Preheat oven to 375°F. Lightly grease a 9x13-inch glass baking dish with cooking spray or butter to prevent sticking.
02 -
In a large bowl, mix chopped cooked chicken with Alfredo sauce until well coated.
03 -
Evenly spread 1 cup of shredded mozzarella cheese on the bottom of the prepared baking dish.
04 -
Pour the chicken and Alfredo mixture into the baking dish, spreading evenly.
05 -
Cut each refrigerated biscuit into quarters for quicker baking and better texture.
06 -
Scatter biscuit pieces evenly over the chicken mixture in a single layer to allow puffing and browning.
07 -
Sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the biscuit pieces.
08 -
Loosely cover the dish with foil and bake for 20 minutes to start cooking biscuits and heat sauce.
09 -
Remove foil and bake uncovered for an additional 15–20 minutes until biscuits are golden brown, cheese is bubbly, and sauce bubbles at edges. If biscuits remain doughy, bake 5 minutes longer.

Allow the casserole to rest for 5–10 minutes to let the sauce settle for easier serving.
