First, boil the pasta in salted water until 3-4 minutes under al dente. (Check the pasta package and follow the inflictions for al dente pasta).
Next, add the chopped broccoli to the boiling water and let that cook together with the pasta for the additional time until the pasta is al dente.
Now, in a colander, drain the water from the broccoli and pasta and add them to a 9” x 13” baking dish.
Next, add the shredded chicken, alfredo sauce and season it with salt, pepper and garlic powder.
Now stir everting together until it’s evenly combined and smooth it out so the mixture is even and level.
Then, top it with grated Parmesan cheese and shredded mozzarella cheese.
Next, bake it, uncovered, at 350° for about 25 minutes or until the cheese is melted and the sides are hot and bubbly.
Finally, let it cool slightly, serve warm and enjoy!
