Creamy Chicken Alfredo Pasta Bake Recipe

There’s something about pulling a bubbling, cheesy pasta bake out of the oven that instantly makes dinner feel like an occasion, even on an ordinary Tuesday. This chicken Alfredo bake is rich, creamy, and comforting enough to feel like a genuine treat, while still being simple enough to pull together without much fuss.
It’s the kind of dish that works equally well for a quiet family dinner or for guests you want to impress without spending all evening in the kitchen. Here’s exactly how I make it.
What You’ll Need (serves 6)
- 12 ounces penne pasta
- 2 cups cooked chicken breast, shredded or diced
- 2 cups Alfredo sauce (homemade or store-bought)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 teaspoon garlic powder
- ½ teaspoon Italian seasoning
- Salt and black pepper, to taste
- Fresh parsley, for garnish (optional)
How to Make It
1. Preheat and prep.
Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Cook the pasta.
Cook the penne in salted water according to the package instructions until al dente, then drain well and set aside.
3. Combine the filling.
In a large bowl, mix the cooked pasta, chicken, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper until everything’s evenly coated. Stir in half of the mozzarella and half of the Parmesan.
4. Assemble.
Transfer the mixture into your prepared baking dish and spread it out evenly. Top with the remaining mozzarella and Parmesan.
5. Bake.
Bake for 20–25 minutes, until hot and bubbling with a lightly golden top.
6. Rest and serve.
Let the pasta bake rest for 5 minutes before serving — this helps everything set properly rather than sliding apart on the plate. Garnish with fresh parsley if you’d like.
Easy Ways to Customize
This one’s flexible enough to fit whatever you’ve got on hand. Rotisserie chicken speeds things up considerably if you’re short on time. Swap the penne for rigatoni, ziti, or fusilli — anything that holds a creamy sauce well works here. Steamed broccoli adds a vegetable component without much extra effort, sautéed mushrooms deepen the flavor, grilled chicken adds a smoky note, and a pinch of red pepper flakes brings a little heat if that’s your preference.
Tips for Success
Don’t overcook the pasta before baking — al dente is exactly right, since it’ll continue softening in the oven. Freshly grated Parmesan makes a noticeable difference in both flavor and texture compared to the pre-shredded kind. Let the casserole rest before serving so it holds together properly when sliced, and if the sauce looks a little thick before baking, a small splash of milk loosens it back up. This dish also assembles well ahead of time — cover and refrigerate until you’re ready to bake. Saving a bit of extra cheese for the very top is what gives you that beautifully golden, bubbly finish.
Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave, or warm larger portions in the oven at 350°F until heated through. This pasta bake also freezes well for up to 2 months — wrap it tightly and thaw overnight in the fridge before reheating.
A Few Common Questions
Can I make this ahead of time? Yes — assemble the casserole up to 24 hours in advance, cover, and refrigerate until you’re ready to bake.
Can I use store-bought Alfredo sauce? Absolutely, a good-quality jarred sauce works perfectly and saves time.
What pasta works best? Penne, rigatoni, ziti, and fusilli all hold the creamy sauce nicely.
Can I freeze it? Yes — either before or after baking, for up to 2 months in an airtight container.
Why This One Keeps Making It Back Into the Rotation
What makes this bake worth repeating is how effortlessly it delivers comfort food without demanding much of you — a handful of ingredients, one baking dish, and a genuinely satisfying result. It’s the kind of recipe that turns an average weeknight into something the whole table actually looks forward to.
