Tips for the Best Chicken Alfredo Bake

• Use rotisserie chicken for convenience
  I cooked my own chicken breast in this recipe, but feel free to use rotisserie chicken. It saves time and adds extra flavor.
• Grate your own cheese
  Freshly grated cheese melts better and creates a smoother sauce.
• Don’t overcook the pasta
  Keeping it al dente prevents the pasta from becoming mushy after baking.

If you’re craving a comforting, creamy pasta dish that’s easy enough for a weeknight but impressive enough for guests, this baked chicken and broccoli alfredo is exactly what you need. Tender pieces of chicken, perfectly cooked pasta, and fresh broccoli are coated in a rich Alfredo sauce(store-bought to make it easier), then baked under a blanket of melted cheese until golden and bubbly.

What Is Alfredo Sauce?

Alfredo sauce is a creamy white pasta sauce traditionally made with butter, Parmesan cheese, and pasta water. The modern version commonly used in the United States includes heavy cream, garlic, and Parmesan, creating a thicker and richer sauce that pairs perfectly with pasta.

This creamy garlic Parmesan sauce has become a staple for comfort food dishes and is especially popular in recipes like fettuccine Alfredo and chicken Alfredo pasta.

I used a store bought alfredo sauce in this recipe to save some time. I like the one from Trader Joe’s but I always add more seasoning when I use it. In this recipe, I combine the alfredo sauce with bone broth to make it a bit creamier, and then I add cheese throughout to add flavor. This recipe is the perfect balance of hearty, creamy, and satisfying, and it’s a great way to sneak some veggies into a family favorite. Plus, it’s ideal for meal prep, leftovers, or feeding a crowd.
