lovely personal touch.
Can I make this ahead of time? You sure can! Assemble the casserole (without baking), cover tightly, and refrigerate for up to 24 hours. When ready to bake, remove it from the fridge while the oven preheats, then bake as directed (you might need to add an extra 5-10 minutes).
Is it freezer-friendly? Yes! You can assemble the dish, cover it well, and freeze before baking. When ready to cook, thaw overnight in the fridge and bake as usual. It’s a great make-ahead option for busy weeks.
Whether you’re feeding a hungry crowd or just need a little weeknight magic, this Easy Dump-and-Bake Chicken Alfredo Pasta Casserole is here to save the day. Trust me—your future self will thank you. (And so will your taste buds!)
