You only need 10 minutes of prep and one dish for this easy Dump-and-Bake Chicken Alfredo Pasta Casserole. You don't even have to boil the pasta!
Preheat oven to 425°F (220°C).
In a large baking dish, stir together uncooked pasta, Alfredo sauce, chicken stock, chicken and garlic. Cover tightly with aluminum foil and bake for 30 minutes.
Uncover; give the pasta a good stir. At this point you should check the pasta to make sure that it is al dente (firm but with a tender bite). I have had good luck with the 30-minute cook time; however, some readers have noted that it required about 10 or 15 minutes longer. If it’s still too hard after 30 minutes, just cover the dish and return to the oven until pasta is al dente. Then move on to the next step.
Sprinkle mozzarella over the top. Bake uncovered for 8-10 more minutes (or until cheese is melted and pasta is tender).
Garnish with freshly grated Parmesan or fresh chopped herbs, if desired.
