1Preheat your oven to 375°F (190°C).
Cook the pasta according to the package instructions until al dente. Drain and set aside.
While the pasta is cooking, cut the chicken breast into bite-sized pieces.
In a large skillet, cook the chicken over medium heat until fully cooked and no longer pink inside.
Add the alfredo sauce to the skillet with the chicken and stir to combine.
Add the cooked pasta to the skillet and mix until the pasta is well coated with the sauce.
Stir in the red pepper flakes to add a spicy kick.
Transfer the pasta and chicken mixture to a baking dish.
Sprinkle the mozzarella cheese evenly over the top of the pasta mixture.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes before serving.
