Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Lay the 6 dry ramen blocks in the dish side by side. Sprinkle the seasoning packet over them.
Spoon both jars of Alfredo over the noodles and spread it out evenly.
Scatter the shredded chicken on top.
Pour 1 cup of water into one empty Alfredo jar, shake it up, and pour it over the dish. Do the same with the cup of heavy cream in the other jar.
Cover everything with the mozzarella, then add Parmesan and Italian seasoning.
Bake for 45 to 50 minutes, until the noodles are soft, the sauce bubbles, and the cheese is melted and golden. If the top browns too fast, lay a loose piece of foil over it.
Let it rest for 5 minutes, then scoop and serve.
